Abstract:

Information retrieval (IR) is an important part of many tasks performed by people when they use computers. However, most IR research and theory isolates the IR component from the tasks performed by users. This is done by expressing user needs as a query performed on a database. In contrast this dissertation investigates the design and evaluation of information retrieval systems where the information retrieval mechanisms remain embedded in the user tasks. While there are a many different types of user tasks performed with computers we can specify common requirements for the IR needed in most tasks. There are both user interface and machine processing requirements. For user interfaces it is desirable if users interact directly with information databases, keep control of the interaction and are able to perform IR in a timely manner. Machine processing has to be within the capabilities of machines yet must fit with human perceptions and has to be efficient in both storage and computation. Given the overall requirements, the dissertation gives a particular implementation for how to embed IR in tasks. The implementation uses a vector representation for objects and organises the objects in a near neighbour data structure. Near neighbours are defined within the context of the tasks the users wish to achieve. While the implementation could use many different finding mechanisms, it emphasises a constructive solution building approach with localised browsing in the database. It is shown how the IR implementation fits with the overall task activities of the user. Much of the dissertation examines how to evaluate embedded IR. Embedded IR requires testing users' task performance in both real experiments and thought experiments. Implementation is tested by finding known objects, by validating the machine representations and their correspondence with human perceptions and by testing the machine performance of the implementation. Finally implications and extensions of the work arc explored by looking at the practicality of the approach, other methods of investigation and the possibility of building dynamic learning systems that improve with use.

Abstract:

Web browsing has become an integral part of our lives, and we use browsers to perform many important activities almost everyday and everywhere. However, due to the vulnerabilities in Web browsers and Web applications and also due to Web users' lack of security knowledge, browser-based attacks are rampant over the Internet and have caused substantial damage to both Web users and service providers. Enhancing Web browsing security is therefore of great need and importance.;This dissertation concentrates on enhancing the Web browsing security through exploring and experimenting with new approaches and software systems. Specifically, we have systematically studied four challenging Web browsing security problems: HTTP cookie management, phishing, insecure JavaScript practices, and browsing on untrusted public computers. We have proposed new approaches to address these problems, and built unique systems to validate our approaches.;To manage HTTP cookies, we have proposed an approach to automatically validate the usefulness of HTTP cookies at the client-side on behalf of users. By automatically removing useless cookies, our approach helps a user to strike an appropriate balance between maximizing usability and minimizing security risks. to protect against phishing attacks, we have proposed an approach to transparently feed a relatively large number of bogus credentials into a suspected phishing site. Using those bogus credentials, our approach conceals victims' real credentials and enables a legitimate website to identify stolen credentials in a timely manner. to identify insecure JavaScript practices, we have proposed an execution-based measurement approach and performed a large-scale measurement study. Our work sheds light on the insecure JavaScript practices and especially reveals the severity and nature of insecure JavaScript inclusion and dynamic generation practices on the Web. to achieve secure and convenient Web browsing on untrusted public computers, we have proposed a simple approach that enables an extended browser on a mobile device and a regular browser on a public computer to collaboratively support a Web session. A user can securely perform sensitive interactions on the mobile device and conveniently perform other browsing interactions on the public computer.

Abstract:

In this thesis, we examine algorithms for content selection and information presentation that enable browsing as an information-seeking strategy. Our hypothesis is that users who wish to explore the contents of a particular domain might not be satisfied with traditional spoken dialogue systems, in which focal information is not described until a small number of the records comprising the domain are identified through a constraint-elicitation process. Specifically, we hypothesized that users would prefer responses in the form of incremental summaries of the focal information.

Abstract:

We begin by studying field-theory amplitude relations such as the Kleiss-Kuijf, Bern-Carrasco-Johansson, Kawai-Lewellen-Tye and the double copy construction, which are important ingredients in this thesis. Going beyond the field-theory limit we study how the gauge-sector of the heterotic string relates to type I amplitudes through the single valued projection of multiple zeta values. At low energy and for a U(1) gauge group (a single brane) the type I amplitudes are generated by the Born-Infeld action, whereas the corresponding heterotic amplitudes vanish in this limit. As a simple exercise we study Yang-Mills theory deformed by a $F^4$ operator, which is the first correction induced by the Born-Infeld action. This exercise is then generalized by considering the four- and six-point amplitudes in Tseytlin's proposal for a non-Abelian Born-Infeld action. Comparing these amplitudes with those found in type I and heterotic string theory we attempt to gain more insight about the non-Abelian Born-Infeld action.

Abstract:

With the wide-spread adoption of hypermedia systems and the World Wide Web (WWW) in particular, these systems have evolved from simple systems with only textual content to those that incorporate a large content base, which consists of a wide variety of document types. Also, with the increase in the number of users, there has grown a need for these systems to be accessible to a wider range of users. Consequently, the growth of the systems along with the number and variety of users require new presentation and navigation mechanisms for a wider audience. One of the new presentation methods is the audio-only presentation of hypertext content and this research proposes a novel solution to this problem for complex and dynamic systems. The hypothesis is that the proposed Audio Browser is an efficient tool for presenting hypertext in audio format, which will prove to be useful for several applications including browsers for visually-impaired and remote users. The Audio Browser provides audio-only browsing of contents in a Petri-based hypertext system called Context-Aware Trellis (caT). It uses a combination of synthesized speech and pre-recorded speech to allow its user to listen to contents of documents, follow links, and get information about the navigation process. It also has mechanisms for navigating within documents in order to allow users to view contents more quickly.

Abstract:

The use of the internet has become very important in our daily life. At present, web pages are mostly shown as two-dimensional content. Three-dimensional web pages are rarely seen on the Internet. In this thesis, the main task is to develop an interactive 3D (three-dimensional) web prototype for the company Interactive TV Arena. This three-dimensional web prototype will be integrated to the OSIA (open server interface architecture) project which is a project in Interactive TV Arena. In order to implement the prototype, three main tasks were addressed: The first is creating the framework of the prototype with XML files. Secondly, a parser framework was built with JavaScript classes. The third task is to render the prototype with WebGL in real time. The prototype can be used to develop the 3D web pages in modern browsers. This thesis has completed most of the aforementioned tasks and the result of it can be used to develop some simple 3D web pages.

Abstract:

This research project is focused on understanding the current needs of blind users in the context of browsing on the internet. The research methods used have an inclusive design approach. The outcome was intended for both for the blind and normally sighted. At the broadest level, this project is about reducing cognitive effort in human to computer interaction. At the next level it is about browsing the internet. Everyone using a computer and surfing the web at some point goes through the mental task of comparing between alternative choices. Examining today’s obstacles for the blind, what aspects of the experience could we improve? Could we design a better cognitive browsing experience for all users focusing on nonvisual aspects of the user experience? What would it look like, how would it behave and what characteristics would it carry? The Semantic Scroller is a concept that could be implemented today but actually presupposes the use of some new HTML specifications specifically the adoption of “open” semantic tags. Unlike existing semantic tags like <nav> and <article> which are too context specific, an open framework would enable coders include contextual semantic descriptions where ever necessary.

Abstract:

The exploration of large information spaces has remained a challenging task even though the proliferation of database management systems and the state-of-the art retrieval algorithms is becoming pervasive. Signi cant research attention in the multimedia domain is focused on nding automatic algorithms for organising digital image collections into meaningful structures and providing high-semantic image indices. On the other hand, utilisation of graphical and interactive methods from information visualisation domain, provide promising direction for creating e cient user-oriented systems for image management. Methods such as exploratory browsing and query, as well as intuitive visual overviews of image collection, can assist the users in nding patterns and developing the understanding of structures and content in complex image data-sets. The focus of the thesis is combining the features of automatic data processing algorithms with information visualisation. The rst part of this thesis focuses on the layout method for displaying the collection of images indexed by low-level visual descriptors. The proposed solution generates graphical overview of the data-set as a combination of similarity based visualisation and random layout approach. Second part of the thesis deals with problem of visualisation and exploration for hierarchical organisation of images. Due to the absence of the semantic information, images are considered the only source of high-level information. The content preview and display of hierarchical structure are combined in order to support image retrieval. In addition to this, novel exploration and navigation methods are proposed to enable the user to nd the way through database structure and retrieve the content. On the other hand, semantic information is available in cases where automatic or semi-automatic image classi ers are employed. The automatic annotation of image items provides what is referred to as higher-level information. This type of information is a cornerstone of multi-concept visualisation framework which is developed as a third part of this thesis. This solution enables dynamic generation of user-queries by combining semantic concepts, supported by content overview and information ltering. Comparative analysis and user tests, performed for the evaluation of the proposed solutions, focus on the ways information visualisation a ects the image content exploration and retrieval; how e cient and comfortable are the users when using di erent interaction methods and the ways users seek for information through di erent types of database organisation.

Abstract:

Mestrado em Engenharia de Computadores e Telemática
This Master dissertation has the aim of study, and further develop, a tool that allows to gather Quality of Experience metrics, in the Web browsing context, in order to perceive, as close to reality as possible, the experience that real users would have during the navigation in webpages. The gathering of Quality of Experience and Service metrics are essential for telecom operators, in order to diagnose the quality of services and, consequently, perceive the level of satisfaction of its clients. In this context, the solution was an application that acts independently and performs tests, that allow to infer the experience that a real user would face during the access to a webpage, through a real browser. The solution is able to: extract time metrics, information related with the Web navigation, the status of the webpage and its resources. Furthermore, it allows to con gure simple or more complex interaction test scenarios with the webpage, take screen captures during the test execution and even download all the les belonging to the webpage that were loaded. The solution was tested in order to evaluate its performance and returned values (metrics) reliability, comparing with a real navigation values.
Esta dissertação de Mestrado tem por objectivo o estudo e o desenvolvimento de uma ferramenta de aferição de métricas de Qualidade de Experiência, no contexto da navegação Web, de modo a percepcionar, da forma mais real possível, a experiência dos utilizadores comuns na navegação em paginas Web arbitrarias. A obtenção de métricas que permitam determinar a Qualidade de Experiência e de Serviço são uma ferramenta essencial para as operadores de telecomunicações, de forma a diagnosticar o nível de qualidade dos serviços prestados e, consequentemente, perceber o grau de satisfação dos clientes. Neste contexto, a solução desenvolvida foi uma ferramenta que actua de forma independente e efectua testes que permitem aferir a experiência a que um utilizador normal estaria sujeito face a navegação numa pagina Web, num browser real. Assim, a aplicação desenvolvida e capaz de: extrair intervalos temporais para inferir a qualidade da experiência, informações acerca da navegação e do estado da pagina Web, bem como dos seus componentes. Para alem disso, permite configurar cenários de interacção simples ou complexos com a pagina, tirar capturas de ecra em vários momentos durante o correr do programa e ainda, permite descarregar todos os ficheiros que compõem a pagina Web, que foram carregados. Esta solução foi sujeita a testes de averiguação do desempenho e da contabilidade dos valores devolvidos (métricas) pela mesma, quando comparados com uma navegação real.

Abstract:

Artificial Intelligence Lab, Department of MIS, University of Arizona
With the growth of hypertext and multimedia applications that support and encourage browsing it is time to take a penetrating look at browsing behavior. Several dimensions of browsing are examined, to find out: first, what is browsing and what cognitive processes are associated with it; second, is there a browsing strategy, and if so, are there any differences between how subject-area experts and novices browse; and finally, how can this knowledge be applied to improve the design of hypertext systems. Two groups of students, subject-area experts and novices, were studied while browsing a Macintosh H y p e r c a r d application on the subject of The Vietnam War. A protocol analysis technique was used to gather and analyze data. Components of the GOMS model were used to describe the goals, operators, methods, and selection rules observed. Three browsing strategies were identified: 1) search-oriented browse, scanning and reviewing information relevant to a fixed task, 2) reviewbrowse, scanning and reviewing interesting information in the presence of transient browse goals that represent changing tasks, and 3) scan-browse, scanning for interesting information (without review). Most subjects primarily used review-browse interspersed with search-oriented browse. Within this strategy, comparisons between subject-area experts and novices revealed differences in tactics: experts browsed in more depth, seldom used referential links, selected different kinds of topics, and viewed information differently than did novices. Based on these findings, suggestions are made to hypertext developers.

Abstract:

The amount of non-English information has proliferated rapidly in recent years. The broad diversity of the multilingual content presents a substantial research challenge in the field of knowledge discovery and information retrieval. Therefore there is an increased interest in the development of multilingual systems to support information sharing across languages. The goal of this dissertation is to study how different techniques and algorithms could help in multilingual Internet searching and browsing through a series of case studies.A system development research process was adopted as the methodology in this dissertation. In the first part of the dissertation, I discuss the development of CMedPort, a Chinese medical portal to serve the information seeking needs of Chinese users. A systematic evaluation has been conducted to study the effectiveness and efficiency of CMedPort in assisting human analysis. My experimental results show that CMedPort achieved significant improvement in searching and browsing performance compared to three benchmark regional search engines.The second and third case studies aim to investigate effective and efficient techniques and algorithms that facilitate multilingual Web retrieval. An English-Chinese multilingual Web retrieval system in the business IT domain was developed and evaluated. It was then extended into five languages: English, Chinese, Japanese, German and Spanish. A dictionary-based approach was adopted in query translation. Corpus-based co-occurrence analysis, relevance feedback, and phrasal translation algorithms were used for disambiguation purposes. Evaluation results showed that the system's phrasal translation and co-occurrence disambiguation led to great improvement in performance. The last part of this dissertation studies proper name translation problem. Proper names are often out-of-vocabulary terms and are critical to multilingual Web retrieval. This study proposes a combined Hidden Markov Model and Web mining model to automatically generate proper name translations. The approach was evaluated on two language pairs: English-Arabic and English Chinese. My results are encouraging and show promise for using transliteration techniques to improve multilingual Web retrieval.This dissertation has two main contributions. Firstly, it demonstrated how information retrieval, Web mining and artificial intelligence techniques can be used in a multilingual Web-based context. Secondly, it provided a set of tools that can facilitate users in their multilingual Web searching and browsing activities.

Abstract:

Les données dites multimédia (images, vidéos) se distinguent des données classique par une densité variable d'information et l'impossibilité de normaliser ces données. Du fait de ces particularités, de nouvelles techniques d'indexation et de recherche d'information ont du être etudiées. Il y a principalement deux problèmes a résoudre pour la recherche d'information dans les collections multimédia (ou les bases de données multimédia) : (1) la représentation des données et (2) le processus de recherche du point de vue de l'utilisateur. Dans le cas des bases de données, l'indexation est fortement liée a ces deux problèmes. Dans le cas particulier des images, on distingue trois grandes classes: – la recherche par requêtes formelles, héritée des bases de données classiques ; – la recherche avec boucle de retour, où l'utilisateur fait partie intégrante du processus de recherche ; – la navigation où les images sont organisées en une structure preparée à l'avance, utilisée comme index et comme structure de recherche. C'est sur cette troisième approche que nos travaux se sont portés ; nous nous sommes en effet interessés au treillis de Galois, une structure de graphe permettant d'organiser les éléments d'une relation binaire. Une telle structure de navigation a plusieurs avantages sur une approche classique basée sur des requêtes : en particulier, elle permet d'affranchir l'utilisateur d'une phase de rédaction de requête.

Abstract:

The Web is increasingly being accessed by portable, multi-touch wireless devices. Despite the popularity of platform-specific (native) mobile apps, a recent study of smartphone usage shows that more people (81%) browse the Web than use native apps (68%) on their phone. Moreover, many popular native apps such as BBC depend on browser-like components (e.g., Webview) for their functionality. The popularity and prevalence of web browsers on modern mobile phones warrants characterizing existing and emerging threats to mobile web browsing, and building solutions for the same. Although a range of studies have focused on the security of native apps on mobile devices, efforts in characterizing the security of web transactions originating at mobile browsers are limited. This dissertation presents three main contributions: First, we show that porting browsers to mobile platforms leads to new vulnerabilities previously not observed in desktop browsers. The solutions to these vulnerabilities require careful balancing between usability and security and might not always be equivalent to those in desktop browsers. Second, we empirically demonstrate that the combination of reduced screen space and an independent selection of security indicators not only make it difficult for experts to determine the security standing of mobile browsers, but actually make mobile browsing more dangerous for average users as they provide a false sense of security. Finally, we experimentally demonstrate the need for mobile specific techniques to detect malicious webpages. We then design and implement kAYO, the first mobile specific static tool to detect malicious webpages in real-time.

Abstract:

Um in einer Menge von Daten nach bestimmten Informationen suchen und filtern zu können, verwenden Suchmaschinen und Datenbanksysteme Queries (Suchanfragen). Diese Queries sind häufig durch eine eigene Sprache definiert, welche die Bildung von komplexen Ausdrücken erlaubt. Die Systeme antworten auf die Suchanfrage in Form einer Ergebnismenge. Komplexe Suchanfragen ermöglichen dabei das Auffinden von präzisen Ergebnissen. Faceted Browsing ist ein Benutzerschnittstellen-Paradigma zum Suchen und Filtern von Daten. Dabei können Suchanfragen visuell erstellt und sukzessiv verfeinert werden, ohne die spezielle Anfragesprache kennen zu müssen. Die einfache und intuitive Benutzbarkeit der Oberfläche bildet das Erfolgsrezept, sodass Faceted Browsing in vielen Anwendungen, wie beispielsweise auch in Online-Shops, zum Einsatz kommt. Bisher sind die Systeme überwiegend so konzipiert, dass Queries, welche aus Konjunktionen von Disjunktionen bestehen, gebildet werden können. Es stellt sich nun die Frage, ob auch komplexere Suchanfragen mittels Faceted Browsing erstellt werden können und welche Veränderungen der Oberfläche dafür notwendig sind. Reichen die Veränderungen dabei so weit, dass zu Gunsten der Komplexität der Suchanfrage auf die Einfachheit der Oberfläche verzichtet werden muss oder existieren Möglichkeiten, komplexere Queries zu bilden und dabei die Einfachheit der Oberfläche zu bewahren? Ziel der Arbeit ist es, zu ermitteln, welche Komplexität die Suchanfragen, die mittels Faceted Browsing gebildet werden, aufweisen können, ohne dabei die einfache Benutzbarkeit der Facettenbrowseroberfläche zu verlieren. Dazu wird die bisherige Mächtigkeit von Facettenbrowseroberflächen hinsichtlich der Querybildung analysiert. Weiterhin werden komplexere Suchanfragen auf ihre Umsetzbarkeit mit Hilfe des Faceted Browsing untersucht. Es wird betrachtet, auf welche Weise sich bisherige Facettenbrowseroberflächen verändern müssen, um die visuelle Erstellung solcher Suchanfragen zu ermöglichen. Durch die prototypische Erweiterung eines bestehenden Facettenbrowsers um notwendige Oberflächenelemente soll die Möglichkeit bestehen, komplexere Suchanfragen, als bisher mittels Faceted Browsing möglich, zu bilden.

Abstract:

Web browsing has been one of the most popular activities on the internet. The increasing importance of the Web in everyday life calls for device-independent access to existing web sites. Although, there is full Web access available on mobile phones the user experience is often poor when compared to the Web user experience on Personal Computer (PC). Therfore, it is important for the Internet service provider to find the indications of user dissatisfaction from the network. While using the mobile Web, user can normally abort the transfer by pressing the stop or reset buttons in the browsers, leaving the page being downloaded by following a bookmark or can close the connection. Such events can be observed through the TCP reset (RST) flag from traffic on network level. In this thesis we have investigated the possible causes of TCP RST flags mobile Web session is interrupted. We further analyze up to what extent we can rely on TCP RST flags for being an indication of user dissatisfaction in mobile web browsing. Therefore, an experiment testbed is developed to capture the TCP packet traces during controlled active tests. Results are gathered using mobile devices with four popular mobile operating systems (OS). The trace files captured are analyzed using perl script to dicern the flow and focusing on the TCP RST flag during the flow. Further, TSTAT tool is used to validate our trace files.

Abstract:

In our daily lives, we have conversations with others in many different modalities like meetings, emails, chats, blogs etc. At the advent of the Web, the volume and the complexity of the conversational data generated through our day to day communication have increased many folds. A way to deal with this overwhelming amount of interactional information is to use automatic summarization for quick access. Although Machine Learning approaches can be used to generate automatic summaries, extractive or abstractive, they still have not reached the level of quality of human generated summaries. We introduce here a visual interface that takes advantage of human cognition and perception abilities in conjunction with automatically extracted knowledge concepts for the conversation to analyze it and to automatically generate a summary for it. Our interface provides the user an overview of the conversation's content and a way to quickly explore it. It aids to identify informative sentences as potential components of the summary based on visual cues. Our objective is to provide the user more control over choosing the topics she wants to appear in the concise resultant overview generated through interactive exploration, thus generating a focused summary. We use an ontology containing nodes for speakers, dialogue acts (DA), and a list of entities referred to in the conversation to provide entry points to the conversation. These concepts in the ontology are derived using classifiers based on generic features making it possible to use the interface to explore any mode of conversational data. In this thesis, we have designed an interface based on the principles of Natural Language Processing, Human Computer Interaction, and Information Visualization that can be used to browse a human conversation using the mapping of sentences to those ontology concepts and can be used to generate a brief and focused summary for the conversation. We have evaluated our interface in a formal user study and have found that our interface facilitates widely varying approaches adopted by people trying to analyze a conversation.

Abstract:

The research presented in this thesis explores the use of videos embedded in panoramic imagery to transmit spatial and temporal information describing remote environments and their dynamics. Virtual environments (VEs) through which users can explore remote locations are rapidly emerging as a popular medium of presence and remote collaboration. However, capturing visual representation of locations to be used in VEs is usually a tedious process that requires either manual modelling of environments or the employment of specific hardware. Capturing environment dynamics is not straightforward either, and it is usually performed through specific tracking hardware. Similarly, browsing large unstructured video-collections with available tools is difficult, as the abundance of spatial and temporal information makes them hard to comprehend. At the same time, on a spectrum between 3D VEs and 2D images, panoramas lie in between, as they offer the same 2D images accessibility while preserving 3D virtual environments surrounding representation. For this reason, panoramas are an attractive basis for videoconferencing and browsing tools as they can relate several videos temporally and spatially. This research explores methods to acquire, fuse, render and stream data coming from heterogeneous cameras, with the help of panoramic imagery. Three distinct but interrelated questions are addressed. First, the thesis considers how spatially localised video can be used to increase the spatial information transmitted during video mediated communication, and if this improves quality of communication. Second, the research asks whether videos in panoramic context can be used to convey spatial and temporal information of a remote place and the dynamics within, and if this improves users' performance in tasks that require spatio-temporal thinking. Finally, the thesis considers whether there is an impact of display type on reasoning about events within videos in panoramic context. These research questions were investigated over three experiments, covering scenarios common to computer-supported cooperative work and video browsing. To support the investigation, two distinct video+context systems were developed. The first telecommunication experiment compared our videos in context interface with fully-panoramic video and conventional webcam video conferencing in an object placement scenario. The second experiment investigated the impact of videos in panoramic context on quality of spatio-temporal thinking during localization tasks. To support the experiment, a novel interface to video-collection in panoramic context was developed and compared with common video-browsing tools. The final experimental study investigated the impact of display type on reasoning about events. The study explored three adaptations of our video-collection interface to three display types. The overall conclusion is that videos in panoramic context offer a valid solution to spatio-temporal exploration of remote locations. Our approach presents a richer visual representation in terms of space and time than standard tools, showing that providing panoramic contexts to video collections makes spatio-temporal tasks easier. To this end, videos in context are suitable alternative to more difficult, and often expensive solutions. These findings are beneficial to many applications, including teleconferencing, virtual tourism and remote assistance.

Abstract:

This research is concerned with the retrieval of visual or pictorial information from videodisc databases. Videodisc technology has made automated storage and retrieval of high quality visual information possible. A problem is that traditional keyword or text access to pictorial information may be inappropriate if the type of information sought cannot be readily described in words. An answer may be to encourage visual searching or browsing. The challenge lies in creating flexible retrieval systems which will both maximise search efficiency and accommodate the individual user. An experimental retrieval environment was developed to examine visual information search strategies. This system allowed for three search types: keyword search, specific browsing, and scanning. Over two experiments visual information search and browsing strategies were identified and characterised: seeking, focused exploring, open exploring, and wandering. In addition, five factors which influence visual information search strategies were identified: the nature of the information itself, database structure, the task or information need, the user, and the interface. This research combines elements of information retrieval and human factors to point to ways in which visual information retrieval systems can be developed which will meet the needs of their users. System design must take account of individual search behaviour and utilise knowledge of the factors which influence user interaction with the system in the search and retrieval process.

Abstract:

This thesis describes the development of a large database of texture stimuli, the production of a similarity matrix re ecting human judgements of similarity about the database, and the development of three browsing models that exploit structure in the perceptual information for navigation. Rigorous psychophysical comparison experiments are carried out and the SOM (Self Organising Map) found to be the fastest of the three browsing models under examination. We investigate scalable methods of augmenting a similarity matrix using the SOM browsing environment to introduce previously unknown textures. Further psychophysical experiments reveal our method produces a data organisation that is as fast to navigate as that derived from the perceptual grouping experiments.

Abstract:

Image sizes have increased exponentially in recent years. The resulting high-resolution images are often viewed via remote image browsing. Zooming and panning are desirable features in this context, which result in disparate spatial regions of an image being displayed at a variety of ( spatial) resolutions. When an image is displayed at a reduced resolution, the quantization step sizes needed for visually lossless quality generally increase. This paper investigates the quantization step sizes needed for visually lossless display as a function of resolution, and proposes a method that effectively incorporates the resulting ( multiple) quantization step sizes into a single JPEG 2000 codestream. This codestream is JPEG 2000 Part 1 compliant and allows for visually lossless decoding at all resolutions natively supported by the wavelet transform as well as arbitrary intermediate resolutions, using only a fraction of the full-resolution codestream. When images are browsed remotely using the JPEG 2000 Interactive Protocol ( JPIP), the required bandwidth is significantly reduced, as demonstrated by extensive experimental results.

Abstract:

The browsing damage by moose ( Alces alces) is an actual and real problem that is happening in Swedish boreal forests nowadays. The browsing can be done for different types of cervids like roe deer, moose and goats, but we will focus on the browsing damage by moose because it is the main browser on pine stand and is causing the biggest problem in Sweden due to the high moose population that currently exist. The moose is the biggest species in the deer family and one of the most spread species in Sweden. We performed our study in fifteen plantation areas of Scots pines (Pinus sylvestris) in Gävleborg county, Sweden. Some of these plantations have a natural origin, whereas others have been created by human. The increase of browsing damage by moose have several consequences including effects on the ecological community and huge economic consequences, as the forest companies are losing, billions of Swedish crowns per year because of the browsing damage on the pine trees. The aim of this study was to investigate how the browsing damage by moose on Scots Pines varies depending on the density of the different deciduous tree species. Some of the most important results that I obtained were a negative relation between the number of deciduous trees and the browsing damage in Scots pine, the positive relation between the number of damaged deciduous trees very close to the Scots pine studied and the browsing damage in Scots pine and finally, the positive relation between the old browsing damage and new browsing damage in Scot pine. In general, I can conclude that when the number of deciduous trees increases in an area, the browsing damage in Scot pine decreases.

In the recent literature, we have seen the expansion of information retrieval techniques to include a variety of different collections of information. Collections can have certain characteristics that can lead to different results for the various classification techniques. In addition, the ways and reasons that users explore each collection can affect the success of the information retrieval technique. The focus of this research was to extend the application of our statistical and neural network techniques to the domain of geological science information retrieval. For this study, a test bed of 22,636 geoscience abstracts was obtained through the NSF/DARPA/NASA funded Alexandria Digital Library Initiative project at the University of California at Santa Barbara. This collection was analyzed using algorithms previously developed by our research group: concept space algorithm for searching and a Kohonen self-organizing map (SOM) algorithm for browsing. Included in this paper are discussions of our techniques, user evaluations and lessons learned.

Abstract:

Artificial Intelligence Lab, Department of MIS, University of Arizona
Information overload is a critical problem in World Wide Web. Category map developed based on Kohonenâ s selforganizing map (SOM) has been proven to be a promising browsing tool for the Web. The SOM algorithm automatically categorizes a large Internet information space into manageable sub-spaces. It compresses and transforms a complex information space into a two-dimensional graphical representation. Such graphical representation provides a user-friendly interface for users to explore the automatically generated mental model. However, as the amount of information increases, it is expected to increase the size of the category map accordingly in order to accommodate the important concepts in the information space. It results in increasing of visual load of the category map. Large pool of information is packed closely together on a limited size of displaying window, where local details are difficult to be clearly seen. In this paper, we propose the fisheye views and fractal views to support the visualization of category map. Fisheye views are developed based on the distortion approach while fractal views are developed based on the information reduction approach. The purpose of fisheye views are to enlarge the regions of interest and diminish the regions that are further away while maintaining the global structure. On the other hand, fractal views are an approximation mechanism to abstract complex objects and control the amount of information to be displayed. We have developed a prototype system and conducted a user evaluation to investigate the performance of fisheye views and fractal views. The results show that both fisheye views and fractal views significantly increase the effectiveness of visualizing category map. In addition, fractal views are significantly better than fisheye views but the combination of fractal views and fisheye views do not increase the performance compared to each individual technique.
