A World-Wide Web (WWW) tem se desenvolvido enormemente, facilitando o compartilhamento de informações. Muito rapidamente as aplicações do seu potencial educacional se tornaram aparentes, especialmente para a Educação à Distância (ED). Neste sentido, a WWW possui um maior apelo, devido a sua capacidade de exibição de documentos multimídia, capacidade de hipertexto/hipermídia e sua arquitetura cliente-servidor, possibilitando a interação entre aluno e professor em ED. Este trabalho apresenta o desenvolvimento da ferramenta Web Course, desenvolvida no IFSC-USP, que visa facilitar a criação de provas na WWW. A ferramenta também faz a correção automática das provas. Web Course é uma ferramenta baseada em templates, usando formulários HTML criados por programas CGI que são preenchidos pelos instrutores para a criação de provas.The World-Wide Web (WWW) has been developed largely to facilitate sharing of information. Very quickly, potential educational applications of this technology became apparent, especially for Distance Education (DE). In this regard, WWW has more appeal, because of its capability to exhibit multimedia documents, its hypertext/hypermedia capability and its client-server architecture, making possible the interaction between students and instructors. This work presents the development of Web Course, a tool developed at IFSC-USP that facilitates the creation of tests on the WWW, providing also the automatic correction of them. Web Course is template based, using HTML forms created by CGI files that instructors simply fill in to create tests.

O presente trabalho consistiu na proposta, desenvolvimento e teste de um ambiente computacional hierárquico que vise facilitar a criação, organização e gerenciamento de cursos para serem disponibilizados via Internet, inserido nos projetos de Educação a Distância conduzidos pelo CDCC (Centro de Divulgação Científica e Cultural da USP- São Carlos), tendo como objetivo inicial o treinamento e reciclagem de professores da rede pública, nas disciplinas de física e ciências. O ambiente possui um sistema especialista para o tratamento das dúvidas dos usuários, o Sistema Gerenciador de Dúvidas Online (SGDO) que se tornou uma ferramenta autônoma e hoje faz parte do Plantão de Dúvidas Online do CDCC/USP. O SGDO utiliza o conceito de Education Intelligence, através do uso de data mining, possibilitando ao instrutor selecionar dados, analisar informações, identificar tendência e tomar decisões no decorrer de um curso a distância. A ferramenta WebCourse é um ambiente hierárquico baseado na Web consistindo de quatro módulos: WebCourse Instrutor, WebCourse Monitor, WebCourse Aluno e WebCourse Administrador. Cada módulo possui ferramentas específicas, desenvolvidas para as necessidades dos agentes participantes do ambiente (instrutores, monitores, alunos e administradores). O ambiente é dito hierárquico porque algumas de suas ferramentas somente podem ser usadas por certos módulos. Cada módulo está altamente conectado aos outros e todas as ferramentas são baseadas em templates HTML, usando a linguagem script Lite, do banco de dados mSQL, para a geração de arquivos HTML dinâmicos. Todo o sistema é gerenciado através de um banco de dados mSQL, localizado num servidor web, onde os dados são armazenados e recuperados sob demanda.The present work consisted on the proposal, development and test of a hierarchical computational environment to facilitate the creation, organization and management of courses to be available over the Internet, inserted on the projects of Distance Education conducted by CDCC (Center for Scientifical and Cultural Dissemination at the University of São Paulo at São Carlos). Its initial objective was training public school teachers of Physics and Sciences. The environment has a specialist system for the treatment of online doubts called Online Doubt Managing System (ODMS), which became an autonomous tool inside the Online Doubt Helping Center at CDCC/USP. ODMS utilizes the concept of Education Intelligence through the use of data mining, making it possible for instructors to select data, analyze informations, identify trends and take decisions during a course carried via Web. WebCourse is a hierarchical web-based tool for the creation and management of web-based courses which consists of four modules: WebCourse Instrutor (Instructor Module), WebCourse Monitor (Teacher Assistant Module), WebCourse Aluno (Student Module) and WebCourse Administrador (Administrator Module). Every module has a set of specific tools, developed to meet the necessities of the environment\'s participant agents (instructors, teacher assistants, students and administrators). The tool is said to be hierarchical since some of its tools can only be used by certain modules. Each module is highly connected to the others and every tool is template-based, using the mSQL database\'s Lite scripting facility in order to generate HTML files on-the-fly. All the system is managed through a mSQL database, located on a web server, where data is stored and recovered on demand.

Full textAbstract:
In recent times, there has been a strong push for higher education institutions to offer more online courses to cater for students who otherwise would be denied university education. While this may benefit the many distance education students, the take-up rate of totally online education by current on-campus students remains uncertain. At the same time, many lecturers have started to design and develop online teaching material for their courses; many do so without the support of their employer - the university that they work in. The purpose of this study is two-fold. Firstly, to gain an insight into how on-campus students perceive online learning and to examine their readiness and willingness to make the shift from conventional classroom learning to online learning with no face-to-face contact. Secondly, to gain an insight into how lecturers approach online teaching; so as to better understand the problems they face when switching to a teaching mode that is quite different from the classroom teaching they are familiar with. The outcomes of this study will provide us with a better understanding of how lecturers and on-campus students perceive online teaching and learning. Understanding students' level of readiness to take part in online learning and their willingness to switch from the conventional classroom to cyberspace will assist universities in making decisions on the future direction of online courses. This is particularly important to those universities that intend to replace conventional classroom teaching with online courses. A better understanding of the problems faced by students and lecturers in online teaching and learning will also enable university administrators to ensure adequate resources are being allocated and the right level of support is provided.Lecturers' experiences in designing and developing online courses also assist in forming guidelines, policies and procedures for others to follow. An exploratory study was carried out on five groups of students and their lecturers to investigate their perceptions of online teaching and learning. Each group of students was enrolled in a specific subject unit when the study was carried out. All of the students were studying on-campus pursuing bachelor or postgraduate qualifications in various disciplines across the university. Students from each group were asked to complete a questionnaire during one of their lecture sessions. Their lecturers were interviewed individually. Both quantitative and qualitative analyses were applied on the collected data. Results of the study found that the majority of the students had sufficient knowledge at using the Internet and were very positive about online teaching and learning. While they would have liked to see more online teaching and learning used in their courses, they would not want it to replace classroom teaching and learning. The lecturers felt that online teaching - the development of online course material and the constant monitoring of students progress, was a time consuming but rewarding task. They would like to see their efforts in taking up such challenges recognised and rewarded by their institution and more resources be provided to assist them in further development in the area.
In conclusion, the outcomes of this study show that if given the choice, not all oncampus students would like to enrol in online courses. The majority of them would still prefer classroom learning supplemented by online learning. Universities should invest in online teaching and learning with more resources allocated to assisting lecturers in online teaching. However, universities contemplating using online courses to replace traditional classroom teaching may find themselves losing their existing on-campus students.

Full textAbstract:
An abundance of information exists on the World Wide Web on almost any subject or topic. How well Web users are able to manage the abundance of information to achieve their goals is expressed through the concept of usability. Researchers (Pitkow and Kehoe, 1997; Shneiderman, 1998; Nielsen, 1995b; Agnew, Wang, Faloutsos and Welch, 1997) report that information on the Web is often disorganized resulting in users experiencing usability difficulties in finding specific information. In addition, studies (Shneiderman, 1998; Mauldin, 1997; Freidman, 1997; Cheah and Koh, 1997; Nielsen, 1990; Smith, 1994; Pitkow and Kehoe, 1997) also reflect that users report related usability difficulties which include, but are not limited to: information abundance and overload; information organization; search engine manipulation and output interpretation; orientation and navigation; and overall design of Web information spaces.
Many researchers (Pitkow and Kehoe, 1997; Shneiderman, 1998; Nielsen, 1995) agree that the Web is becoming an invaluable information resource, however, improvements are necessary to address the issues raised by users who report usability difficulties. Cben and Rada (1996) state that "a synthesis of the empirical findings on hypertext from a single, unifying perspective would help researchers, designers, and users of hypertext systems" (p. 150). The goal of this dissertation was to explore the dimensions of Web usability for users through a synthesis and analysis of current research and address three questions: What are the factors contributing to the problem of Web usability for users? How are researchers and developers currently addressing the problem? What guidelines are available for Web developers that will reduce or eliminate current usability difficulties?
This synthesis of the factors contributing to the usability problems of Web users is intended to help researchers, designers and users of hypertext systems (Chen and Rada, 1996) and reveal suggestions for future research. It is also intended to improve practical application by providing suggestions to improve Web usability by more efficient and effective designs. "The infrastructure, protocols, tools, communities, conventions and activities of the Internet are evolving simultaneously and rapidly" (Kellogg and Richards, 1995, p. 33). These rapid advances are rendering the Web more accessible to greater numbers of diverse user populations who are less technically oriented. Therefore, the value of understanding Web usability issues can only become a critical requirement for Web developers as the user population continues to expand (Kellogg and Richards, 1995).

Full textAbstract:
Tem-se observado que um dos maiores problemas decorrentes da expansão das ferramentas de difusão de informações em ambientes distribuídos, especialmente no modelo WWW-Internet, é a inconsistência das ligações entre os objetos envolvidos (Erro 404 - Arquivo não encontrado). Segundo [WHY 95], uma das mais importantes condições para a qualidade de uma estrutura de hiperdocumento é a manutenção da integridade e atualidade das ligações, sejam estas internas ou externas. Sempre que há alterações na hiperbase, nas estruturas dos documentos que a compõem ou no conteúdo semântico destes, podem surgir inconsistências nas ligações. Estas podem indicar tanto um problema temporário da rede ou servidor quanto um recurso que tenha sido permanentemente movido ou excluído. Acredita-se que o percentual de requisições inválidas cresça de acordo com o tempo, com a inclusão de novos recursos e com a dinamicidade intrínseca das estruturas dos Sistemas de Hiperdocumentos Distribuídos. Faz-se necessária, então, a adoção de modelos de Sistemas de Hiperdocumentos Distribuídos que contemplem o tratamento do problema de inconsistência de ligações desde sua concepção, através de técnicas preventivas ou então o desenvolvimento de ferramentas e técnicas para que a integridade das ligações seja garantida, preferencialmente de modo automático, para os modelos que não a apresentam nativamente Isto posto, este trabalho trata do problema da inconsistência de ligações nos Sistemas de Hiperdocumentos Distribuídos, com ênfase especial no modelo WWW (World-Wide Web) [BER 92]. Para tanto, são apresentados noções e conceitos, histórico, objetivos, estado da arte, arquitetura e requisitos necessários, assim como características específicas dos principais Sistemas de Hiperdocumentos Distribuídos. São tratados, também, os aspectos teóricos referentes aos problemas gerados pela inconsistência de ligações de ordem técnica, psicológica e/ou mercadológica. São apresentadas soluções encontradas na bibliografia para os sistemas implementados, bem como é feita uma classificação destas soluções em nível de preventivas (que não permitem que o problema ocorra) e corretivas (que são utilizadas para solucionar ou minimizar o problema), podendo estas serem, ainda, de funcionamento manual, semiautomático ou automático. A solução proposta, classificada como preventiva semi-automática, baseia-se em entrada de dados via formulário HTML e armazenamento em arquivo do tipo texto, é apresentada através de sua definição, objetivos, funcionamento e do detalhamento do protótipo, através das características de implementação e do ambiente utilizado.We have noticed that one of the biggest problems resulting from the spreading of the information diffusion tools in distributed environments (specially with the WWWInternet model) is the inconsistency of the links between the objects involved (Error 404 - File was not found). According to [WHY 95], one of the most important conditions for the quality of an hyperdocument structure is the maintenance of the integrity of the links, whatever they may be internal or external to the hyperdocument. Whenever there are hyperbase changes, changes on the structures of the papers that compose the hyperbase, or if there are changes on the semantic content of these papers, there may arise inconsistencies with the links. These inconsistencies may indicate a temporary net or server problem, as well as a resource that has been constantly moved or excluded. It’s believed that the percentage of invalid requisites raises in accordance with time, with the introduction of new resources and with the dynamics of the structure of Distributed Hyperdocument Systems. So, it's necessary to adopt models of Distributed Hyperdocument Systems that contemplate a treatment of the problem of the links' inconsistencies since their conception, using preventive techniques or developing tools and techniques to guarantee the integrity of the links, preferably by automatic mode to the models that originally don't have this integrity. Thus, this work is about the problem of links' inconsistency in Distributed Hyperdocument Systems, with special emphasis on the model: WWW (World Wide Web) [BER 92]. For that, basic concepts, history, objectives, the state of the art, architecture and necessary requirements are shown., as well as specific characteristics of the main Distributed Hyperdocument Systems. Also shown are the theoretical aspects concerning the problems produced by the links inconsistency of the technical, psychological and/or market order. Solutions found on the bibliography are shown as well as a classification of these solutions as preventives (that don't permit the problem to occur) and correctives (that are used to solve or minimize the problem) is done. These solutions may still be manual, semi-automatic or automatic. The proposed solution, classified as preventive semiautomatic, is based on data entries using the HTML form and their storage in files in textual form. The definition, objectives, functioning and detail of a prototype are presented.

Full textAbstract:
The World Wide Web (WWW) has become the largest source of Internet traffic, but it was not designed for wireless networks. Documents with large inline images take a long time to fetch over low-bandwidth wireless networks. Radio signal dropouts cause file transfers to abort; users have to restart file transfers from the beginning. Dropouts also prevent access to documents that have not yet been visited by the user. All of these problems create user frustration and limit the utility of the WWW and wireless networks.
In this work, a new Wireless World Wide Web (WWWW) proxy server and protocol were developed that address these problems. A client based on NCSA Mosaic connects to the proxy server using the new protocol, Multiple Hypertext Stream Protocol (MHSP). The proxy prefetches documents to the client, including inline images. The proxy also reduces the resolution of large bitmaps to improve performance over slow links. MHSP provides the ability to resume file transfers when the link has been broken then reestablished.
The WWWW system was tested and evaluated by running script-controlled clients on different emulated network environments. This new system decreased document load time an average of 32 to 37 percent, depending on network configuration.Master of Science

Inom Human- Computer Interaction är användbarhet ett mycket centralt
begrepp. Användbarhet kan i sin tur delas upp i effektivitetsmått och
subjektiv uppfattning. Det råder idag delade meningar i forskarvärlden huruvida det existerar en korrelation mellan dessa två mått. Om denna korrelation existerar kanske vidare forskning visar att någon av de två inte utgör en nödvändig del av användbarhetsbegreppet. Om så är fallet skulle detta kunna leda till enklare och billigare design och utvärderingsprocesser. Den här undersökningen syftar till att undersöka om det existerar en korrelation mellan effektivitet och subjektiv uppfattning på world wide web samt att undersöka om det råder skillnader i denna korrelation mellan experter och noviser. För att undersöka detta har en användbarhetsutvärdering med 31 försöksdeltagare genomförts på en webbsida publicerad på www. Resultatet av undersökningen visar inte på några samband eller korrelationer och resultaten är endast marginellt signifikanta. Inga klara slutsatser kan därför dras utifrån resultaten.

Full textAbstract:
This thesis investigates the application. of fuzzy logic techniques and user modelling to the process of information retrieval (IR) from the World Wide Web (WWW). The research issue is whether this process can be improved through such an application. The exponential rise of information itself as an invaluable global commodity, coupled with .acceierating development in. computing and telecommunications, and boosted by networked information sources such as the WWW, has led to the development of tools, such as search engines, to facilitate information search and retrieval. However, despite their sophistication, they are unable effectively to. address users' information. needs. Also, as the-WWW can be seen as a dynamic, continuously changing global information corpus, these tools suffer from the problems of irrelevancy and redundancy. Therefore, in order to overcome these problems and remain effective, IR systems need to become 'intelligent' in some way. It is from this premise that the focus of this research has developed. Initially, theoretical and investigative research into the areas ofIR from electronic sources and the nature of the Internet (including the WWW) revealed that highly sophisticated systems are being developed and there is a drive towards the integration of, for example, electronic libraries, COROM networks, and the WWW. Research into intelligent IR, the use of AI techniques to improve the IR process, informed an evaluation of various approaches. This revealed that a munber of techniques, for example, expert systems, neural networks and semantic networks, have been employed, with limited success. Owing to the nature of the WWW, though, many of the previous AI approaches are inapplicable as they rely too much on extensive knowledge of the retrieval corpus. However, the evaluation suggested that fuzzy logic, with its inherent ability to capture partial knowledge within fuzzy sets, is a valid approach. User modelling research indicated that adaptive user stereotypes are a fruitful way to represent different types of user and their information need. Here, these stereotypes are represented as fuzzy sets, ensuring flexibility and adaptivity. The goal of the reported research. then, was not to. develop an 'intelligent agent' but to apply fuzzy logic techniques and user modelling to the process of user query formulation, in order to test the research issue. This issue was whether the application of these techniques could improve the IR process. A prototype system, the Fuzzy Modelling Query Assistant (FMQA), was developed that attempts intelligently to assist the user in capturing their information need. The concept was to refine the user's query before submitting it to an existing search engine, in order to improve upon the IR results of using the search tool alone. To address the research issue, a user study of the FMQA was performed. The design and conduct is reported in depth. The study results were analysed and the findings are given. The results indicate that,. for certain types of user especially, the FMQA does provide improvement in the IR process, in terms of the results. There is a critical review of the research aims in the light of the results, conclusions are drawn and recommendations for future research given.

Every scientific research begins with a literature review that includes an extensive bibliographic search. Such searches are known to be difficult and time-consuming because of the vast amount of topical material existing in today's ever-changing technology base. Keeping up-to-date with related literature and being aware of the most recent publications require extensive time and effort.
The need for a WWW-based software tool for collecting and providing access to this scientific body of knowledge is undeniable. The study explained herein deals with this problem by developing an efficient, advanced, easy-to-use tool, WebBiblio, that provides a globally accessible WWW environment enabling the collection and dissemination of searchable bibliographies comprised of abstracts and keywords. This thesis describes the design, structure and features of WebBiblio, and explains the ideas and approaches used in its development. The developed system is not a prototype, but a production system that exploits the capabilities of the WWW. Currently, it is used to publish three VV&T bibliographies at the WWW site: http://manta.cs.vt.edu/biblio. With its rich set of features and ergonomically engineered interface, WebBiblio brings a comprehensive solution to solving the problem of globally collecting and providing access to a diverse set of bibliographies.Master of Science

We develop a method for extracting and internalizing web site form submissions which we refer to as web operations. To begin the process, a user performs a sample submission of the form. From that submission, our system determines all of the necessary information to store the web operation. Through a simple user interface the user can view and modify the web operation to the extent that he wants or needs to. With the operation now stored, the user can invoke the operation without browsing to the web site on which the operation was originally contained. By utilizing the web site information extraction techniques contained in the Haystack information management system, we give the user the option to extract information off of web operation results pages. Thus, when using our system to the fullest extent, a user can invoke web operations and view and make use of the results without viewing any web pages.

Full textAbstract:
När en grafisk profil för en spännande ny internationell webbtidning för ungdomar skall göras är det viktigt att tänka på hur färg och form påverkar våra känslor. Experiment med färg som har gjorts av ledande färgpsykologer och färgvetare som Goethe, Itten, Lüscher och Karl Ryberg bevisar att färg har en stor psykologisk påverkan på människan. Internet är ett väldigt effektiv kommunikationsmedium och för att kommunicera effektivt är det inte bara orden, utan även färgerna och formerna på webbsidorna som skall vara väl genomtänkta. Vilka färger kopplar ungdomar i Sverige och Chile ihop med vissa känslor? Vilka former kopplas ihop med samma känslor? Svaren på de frågorna sammanställdes och analyserades efter svaren på en enkät om färg och form som delades it till två högstadieskolor i Borlänge, Sverige och en i Santiago, Chile.

Antigamente as informações que as organizações utilizavam durante a sua gestão eram suficientemente armazenadas em arquivos. A própria aplicação era responsável pela manipulação dos dados e pela função de guardá-los de maneira segura. No entanto, a sociedade evoluiu com tamanha rapidez que as organizações começaram a gerar uma quantidade cada vez maior de informação e, também, a rapidez de acesso às informações armazenadas tornou-se cada vez mais importante. Os antigos sistemas de arquivos tornaram-se complexos sistemas de armazenamento de informações responsáveis por gerir grandes volumes de dados, chamados Sistemas Gerenciadores de Banco de Dados - SGBD’s. Devido à complexidade dos bancos de dados e à necessidade de sua operação ininterrupta surge a tarefa do Administrador, cuja função é assegurar que os bancos de dados permaneçam operantes, íntegros e rápidos. Para realizar suas tarefas o Administrador precisa contar com boas ferramentas de modo a tornar as intervenções no banco de dados rápidas e seguras. Existem no mercado, boas ferramentas para administração de banco de dados. No entanto, são todas proprietárias, possuem custo elevado e apresentam deficiências quando o DBA e o BD estão localizados logicamente em redes de dados distintas. Para tentar resolver este problema, este trabalho se propõe a desenvolver uma ferramenta de administração de banco de dados que o DBA possa utilizar para gerenciar os bancos de dados, utilizando a Web como instrumento.

Full textAbstract:
The most common application of hypertext today is found on the World Wide Web, with the numbers of sites and potential users increasing continually. Hypertext systems are characterized by hyperlinks that allow users nonsequential access to the documents contained within them. Because users are not constrained to read through these documents in a linear manner, new problems may arise not found in traditional paper versions.
These problems are generally characterized by a sense of being "lost" within a hypertext system. The user may not know exactly where they are or how to get where they want to be. They have lost many of the visual cues that indicate position found in ordinary texts like books. Navigational aids or overview maps have been suggested as a means to help counteract this problem. These navigational aids can take a standard table-of-contents and extend it dynamically or provide a completely new paradigm of browsing. To that extent, many new varieties of maps (including three-dimensional ones) have been developed but not thoroughly studied. As well, it may be theorized that users of differing cognitive abilities may be helped or hindered by such devices.
An empirical study was performed to investigate the effect of multidimensional maps. Three different navigational aids were examined which varied the way pages are displayed along one, two or three dimensions. Two hypertext systems were also where one was roughly twice the size of the other. The participants were given a search task twice to examine performance on page revisits. Finally, three cognitive tests were given to view the effects of individual differences. These included a spatial ability, verbal ability and visual memory test.
The results indicated that no performance differences existed between the different navigational aids. However, a significant interaction was present between the maps and the type of Web site; smaller Web sites benefited from the 3D navigational aid. It is theorized that an observed effect for hypertext system was due to site complexity as opposed to size. The results from the cognitive ability measures were mixed. People with low verbal ability scores took longer to locate answers. People with high spatial ability scores found more answers and had scores that were less sensitive to the type of navigational aid used. No significant differences were discovered between people of high and low visual memory abilities.Master of Science

Esta pesquisa tem como foco principal os atributos favoráveis à motivação de uso de um site, especificamente um portal educacional. Concentra-se no levantamento de atributos usuais para a construção de sites na Internet, sendo primeiramente levantados em bibliografias e, paralelamente, junto a profissionais responsáveis pela construção de um portal educacional para o mercado brasileiro. Com a definição dos atributos mais importantes, buscou-se a constatação de seu uso em três portais educacionais, dois deles concorrentes ao portal estudado, por meio do uso da ferramenta de benchmarking. Com os dados sobre os atributos, partiu-se para a fase de avaliação de tais atributos com usuários finais de um portal educacional, para a verificação se tais atributos eram relevantes na busca e uso de tal site. A pesquisa concentrou-se em um grupo fechado de respondentes, por serem efetivos usuários do portal educacional e poderem, com suas respostas, colaborar de forma significativa para o avanço da pesquisa. Os resultados obtidos revelam importantes considerações sobre a construção de sites – especificamente portais educacionais – mas por serem atributos gerais podem formar uma base para analise de outros sites em construção.

Full textAbstract:
Os motores de busca utilizam o WebGraph formado pelas páginas e seus links para atribuir reputação às páginas Web. Essa reputação é utilizada para montar o ranking de resultados retornados ao usuário. No entanto, novas versões de páginas com uma boa reputação acabam por distribuir os votos de reputação entre todas as versões, trazendo prejuízo à página original e também as suas versões. O objetivo deste trabalho é especificar novos escores que considerem todas as versões de uma página Web para atribuir reputação para as mesmas. Para atingir esse objetivo, foram propostos quatro escores que utilizam a detecção de versões para atribuir uma reputação mais homogênea às páginas que são versões de um mesmo documento. Os quatro escores propostos podem ser classificados em duas categorias: os que realizam mudanças estruturais no WebGraph (VersionRank e VersionPageRank) e os que realizam operações aritméticas sobre os escores obtidos pelo algoritmo de PageRank (VersionSumRank e VersionAverageRank). Os experimentos demonstram que o VersionRank tem desempenho 26,55% superior ao PageRank para consultas navegacionais sobre a WBR03 em termos de MRR, e em termos de P@10, o VersionRank tem um ganho de 9,84% para consultas informacionais da WBR99. Já o escore VersionAverageRank, apresentou melhores resultados na métrica P@10 para consultas informacionais na WBR99 e WBR03. Na WBR99, os ganhos foram de 6,74% sobre o PageRank. Na WBR03, para consultas informacionais aleatórias o escore VersionAverageRank obteve um ganho de 35,29% em relação ao PageRank.Search engines use WebGraph formed by the pages and their links to assign reputation to Web pages. This reputation is used for ranking show for the user. However, new versions of pages with a good reputation distribute your votes of reputation among all versions, damaging the reputation of original page and also their versions. The objective of this work is to specify the new scores to consider all versions of a Web page to assign reputation to them. To achieve this goal, four scores were proposed using the version detection to assign a more homogeneous reputation to the pages that are versions of the same document. The four scores proposed can be classified into two categories: those who perform structural changes in WebGraph (VersionRank and VersionPageRank) and those who performs arithmetic operations on the scores obtained by the PageRank algorithm (VersionSumRank and VersionAverageRank). The experiments show that the performance VersionRank is 26.55% higher than the PageRank for navigational queries on WBR03 in terms of MRR, and in terms of P@10, the VersionRank has a gain of 9.84% for the WBR99 informational queries. The score VersionAverageRank showed better results in the metric P@10 for WBR99 and WBR03 information queries. In WBR99, it had a gain of 6.74% compared to PageRank. In WBR03 for random informational queries, VersionAverageRank showed an increase of 35.29% compared to PageRank.

Artificial Intelligence Lab, Department of MIS, University of ArizonaResearch in information retrieval (IR) has advanced significantly in the past few decades. Many tasks, such as indexing and text categorization, can be performed automatically with minimal human effort. Machine learning has played an important role in such automation by learning various patterns such as document topics, text structures, and user interests from examples. In recent years, it has become increasingly difficult to search for useful information on the World Wide Web because of its large size and unstructured nature. Useful information and resources are often hidden in the Web. While machine learning has been successfully applied to traditional IR systems, it poses some new challenges to apply these algorithms to the Web due to its large size, link structure, diversity in content and languages, and dynamic nature. On the other hand, such characteristics of the Web also provide interesting patterns and knowledge that do not present in traditional information retrieval systems.

Full textAbstract:
O sucesso da Internet como plataforma de distribuição de sistemas de informação encoraja organizações a disponibilizar serviços presentes em seus sistemas legados nesse ambiente. Uma parte desses sistemas foi desenvolvida na fase inicial do desenvolvimento das aplicações cliente/servidor para banco de dados, usando ambientes visuais com interfaces gráficas tipo WIMP, implementadas sob o paradigma procedimental/estruturado, baseado em objetos e eventos. Como conseqüência, produziu-se sistemas legados difíceis de manter, evoluir e adaptar a novas tecnologias e arquiteturas, pois os projetos desenvolvidos não seguiam, na maioria das vezes, os bons preceitos e práticas modernas defendidas na Engenharia de Software. O objetivo deste trabalho é propor uma metodologia para migrar sistemas legados com as características citadas acima para a plataforma Web. O processo de migração proposto destaca duas estratégias: a elaboração de modelos de classes conceituais da aplicação e o tratamento dado à interface do usuário, para serem utilizados na reconstrução de uma nova aplicação. O processo é baseado em técnicas e métodos de engenharia reversa, que visa obter abstrações por meio de análise estática e dinâmica da aplicação. Na análise dinâmica, destaca-se o mecanismo para recuperar aspectos dos requisitos funcionais do sistema legado e representá-los na ferramenta denominada UC/Re (Use Case para Reengenharia). Todos os artefatos gerados durante o processo podem ser armazenados em um repositório, representando os metamodelos construídos na metodologia. Para delimitar e exemplificar o processo, escolheu-se como domínio de linguagem de programação do software legado, o ambiente Delphi (sob a linguagem Object Pascal). É proposto também um ambiente CASE, no qual é descrito o funcionamento de um protótipo que automatiza grande parte das funcionalidades discutidas nas etapas do processo. Algumas ferramentas desenvolvidas por terceiros são empregadas na redocumentação do sistema legado e na elaboração dos modelos UML do novo sistema. Um estudo de caso, apresentando uma funcionalidade específica de um sistema desenvolvido em Delphi, no paradigma procedimental, é usado para demonstrar o protótipo e serve de exemplo para a validação do processo. Como resultado do processo usando o protótipo, obtém-se o modelo de classes conceituais da nova aplicação no formato XMI (formato padrão para exportação de modelos UML), e gabaritos de páginas em HTML, representando os componentes visuais da interface original na plataforma Web.

Full textAbstract:
Contextual information retrieval (CIR) is a critical technique for today’s search engines in terms of facilitating queries and returning relevant information. Despite its importance, little progress has been made in its application, due to the difficulty of capturing and representing contextual information about users. This thesis details the development and evaluation of the contextual SERL search, designed to tackle some of the challenges associated with CIR from the World Wide Web. The contextual SERL search utilises a rich contextual model that exploits implicit and explicit data to modify queries to more accurately reflect the user’s interests as well as to continually build the user’s contextual profile and a shared contextual knowledge base. These profiles are used to filter results from a standard search engine to improve the relevance of the pages displayed to the user. The contextual SERL search has been tested in an observational study that has captured both qualitative and quantitative data about the ability of the framework to improve the user’s web search experience. A total of 30 subjects, with different levels of search experience, participated in the observational study experiment. The results demonstrate that when the contextual profile and the shared contextual knowledge base are used, the contextual SERL search improves search effectiveness, efficiency and subjective satisfaction. The effectiveness improves as subjects have actually entered fewer queries to reach the target information in comparison to the contemporary search engine. In the case of a particularly complex search task, the efficiency improves as subjects have browsed fewer hits, visited fewer URLs, made fewer clicks and have taken less time to reach the target information when compared to the contemporary search engine. Finally, subjects have expressed a higher degree of satisfaction on the quality of contextual support when using the shared contextual knowledge base in comparison to using their contextual profile. These results suggest that integration of a user’s contextual factors and information seeking behaviours are very important for successful development of the CIR framework. It is believed that this framework and other similar projects will help provide the basis for the next generation of contextual information retrieval from the Web.

Web environment has developed into the largest source of electronic documents, so it would be very useful, to process this information automatically. This is however not a trivial problem. Most documents are written in HTML (Hypertext Markup Language), which does not support semantic description of the content. The goal of this work is to create modular system for information extraction and further processing of this information from HTML documents. Further processing of information means to store this information in XML document or relational database. System modularity makes it possible to use various information extraction and storing methods, thus the system can be used for various tasks.

Atualmente, o use de ferramentas de apoio ao projeto de circuitos integrados é indispensável, devido a complexidade desses circuitos que aumenta incessantemente. O presente trabalho discute um modelo para integração de ferramentas em um ambiente único - formando um framework - com o objetivo de acelerar o processo de concepção dos circuitos através da automatização de tarefas, livrando o projetista de tarefas como a administração de recursos distribuídos, o armazenamento de arquivos e assim por diante. 0 framework proposto é baseado em um ambiente amplamente conhecido: o World Wide Web. Ao utilizar o World Wide Web como base para o ambiente de integração de ferramentas, muito trabalho é poupado, uma vez que grande parte da interface gráfica e do controle de rede do framework já esta implementada. A facilidade de acesso ao WWW também é uma grande vantagem, no caso de uma equipe de projeto distribuída. A integração das ferramentas segue dois modelos. O primeiro é utilizado em ferramentas de maior interação com o usuário. Nesse caso, a ferramenta deve ser re-escrita para ser integrada ao ambiente na forma de applets - programas escritos com a linguagem Java que podem ser anexados a documentos WWW. O segundo modelo é utilizado em ferramentas com pouca ou nenhuma interação com o usuário. Essas ferramentas são integradas através de entradas e saídas de dados. Usando applets Java, a funcionalidade e a interface gráfica da ferramenta são independentes de plataforma e podem ser anexadas a documentos WWW, o que faz com que a ferramenta possa ser executada na maquina do projetista. reduzindo a carga de processamento do servidor do framework. Já as ferramentas integradas usando o segundo modelo devem ser executadas no servidor devido compatibilidade, já que são dependentes de plataforma. Objetivando fundamentar e validar a proposta do framework baseado no WWW, uma revisão bibliográfica é apresentada, em ambos os temas: World Wide Web e CAD Frameworks. A partir dessa revisão e da especificação proposta, implementou-se um protótipo integrando ferramentas usando ambos os mecanismos descritos. A descrição do protótipo e suas características são apresentadas, bem como alguns pontos críticos que devem ser alvo de pesquisa em trabalhos futuros.Nowadays the use of design automation tools for integrated circuits is more necessary than ever, due to the always increasing complexity of such circuits. This work discusses a model for tool integration in a framework, in order to speed up the design flow, saving the designer from tasks such as distributed resources and file administration. This framework is based on a well known environment: the World Wide Web. When using the World Wide Web as the base for the framework, a lot of work is saved since most of the user's graphic interface and the network management is already done. The availability of the WWW is also interesting, in the case of a distributed design team. The integration of the tools follows two models. The first is that of interactive tools. In this case, the tool must be re-written to be integrated to the environment as applets - applications written using the Java language that can be attached to WWW documents. The second model is used on poorly or non-interactive tools. In this case, the tool is integrated by its input and output streams. Using Java applets, the tools functionality and graphical interface are platform independent and may be attached to a WWW hyperdocument. Thus, the tool may run at the user's machine. Using this architecture, it is possible to divide the processing task among the framework server and the designer's machines. The tools that are integrated using the second model must run on the framework server due to compatibility issues, since they are platform dependent. In order to validate the proposed web based design framework, a literature review is presented in both themes: World Wide Web and CAD Frameworks. From the literature review and the proposed specification, a prototype was implemented, integrating tools using both the mechanisms described. The description of the prototype and its features are presented, as well as some critical points that need to be improved in future works.

A World Wide Web em poucos anos de existência se tornou uma importante e essencial fonte de informação e a localização e recuperação de informações na Internet passou a ser um grande problema a ser resolvido. Isto porque a falta de padronização e estrutura adequada para representação dos dados, que é resultado da liberdade de criação e manipulação dos documentos, compromete a eficácia dos modelos de recuperação de informação tradicionais. Muitos modelos foram então desenvolvidos para melhorar o desempenho dos sistemas de recuperação de informação. Com o passar dos anos surge assim uma nova área de pesquisa a extração de dados da web que, ao contrário dos sistemas de recuperação, extrai informações dos documentos relevantes e não documentos relevantes de conjunto de documentos. Tais estudos viabilizaram a integração de informações de documentos distribuídos e heterogêneos, que foram baseados nos mesmos modelos aplicados a banco de dados distribuídos. Neste trabalho é apresentado um estudo que tem como objetivo materializar informações contidas em documentos HTML de modo que se possa melhorar o desempenho das consultas em relação ao tempo de execução quanto à qualidade dos resultados obtidos. Para isso são estudados o ambiente web e as características dos dados contidos neste ambiente, como por exemplo, a distribuição e a heterogeneidade, aspectos relacionados à maneira pela qual as informações estão disponibilizadas e como estas podem ser recuperadas e extraídas através de regras sintáticas. Finalizando o estudo são apresentados vários tipos de classificação para os modelos de integração de dados e é monstrado em detalhes um estudo de caso, que tem como objetivo demonstrar a aplicação das técnicas apresentadas ao longo desta pesquisa.

A crescente utilização de computadores e a popularização da Internet contribuem cada vez mais para que usuários não especialistas em informática tenham acesso a sistemas computacionais. Tais usuários possuem diferentes habilidades, formações e idades que devem ser levadas em consideração no projeto de uma boa interface. No entanto, no projeto de interfaces web é muito difícil identificar essas características do público alvo, tendo em vista que ele é bastante diversificado. Assim, construir uma interface que atenda os requisitos de todos os usuários de um site não é uma tarefa fácil. Se o projetista tivesse uma maneira de conhecer o seu público, grande parte dos problemas de interação entre usuário e interface poderiam ser resolvidos. Assim, a fim de auxiliar na tarefa de conhecer o público que um site possui, várias técnicas estão disponíveis. Independente das características dos usuários de sites web, a sua principal necessidade consiste em encontrar a informação desejada de modo fácil e rápido. Ainda que seja possível identificar o comportamento de todos os usuários em um site, torna-se difícil disponibilizar informações de forma clara e simples para todos. Para isto, um site adaptativo, que se ajusta automaticamente a cada usuário de acordo com seus padrões de comportamento, é muito útil. Sites adaptativos são desenvolvidos com base em técnicas que auxiliam o projetista na tarefa de personalizar páginas web e, por este motivo, são chamadas de técnicas de personalização. O objetivo desta dissertação é investigar, desenvolver e experimentar uma técnica de personalização de interfaces web voltada especificamente para sites institucionais. Este tipo de site é voltado à divulgação de produtos e serviços de uma instituição e, normalmente, é composto por um grande número de páginas estruturadas de acordo com a estrutura organizacional da instituição. Essa característica permite o agrupamento de usuários por funções ou cargos. A técnica proposta neste trabalho é baseada em perfis de usuários, onde a personalização ocorre em dois níveis: nível de grupos de usuários e nível de usuários individuais, denominados respectivamente de macro perfil e micro perfil. Um estudo de caso realizado na intranet da Agência Nacional de Telecomunicações – ANATEL foi utilizado para aprimorar e validar a técnica. Foi desenvolvido um protótipo de site institucional personalizado, o qual foi disponibilizado, utilizado e avaliado por um grupo de usuários previamente selecionados. O processo de construção do protótipo assim como da avaliação e seus resultados são também descritos neste trabalho.

CyberPsychology and Behavior, 3(1), 97-102. Abstract: In a recent review of the empirical findings on hypermedia and learning outcomes, Dillon and Gabbard (1998) concluded that contrary to many people's assumptions, the use of hypermedia-based instructional systems in education had not produced significant learning gains. Indeed, their review concluded that such instructional technologies rarely showed any benefit for learners over existing paper- or lecture-based instructions. While it is commonplace these days to dismiss as irrelevant any media comparison study, the Dillon and Gabbard review went further, also examining comparisons made between alternative hypermedia implementations (a within-media comparison) and between single and group learners employing this technology. Since hypermedia is the underlying technology of the World Wide Web, their findings made depressing reading for those of us who believe that this technology is important and could be put to powerful instructional use.
The present issue contains papers from many leading theorists who advocate the use and exploitation of information technologies such as hypermedia and the World-Wide Web in our classrooms, and I am not completely in disagreement with them. However, I wish to question the very assumptions on which the use of the Web and standalone hypermedia applications are based. What I aim to provide in this paper is a sense of the gaps in our knowledge, and to speculate on why education is so poorly served by the wonderful technologies that are within our grasp.

Full textAbstract:
Neste trabalho, é realizado um estudo dos processos de avaliação de alunos em ambiente WBT (Web Based Training). Para tanto, foram analisadas várias ferramentas de avaliação disponíveis no mercado. Com base nestas análises, foi proposto um sistema de gerência de questões e aplicação de avaliações, onde o termo “gerência” é utilizado com o objetivo de (i) atender requisições dos professores para elaboração de avaliações, (ii) escolher o nível de dificuldade das questões que comporão a avaliação e (iii) usar estratégias interativas para aplicação de provas, como por exemplo, a utilização de níveis de dificuldade progressivos das questões submetidas aos alunos, dependendo de suas respostas anteriores. Integrando o sistema de gerência de questões foi proposto um módulo de auto-avaliações, com retorno imediato para o aluno sobre qual é a resposta correta juntamente com uma explicação do professor, auxiliando no entendimento do estudante sobre a matéria ao invés de simplesmente atribuir determinada nota. Enfim, foi implementado um protótipo demonstrando a viabilidade das idéias presentes no modelo de avaliação aqui proposto. A proposta conceitual estabelecida para o modelo é bem mais ampla e flexível do que a atual versão da implementação realizada.
