Повний текст джерелаThis research is situated in the domain of Data Warehouses (DW) personalization and concerns DW assistance. Specifically, we are interested in assisting a user during an online analysis processes to use existing operational resources. The application of this research concerns hospital management, for hospitals governance, and is limited to the scope of the Program of Medicalization of Information Systems (PMSI). This research was supported by the Public Hospitals of Marseille (APHM). Our proposal is a semantic approach based on ontologies. The support system implementing this approach, called Ontology-based Personalization System (OPS), is based on a knowledge base operated by a personalization engine. The knowledge base is composed of three ontologies: a domain ontology, an ontology of the DW structure, and an ontology of resources. The personalization engine allows firstly, a personalized search of resources of the DW based on users profile, and secondly for a particular resource, an expansion of the research by recommending new resources based on the context of the resource. To recommend new resources, we have proposed three possible strategies. To validate our proposal, a prototype of the OPS system was developed, a personalization engine has been implemented in Java. This engine exploit an OWL knowledge composed of three interconnected OWL ontologies. We illustrate three experimental scenarios related to PMSI and defined with APHM domain experts

Повний текст джерелаIn a globalized context, companies must be innovative to increase their productivity and continue to exist in an increasingly competitive market. Innovations, potential sources of profit for a company, can be at the level of a process, a new product or a service, etc. An innovative company is a company which capitalizes on its knowledge. Knowledge management (KM) is a set of approaches that can address a range of issues related to knowledge including capitalization of knowledge. However, despite the benefits and the positive impact which can have such practices on an organization, these are very little implemented. In the thesis defended in this manuscript, we are interested in improving the capitalization of knowledge and in particular the structuring of information in order to propose candidate knowledge. Our goal is to make the access to knowledge more effective to business. To do this, we must reduce the number of irrelevant results and identify the knowledge that can help business in their daily problems.By this approach, we can help an organization to optimize its feedbacks and the time spent in the different processes put in place. In order to meet these challenges, we are interested in setting up a set of elementary components, each of these components having a specific role. These components are organized as an interactive cycle. Each component will interact with others, the underlying idea is that a component improves its results by learning results from other components. Users interact directly with these components in a transparent way. To search for knowledge, the cycle scrutinizes and analyzes the behavior of users to better understand their expectations. Thus, the cycle is able to learn and improve to better capture and seek knowledge of the company. The first component is named «identification and representation of knowledge», this component has the role of exploiting a set of documents in order to extract the knowledge within this corpus. The second component aims to organize this set of documents using the knowledge extracted by the first component. The last component builds on the results provided by the previous components, the role of this component is to allow the users to be able to do a semantic search by exploiting the knowledge model built by the first component and document organization which the second component offers.This last component will aim to share knowledge, this component is not restricted to only a search, it also includes a mechanism of suggestions that assists the users in their search by offering similar documents, etc.The global approach is tested and validated with a set of documents from Reuters newspaper articles. The results of the automatic analysis are compared to the tags produced by human readers

Повний текст джерелаThrough this work, we propose some scalable and fully distributed solutions called SOCS, Adac, TRIPLET Algorithms in Autonomic Architecture of Femtocells Network such Enterprise environment, which overcome the basic challenging issues as: interference management, handover and power consumption. Based on cognitive approach, we formulate some multi-objective optimization problems with mixed integer variables for the joint power control, base station assignment, and channel assignments according to user’s QoS. Further, these schemes are subjected to various mitigating circumstances and interference-limited scenarios. The performance evaluations of these schemes are done under such conditions to ensure that they are scalable, flexible and can be considered as a practically viable option. Through this work, we try not just to improve the average throughput experienced by users according to their access level and their QoS in a femtocell, but also to propose a Handover technique that responds to the criteria imposed by the network and by the user. Furthermore, we aim in this thesis; to optimize the energy consumption in the whole network, to ensure optimal network coverage in the Enterprise, to improve the spectral efficiency and to reduce interference. Systems and techniques proposed in this thesis are designed to provide energy and spectral efficiencies by adjusting and optimizing the overall coverage of femtocells while improving the average Throughput of the system

O uso de elementos de design de jogos em contextos não relacionados a jogos, definido como gamificação, está sendo cada vez mais usado para aumentar a motivação e o engajamento dos usuários quando eles precisam executar uma tarefa em um ambiente não relacionado a jogo, como o local de trabalho, a escola ou uma aplicação de software. No entanto, quando a gamificação precisa ser implementada, um desafio enfrentado pelos desenvolvedores é identificar quais elementos do jogos engajarão efetivamente os usuários de um software com base em seus perfis de usuário e características motivacionais. Frequentemente, muitas pesquisas tendem a não incluir ou apenas apoiar os tipos de usuário e fatores motivacionais mais comuns. Em resposta a este desafio, esta dissertação propõe um modelo de gamificação genérico intitulado GamiProM que permite um desenvolvedor de software criar uma solução gamificada adaptativa para qualquer área fazendo uso de ontologias e regras, visando fornecer representação do conhecimento bem como adicionar um valor semântico à informação gerada pela gamificação e gerenciamento de perfil. O modelo é avaliado com um teste de correlação que identifica a existência de qualquer associação entre as necessidades psicológicas básicas dos usuários e suas motivações coletadas com a aplicação gamificada, desenvolvida para implementar o modelo proposto. Os resultados mostraram que as motivações coletadas dos perfis gamificados dos usuários têm uma correlação acima de 80% com as necessidades psicológicas básicas analisadas.
The use of game design elements in non-game contexts, defined as gamification, is being increasingly used to raise the motivation and engagement of users when they have to execute a task in a non-game environment, such as the workplace, the school or a software application. However, when gamification needs to be implemented, a challenge faced by developers is to identify what game elements will effectively engage the users of a software based on their user profiles and motivational characteristics. Often, many researches tend to not include or only support the most common user types and motivational factors. In response to this challenge, this thesis proposes a generic gamification model entitled GamiProM that allows a software developer to build an adaptive gamified solution for any area by making use of ontologies and rules, aiming to provide knowledge representation as well as add a semantic value to the information generated by gamification and profile management. The model is evaluated with a correlation test that identifies the existence of any association between the basic psychological needs of the users and their motivations collected with the gamified application, developed to implement the proposed model. The results showed that the motivations collected from the gamified profiles of the users have a correlation above 80% with the basic psychological needs analyzed.

Повний текст джерелаIn the current context of the Internet, a major research challenge is to enable applications and users to have their communications systems with an optimal quality of service (QoS). Indeed, QoS provisioning should take into account the available machine and network resources, which capacities and performances are heterogeneous, variable, and not known in advance. The optimal QoS provisioning for the future autonomous communication systems requires the characterization of available services and communication resources and also taking into account the expressions of needs and preferences of different actors in the system (users, service providers, etc.). The subject of this thesis deals with the definition of a QoS ontology-based semantic framework for the characterization of network resources and communication services in order to provide better QoS according to the needs and preferences of users. This framewor! k will be used in the definition of objectives and QoS constraints as well as in the development of decision models in order to provide QoS for autonomous communication systems located in the context of home networks
Lemaignan, Severin. "Grounding the interaction : knowledge management for interactive robots." Thesis, Toulouse, INSA, 2012. http://www.theses.fr/2012ISAT0010/document.
Повний текст джерелаWith the rise of the so-called cognitive robotics, the need of advanced tools to store, manipulate, reason about the knowledge acquired by the robot has been made clear. But storing and manipulating knowledge requires first to understand what the knowledge itself means to the robot and how to represent it in a machine-processable way. This work strives first at providing a systematic study of the knowledge requirements of modern robotic applications in the context of service robotics and human-robot interaction. What are the expressiveness requirement for a robot? what are its needs in term of reasoning techniques? what are the requirement on the robot's knowledge processing structure induced by other cognitive functions like perception or decision making? We propose a novel typology of desirable features for knowledge representation systems supported by an extensive review of existing tools in our community. In a second part, the thesis presents in depth a particular instantiation of a knowledge representation and manipulation system called ORO, that has been designed and implemented during the preparation of the thesis. We elaborate on the inner working of this system, as well as its integration into several complete robot control stacks. A particular focus is given to the modelling of agent-dependent symbolic perspectives and their relations to theories of mind. The third part of the study is focused on the presentation of one important application of knowledge representation systems in the human-robot interaction context: situated dialogue. Our approach and associated algorithms leading to the interactive grounding of unconstrained verbal communication are presented, followed by several experiments that have taken place both at the Laboratoire d'Analyse et d'Architecture des Systèmes at CNRS, Toulouse and at the Intelligent Autonomous System group at Munich Technical University. The thesis concludes on considerations regarding the viability and importance of an explicit management of the agent's knowledge, along with a reflection on the missing bricks in our research community on the way towards "human level robots"
Dehors, Sylvain. "Exploiting semantic web and knowledge management technologies for e-learning." Nice, 2007. http://www.theses.fr/2007NICE4006.
Повний текст джерелаThis work explores the potential applications of semantic web and knowledge management technologies for e-learning systems for accessing courses. It particularly addresses the difficult problem of reusing existing resources. In this scope, we propose a methodology and an associated system (QBLS) relying on cutting-edge semantic web tools and formalisms, that particularly develops three aspects: Reusing existing pedagogical resources through a process called "semantization". Pedagogical content is semi-automatically annotated with ontological concepts, from several points of view (domain, pedagogy, structure). It aims at contextualizing the material with regard to the teacher's conceptualization and pedagogical strategy. Exploiting annotated pedagogical resources in dynamic web interfaces. We show how semantic web technologies efficiently perform inferences based on ontological knowledge to personalize and adapt courses. The interest of semantic web standards (OWL, RDF, SPARQL) is highlighted in a practical perspective, relying on the deployment of the semantic search engine Corese. Tracking learner activity and analysis of this activity. We explore the potential of graphic based visualization and inferences to manually or automatically analyze activity traces on a semantized course. The theoretical proposal is supported by our implementation of the Question Based Learning System where learning resources available on the web are reused, annotated and exploited in real world experiments using semantic web technologies. The practical examples mentioned in this work are illustrated by two experiments conducted at the EPU of Nice Sophia-Antipolis
Triperina, Evangelia. "Visual interactive knowledge management for multicriteria decision making and ranking in linked open data environments." Thesis, Limoges, 2020. http://www.theses.fr/2020LIMO0010.
Повний текст джерелаThe dissertation herein involves research in the field of the visual representations aided by semantic technologies and ontologies in order to support decisions and policy making procedures, in the framework of research and academic information systems. The visualizations will be also supported by data mining and knowledge extraction processes in the linked data environment. To elaborate, visual analytics’ techniques will be employed for the organization of the visualizations in order to present the information in such a way that will utilize the human perceptual abilities and that will eventually assist the decision support and policy making procedures. Furthermore, the visual representation and consequently the decision and policy making processes will be ameliorated by the means of the semantic technologies based on conceptual models in the form of ontologies. Thus, the main objective of the proposed doctoral thesis consists the combination of the key semantic technologies with interactive visualisations techniques based mainly on graph’s perception in order to make decision support systems more effective. The application field will be the research and academic information systems

Повний текст джерелаThe constant evolution of technology in terms of inexpensive and embedded wireless interfaces and powerful chipsets has leads to the massive usage and development of wireless sensor networks (WSNs). This potentially affects all aspects of our lives ranging from home automation (e.g. Smart Buildings), passing through e-Health applications, environmental observations and broadcasting, food sustainability, energy management and Smart Grids, military services to many other applications. WSNs are formed of an increasing number of sensor/actuator/relay/sink devices, generally self-organized in clusters and domain dedicated, that are provided by an increasing number of manufacturers, which leads to interoperability problems (e.g., heterogeneous interfaces and/or grounding, heterogeneous descriptions, profiles, models …). Moreover, these networks are generally implemented as vertical solutions not able to interoperate with each other. The data provided by these WSNs are also very heterogeneous because they are coming from sensing nodes with various abilities (e.g., different sensing ranges, formats, coding schemes …). To tackle this heterogeneity and interoperability problems, these WSNs’ nodes, as well as the data sensed and/or transmitted, need to be consistently and formally represented and managed through suitable abstraction techniques and generic information models. Therefore, an explicit semantic to every terminology should be assigned and an open data model dedicated for WSNs should be introduced. SensorML, proposed by OGC in 2010, has been considered an essential step toward data modeling specification in WSNs. Nevertheless, it is based on XML schema only permitting basic hierarchical description of the data, hence neglecting any semantic representation. Furthermore, most of the researches that have used semantic techniques for developing their data models are only focused on modeling merely sensors and actuators (this is e.g. the case of SSN-XG). Other researches dealt with data provided by WSNs, but without modelling the data type, quality and states (like e.g. OntoSensor). That is why the main aim of this thesis is to specify and formalize an open data model for WSNs in order to mask the aforementioned heterogeneity and interoperability between different systems and applications. This model will also facilitate the data fusion and aggregation through an open management architecture like environment as, for example, a service oriented one. This thesis can thus be split into two main objectives: 1)To formalize a semantic open data model for generically describing a WSN, sensors/actuators and their corresponding data. This model should be light enough to respect the low power and thus low energy limitation of such network, generic for enabling the description of the wide variety of WSNs, and extensible in a way that it can be modified and adapted based on the application. 2)To propose an upper service model and standardized enablers for enhancing sensor/actuator discovery, data fusion, data aggregation and WSN control and management. These service layer enablers will be used for improving the data collection in a large scale network and will facilitate the implementation of more efficient routing protocols, as well as decision making mechanisms in WSNs

Повний текст джерелаThe motivation of this applied research meets a real need to improve collection, indexing and retrieval of knowledge in the field of cultural heritage. Currently, researchers in cultural heritage take much time to describe objects and transcribe them in databases. To facilitate the task of gathering information for researchers and improve performance access to knowledge, we designed and tested in real environment a system for automating the cycle of collection and storage of information and knowledge improve search. It consists of several modules, allowing achievement of the following tasks: gathering information from a dictaphone respecting a descriptive system, the transcription of spoken to the text, linguistic analysis and extraction of information and, finally, generation semi-automatic domain ontology according to a predefined conceptual model. This solution is based on techniques of signal processing, processing natural language and knowledge modeling

Повний текст джерелаDe nos jours, la complexité des systèmes implique fréquemment la participation des différentes équipes d'ingénierie dans la gestion des modèles descriptifs. Chaque équipe ayant une diversité d'expériences, de connaissances du domaine et de pratiques de modélisation, l'hétérogénéité des modèles mêmes est une conséquence logique. Ainsi, malgré la bonne gestion des modèles d'un point de vue individuel, leur variabilité devient un problème quand les ingénieurs nécessitent partager leurs modèles afin d'effectuer des validations globales. Nous défendons l'utilisation des connaissances implicites comme un moyen important de réduction de l'hétérogénéité. Ces connaissances sont implicites car elles sont dans la tête des ingénieurs mais elles n'ont pas été formalisées dans les modèles bien qu'elles soient essentielles pour les comprendre. Après avoir analysé les approches actuelles concernant l'intégration de modèles et l'explicitation de connaissances implicites nous proposons une méthodologie qui permet de compléter (annoter) les modèles fonctionnels et de conception d'un système avec des connaissances partagées du domaine formalisées sous la forme d'ontologies. Ces annotations facilitent l'intégration des modèles et la validation de contraintes intermodèles. En outre, il s'agit d'une approche non intrusive car les modèles originaux ne sont pas modifiés directement. En effet, ils sont exportés dans un environnement unifié en exprimant leurs méta-modèles dans un langage de modélisation partagé qui permet l'homogénéisation syntactique. L'approche a été validée formellement en utilisant le langage de modélisation EXPRESS en tant que langage partagé. Ensuite, afin de la valider d'un point de vue industriel, trois cas d'étude du domaine aéronautique ont été implémentés en appliquant l'approche. Cet aspect industriel a été complété par le développement d'un prototype permettant de travailler avec les ingénieurs depuis une perspective processus. Ctly modified. Thus, they are exported into a unified framework by expressing their meta-models in a shared modeling language that permits the syntactical homogenization. The approach has been formally validated by using the EXPRESS modeling language as shared language. Then, in order to validate it from an industrial point of view, three aircraft domain case studies have been implemented by applying the approach. This industrial aspect has been completed by the development of a prototype allowing engineers to work from a process perspective

Повний текст джерелаProject management or process management leads to specific organisations for which flows of knowledge and information must be usefull for organization types : traditional one (by hierarchy : business units and functions) and transversals (by work project). These flows must have different structures, representations and interpretations. Indeed, on the same corpus, different knowledge and semantics, specific to each organisation, will cross each other. Knowledge specific to each organisation of work must be formalised regarding a corresponding knowledge engineering approach. Knowledge creation is considered as an active process of memorization and (re)activation of work processes. We propose for this purpose an applicative ontology for acquisition and capitalization of business knowledge during the bidding process. The suggested ontology structures the knowledge construction as a concurrent engineering, in conformity with the experts reasoning. The experts are supports the cognitive co-operation between them. Co-operative work stands in internal negotiations about UO engagements in the product design, regarding cost and risk objectives

Повний текст джерелаThe number of activities provided by scientific workflow management systems is large, which requires scientists to know many of them to take advantage of the reusability of these systems. To minimize this problem, the literature presents some techniques to recommend activities during the scientific workflow construction. This project specified and developed a hybrid activity recommendation system considering information on frequency, input and outputs of activities and ontological annotations. Additionally, this project presents a modeling of activities recommendation as a classification problem, tested using 5 classifiers; 5 regressors; a SVM classifier, which uses the results of other classifiers and regressors to recommend; and Rotation Forest , an ensemble of classifiers. The proposed technique was compared to other related techniques and to classifiers and regressors, using 10-fold-cross-validation, achieving a MRR at least 70% greater than those obtained by other techniques

Повний текст джерелаAs the amount and the complexity of security incidents information have grown exponentially, managing and manipulating these information have become more expensive. Several security tools can be used to assist the administrators in performing these tasks. These tools can monitor what comes from Internet and goes to it, as the firewalls do; they can monitor the intranet traffic, as usually is done by an Intrusion Detection System (IDS); they can search for malicious codes in files or emails, as made by the antivirus; they can create filters to process spams, viruses or worms; or they can scan the intranet for vulnerabilities, as the scanners and the intelligent agents. These tools collect and store a great amount of information, using different formats. This lack of unique commonly agreed formats to store information about security incidents, make the administrators? job even harder, because they have to be able to understand all these formats to identify and to correlate information when, for instance, there is an attack or an invasion in progress. In this thesis I describe the design and development of ontologies to represent in a standard structure information about security incidents. The ontology developed is named OntoSec - Security Incident Ontology. This work covers: (i) how to use ontologies to share and reuse information about incidents; (ii) how to make it easier to correlate incidents; (iii) how to make it possible the interoperability amongs security tools; (iv) modeling of a security incident management system based on OntoSec; and (v) evaluation process of the ontology that has been developed. Besides that, the OntoSec aims to support the decisions made by the administrators when security problems happen, making the process more efficient and effective

Повний текст джерелаThe grid computing domain is strongly related to resource sharing for problem resolution in dynamic and heterogeneous environments. The reuse of applications stored on grids and the allocation of resources to meet application requirements are essential grid tasks. These tasks depend on the quality of available information. This work proposes a semantic approach to build a metadata service about grid models, resources and applications. This approach explores inference and queries on ontologies about applications and grid computational resources aiming to enhance the execution of grid tasks, such as resource scheduling on grids. We used InteGrade, an opportunistic grid middleware, as the ground for the development of our project. The metadata integration will contribute to promote the e_cient usage of grid resources and applications.

Повний текст джерелаThis thesis work aims at bridging the gap between the fields of Web Semantics and Experimental Particle Physics. Taking as a use case a specific type of physics experiments, namely the irradiation experiments used for assessing the resistance of components to radiation, a domain model, what in Web Semantics is called an ontology, has been created for describing the main concepts underlying the data management of irradiation experiments. Using such a formalisation, a methodology has been introduced for the automatic generation of data management systems based on ontologies and used to generate a web application for IEDM, the previously introduced ontology. In the last part of this thesis work, by the use of user-interface (UI) display preferences stored as instances of a UI-dedicated ontology we introduced, a method that represents these ontology instances as feature vectors (embeddings) for recommending personalised UIs is presented

Las contribuciones de esta tesis unen dos disciplinas: ciencias ambientales (específicamente, gestión de aguas residuales) e informática (específicamente, inteligencia artificial). El tratamiento de aguas residuales como disciplina opera utilizando un rango de diferentes enfoques y métodos que incluye: control automático on-line, modelado numérico o no-numérico, razonamiento basado en reglas, razonamiento basado en casos, soporte a la decisión y planificación. La tesis caracteriza una aplicación interdisciplinaria de técnicas de inteligencia artificial a sistemas de soporte a la decisión en el dominio ambiental. El diseño de la arquitectura de esta aplicación, el sistema OntoWEDSS, aumenta los sistemas híbridos de razonamiento ya existentes (razonamiento basado en reglas y basado en casos) con una ontología de dominio para la gestión de plantas de tratamiento de aguas residuales. La integración de la ontología WaWO, de nueva creación, proporciona a OntoWEDSS una mayor flexibilidad en la capacidad de gestión. La construcción del sistema de soporte a la decisión OntoWEDSS se basa en el estudio de un caso específico, pero el sistema resulta también es de interés general puesto que la arquitectura basada en ontologías puede aplicarse a cualquier planta de tratamiento de aguas residuales y, a un nivel apropiado de abstracción, a otros dominios ambientales. El sistema OntoWEDSS mejora la diagnosis del estado de la planta de tratamiento, proporciona soporte a la resolución de complejos problemas relacionados con aguas residuales, y facilita el modelado del conocimiento y su reutilización mediante la ontología WaWO.
En particular, la investigación ha alcanzado los siguientes objetivos: (1) la mejora del modelado de la información sobre procesos de tratamiento de aguas residuales y la clarificación de parte de la confusión existente en la terminología relacionada, (2) la incorporación de conocimiento microbiológico (referente al proceso del tratamiento y modelado mediante una ontología) dentro del proceso de razonamiento, (3) la creación de un sistema de soporte a la decisión con tres estratos (percepción, diagnosis y soporte a la decisión) que combina conocimiento mediante una novedosa integración entre KBSs y ontologías, proporcionando mejores resultados, (4) la eliminación de obstáculos existentes en el razonamiento, hallada utilizando el nuevo conocimiento microbiológico codificado en la estructura jerárquica y las relaciones de la ontología, (5) la representación de relaciones causa-efecto, debido a la implementación de un conjunto de relaciones que permiten a la ontología deducir automáticamente la respuesta a cuestiones sobre el dominio de aguas residuales.

The contributions of this thesis bridge two disciplines: environmental science (specifically, wastewater management) and computer science (specifically, artificial intelligence). Wastewater management as a discipline operates using a range of different approaches and methods which include: manual control, on-line automatic control, numerical or non-numerical models, statistical models and simulation models. The thesis characterizes an interdisciplinary research on artificial intelligence techniques (rule-based reasoning, case-based reasoning, ontologies and planning) applied to environmental decision-support systems. The integrated architecture's design of this application, the OntoWEDSS system, augments classic reasoning systems (rule-based reasoning and case-based reasoning) with a domain ontology about the management of wastewater treatment plants. The integration of the newly created WaWO ontology provides a more flexible management capability to OntoWEDSS. The construction of the OntoWEDSS decision support system is based on a specific case study but the system is also of general interest, given that its ontology-underpinned architecture can be applied to any wastewater treatment plant and, at an appropriate level of abstraction, to other environmental domains. The OntoWEDSS system improves the diagnosis of the state of a treatment plant, provides support for wastewater-related complex problem-solving, and facilitates knowledge modeling and reuse by means of the WaWO ontology.
The following research targets have been achieved in particular: (1) the improvement of the modeling of the information about wastewater treatment processes and the clarification of a part of the existing terminological confusion in the domain, (2) the incorporation of ontology-modeled microbiological knowledge related to the treatment process into the reasoning process, (3) the creation of a decision support system with three layers (perception, diagnosis and decision support) which combines knowledge through a novel integration between KBSs and ontologies, providing better results, (4) the solution of existing reasoning-impasses, found using the new microbiological knowledge encoded in the hierarchical structure and the relations of the ontology, (5) the representation of cause-effect relations, due to the implementation of a set of relations that enable the ontology to automatically deduce the answer to questions about the wastewater domain.
OntoWEDSS is implemented in the LISP programming language, using Allegro Common LISP software. A focused evaluation of the system, founded on the assessment of the capacity of response to specific problematic situations, has been carried out and has given fine results.
Questa tesi contribuisce alla intersezione di due discipline: le scienze ambientali (specificamente, la gestione delle acque di rifiuto) e la informatica (specificamente, la intelligenza artificiale). Nel trattamento delle acque di rifiuto come disciplina si utilizzano diversi metodi, che includono: controllo manuale, controllo automatico on-line, modelli numerici o non-numerici e simulazioni. La tesi caratterizza un'applicazione interdisciplinare di tecniche di intelligenza artificiale a sistemi di aiuto alla decisione in campo ambientale. L'architettura di questa applicazione, il sistema OntoWEDSS, amplia i sistemi di ragionamento ibrido esistenti (ragionamento basato su un sistema di regole, ragionamento basato sull'esperienza, aiuto alla decisione e pianificazione) con un'ontologia di dominio per la gestione di depuratori di acque di rifiuto. L'integrazione dell'ontologia WaWO, di nuova creazione, fornisce a OntoWEDSS una maggiore flessibilità nella sua capacità di gestione. La costruzione del sistema OntoWEDSS si basa sullo studio di un caso specifico, però il sistema risulta anche di interesse generale dato che l'architettura basata su un'ontologia può essere applicata a un qualsiasi depuratore e, considerando un adeguato livello d'astrazione, ad altri domini ambientali. Il sistema OntoWEDSS migliora la diagnosi dello stato del depuratore, fornisce aiuto alla soluzione di problemi complessi relazionati con le acque di rifiuto e facilita la modellizzazione della conoscenza e la sua riutilizzazione mediante l'ontologia WaWO.
In particolare, la ricerca realizzata ha raggiunto i seguenti obiettivi: (1) il miglioramento dell'informazione sui processi di depurazione e il chiarimento di parte della confusione esistente nella terminologia relativa, (2) l'incorporazione di conoscenza microbiologica (riguardo al processo di depurazione e mediante la modellizzazione ontologica) nel processo di ragionamento, (3) la creazione di un sistema di aiuto alla decisione con tre livelli (percezione, diagnosi e aiuto alla decisione) che combina la informazione mediante un nuovo tipo d'integrazione tra classici sistemi basati sulla conoscenza e ontologie, proporzionando risultati migliori, (4) l'eliminazione di alcuni ostacoli esistenti nel ragionamento, ottenuta utilizzando la nuova conoscenza microbiologica codificata nella struttura gerarchica e nelle relazioni dell'ontologia, (5) la rappresentazione di relazioni causa-effetto del mondo reale attraverso l'implementazione di un insieme di relazioni ontologiche che permettono di dedurre automaticamente le risposte a domande sul dominio delle acque di rifiuto.
OntoWEDSS è implementata nel linguaggio di programmazione LISP, usando il software Allegro Common LISP. È stata realizzata una valutazione del sistema basata sulla stima della capacità di risposta a situazioni problematiche specifiche e si sono ottenuti risultati soddisfacenti.

Повний текст джерелаA tecnologia da informação (TI) vem se tornando essencial para as organizações. Nesse contexto, o gerenciamento de TI vem evoluindo para incluir gerenciamento de serviços e governança de TI, apontando para paradigmas de gerenciamento de TI orientado ao negócio. Dessa forma, o alinhamento entre a TI e o negócio tem sido considerado como um dos fatores preponderantes para a efetividade de tais paradigmas. Em adicional, são mencionadas as contribuições provenientes da automação das atividades de gerenciamento. Acompanhando essa evolução, o gerenciamento de configuração desempenha um papel fundamental, fornecendo informações precisas da TI a todos os envolvidos no gerenciamento. Todavia, em função desse estreito relacionamento com todas as entidades ligadas ao gerenciamento, a interoperabilidade entre esses componentes tem sido caracterizada como um dos principais desafios de pesquisa em gerenciamento de redes e serviços. Nesse sentido, o uso de ontologias, em especial ontologias de fundamentação, tem sido indicado como uma maneira pro issora de se obter interoperabilidade semântica no domínio de gerenciamento de configuração, uma vez que elas expressam o significado dos conceitos do domínio, bem como os relacionamentos existentes entre eles, de forma clara e explícita. Além disso, ontologias permitem que esse significado seja definido em um formato legível por máquinas, tornando o conhecimento compartilhado não apenas por agentes humanos, mas também por sistemas computacionais, possibilitando a automação de processos. Assim, esta dissertação apresenta uma proposta de modelagem conceitual do domínio de gerenciamento de configuração, no contexto do gerenciamento de serviços e governança de TI, baseada em ontologias de fundamentação. O propósito dessa ontologia é prover um modelo conceitual desse domínio, comprometido em maximizar a expressividade, a clareza e a veracidade dos conceitos pertencentes a ele. Ademais, esta dissertação apresenta uma proposta de modelo de implementação, derivado do modelo conceitual desenvolvido. O objetivo é realizar uma prova de conceito da ontologia e também demonstrar como essa ontologia pode apoiar as atividades de gerenciamento de maneira automatizada
Information technology (IT) is becoming essential for organizations. In this context, IT management has evolved to include service management and IT governance, towards business driven IT management paradigms. Thus, the alignment between IT and business has been regarded as one of the leading factors for the effectiveness of such paradigms. Furthermore, contributions arising from management activities automation are mentioned. Following this evolution, configuration management plays a key role in providing accurate IT information to all involved in management. However, due to this close relationship with all entities related to management, interoperability among these components has been characterized as one of the main research challenges in network and service management. In this sense, the use of ontologies, foundational ontologies in particular, has been indicated as a promising way to achieve semantic interoperability in the configuration management domain, since they express the meaning of domain concepts, as well as the existing relationships between them, in a clear and explicit way. Moreover, ontologies allow that this meaning be defined in a machine readable format, making the knowledge shared not only by human agents, but also by computer systems, enabling process automation. Thus, this dissertation proposes a conceptual model of configuration management domain in the context of service management and IT governance, based on foundational ontologies. The purpose of this ontology is to provide a conceptual model of this domain, committed to maximizing the expressiveness, clarity and truthfulness of concepts that belong thereto. Moreover, this dissertation proposes an implementation model, derived from the developed conceptual model. The goal is to perform an ontology proof of concept and also demonstrate how this ontology can support the management activities in an automated way

Повний текст джерелаIn this thesis, we propose a collaborative model driven methodology for designing Autonomic Cognitive IoT systems to deal with IoT design complexity. We defined within this methodology a set of autonomic cognitive design patterns that aim at (1) delineating the dynamic coordination of the autonomic processes to deal with the system's context changeability and requirements evolution at run-time, and (2) adding cognitive abilities to IoT systems to understand big data and generate new insights. To address challenges related to big data and scalability, we propose a generic semantic big data platform that aims at integrating heterogeneous distributed data sources deployed on the cloud and generating knowledge that will be exposed as a service (Knowledge as a Service--KaaS). As an application of the proposed contributions, we instantiated and combined a set of patterns for the development of prescriptive cognitive system for the patient treatment management. Thus, we elaborated two ontological models describing the wearable devices and the patient context as well as the medical knowledge for decision-making. The proposed system is evaluated from the clinical prescriptive through collaborating with medical experts, and from the performance perspective through deploying the system within the KaaS following different configurations

Повний текст джерелаOver the last few years, the advances in management science and information technology have transformed the business process management (BPM) discipline into an important topic for both industry and academy. BPM uses business processes as the means for improving the operational performance of organizations, and setting processes are at the heart of BPM allows linking together people, systems, and different organizations to deliver value to stakeholders. The target of our work is the family of BPM systems. A BPM system is a generic software system that is driven by explicit process designs to enact and manage operational business processes. Despite the wide range of topics addressed by the academy on business processes, there are still aspects not addressed by prior research. A particular problem in this regard is the mediation between BPM systems and humans. Human interaction in those systems follows a standard user interface based predominantly on work item lists and forms. Thus, there is little room for creativity for users. They have not only difficulties in enacting their processes but also for searching the most suitable one for their needs. It would be more efficient to let humans interact in natural language. However, process modeling languages are an insufficient means of capturing and representing the domain of discourse. The present thesis develops an original approach to agent dialog management for the problem of business process enactment. The overarching motivation for this work was to design a dialog model scalable to different domains. The model relies on domain and business process ontologies, and necessitates a minimum effort of adaptation on ontologies to improve the interaction. Results indicate the potential of our agent-based approach to generate natural language

Повний текст джерелаDocumentos são mecanismos importantes para registro e disseminação de conhecimento e comunicação entre seres humanos. Organizações de software contam com esse mecanismo para a realização de projetos. Essas organizações, quando maduras, definem uma série de modelos de documento de software para apoiar o processo de documentação. Adicionalmente, as mesmas contam com processos e mecanismos para registrar o histórico evolutivo dos documentos envolvidos em um projeto. A quantidade de documentos gerados durante o ciclo de vida de um projeto de software pode ser consideravelmente grande. Apesar dos sistemas de controle de versão facilitarem o controle da evolução dos documentos, os mesmos não são capazes de apoiar a integração e a visualização objetiva de suas informações. Somado a isso, documentos são normalmente tratados como um mero conjunto de caracteres com estilos de formatação voltados para renderização em ferramentas de edição de texto (em inglês, document authoring tool). Neste contexto, a adição de metadados baseados em ontologias de domínio apoia o desenvolvimento de documentos semânticos que podem ser utilizados para contornar esse cenário. O processo de anotação semântica de documentos, quando feito de forma manual, é enfadonho e suscetível a erros. O uso de modelos de documento com anotações semânticas é uma opção viável para a automatização parcial desse processo. Assim, a união de mecanismos de integração contidos em sistemas de controle de versão e modelos de documento de software semanticamente anotados é um meio potencial de apoiar a integração de informações e, por conseguinte, a execução de projetos de software. Esta dissertação trata da utilização de modelos de documento de software anotados semanticamente e mecanismos de controle de versão para registrar a evolução do conteúdo semântico existente em documentos gerados e para prover serviços de integração e visibilidade dos dados relativos aos documentos. Para tal, uma Plataforma para Gerenciamento de Documentos Semânticos é definida
Documents are important mechanisms to register and disseminate knowledge and allow communication between human beings. Software Organizations use this mechanism to conduct projects. When these organizations reach a certain level of maturity they tend to use software document models in order to support the documentation process. Additionally, organizations count on processes and mechanisms to track the evolution of documents involved in a project. The amount of documents produced during a software project lifecycle can be considerably large. Despite the fact that version control systems support document centralization they are not capable of support information integration and visibility. Summing up, documents are treated as a set of characters tied with formatting styles because their primary goal is to be well rendered on a document authoring tool. In this context, adding domain ontology based metadata can help developing semantic documents, which, in turn, can help overcoming this scenario. Manual Semantic Annotation is notably dull and error prone. Combining document models semantic annotation is a viable option in order to achieve the annotation process automatization. Thus, uniting integration mechanisms provided by version control systems and software document models semantically annotated is a potential way of supporting information integration and, therefore, executing software projects. This work treats the use of software document models annotated semantically and version control mechanisms to track and register the evolution of a semantic document content (instantiated from a semantic model) and the provision of data visibility and integration services. In this sense, a Platform for Managing Semantic Documents is defined

Повний текст джерела«What do I need to know about something to know it ?». It is no wonder that such a general, hard to grasp and riddle-like question remained the exclusive domain of a single discipline for centuries : Philosophy. In this context, the distinction of the primitive components of reality – the so called "world’s furniture" – and their relations is called an Ontology. This book investigates the emergence of similar questions in two different though related fields, namely : Artificial Intelligence and Knowledge Engineering. We show here that the way these disciplines apply an ontological methodology to either cognition or knowledge representation is not a mere analogy but raises a bunch of relevant questions and challenges from both an applied and a speculative point of view. More specifically, we suggest that some of the technical answers to the issues addressed by Big Data invite us to revisit many traditional philosophical positions concerning the role of language or common sense reasoning in the thought or the existence of mind-independent structure in reality

Повний текст джерелаThe increasing of competition, expanding markets and advanced technology create shorten lifecycle and the development process to improve product performance in terms of time, cost and quality. These shorten products lifecycle have led to increase volumes of waste generation and consequence impact to environment. EU directives have been introduced, such as Waste Electrical and Electronic Equipment (WEEE), Restriction of the use of certain Hazardous Substances in electrical and electronic equipment (RoHS) and guidelines for the treatment of waste batteries (Battery), these directives are used to handle the hazardous substances which are harmful to human health and the environment.These regulations and standards have been put in place to force companies take their responsibilities on managing their products when reach to the end of life. Some companies have found that the returned product can be recycled or reused as an additional source of income (material recycling, or reuse of components after disassembly) in the manufacturing process.Knowledge related to the environmental performance (in terms of process design, production, transportation, storage, etc.) should be captured, evaluated and stored in knowledge base in order to share between users in different phases of the product lifecycle.Therefore, this research proposes a Knowledge Management Architecture based on a Multi-Agent System approach. The objective of this work is to propose a system that focuses on the concept of "sustainability” of products lifecycle by establishing the link between agents, who hold knowledge related to the environmental performances, and PLM system. The connection encourages companies considering the environmental impacts in their decision making at every stage of product lifecycle
