Full textAbstract:
It is well-known that students benefit from personalised attention. However, frequently teachers are unable to provide this, most often due to time constraints. An Adaptive Hypermedia (AH) system can offer a richer learning experience, by giving personalised attention to students. The authoring process, however, is time consuming and cumbersome. Our research explores the two main aspects to authoring of AH: authoring of content and adaptive behaviour. The research proposes possible solutions, to overcome the hurdles towards acceptance of AH in education. Automation methods can help authors, for example, teachers could create linear lessons and our prototype can add content alternatives for adaptation. Creating adaptive behaviour is more complex. Rule-based systems, XML-based conditional inclusion, Semantic Web reasoning and reusable, portable scripting in a programming language have been proposed. These methods all require specialised knowledge. Hence authoring of adaptive behaviour is difficult and teachers cannot be expected to create such strategies. We investigate three ways to address this issue. 1. Reusability: We investigate limitations regarding adaptation engines, which influence the authoring and reuse of adaptation strategies. We propose a metalanguage, as a supplement to the existing LAG adaptation language, showing how it can overcome such limitations. 2. Standardisation: There are no widely accepted standards for AH. The IMSLearning Design (IMS-LD) specification has similar goals to Adaptive Educational Hypermedia (AEH). Investigation shows that IMS-LD is more limited in terms of adaptive behaviour, but the authoring process focuses more on learning sequences and outcomes. 3. Visualisation: Another way is to simplify the authoring process of strategies using a visual tool. We define a reference model and a tool, the Conceptual Adaptation Model (CAM) and GRAPPLE Authoring Tool (GAT), which allow specification of an adaptive course in a graphical way. A key feature is the separation between content, strategy and adaptive course, which increases reusability compared to approaches that combine all factors in one model.

Full textAbstract:
Although Adaptive Hypermedia (AH) can improve upon the traditional one-size-fitsall learning approach through Adaptive Educational Hypermedia (AEH), it still has problems with the authoring and delivery processes that are holding back the widespread usage of AEH. In this thesis we present the development of the Adaptive Delivery Environment (ADE) delivery system and use the lessons learnt during its development along with feedback from adaptation specification authors, researchers and other evaluations to formalise a list of essential and recommended optional features for AEH delivery engines. In addition to this we also investigate how the powerful adaptation techniques recommended in the above list and described in Brusilovsky and Knutov’s taxonomies can be implemented in a way that minimises the technical knowledge of adaptation authors needed to use these techniques. As the adaptation functionality increases, we research how a modular framework for adaptation strategies can be created to increase the reusability of parts of an AH system’s overall adaptation specification. Following on from this, we investigate how reusing these modular strategies via a pedagogically based visual editor can enable adaptation authors without programming experience to use these powerful adaptation techniques.

Full textAbstract:
In a linear hypermedia system, all users are offered a standard series of hyperlinks. Adaptive Hypermedia (AH) tailors what the user sees to the user's goals, abilities, interests, knowledge and preferences. Adaptive Hypermedia is said to be the answer to the 'lost in hyperspace' phenomenon, where the user has too many hyperlinks to choose from, and has little knowledge to select the most appropriate hyperlink. AH offers a selection of links and content that is most appropriate to the current user. In an Adaptive Educational Hypermedia (AEH) course, a student's learning experiences can be personalised using a User Model (UM), which could include information such as the student's knowledge level, preferences and culture. Beside these basic components, a Goal Model (GM) can represent the goal the users should meet and a Domain Model (DM) would represent the knowledge domain. Adaptive strategies are sets of adaptive rules that can be applied to these models, to allow the personalisation of the course for students, according to their needs. From the many interacting elements, it is clear that the authoring process is a bottleneck in the adaptive course creation, which needs to be improved in terms of interoperability, usability and reuse of the adaptive behaviour (strategies). Authoring of Adaptive Hypermedia is considered to be difficult and time consuming. There is great scope for improving authoring tools in Adaptive Educational Hypermedia system, to aid already burdened authors to create adaptive courses easily. Adaptation specifications are very useful in creating adaptive behaviours, to support the needs of a group of learners. Authors often lack the time or the skills needed to create new adaptation specifications from scratch. Creating an adaptation specification requires the author to know and remember the programming language syntax, which places a knowledge barrier for the author. LAG is a complete and useful programming language, which, however, is considered too complex for authors to deal with directly. This thesis thus proposes a visual framework (LAGBlocks) for the LAG adaptation language and an authoring tool (VASE) to utilise the proposed visual framework, to create adaptive specifications, by manipulating visual elements. It is shown that the VASE authoring tool along with the visual framework enables authors to create adaptive specifications with ease and assist authors in creating adaptive specifications which promote the "separation of concern". The VASE authoring tool offers code completeness, correctness at design time, and also allows for adaptive strategies to be used within other tools for adaptive hypermedia. The goal is thus to make adaptive specifications easier, to create and to share for authors with little or no programming knowledge and experience. This thesis looks at three aspects of authoring in adaptive educational hypermedia systems. The first aspect of the thesis is concerned with problems faced by the author of an adaptive hypermedia system; the second aspect is concerned with describing the findings gathered from investigating the previously developed authoring tools; and the final aspect of the thesis is concerned with the proposal, the implementation and the evaluation of a new authoring tool that improves the authoring process for authors with different knowledge, background and experience. The purpose of the new tool, VASE, is to enable authors to create adaptive strategies in a puzzle-building manner; moreover, the created adaptive strategies could be used within (are compatible with) other systems in adaptive hypermedia, which use the LAG programming language.

Full textAbstract:
Adaptive Hypermedia allows online content to be tailored specifically to the needs of the user. This is particularly valuable in educational systems, where a student might benefit from a learning experience which only displays (or recommends) content that they need to know. Authoring for adaptive systems requires content to be divided into stand-alone fragments which must then be labelled with sufficient pedagogical metadata. Authors must also create a pedagogical strategy that selects the appropriate content depending on (amongst other things) the learner's profile. This authoring process is time-consuming and unfamiliar to most non-technical authors. Therefore, to ensure that students (of all ages, ability level and interests) can benefit from Adaptive Educational Hypermedia, authoring tools need to be usable by a range of educators. The overall aim of this thesis is therefore to identify the ways that this authoring process can be simplified. The research in this thesis describes the changes that were made to the My Online Teacher (MOT) tool in order to address issues such as functionality and usability. The thesis also describes usability and functionality changes that were made to the GRAPPLE Authoring Tool (GAT), which was developed as part of a European FP7 project. These two tools (which utilise different authoring paradigms) were then used within a usability evaluation, allowing the research to draw a comparison between the two toolsets. The thesis also describes how educators can reuse their existing non-adaptive (linear) material (such as presentations and Wiki articles) by importing content into an adaptive authoring system.

Full textAbstract:
Computer-based learning has become a common phenomenon in the modern age. Many distance-learning systems distribute educational resources on the Internet and indeed entire study programmes are now widely available online. Such a large amount of content and information can be intimidating to learners, who may exhibit different individual characteristics, such as variation in goals, interests, motivation and/or learning preferences. This suggests that a uniform approach taken by learning environments to deliver materials and resources to students is not appropriate and that personalisation of such materials/resources should address users' differences to provide a customised learning experience, thus enhancing its effectiveness, lowering drop-out rates and maintaining high student motivation. This thesis addresses the latter issue of learning preferences, specifically investigating learning styles as an adaptation mechanism for personalised computer-based learning. A number of previous studies indicated the positive effect that this kind of adaptation provides, but under closer examination these were not conducted in a scientifically rigorous manner and thus their findings are somewhat limited. This research utilises a quantitative and highly objective approach to investigate visual/verbal and sequential/global learning styles in different user groups. Three user trials were carried out to discover whether there were any benefits to using these learning styles for studying in an adapted environment. Overall, no statistically significant benefits were found and these findings now shed doubt as to whether learning styles are indeed an effective mechanism for personalised learning.

Full textAbstract:
The amount of information on the web is characterised by being enormous, as is the number of users with different goals and interests. User models have been utilized by adaptive hypermedia systems generally and adaptive educational hypermedia systems (AEHS) particularly to personalize the amount of information they have with respect to each individual's knowledge, background and goals. As a result of the research described herein, a user model called the Hybrid Model has been developed. This model is both generic and abstract, and it extends other models used by AEHS by measuring users' knowledge levels with respect to different knowledge domains simultaneously by utilising well known techniques in the world of user modelling, specifically the Overlay model (which has been modified) and the Stereotype model. Therefore, using the Hybrid Model, AEHS will not be restricted to a single knowledge domain at anyone time. Thus, by implementing the Hybrid model, those systems can manage users' knowledge globally with respect to the deployed knowledge domains. The model has been implemented experimentally in an educational hypermedia system called WHURLE (Web-based Hierarchal Universal Reactive Learning Environment) to verify its aim - managing users' knowledge globally. Moreover, this implementation has been tested successfully through a user trial as an adaptive revision guide for a Biological Anthropology Course. Furthermore, the infrastructure of the WHURLE system has been modified to embrace the objective of the Hybrid Model. This has led to a novel design that provides the system with the capability of utilising different user models easily without affecting any of its component modules.

Full textAbstract:
The field of adaptive hypermedia is a little over a decade old. It has a rich history in a range of fields such as artificial intelligence, user modelling, intelligent tutoring systems and hypertext. Early adaptive hypermedia work concentrated on application-led research; developing a range of systems for specific purposes. In 1996, Peter Brusilovsky reviewed the state-of-the-art and proposed a taxonomy of adaptive hypermedia techniques, thereby providing the means to categorise adaptive hypermedia systems. Since then, several practical frameworks for adaptive hypermedia applications have been produced, in addition to formal models for formalising adaptive hypermedia applications. This thesis presents a new framework for adaptive hypermedia systems based on agent technology, a field of research largely ignored within the adaptive community. Conceptually, this framework occupies a middle ground between the formal reference models for adaptive hypermedia and application-specific frameworks. This framework provides the means to implement formal models using variety of architectural approaches. Three novel adaptive hypermedia applications have been developed around this agent-based framework. Each system employs different architectural structures, they model the user with a variety of profiling techniques, and each provides a different set of adaptive features. The diversity of these three systems emphasises the flexibility and functionality of this proposed agent-based framework.

Full textAbstract:
In our knowledge based economy, demand for better and effective learning has led to innovative instructional technologies. However, the one-size-fit-all approach taken by many e-Learning systems is not adequate to the different requirements of people who have different goals, preferences, and previous knowledge about a subject. Many e-Learning systems have approached this problem with personalized and customized content. However, many of these systems are closely tied to one particular subject that they are trying to teach; authoring of courses on different subjects using the same framework is a difficult process. Adaptive Hypermedia is an approach in which content presentation and navigation assistance is personalized depending on the requirements of the user. The user requirements are represented using a user model, while the content is represented using a content model. By using a set of algorithms, an Adaptive Hypermedia based system is able to select the most appropriate content to be presented, as the user interacts with the system. The objective of AlcoZone is to educate all of the 5,000 freshman students of Virginia Tech about alcohol education using Adaptive Hypermedia technology, as part of the mandatory university requirement. The course presents different content to different students based on their drinking pattern. AlcoZone integrates Curriculum Sequencing, Multimedia and Interactivity, Alternate Content Explanation, and Navigational Assistance to make the course interesting for students. This research investigates the design & implementation of AlcoZone and its Adaptive Hypermedia based reusable framework for course creation and delivery.Master of Science

Full textAbstract:
In an eLearning context, Adaptive Hypermedia Systems have been developed to improve learning success by increasing learner satisfaction, learning speed, and educational effectiveness. However, creating adaptive eLearning content and structures is still a time consuming and complicated task, in particular if individual lecturers are the intended authors. The way of thinking that is needed to create adaptive structures as well as the workflows is one that lecturers are unaccustomed to. The aim of this research project is to develop a concept that helps authors create adaptive eLearning content and structures, which focuses on its applicability for lecturers as intended authors. The research is targeted at the sequencing of content, which is one of the main aspects of adaptive eLearning. To achieve this aim the problem has been viewed from the author’s side. First, in terms of complexity of thoughts and threads, explanations about content structures have been found in storytelling theory. It also provides insights into how authors work, how story worlds are created, story lines intertwined, and how they are all merged together into one content. This helps us understand how non technical authors create content that is understandable and interesting for recipients. Second, the linear structure of learning content has been investigated to extract all the information that can be used for sequencing purposes. This investigation led to an approach that combines existing models to ease the authoring process for adaptive learning content by relating linear content from different authors and therefore defining interdependencies that delinearise the content structure. The technical feasibility of the authoring methods for adaptive learning content has been proven by the implementation of the essential parts in a research prototype and by authoring content from real life lectures with the prototype’s editor. The content and its adaptive structure obtained by using the concept of this research have been tested with the prototype’s player and monitor. Additionally, authoring aspects of the concept have been shown along with practical examples and workflows. Lastly, the interviewees who took part in expert interviews have agreed that the concept significantly reduces authoring complexity and potentially increases the amount of lecturers that are able to create adaptive content. The concept represents the common and traditional authoring process for linear content to a large extent. Compared to existing approaches the additional work needed is limited, and authors do not need to delve into adaptive structures or other authors’ content structures and didactic approaches.

Full textAbstract:
Nowadays, there is a growing demand for personalization and the "one-size-fits-all" approach for hypermedia systems is no longer applicable. Adaptive hypermedia (AH) systems adapt their behavior to the needs of individual users. However due to the complexity of their authoring process and the different skills required from authors, only few of them have been proposed. These last years, numerous efforts have been put to propose assistance for authors to create their own AH. However, as explained in this thesis some problems remain.In this thesis, we tackle two particular problems. A first problem concerns the integration of authors' materials (information and user profile) into models of existing systems. Thus, allowing authors to directly reuse existing reasoning and execute it on their materials. We propose a semi-automatic merging/specialization process to integrate an author's model into a model of an existing system. Our objectives are twofold: to create a support for defining mappings between elements in a model of existing models and elements in the author's model and to help creating consistent and relevant models integrating the two models and taking into account the mappings between them.A second problem concerns the adaptation specification, which is famously the hardest part of the authoring process of adaptive web-based systems. We propose an EAP framework with three main contributions: a set of elementary adaptation patterns for the adaptive navigation, a typology organizing the proposed elementary adaptation patterns and a semi-automatic process to generate adaptation strategies based on the use and the combination of patterns. Our objectives are to define easily adaptation strategies at a high level by combining simple ones. Furthermore, we have studied the expressivity of some existing solutions allowing the specification of adaptation versus the EAP framework, discussing thus, based on this study, the pros and cons of various decisions in terms of the ideal way of defining an adaptation language. We propose a unified vision of adaptation and adaptation languages, based on the analysis of these solutions and our framework, as well as a study of the adaptation expressivity and the interoperability between them, resulting in an adaptation typology. The unified vision and adaptation typology are not limited to the solutions analysed, and can be used to compare and extend other approaches in the future. Besides these theoretical qualitative studies, this thesis also describes implementations and experimental evaluations of our contributions in an e-learning application.

Full textAbstract:
Information delivery on the Web often relies on general purpose Web pages that require the reader to adapt to them. This limitation is addressed by approaches such as spatial hypermedia and adaptive hypermedia. Spatial hypermedia augments the representation power of hypermedia and adaptive hypermedia explores the automatic modification of the presentation according to user needs. This dissertation merges these two approaches, combining the augmented expressiveness of spatial hypermedia with the flexibility of adaptive hypermedia.
This dissertation presents the Multi-model Adaptive Spatial Hypermedia framework (MASH). This framework provides the theoretical grounding for the augmentation of spatial hypermedia with dynamic and adaptive functionality and, based on their functionality, classifies systems as generative, interactive, dynamic or adaptive spatial hypermedia.
Regarding adaptive hypermedia, MASH proposes the use of multiple independent models that guide the adaptation of the presentation in response to multiple relevant factors. The framework is composed of four parts: a general system architecture, a definition of the fundamental concepts in spatial hypermedia, an ontological classification of the adaptation strategies, and the philosophy of conflict management that addresses the issue of multiple independent models providing contradicting adaptation suggestions.
From a practical perspective, this dissertation produced WARP, the first MASH-based system. WARPs novel features include spatial transclusion links as an alternative to navigational linking, behaviors supporting dynamic spatial hypermedia, and personal annotations to spatial hypermedia. WARP validates the feasibility of the multi-model adaptive spatial hypermedia and allows the exploration of other approaches such as Web-based spatial hypermedia, distributed spatial hypermedia, and interoperability issues between spatial hypermedia systems.
In order to validate the approach, a user study comparing non-adaptive to adaptive spatial hypertext was conducted. The study included novice and advanced users and produced qualitative and quantitative results. Qualitative results revealed the emergence of reading behaviors intrinsic to spatial hypermedia. Users moved and modified the objects in order to compare and group objects and to keep track of what had been read. Quantitative results confirmed the benefits of adaptation and indicated a possible synergy between adaptation and expertise. In addition, the study created the largest spatial hypertext to date in terms of textual content.

COORDENAÇÃO DE APERFEIÇOAMENTO DO PESSOAL DE ENSINO SUPERIORFINANCIADORA DE ESTUDOS E PROJETOS
A computação orientada a contexto (Context-Aware Computing) é um paradigma que se propõe a permitir que as aplicações descubram e tirem proveito das informações que as circundam em dado instante, tais como localização, recursos próximos, infra-estrutura disponível, preferências do usuário, além de outras. Muitas pesquisas realizadas nessa área estão focadas na computação móvel ou na computação ubíqua. Entretanto, mais recentemente, foi possível perceber que há vários aspectos que não estão apenas limitados ao universo da ubiqüidade e da mobilidade e que também podem beneficiar outros sistemas. Os sistemas multimídia/hipermídia mais completos devem apoiar todas as etapas que envolvem o tratamento de um documento, iniciando na sua concepção, abrangendo seu armazenamento e terminando com a apresentação do documento ao leitor (usuário final). Um requisito desejável desse tipo de sistema, em particular, diz respeito à presença de mecanismos que realizem a adaptação do documento, ou seja, que efetuem algum tipo de transformação para tornar o hiperdocumento o mais adequado ao contexto no qual ele estará sendo visualizado. Sistemas hipermídia dotados de estratégias de adaptação constituem um exemplo de aplicação orientada ao contexto. O objetivo desta dissertação é propor uma arquitetura de gerência de contexto, projetada e desenvolvida como uma estrutura independente e reutilizável por diferentes sistemas, em especial, os sistemas hipermídia. A arquitetura propõe um modelo para representação da informação contextual e uma estrutura genérica (framework) capaz de ser reutilizada e incorporada em diversas implementações.
Context Aware Computing is a paradigm that allows applications to find and take profit from information that surrounds them at a given time, such as location, nearby resources, available infra-structure, user preferences, among others. Research in this area focuses on mobile or ubiquitous computing. However, recent research indicates that several aspects of this area are not limited to mobility and ubiquity. They can also profit from systems connected to other areas. Comprehensive multimedia/hypermedia systems must support all the phases of a document treatment. The treatment must encompass authoring, as well as storage and final presentation to the reader (end user). Particularly in this type of system, it is desirable to have tools that adapt the document, that is, tools that apply transformations to the hyper-document, making it adequate to the visualization. Hypermedia systems with adaptation strategies are an example of context-aware applications. The goal of this dissertation is to create a new architecture for context management: one architecture developed and built as an independent structure that may be reused by different systems, particularly by hypermedia systems. This architecture is based on a model of context information representation and on a recyclable framework that can be incorporated to several implementations.

Abstract
The focus of this thesis is to assess factors which have an influence on the acceptance of personalized Web information systems (WIS). This study is primarily based on the widely used and accepted Technology Acceptance Model (TAM).
The qualitative part of the study presents an approach for developing dynamic Web information systems. The development process was based on the work done in the OWLA (Open Web/Wireless Adaptive Hypermedia Applications) research project in 2000–2002.
The quantitative part of the study, which includes the main objective of the study, is related to assessment of user acceptance of the given system. The researcher performed a field study in 2003 in which data was collected using a web questionnaire. The field study resulted in a sample size of 209 responses. Moreover we carried out a comparison with the 2002/2003 field study aiming to study possible differences in respondents' attitude toward personalization. The previous field study was carried out during the OWLA research project. The responses were analyzed using SPSS and AMOS.
Results of the quantitative part of the study show that the respondents accept personalization but they like to and want to adapt and personalize the content themselves. This was one of the most important findings of the study. Respondents do not want the system to provide content automatically; they want to control the content themselves. The results of the 2003 field study indicate that respondents do not consider layout adaptation, whether automatic or manual, to be important or desirable.
The formulated model reveals that perceived relevance is one of the most important aspects that have an effect on attitude toward using and intention to use the given IS. Perceived expectancy and intention to use the given WIS are significant antecedents of actual use. Perceived behavioral control and normative beliefs also have a significant effect on intention to use portal. Enjoyment has a significant effect on attitude.
Overall, we have identified in this study some significant factors which will provide useful information to IS practitioners studying the voluntary adoption of specific personalized systems. The results will also provide useful information for systems designers and will contribute towards assessing possible individual barriers to the use of personalized information systems. The study includes several proposals for future research including developing deeper understanding activities related to presented development approach, creating a more detailed view of factors which have an influence on the user's decision to use or not to use personalized information system, studying several systems.

Full textAbstract:
We launched an original large-scale experiment concerning informatics learning in French high schools. We are using the France-IOI platform to federate resources and share observation for research. The first step is the implementation of an adaptive hypermedia based on very fine grain epistemic modules for Python programming learning. We define the necessary traces to be built in order to study the trajectories of navigation the pupils will draw across this hypermedia. It may be browsed by pupils either as a course support, or an extra help to solve the list of exercises (mainly for algorithmics discovery). By leaving the locus of control to the learner, we want to observe the different trajectories they finally draw through our system. These trajectories may be abstracted and interpreted as strategies and then compared for their relative efficiency. Our hypothesis is that learners have different profiles and may use the appropriate strategy accordingly. This paper presents the research questions, the method and the expected results.

A presente tese tem como principal objetivo investigar a aplicação do princípio da relevância, proveniente da Teoria da Relevância de Sperber e Wilson (1986; 1995), em um sistema hipermidia adaptativo de apoio educacional. Essa investigação, de caráter exploratório, através de um estudo de caso, visa observar o comportamento do usuário no sistema quando são feitas sugestões de tópicos de estudo de acordo com a relevância de cada um. A relevância, uma propriedade de entradas para processos cognitivos, é uma função baseada na relação econômica de custo/benefício. Segundo a teoria, o custo é o esforço de processamento requerido para assimilar uma nova informação e o benefício, o efeito contextual obtido, ou seja, o benefício cognitivo que o indivíduo pode obter no processamento de tal informação. O sistema foi modelado com base em um framework conceitual adaptativo que previa o uso de uma ontologia de domínio como estrutura de conhecimento. Essa ontologia foi avaliada e valorada por especialistas. A instanciação deste framework aconteceu no domínio de preparação para certificação em testes de proficiência da língua japonesa. As técnicas de adaptação adotadas foram no sentido de guiar a navegação no sistema através do método de sugestão de tópicos relevantes, proposto neste trabalho. O estudo de caso consistiu em observar todo o processo de interação dos usuários com duas versões do sistema, a tradicional e a adaptativa. Os dados coletados foram analisados e interpretados com base em indicadores que consideraram, dentre outros, o comportamento navegacional e a relevância das trajetórias de aprendizagem.The main goal of this thesis consists in the investigation of the application of the principle of relevance in an adaptive hypermedia system for educational support. This principle comes from Sperber and Wilson‟s Relevance Theory (1986, 1995). This exploratory research, conducted through a case study, aims to observe users‟ behavior on the system when suggestions of topics of study according to their relevance are given. Relevance, a property of inputs to cognitive processes, is a function based on the economical cost/benefit relation. According to the theory, the cost is the processing effort required to assimilate new information and the benefit, the contextual effect obtained, ie, the cognitive benefit that the individual can get from processing such information. The system was modeled based on a conceptual adaptive framework which considered the use of a domain ontology as the knowledge structure. This ontology has been assessed and valued by experts. The instantiation of this framework took place in the area of preparation for certification of proficiency in Japanese language. The adaptation techniques were adopted in order to guide the navigation in the system through the method of suggesting relevant topics, proposed in this work. The case study was held to observe the entire interaction process of users with two versions of the system, the traditional and the adaptive ones. The data collected were analyzed and interpreted based on indicators that considered, among others, the navigational behavior and the relevance of learning paths.

Um dos motivos para o crescente desenvolvimento da área de mineração de dados encontra-se no aumento da quantidade de documentos gerados e armazenados em formato digital, estruturados ou não. A Web contribui sobremaneira para este contexto e, de forma coerente com esta situação, observa-se o surgimento de técnicas específicas para utilização nesta área, como a mineração de estrutura, de conteúdo e de uso. Pode-se afirmar que esta crescente oferta de informação na Web cria o problema da sobrecarga cognitiva. A Hipermídia Adaptativa permite minorar este problema, com a adaptação de hiperdocumentos e hipermídia aos seus usuários segundo suas necessidades, preferências e objetivos. De forma resumida, esta adaptação é realizada relacionando-se informações sobre o domínio da aplicação com informações sobre o perfil de usuários. Um dos tópicos importantes de pesquisa em sistemas de Hipermídia Adaptativa encontra-se na geração e manutenção do perfil dos usuários. Dentre as abordagens conhecidas, existe um contínuo de opções, variando desde cadastros de informações preenchidos manualmente, entrevistas, até a aquisição automática de informações com acompanhamento do uso da Web. Outro ponto fundamental de pesquisa nesta área está ligado à construção das aplicações, sendo que recursos da Web Semântica, como ontologias de domínio ou anotações semânticas de conteúdo podem ser observados no desenvolvimento de sistemas de Hipermídia Adaptativa. Os principais motivos para tal podem ser associados com a inerente flexibilidade, capacidade de compartilhamento e possibilidades de extensão destes recursos. Este trabalho descreve uma arquitetura para a aquisição automática de perfis de classes de usuários, a partir da mineração do uso da Web e da aplicação de ontologias de domínio. O objetivo principal é a integração de informações semânticas, obtidas em uma ontologia de domínio descrevendo o site Web em questão, com as informações de acompanhamento do uso obtidas pela manipulação dos dados de sessões de usuários. Desta forma é possível identificar mais precisamente os interesses e necessidades de um usuário típico. Integra o trabalho a implementação de aplicação de Hipermídia Adaptativa a partir de conceitos de modelagem semântica de aplicações, com a utilização de recursos de serviços Web, para validação experimental da proposta.One of the reasons for the increasing development observed in Data Mining area is the raising in the quantity of documents generated and stored in digital format, structured or not. The Web plays central role in this context and some specific techniques can be observed, as structure, content and usage mining. This increasing information offer in the Web brings the cognitive overload problem. The Adaptive Hypermedia permits a reduction of this problem, when the contents of selected documents are presented in accordance with the user needs, preferences and objectives. Briefly put, this adaptation is carried out on the basis of relationship between information concerning the application domain and information concerning the user profile. One of the important points in Adaptive Hypermedia systems research is to be found in the generation and maintenance of the user profiles. Some approaches seek to create the user profile from data obtained from registration, others incorporate the results of interviews, and some have the objective of automatic acquisition of information by following the usage. Another fundamental research point is related with the applications construction, where can be observed the use of Web semantic resources, such as semantic annotation and domain ontologies. This work describes the architecture for automatic user profile acquisition, using domain ontologies and Web usage mining. The main objective is the integration of usage data, obtained from user sessions, with semantic description, obtained from a domain ontology. This way it is possible to identify more precisely the interests and needs of a typical user. The implementation of an Adaptive Hypermedia application based on the concepts of semantic application modeling and the use of Web services resources that were integrated into the proposal permitted greater flexibility and experimentation possibilities.

Full textAbstract:
This study attempted to combine the benefits of multimedia learning, adaptive interfaces, and learning style theory by constructing a novel e-learning environment. The environment was designed to accommodate individual learning styles while students progressed through a computer programming course. Despite the benefits of individualised instruction and a growing worldwide e-learning market, there is a paucity of guidance on how to effectively accommodate learning styles in an online environment. Several existing learning-style adaptive environments base their behaviour on an initial assessment of the learner's profile, which is then assumed to remain stable. Consequently, these environments rarely offer the learner choices between different versions of content. However, these choices could cater for flexible learning styles, promote cognitive flexibility, and increase learner control. The first research question underlying the project asked how learning styles could be accommodated in an adaptive e-learning environment. The second question asked whether a dynamically adaptive environment that provides the learner with a choice of media experiences is more beneficial than a statically adapted environment. To answer these questions, an adaptive e-learning environment named iWeaver was created and experimentally evaluated. iWeaver was based on an introductory course in Java programming and offered learning content as style-specific media experiences, assisted by additional learning tools. These experiences and tools were based on the perceptual and information processing dimension of an adapted version of the Dunn and Dunn learning styles model. An experimental evaluation of iWeaver was conducted with 63 multimedia students. The analysis investigated the effect of having a choice of multiple media experiences (compared to having just one static media experience) on learning gain, enjoyment, perceived progress, and motivation. In addition to these quantitative measurements, learners provided qualitative feedback at the end of each lesson. Data from 27 participants were sufficiently complete to be analysed. For the data analysis, participants were divided into two groups of high and low interest in programming and Java, then into two groups of high and low experience with computers and the Internet. Both group comparisons revealed statistically significant differences for the effect of choice. Having a choice of media experiences proved beneficial for learners with low experience but detrimental for learners with high experience or interest. These findings suggest that the effect of choice appears to be strongly influenced by the learner's background. It is hypothesised that encouraging a more active learner role in educational systems would expand the positive influence of choice to a wider range of learners. The study has contributed some weight to the argument that for certain groups of learners, it is more beneficial to view learning style as a flexible, rather than a stable construct. As a practical implication, it seems advisable to collect data on prior experience, interest, and the initial learning style distribution of the target audience before developing environments comparable to iWeaver.

A Web vem se apresentando um meio cada vez mais promissor para o desenvolvimento de sistemas de ensino. Um dos grandes desafios é fazer uso das vantagens da Web, que torna a aprendizagem disponível em qualquer lugar e em qualquer momento, e criar para o aluno uma experiência de aprendizagem individualizada, que represente um significante melhoramento quando comparada à experiência de aprendizagem convencional de sala de aula. Nesse contexto, este trabalho apresenta o AdaptHA, um ambiente para autoria e ensino adaptativo na Web baseado no modelo Hyper-Automaton. Com o AdaptHA, objetiva-se colaborar para a melhoria da qualidade da educação prática pela Web. Acredita-se que isto seja possível através de um sistema de ensino que reúna ferramentas que auxiliam tanto o professor quanto o aluno, mas com um grande diferencial no que se refere à capacidade deste sistema de se adaptar às características do aluno. AdaptHA proporciona ao aluno uma experiência de aprendizagem individualizada ao apresentar o conteúdo adaptado e suportar a navegação adaptativa com base no modelo do aluno, utilizando para isto, técnicas da Hipermídia Adaptativa. Os mecanismos chave do AdaptHA que viabilizam tal adaptação são: sua estrutura do modelo do domínio, cujas principais características são flexibilidade e riqueza de metadados; e sua estrutura do modelo do aluno, que mantém o histórico detalhado de todas as interações do aluno com o ambiente. A essência deste trabalho consiste em promover um tipo de ensino que seja centrado no aluno. Entretanto, é indispensável levar em consideração que o professor possui um papel fundamental dentro do cenário educacional, sendo, portanto, imprescindível prover mecanismos que colaborem para a melhoria do seu trabalho, como por exemplo: ferramentas de autoria que facilitem a criação, manutenção e reutilização de cursos e material instrucional; e ferramentas que possibilitem o acompanhamento contínuo do desempenho dos alunos. A indisponibilidade de ferramentas que facilitam o trabalho do professor em um ambiente de ensino computadorizado, seja ele Web ou não, significa, em última instância, que a autoria de cursos e material instrucional irá exigir conhecimento de pessoal técnico, o que não é razoável. Evidentemente, este aspecto gera uma barreira quase que intransponível para a utilização desse tipo de ambiente por parte do professor. Neste sentido, o AdaptHA dispõe de um ambiente de autoria que reúne um rico conjunto de ferramentas que visa suprir essas necessidades.Web has becoming more and more a promising environment for the development of learning systems. One of the big challenges is making use of Web advantages, that makes learning available anywhere and anytime, and create to the student an individualized learning experience, that represents a significant improvement when compared to the conventional classroom learning experience. In this context, this work presents AdaptHA, a Web adaptive authorship and learning environment based on Hyper-Automaton model. With AdaptHA, the goal is to collaborate to the improvement of Web practical education quality. This is possible through a learning system that groups tools that support teacher and student, but with a great plus that refers to the ability of this system to adapt itself to the student’s characteristics. AdaptHA provides to the student an individualized learning experience by presenting content adapted and supports adaptive navigation based on student model, making use of Adaptive Hypermedia techniques. AdaptHA’s key mechanisms that turn such adaptation possible are: its domain model structure, whose main features are flexibility and a rich metadata set; and its student model structure, that keeps a detailed history of all student interactions with the environment. The essence of this work is to promote a student-centered education. However, it must be taken in consideration that the teacher performs a fundamental role in the educational setting, so, it is necessary supplying mechanisms that collaborate for the improvement of his / her work, as for instance: authorship tools that facilitate the creation, maintenance and reuse of courses and instrucional material; and tools that enable the continuous accompaniment of students performance. The unavailability of tools that facilitate teacher work in a computer-based education environment, Web or not, means that courses and instructional material authorship will require knowledge of technical staff, what is not reasonable. Obviously, this aspect creates a great barrier for the use of this kind of environment by the teacher. In this sense, AdaptHA provides an authorship environment that groups a rich set of tools that supplies these needs.

A área de pesquisa em Informática na Educação tem evoluído com a introdução da Internet e milhares de cursos baseados na Web que surgiram nos últimos anos. Entretanto, estas novas aplicações educacionais são, em muitos casos, desenvolvidas como um repositório estático de conteúdo, sem aproveitar adequadamente as características dinâmicas e de adaptabilidade que o ambiente Web propicia. Este fato ocasiona sérios problemas de usabilidade: - Problemas de orientação: uma página apresenta constantemente o mesmo conteúdo e os mesmos links, não levando em conta quais páginas são mais importantes para o aluno, dificultando a busca de informações de seu interesse. Nossa premissa é que alunos com diferentes metas e conhecimentos podem estar interessados em diferentes porções da informação apresentada em uma página hipermídia e podem utilizar diferentes links para a navegação entre as páginas. - Problemas de caminho: a navegação por caminhos totalmente livres pode ocasionar problemas de compreensão de localização. Nossa premissa é que muitas vezes é aconselhável uma determinada ordenação para percorrer um conjunto de conhecimentos, o qual é construído aos poucos, tornando-se pré-requisito para posteriores conhecimentos. No entanto, reconhecemos que a navegação arbitrária e livre não pode ser de todo abolida. Estes problemas são críticos para ambientes de educação a distância (EAD) baseados na Web. Sistemas Hipermídia Adaptativos (SHA), são sistemas que refletem algumas características dos alunos no modelo do usuário e aplicam este modelo para adaptar vários aspectos visíveis do sistema. SHA tentam superar estes problemas adaptando o conteúdo (informação) e a navegação (links) a serem apresentados para o usuário. O AdaptWeb (Ambiente de Ensino-aprendizagem Adaptativo na Web) é um sistema hipermídia adaptativo de educação a distância baseado na Web que tem como finalidade adaptar o conteúdo, a apresentação e a navegação de acordo com o modelo do usuário. O módulo de interface adaptativa descrito neste trabalho é parte integrante deste projeto e têm como finalidade adaptar a navegação do aluno de acordo com suas características descritas no modelo do usuário, além de adaptar a apresentação da interface juntamente com o módulo de adaptação de conteúdo.The research in Computer Science and Education has evolved with the introduction of the Internet and thousand of courses based on the Web that had appeared in recent years. However, these new educational applications are, in many cases, developed as a static repository of content, without using to advantage the dynamic characteristics adequately and of adaptability that the Web environment propitiates. This fact causes serious usability problems: - Orientation problems: a page constantly presents the same content and set of links, don’t taking in account which pages are more important for the student, making the search of information of his interest a very difficult task. Our premise is that students with different goals and knowledge can be interested in different portions of the information presented in a hypermedia page and they can use different links for the navigation between the pages. - Navigation problems: the navigation for totally open ways can cause problems of localization understanding. Our premise is that many times is advisable determined ordinance to cover a set of knowledge, which is constructed gradually, becoming prerequisite for posterior knowledge. However, we recognize that arbitrary and open navigation cannot of all be abolished. These problems are critical for e-learning system. Adaptive Hypermedia System (AHS) are systems that reflect some characteristics of the students in the user's model and apply this model to adapt some visible aspects of the system. AHS try to surpass these problems adapting their content (information) and their navigation (links) to be presented for the user. The AdaptWeb Environment (Adaptive Web-based learning Environment) is an adaptive e-learning system that has as purpose to adapt the content, the presentation and the navigation in accordance with the user’s model. The adaptive interface module described in this work is integrant part of the AdaptWeb project and has as purpose to adapt the student's navigation in accordance with his described characteristics in the user's model, besides together adapting the presentation of the interface with the content adaptation module.

Esta pesquisa corresponde ao estudo de técnicas de hipermídia adaptativa (HA), visando melhorias nos meios para organização e disponibilização de conteúdo jornalístico online de acordo com o comportamento e interesse individual de um usuário em busca de notícias e informação. Do ponto de vista do design, a abordagem sobre o assunto corresponde, basicamente, à busca por métodos inteligentes de alimentação de uma interface gráfica com conteúdo noticioso, baseando-se em estudos do comportamento de navegação do usuário. A idéia é que as estatísticas matemáticas deste comportamento sejam traduzidas na exibição do conteúdo para atender de forma antecipada possíveis interesses do usuário. Concentrou-se como área de interesse focal, as matérias que serão incluídas na página principal e a forma de como serão distribuídas. Para isto foram criados alguns modelos de layout para a página principal. Estes modelos de layout possuem slots (espaços) onde as notícias são inseridas. Estes slots, por sua vez, estão distribuídos hierarquicamente de tal forma que os considerados mais importantes são aqueles com fotos e localizados nas melhores posições da página. A metodologia aqui criada foi aplicada como estudo na página principal do portal www.globo.com de conteúdo predominantemente noticioso e pertencente a um dos principais grupos de empresas de comunicação do Brasil.This research concerns a methodology to organize the homepage of online news in order to adapt it according to the main interests of the users. The designers approach to this issue involves the usage of inteligent procedures based on the navigational behavior of the user and statistical analysis of such behaviour. Our main interest concerns the selection of the news to be inserted into this home page and how to distribute them. We deal with some templates for such first page. These templates have slots where news is inserted. These slots are hierarchically distributed in such a way that most important slots are those with photos and larger texts and are located in the best positions. These best slots are filled out with the most interesting news according to each users interests. This whole methodology has been applied to the journalistic site www.globo.com which belongs to a major Brazilian communication company.

Mit dem Wandel des Internets zu einer universellen Softwareplattform sind die Möglichkeiten und Fähigkeiten von Webanwendungen zwar rasant gestiegen. Gleichzeitig gestaltet sich ihre Entwicklung jedoch zunehmend aufwändig und komplex, was dem Wunsch nach immer kürzeren Entwicklungszyklen für möglichst situative, bedarfsgerechte Lösungen entgegensteht. Bestehende Ansätze aus Forschung und Technik, insbesondere im Umfeld der serviceorientierten Architekturen und Mashups, werden diesen Problemen bislang nicht ausreichend gerecht. Deshalb werden in dieser Dissertation neue Konzepte für die modellgetriebene Entwicklung und Bereitstellung von Webanwendungen vorgestellt. Die zugrunde liegende Idee besteht darin, das Paradigma der Serviceorientierung auf die Präsentationsebene zu erweitern. So sollen erstmals – neben Daten- und Geschäftslogik – auch Teile der Anwendungsoberfläche in Form wiederverwendbarer Komponenten über Dienste bereitgestellt werden. Anwendungen sollen somit über alle Anwendungsebenen hinweg nach einheitlichen Prinzipien „komponiert“ werden können. Den ersten Schwerpunkt der Arbeit bilden die entsprechenden universellen Modellierungskonzepte für Komponenten und Kompositionen. Sie erlauben u. a. die plattformunabhängige Beschreibung von Anwendungen als Komposition der o. g. Komponenten. Durch die Abstraktion und entsprechende Autorenwerkzeuge wird die Entwicklung so auch für Domänenexperten bzw. Nicht-Programmierer möglich. Der zweite Schwerpunkt liegt auf dem kontextadaptiven Integrationsprozess von Komponenten und der zugehörigen, serviceorientierten Referenzarchitektur. Sie ermöglichen die dynamische Suche, Bindung und Konfiguration von Komponenten, d. h. auf Basis der o. g. Abstraktionen können genau die Anwendungskomponenten geladen und ausgeführt werden, die für den vorliegenden Nutzer-, Nutzungs- und Endgerätekontext am geeignetsten sind. Der dritte Schwerpunkt adressiert die Kontextadaptivität der kompositen Anwendungen in Form von Konzepten zur aspektorientierten Definition von adaptivem Verhalten im Modell und dessen Umsetzung zur Laufzeit. In Abhängigkeit von Kontextänderungen können so Rekonfigurationen von Komponenten, ihr Austausch oder Veränderungen an der Komposition, z.B. am Layout oder dem Datenfluss, automatisch durchgesetzt werden. Alle vorgestellten Konzepte wurden durch prototypische Implementierungen praktisch untermauert. Anhand diverser Anwendungsbeispiele konnten ihre Validität und Praktikabilität – von der Modellierung im Autorenwerkzeug bis zur Ausführung und dynamischen Anpassung – nachgewiesen werden. Die vorliegende Dissertation liefert folglich eine Antwort auf die Frage, wie zukünftige Web- bzw. Mashup-Anwendungen zeit- und kostengünstig entwickelt sowie zuverlässig und performant ausgeführt werden können. Die geschaffenen Konzepte bilden gleichermaßen die Grundlage für eine Vielzahl an Folgearbeiten.

Les travaux de recherche de cette thèse concernent principalement l‘aide à la navigation individualisée dans un hypermédia épistémique. Nous disposons d‘un certain nombre de ressources qui peut se formaliser à l‘aide d‘un graphe acyclique orienté (DAG) : le graphe des épistèmes. Après avoir cerné les environnements de ressources et de parcours, les modalités de visualisation et de navigation, de traçage, d‘adaptation et de fouille de données, nous avons présenté une approche consistant à corréler les activités de conception ou d‘édition à celles dédiées à l‘utilisation et la navigation dans les ressources. Cette approche a pour objectif de fournir des mécanismes d‘individualisation de la navigation dans un environnement qui se veut évolutif. Nous avons alors construit des prototypes appropriés pour mettre à l‘épreuve le graphe des épistèmes. L‘un de ces prototypes a été intégré à une plateforme existante. Cet hypermédia épistémique baptisé HiPPY propose des ressources et des parcours portant sur l‘apprentissage du langage Python. Il s‘appuie sur un graphe des épistèmes, une navigation dynamique et un bilan de connaissances personnalisé. Ce prototype a fait l‘objet d‘une expérimentation qui nous a donné la possibilité d‘évaluer les principes introduits et d‘analyser certains usagesThis research work mainly concerns means of assistance in individualized navigation through an epistemic hypermedia. We have a number of resources that can be formalized by a directed acyclic graph (DAG) called the graph of epistemes. After identifying resources and pathways environments, methods of visualization and navigation, tracking, adaptation and data mining, we presented an approach correlating activities of design or editing with those dedicated to resources‘ use and navigation. This provides ways of navigation‘s individualization in an environment which aims to be evolutive. Then, we built prototypes to test the graph of epistemes. One of these prototypes was integrated into an existing platform. This epistemic hypermedia called HiPPY provides resources and pathways on Python language. It is based on a graph of epistemes, a dynamic navigation and a personalized knowledge diagnosis. This prototype, which was experimented, gave us the opportunity to evaluate the introduced principles and analyze certain uses

O Ensino à distância (EaD) procura utilizar propostas pedagógicas para desenvolver sistemas inclusivos de ensino e aprendizagem. Estas propostas tem colaborado no sucesso que a EaD tem alcançado no meio empresarial corporativo. Neste meio, a demanda por cursos de formação técnica tem sido tão alta, que as empresas envolvidas no design instrucional de EaD criaram a noção de cursos à distância expressos, ou seja, cursos cuja a concepção e elaboração
devem atender as tradicionais necessidades de rapidez do mercado de trabalho. Esta dissertação procura soluções para um tipo de ensino à distância ainda pouco explorado. O
cenário que procuramos equacionar é o do ensino de ferramentas (softwares) para desenho vetorial, onde a metodologia de ensino é parte do processo de ensino corporativo. No processo atual de ensino de ferramentas de computação gráfica, o aluno submete ao professor,
normalmente pela internet, o seu trabalho para que uma avaliação seja feita. Nesta dissertação sugerimos que este processo seja modificado de duas formas. Primeiro, no design instrucional para esta situação, trabalhamos constantemente a questão de avaliação não só na sua forma tradicional (atribuição de graus e valores) mas também como aperfeiçoamento do processo de ensino. A hipermídia adaptativa entra nesta proposta como facilitador da relação alunoprofessor-conhecimento, permitindo individualização de um ensino voltado para as massas. Em segundo lugar, propomos que a avaliação das tarefas sejam automatizada. O aluno oferece as partes (objetos) da solução que são avaliadas individualmente através de algoritmos
computacionais. Isto permite uma menor participação do professor, o que é compatível com a proposta de cursos expressos. Para que isto seja possível a tarefa proposta pelo professor é dividida em objetos componentes, sendo o aluno estimulado a criar cada objeto segundo o modelo padrão oferecido. A comparaçào de cada objeto criado pelo aluno com o padrão a ser alcançado pode ser feita por diversos algoritmos computacionais existentes ou criados
especificamente pelo autor do curso. Neste trabalho apresentamos exemplos desta abordagem e um protótipo que demonstra a viabilidade da proposta.Distance learning aims to use eduacational approaches in order to develop comprehensive courses. These approaches are some of the reasons distance learning has been widely accepted by large corporations. The nowadays matket has a steady and constant demand for technical courses and skilled employees. This demand has been so high among corporations that they have coined the term Distance Learning Express Couses for courses developed in very short time, for short term necessities. This dissertation aims to offer possibilities for a less employed type of distance learning couse. The situation we intend to deal is the teaching of graphics computing tools. In the current status of such type of distance learning course, the student submits, normally by Internet, his or her pieces of work so an evaluation of his or her performance may be made. In this dissertation we propose to change this process in two ways. First we intend to use evaluation as a pivotal part of the educational process. Evaluation is no longer used only at the end of the tasks but during the teaching procedure as student feedback. Thats the reason we also employ Adaptive Hypermedia. It makes possible a more personalized teaching and student oriented guidance. Secondly, we also suggest that tasks evaluation may become automatic. The student offers the parts (objects) of the overall solution and these parts are evaluated individually by computing algorithms. This allows less teacher participation and less type spend on evaluation. In order to do so, the teacher has to divide the task in small components (objects) and to ask the student to deal with these components as models to be achieved. The comparison of the object created by the student with the model object maybe performed by several available computing algorithms or specifically designed algorithms by the author of the course. In this work we introduce an example of this approch and a prototype which shows the feasability of our proposition.

Full textAbstract:
A major challenge that faces most families is effectively anticipating how ready to start school a given child is. Traditional tests are not very effective as they depend on the skills of the expert conducting the test. It is argued that automated tools are more attractive especially when they are extended with games capabilities that would be the most attractive for the children to be seriously involved in the test. The first part of this thesis reviews the school readiness approaches applied in various countries. This motivated the development of the sophisticated system described in the thesis. Extensive research was conducted to enrich the system with features that consider machine learning and social network aspects. A modified genetic algorithm was integrated into a web-based stealth assessment tool for school readiness. The research goal is to create a web-based stealth assessment tool that can learn the user's skills and adjust the assessment tests accordingly. The user plays various sessions from various games, while the Genetic Algorithm (GA) selects the upcoming session or group of sessions to be presented to the user according to his/her skills and status. The modified GA and the learning procedure were described. A penalizing system and a fitness heuristic for best choice selection were integrated into the GA. Two methods for learning were presented, namely a memory system and a no-memory system. Several methods were presented for the improvement of the speed of learning. In addition, learning mechanisms were introduced in the social network aspect to address further usage of stealth assessment automation. The effect of the relatives and friends on the readiness of the child was studied by investigating the social communities to which the child belongs and how the trend in these communities will reflect on to the child under investigation. The plan is to develop this framework further by incorporating more information related to social network construction and analysis. Also, it is planned to turn the framework into a self adaptive one by utilizing the feedback from the usage patterns to learn and adjust the evaluation process accordingly.

Este trabalho está inserido no projeto AdaptWeb, voltado para autoria e apresentação adaptativa de disciplinas integrantes de cursos EAD na Web. Esta pesquisa visa colaborar na definição de uma sistemática para autoria adaptativa e na especificação de uma ferramenta para autoria. Está ferramenta possibilita ao autor oferecer um mesmo conteúdo adaptado para diferentes perfis de usuários. Através da sistemática de autoria, o autor organiza e reestrutura o material instrucional de forma hierárquica, onde inicialmente classifica o material como uma estrutura de conceitos. Após a organização dos conceitos, define-se uma lista de conteúdos adicionais classificados como exemplos adicionais, exercícios e material complementar para cada conceito. Ao termino da organização do material, o autor faz uso da ferramenta de autoria, onde efetua o cadastro da disciplina e dos cursos relacionados. Na próxima etapa ele cria a estrutura de conteúdo organizado através da sistemática de autoria e relaciona o material identificado para cada conceito. Para cada item da estrutura o autor especifica para quais cursos deseja disponibilizar acesso ao conteúdo. Durante a fase de autoria toda a estrutura do conteúdo programático é armazenada em estrutura de dados em memória, sendo posteriormente armazenada em formato XML, onde são aplicados filtros para apresentação do conteúdo adaptado ao modelo do usuário. Através da sistemática e da ferramenta de autoria, é possível apresentar o conteúdo adaptados na apresentação e durante a navegação. Esta proposta foi validada através de um estudo de caso real, envolvendo a disciplina de Computação Algébrica e Numérica da Universidade Estadual de Londrina (UEL). O conteúdo desta disciplina é oferecido para três cursos universitários: Matemática, Engenharia e Ciência da Computação. Para cada curso, o autor configura uma seqüência de conceitos, com seus respectivos níveis de profundidade, bem como exemplos, exercícios e material complementar apropriado.This work is included in the AdaptWeb project, focussed toward authoring and adaptive presentation of disciplines in different courses for Web learning. This research defines a systematic for adaptive authoring and for the specification of an authoring tool, which enables the author to offer a learning content adapted for different user's profiles. Through this authoring systematic, the author organizes the learning material in a hierarchical form, classifying the material as a concepts structure. After the concepts organization, the author defines a list of additional material, as examples, exercises and supplementary material for each concept. Finally, the author uses the authoring tool, registering disciplines and courses. In the next stage, he or she creates the structure of organized content and relates the material identified for each concept. For each course structure element identified the author specifies to which courses the access to the specific content will be avaliable. The educational content structure is stored in XML format, presentation filters associated with the specific user model are applied. With the help of the authoring system and the authoring tool, it is possible to present the adapted content in the presentation mode and to customize the navigation. This proposal was validated through a real case study, involving disciplines of Algebraic and Numerical Computation at Universidade Estadual de Londrina (UEL). These disciplines are offered to three university courses: Mathematics, Engineering and Computer science.

Learning is a complex process involving many variables, including the environment, social context, educational methodologies, teachers and students knowledge, among others. Highlighting the diversity of students in this process, this work presents the development of an Adaptive Learning Object using techniques of Adaptive Hypermedia and Artificial Intelligence as well as its application in classrooms, in beginners undergraduate classes, as a case study. For this purpose, this case study focuses on the learning of Algebra and Boolean Logic concepts, which has direct application in various disciplines that belong to the curriculum of several courses, like Electrical Engineering, Computer Science, Technology in Computer Networks, Systems Analysis and Development, Telecommunications, among others. By pointing out the difficulty of learning in Boolean Algebra and Logic-based subjects, this work aims to provide an improvement of educational performance in heterogeneous classrooms. Since the learning process is a challenging, interactive and iterative activity that involves a variety of aspects, it is intended that the application of adaptive techniques to a Learning Object can facilitate the skills development process by students.
A aprendizagem é um processo complexo que envolve diversas variáveis, desde o ambiente, o contexto social, as metodologias educacionais, o conhecimento do professor e do aluno, entre outras. Destacando a heterogeneidade dos alunos nesse processo, este trabalho apresenta o desenvolvimento de um Objeto de Aprendizagem Adaptativo usando técnicas de Hipermídia Adaptativa e Inteligência Artificial, bem como sua aplicação em salas de aula, em turmas iniciantes da graduação de nível superior, como estudo de caso. Para tal finalidade, este estudo de caso concentra-se na aprendizagem de conceitos de Álgebra e Lógica Booleana, que tem aplicação direta em diversas disciplinas que compõem o currículo dos cursos de Engenharia Elétrica, Ciência da Computação, Tecnologia em Redes de Computadores, Análise e Desenvolvimento de Sistemas, Telecomunicações, entre outros. Evidenciando a dificuldade de aprendizagem dos alunos em disciplinas que utilizem Álgebra e Lógica de Boole, esta proposta de trabalho visa proporcionar a melhoria do desenvolvimento do desempenho educacional em salas de aula heterogêneas. Uma vez que o processo de aprendizagem é uma atividade desafiadora, interativa e iterativa que envolve uma variedade de aspectos, pretende-se que a aplicação de técnicas de adaptatividade a um Objeto de Aprendizagem possa facilitar o processo de desenvolvimento de competências ao educando.

A pesquisa partiu de uma revisão sobre Hipermídia Adaptativa, com um apanhado sobre os conceitos e características dos métodos e técnicas de adaptação a fim de embasar seu desenvolvimento. Após, avaliou-se o uso das metaheurísticas Algoritmo Genético, Busca Tabu e Algoritmo Memético como as ferramentas de apoio no desenvolvimento do modelo. Na sequência, as Redes de Autômatos Estocásticos nortearam a modelagem do formalismo utilizado para a retenção de conhecimento. Dessas bases, foi desenvolvida a prova de conceito. Conseguinte, apresentam-se os experimentos realizados para validação. Os resultados obtidos pelo modelo foram de boa qualidade, indo ao encontro dos objetivos da pesquisa. Como decorrência deste trabalho, obteve-se um sistema capaz de gerar layouts, contemplando as características dos usuários e seus dispositivos, sendo capaz de acompanhar uma tendência de consumo de conteúdos não só mercadológica, mas também, social.

L’objectif de cette thèse est d’identifier le profil d’utilisateur d’un hypermédia afin de l’adapter. Ceprofil est déterminé en utilisant des algorithmes d’apprentissage supervisé comme le SVM.Le modèle d’utilisateur est l’un des composants essentiels des hypermédias adaptatifs. Une des façons de caractériser ce modèle est d’associer l’utilisateur à un profil. Le Web Usage Mining (WUM)identifie ce profil à l’aide des traces de navigation. Toutefois, ces techniques ne fonctionnent généralement que sur de gros volumes de données. Dans le cadre de volumes de données réduits, nous proposons d’utiliser la structure et le contenu de l’hypermédia. Pour cela, nous avons utilisé des algorithmes d’apprentissage à noyau pour lesquels nous avons défini l’élément clé qu’est la mesure de similarité entre traces basée sur une « distance » entre documents du site. Notre approche a été validée à l’aide de données synthétiques puis à l’aide de données issues des traces des utilisateurs du site Hypergéo (site webencyclopédique spécialisé dans la géographie). Nos résultats ont été comparés à ceux obtenus à l’aide d’une des techniques du WUM (l’algorithme des motifs caractéristiques). Finalement, nos propositions pour identifier les profils a posteriori ont permis de mettre en évidence cinq profils. En appliquant une« distance sémantique » entre documents, les utilisateurs d’Hypergéo ont été classés correctement selon leurs centres d’intérêtThis thesis is devoted to identify the profile of hypermedia user, then to adapt it according to user’s profile. This profile is found by using supervised learning algorithm like SVM. The user model is one of the essential components of adaptive hypermedia. One way to characterize this model is to associate a user to a profile. Web Usage Mining (WUM) identifies this profile from traces. However, these techniques usually operate on large mass of data. In the case when not enough data are available, we propose to use the structure and the content of the hypermedia. Hence, we used supervised kernel learning algorithms for which we have defined the measure of similarity between traces based on a “distance” between documents of the site. Our approach was validated using synthetic data and then using real data from the traces of Hypergéo users, Hypergéo is an encyclopedic website specialized in geography. Our results were compared with those obtained using a techniques of WUM(the algorithm of characteristic patterns). Finally, our proposals to identify the profiles a posteriori led usto highlight five profiles. Hypergéo users are classified according to their interests when the “semantic distance” between documents is applied

Atualmente há uma demanda crescente por aplicações hipermídia baseadas na WWW (World Wide Web), conhecidas como WIS (Web Information Systems). Esse novo tipo de aplicação apresenta requisitos adicionais aos sistemas de software clássicos, o que resulta na necessidade de investigar modelos mais adequados para apoiar o seu desenvolvimento. Em especial, os sistemas para apoio ao EaD (Ensino a Distância) baseados na Web apresentam características e requisitos ainda mais específicos. Os modelos atuais para modelagem e especificação de hiperdocumentos não são completamente adequados para representar características deste domínio, como a necessidade de acompanhamento dos aprendizes e a realização de avaliações diagnósticas e formativas. Isso motivou a proposta de um modelo para apoiar WISs voltados especificamente para EaD, denominado MDE (Modelo para Documentos Educacionais), que estende o modelo HMBS (Hyperdocument Model Based on Statecharts) para a descrição de conteúdo nesse domínio. O MDE adota como modelo formal subjacente uma variante da técnica Statecharts, cuja estrutura e semântica operacional possibilitam especificar a estrutura organizacional e a semântica navegacional de hiperdocumentos complexos. Adicionalmente, foi integrada ao MDE a técnica de mapeamento conceitual, que acrescenta um significado educacional aos grafos hierárquicos. Dessa forma, o modelo apresenta como pontos fortes a possibilidade de captar várias informações relevantes do comportamento do usuário no estudo do material disponível on-line e a disponibilização desses dados ao instrutor, como importante apoio à avaliação formativa. Como prova de conceito, foi desenvolvido o protótipo de um ambiente para autoria e oferecimento de cursos denominado ATEnA (Ambiente para Treinamento, Ensino e Aprendizagem). Esta tese apresenta também avaliações conceituais e práticas do modelo e do protótipo desenvolvidos.There is an increasing demand for hypermedia applications based on the WWW (World Wide Web), known as Web Information Systems (WIS). These applications present specific requirements in addition to those of traditional software systems, thus fostering the need for investigating suitable models to support their development. In particular, systems for Distance Education based on the Web present very specific characteristics and requirements. Current models for hyperdocument modeling and specification are not completely suitable for representing domain specific characteristics such as the need of tracking student progress and evaluating their learning process through diagnostic and formative assessments. This scenario motivated the proposal of a model to support WISs targeted at distance education, called MDE (Model for Distance Education). MDE extends the HMBS (Hyperdocument Model Based on Statecharts) hyperdocument model to describe hypertext content in the educational domain. It adopts as its underlying model a variant of the Statecharts formal specification technique, whose organizational structure and operational semantics allows defining the organizational structure and navigational semantics of complex hyperdocuments. MDE also incorporates the technique of conceptual mapping, that adds educational meaning to hierarchical graphs. MDEs major strengths are thus the ability to capture relevant information about user behavior when studying on-line educational material and make such information available to the teacher / instructor in order to support formative assessment of students. As a proof of concept, the prototype of an environment for authoring and offering distance courses based on MDE has been developed, called ATEnA (Adaptive Training Environment with Support for Assessment). The results of practical and conceptual evaluations of the model and system developed are also presented in this thesis.

Nowadays, e-learning has become an important source of knowledge, providing content without the limitation of time or space. In this context, Web-based education became an important sector. A large number of e-learning applications have utilized the Web to teach, mainly to provide distance learning. As a result of the substantial growth in elearning there has been an increase in the diversity of students that uses this environment to achieve their academic or professional backgrounds. In general, these students have di erent personal, social-cultural and cognitive characteristics. Adaptive Hypermedia Systems provide resources to assist this diverse public, they are able to consider the individual characteristics of students during the learning process. It is known that the representation of these features are often associated with uncertain and imprecise information. Given this context, this work proposes a Web-based Adaptive Educational Hypermedia System (with instructional content) that aims to personalize the process of distance learning. It has a student model that is able to represent the uncertainties related to the student's knowledge (characteristic of the students considered by the system) through the use of a Bayesian Network. This model is adjusted according to the answers provided by students in ability tests, which in turn are evaluated by a mathematical model of Item Response Theory. The experiment realized compared the results obtained by the proposed system, that is provided with adaptation (personalization) mechanisms, and other system that has no such mechanisms, in which the same content was presented to all the students. Statistical analysis of the collected data has shown a signi cant improvement in knowledge retention by the students who used the system provided with adaptation. However, it was expected, as a result of this improvement, that the levels of satisfaction reported by the students who used the proposed system were better than the levels reported by the students who used the system without adaptation, which was not evidenced by the gathered data.
Hoje em dia, o e-learning se tornou uma importante vertente na obtenção de conhecimento, fornecendo conteúdo sem a limitação de tempo ou espaço . Neste contexto, a educação baseada na Web tem recebido destaque. Inúmeras aplicações de e-learning tem se utilizado da Web para ensinar, principalmente para prover ensino a distancia. Como consequência do crescimento substancial do e-learning houve um aumento na diversidade dos alunos que fazem uso deste meio para a obtenção de suas formações acadêmicas ou prossionais. Em geral, estes alunos possuem diferentes características pessoais, sócio culturais e cognitivas. Os Sistemas Hiperm dia Adaptativos oferecem recursos para atender a este p ublico diverso, eles são capazes de considerar as características individuais dos alunos durante o processo de aprendizagem. Sabe-se que na representação destas características frequentemente estão associadas informações que são incertas e imprecisas. Diante do apresentado, este trabalho propõe um Sistema Hipermídia Adaptativo Educacional (com conteúdo instrucional) que tem como objetivo a personalização do processo de ensino a distância através da Web. Ele possui um modelo do aluno que e capaz de lidar com as incertezas relacionadas ao conhecimento dos alunos (caracteristica dos alunos considerada pelo sistema) através do uso de uma Rede Bayesiana. Este modelo e ajustado por respostas dadas pelos alunos em testes de habilidade, que são avaliadas por um modelo matemático da Teoria da Resposta ao Item. O experimento realizado comparou os resultados obtidos pelo sistema proposto, provido de mecanismos de adaptação (personalização), e outro sistema desprovido de adaptação, em que o mesmo conteúdo era apresentado a todos os alunos. A analise estatística dos dados coletados mostrou uma melhoria signicativa na retenção de conhecimento por parte dos alunos que zeram uso do sistema provido de adaptação. Entretanto, esperava-se, como consequência desta melhoria, que os níveis de satisfação informados pelos alunos que zeram uso do sistema proposto fossem superiores aos níveis informados pelos alunos que zeram uso do sistema desprovido de adaptação, fato não evidenciado pelos dados obtidos.

The subject of this thesis is an analysis on the effect of information granularity in adaptive hypermedia systems upon the response time in the interaction with the user. First the concept of adaptive hypermedia is brought into consideration, followed by the concept of information granularity itself. These concepts are then related to adaptive hypermedia system in order to measure the possible performance problems that can rise when information granularity is modified. Next, a methodology for performance assessment of computer systems is presented. This methodology is adapted and used to study the impact of refining information granularity upon the performance of an adaptive hypermedia system. Information is presented on the mean response time data that was collected and modeled in the form of mathematical equations, where the amount of adaptive application objects are related to average response time. An specific estimation tool was developed using these equations. The issue on performance versus optimal size for information granularity in adaptive hypermedia systems is discussed and.the conclusion suggests new directions for future work.

With the continuous migration of a great diversity of services to the Web, the need for characterizing the users in this environment increases. For that, components that can continually perceive their environment and rapidly adapt to its changes are required, thus reflecting the changes in the user behaviors. Among the existent approaches for modeling Web users, Web usage mining appears as one of the most interesting. Through Web usage mining a user can be implicitly and automatically modeled through his/her usage data, generated from his/her interaction with the Web. This work proposes ONTOWUM, a user modeling and usage mining-based multi-agent framework for Web personalization. The framework comprises two layers, where four agents are distributed according to their responsibilities: Interface agent, responsible for both capturing the user browsing information and performing the adaptation effects; User Modeling agent, responsible for creating and updating both user models and adaptation models; Acquirer agent, responsible for creating and updating an usage data repository containing past user models; and finally, Miner agent, responsible for both discovering group of users with similar browsing behavior and classifying the current user in these groups. The Interface and User modeling agents belong to the user information-processing layer, and the Acquirer and Miner agents belong to the pattern-discovering layer. The methodology and tool used to guide the analyses and design phases were MADEM ( Multi-Agent Domain Engineering Methodology ) and ONTOMADEM, respectively. For the implementation of ONTOWUM it was used the JADE framework.
Com a incessante migração das mais diversas categorias de serviços ao ambiente Web, a necessidade de caracterizar os usuários nesse ambiente nunca foi tão presente. Para isso, são necessários componentes que tenham a habilidade de continuamente perceber o ambiente e rapidamente se adaptarem a ele, refletindo assim as próprias mudanças no comportamento do usuário. Dentre as abordagens existentes para a modelagem de usuários da Web, a mineração de uso da Web figura entre as mais interessantes, pois através dessa abordagem pode-se modelar o usuário implicitamente através dos dados de uso gerados através da sua interação com a Web. Este trabalho propõe ONTOMUW", um framework multiagente para a personalização da Web baseado na modelagem de usuários e na mineração de uso. O framework é composto por duas camadas onde se distribuem quatro agentes de acordo com suas responsabilidades: agente Interfaceador, responsável tanto pela captura das informações provenientes da navegação do usuário quanto pela execução da adaptação; agente Modelador, responsável por criar e atualizar tanto modelos de usuários quanto modelos de adaptação; agente Aquisitor, responsável pela criação e manutenção de um repositório de dados de uso contendo os modelos de usuários passados; e, finalmente, agente Minerador, responsável tanto pela descoberta de grupos de usuários com comportamento de navegação similar quanto pela classificação do usuário corrente nos grupos descobertos. Os agentes Interfaceador e Modelador compõem a camada de processamento de informações do usuário, enquanto que os agentes Aquisitor e Minerador compõem a camada de descoberta de padrões. A metodologia e ferramenta utilizadas para guiar o processo de análise e projeto de domínio do ONTOMUW foram a MADEM ( Multi-Agent Domain Engineering Methodology ) e a ONTOMADEM respectivamente. Para a implementação do framework utilizou-se o ambiente JADE.

Os Sistemas de Hipermídia (SH) vem se tornando cada vez mais populares em diversas áreas de aplicação, tais como educação, marketing, comércio elétrico, informação pessoal e serviços inteligentes de interface. Atualmente um dos principais ramos da pesquisa em SH são os Sistemas de Hipermídia Adaptativa (SHA) [BRU 96] [ESP 97], juntamente com as áreas relacionadas de Modelagem do Usuário (MU) e Interfaces Inteligentes (II). Uma das características mais criticas em um SHA é o modelo do usuário, uma representação dos objetivos, conhecimento, preferências, necessidades e desejos de seus usuários. A idéia é que usuários com diferentes perfis ou modelos estarão interessados em diferentes perfis de informação dentre as apresentadas em uma página hipermídia e podem também desejar navegar no sistema através de diferentes links. A ação adaptativa em um SHA é orientada de modo a oferecer a seus usuários informação hipermídia e navegação ajustados aos respectivos modelos. A adaptação é geralmente considerada de uma forma retroativa, onde as estruturas de apresentação e navegação são produzidas como simples reações evolução passada do modelo do usuário e a oportunidades oferecidas pelo ambiente. A adaptação proativa [PAL 98] adota a idéia de seleção e mesmo a geração ativa de hiperdocumentos que serão provavelmente interessante para um determinado usuário. O uso de modelos proativos para a obtenção de informação personalizada permite a antecipação das necessidades e demandas do usuário. Isto é obtido através do emprego de algum tipo de inferência sobre os objetos hipermídia disponíveis, restrita pelo conhecimento disponível no modelo do usuário. No presente trabalho propõe-se uma metodologia para a construção de SHA, através da integração de dois modelos proativos diferentes. O primeiro desses modelos possui características conexionistas e é orientado a navegação adaptativa. Este modelo destaca a representação comportamental dos links na rede, considerando a freqüência com que estes são percorridos. O processo de modelagem é balizado pelas leis de transitividade e reflexividade, que permitem representar proativamente o hiperespaço, simplesmente através da quantização de seus links, abstraindo o conteúdo de seus nodos. O segundo modelo trata dos aspectos semânticos do processamento de informações através da lógica das situações, que oferece um arcabouço formal para a representação, composição e inferência da relação de relevância entre os nodos de sistemas de hipermídia adaptativa. O ponto de partida são os conceitos de infon, documento e descritor, assim como a semântica da relação "é sobre" que pode existir entre diferentes documentos. A integração entre os dois modelos é realizada através da sobreposição das representações em um domínio compartilhado. Uma arquitetura genérica orientada a agentes para o desenvolvimento de sistemas de HA proativa é apresentada, centrada nos processos de interfaceamento, modelagem e adaptação. A tese se completa com o projeto e desenvolvimento de um sistema educacional online com adaptação proativa para a World Wide Web. Trabalhos futuros são propostos nas áreas da educação, sistemas de informações pessoais e o trabalho colaborativo de equipes.Hypermedia Systems (HS) are becoming more and more popular in several application areas, like education, marketing, e-commerce, personal information and intelligent interface services. Currently, one of the main branches in HS research is Adaptive Hypermedia Systems (AHS) [BRU 96] [ESP 97], with its related technologies, like User Modeling (UM) and Intelligent Interfaces (II) . One of the most critical features in an AHS is the user model, a representation of the goals, knowledge, preferences, needs and desires of its users. The underlying idea is that users with different profiles or models will be interested in different pieces of information presented on a hypermedia page and may also want to use different links for navigation. The adaptation task performed by an AHS is oriented to assist users with personallytailored hypermedia information and navigation. Adaptation is in general viewed in a retroactive way where presentation and navigational structures are produced as simple reactions to the past evolution of the user model and environment opportunities. The proactive way [PAL 98] supports the idea of active selection or even the generation of hyperdocuments that will probably be interesting to a particular user. Use of proactive models in personal information gathering allows the anticipation of users needs and requests. This is achieved by applying some kind of inference over the available hypermedia objects, constrained by the knowledge present in the user model. In this work a methodology for AHS construction of is proposed, by means of the integration of two different proactive models. The first one has a conexionist trait and is oriented to adaptive navigation. This model enhances behavioral representation of the links in the network through the frequency in which they are activated. Modeling process is here controlled by the laws of transitivity and synmetry, allowing proactive representation of the hyperspace only by means of the links, with no regard for the nodes contents. The second model is related with semantic aspects of information processing through the theory of situations, which offers a formal framework for representing, composing and inference of the relevance relationship between nodes in AHS. The starting point here are the concepts of infon, document and descriptor, as the semantic of the aboutness relationship that may occur between documents. The integration of these two models is done by superposing the representations on a shared domain. An agent-oriented general architecture for the development of proactive AHS is presented, focusing interface, modeling and adaptation processes. The work is concluded with the project and development of a educational online system with proactive adaptation for the World Wide Web. Future work is proposed in the areas of education, personal information systems and collaborative development.

During the past years, the adoption of Learning Management System (LMS) to support an e-learning process has been continuously growing. Hence, a potential need and meaningful factor to provide a personalized support, within the context of these systems, has been the identification of particular characteristics of students to provide adaptations of the system’s elements to the individual traits. One particular characteristic that has been little studied in a personalized e-learning process are the learning disabilities (LD) of students. Dyslexia is a common LD in Spanish-speaking university students, which is specifically referred to the manifestation of different difficulties in reading. Dyslexia requires special attention by higher educational institutions to detect, assess, and assist affected students during their learning process. Thereby, an open challenge has been identified from this implication: How to include Spanish-speaking university students with dyslexia and/or reading difficulties in an e-learning process?Una necesidad potencial y un factor significativo para proporcionar un soporte personalizado, en el contexto de los Sistemas de Gestión del Aprendizaje (LMS), ha sido la identificación de las características de los estudiantes con el fin de proporcionar adaptaciones de los elementos del sistema a los rasgos individuales. Una característica particular que ha sido poco estudiada en un proceso de e-learning son las dificultades de aprendizaje (LD) de los estudiantes. La dislexia es una LD común en estudiantes universitarios de habla española, que se refiere específicamente a la manifestación de diferentes dificultades en la lectura. La dislexia requiere atención especial por las instituciones de educación superior para detectar, evaluar y asistir a los estudiantes afectados durante su proceso de aprendizaje. De este modo, un desafío abierto ha sido identificado: ¿Cómo incluir a los estudiantes universitarios de habla española con dislexia y/o dificultades de lectura en un proceso de e-learning?

En esta tesis se propone el uso de agentes inteligentes en entornos de aprendizaje en línea con el fin de mejorar la asistencia y motivación del estudiante a través de contenidos personalizados que tienen en cuenta el estilo de aprendizaje del estudiante y su nivel de conocimiento. Los agentes propuestos se desempeñan como asistentes personales que ayudan al estudiante a llevar a cabo las actividades de aprendizaje midiendo su progreso y motivación. El entorno de agentes se construye a través de una arquitectura multiagente llamada MASPLANG diseñada para dar soporte adaptativo (presentación y navegación adaptativa) a un sistema hipermedia educativo desarrollado en la Universitat de Girona para impartir educación virtual a través del web.
Un aspecto importante de esta propuesta es la habilidad de construir un modelo de estudiante híbrido que comienza con un modelo estereotípico del estudiante basado en estilos de aprendizaje y se modifica gradualmente a medida que el estudiante interactúa con el sistema (gustos subjetivos).
Dentro del contexto de esta tesis, el aprendizaje se define como el proceso interno que, bajo factores de cambio resulta en la adquisición de la representación interna de un conocimiento o de una actitud. Este proceso interno no se puede medir directamente sino a través de demostraciones observables externas que constituyen el comportamiento relacionado con el objeto de conocimiento. Finalmente, este cambio es el resultado de la experiencia o entrenamiento y tiene una durabilidad que depende de factores como la motivación y el compromiso.
El MASPLANG está compuesto por dos niveles de agentes: los intermediarios llamados IA (agentes de información) que están en el nivel inferior y los de Interfaz llamados PDA (agentes asistentes) que están en el nivel superior. Los agentes asistentes atienden a los estudiantes cuando trabajan con el material didáctico de un curso o una lección de aprendizaje. Esta asistencia consiste en la recolección y análisis de las acciones de los estudiantes para ofrecer contenidos personalizados y en la motivación del estudiante durante el aprendizaje mediante el ofrecimiento de contenidos de retroalimentación, ejercicios adaptados al nivel de conocimiento y mensajes, a través de interfaces de usuario animadas y atractivas. Los agentes de información se encargan del mantenimiento de los modelos pedagógico y del dominio y son los que están en completa interacción con las bases de datos del sistema (compendio de actividades del estudiante y modelo del dominio).
El escenario de funcionamiento del MASPLANG está definido por el tipo de usuarios y el tipo de contenidos que ofrece. Como su entorno es un sistema hipermedia educativo, los usuarios se clasifican en profesores quienes definen y preparan los contenidos para el aprendizaje adaptativo, y los estudiantes quienes llevan a cabo las actividades de aprendizaje de forma personalizada. El perfil de aprendizaje inicial del estudiante se captura a través de la evaluación del cuestionario ILS (herramienta de diagnóstico del modelo FSLSM de estilos de aprendizaje adoptado para este estudio) que se asigna al estudiante en su primera interacción con el sistema. Este cuestionario consiste en un conjunto de preguntas de naturaleza sicológica cuyo objetivo es determinar los deseos, hábitos y reacciones del estudiante que orientarán la personalización de los contenidos y del entorno de aprendizaje. El modelo del estudiante se construye entonces teniendo en cuenta este perfil de aprendizaje y el nivel de conocimiento obtenido mediante el análisis de las acciones del estudiante en el entorno.

Full textAbstract:
This work focuses on Web-based intelligent instructional systems and research issues associated with the development of student modeling in an adaptive hypermedia system. The framework is iMANIC (intelligent Multimedia Asynchronous Networked Individualized Courseware), in which courses originating from existing video-taped lectures provide an initial set of slides, audio, and class notes. However, the existing course structure is initially linear, which, though usable, is not optimal for a WWW presentation. Web courses are used asynchronously and thus can provide a more individualized and interactive learning experience than can live courses. Therefore, we investigate ways in which personalized instruction can be delivered via the WWW. The domain organization used in iMANIC supports a non-linear, individualized course. However, once we introduce a non-linear topic structure, the “lost in hyperspace” problem might arise, in which students become confused about what to study next and how to remember where they have been. To combat these problems, adaptive navigation techniques are used to help guide the student through the course material. The original class material is presented so that each student sees the same content. This does not take into account learning differences of individual learners. However, iMANIC can consider those differences and adapt the information presented to each user. This adaptive content is achieved through a two phase approach which considers the user's level of understanding and the content that matches the user's preferences. A Naïve Bayes Classifier is used to learn the student's preferences by observing what type of content he chooses to see. An empirical study of the iMANIC system was conducted during 2000/2001 with 24 students learning Unix Network Programming. Results from this study show distinct differences in students' learning styles and provide evidence that using the same teaching strategies for each student cannot adequately support all students. This is demonstrated through two examples. The first shows that there is not a consistent direction for the correlation between time spent studying and quiz performance. The second shows that using the same parameters for the Naïve Bayes Classifier for every student results in poor overall performance of the classifier.
