Abstract:
Today's complex environmental and organizational pressures lead to business teams distributed along the dimensions of space, time, and computing resources. Distributed teams often need to collaborate to solve complex problems together. Many information systems support simple information sharing, however group research has shown that productive problem solving extends far beyond this. Group Support Systems (GSS) researchers and product reviewers suggest that simple discussion tools fall short of supporting additional phases of group problem solving. Research into distributed collaboration is needed to understand this complex domain. This dissertation describes an investigation into distributed collaboration to design, develop, implement, evaluate, and iteratively refine a prototype World-Wide-Web (Web) based distributed GSS. The research addresses requirements derivation, architecture design, prototype implementation, evaluation, iterative refinement, and the nature of roles played by participants. The literature review examines the areas of meeting analysis, hypertext, the Web, GSS, distributed GSS, collaborative interface design, group facilitation and systems engineering. The systems development research method is applied according to the following stages: Conceptual Framework Development, Requirements Identification, Systems Architecture Development, Systems Design, Systems Implementation and Systems Evaluation. An evolutionary prototyping approach incorporates evaluator suggestions and evolving technology into the system. Systems requirements are derived from the literature review, interviews with dozens of GSS researchers, practitioners and developers and hundreds of users from around the world. The initial specification employs the data model and interface design of an existing face-to-face GSS. A Distributed GSS architecture, consisting of a Hypertext Markup Language (HTML)/JavaScript client interface and a centralized HyperText Transport Protocol (HTTP)/Common Graphical Interface (CGI) server, is proposed, designed, and implemented. The logical data model is extended for distributed collaboration through identification of relevant data entities and relationships. The interface is extended through iterative prototyping based on observations, user feedback and technical enhancements. Prototype systems functionality is extended based on lab and field observations and direct feedback from users. Research contributions include a new distributed architecture, knowledge about distributed GSS interfaces, functionality, facilitation, leadership and participation, a prototype for additional research, and knowledge about the processes and group dynamics for distributed teams.

Abstract:
Collaboration among teachers in some shape or form is becoming increasing popular among the educational system. The goal of this thesis is to determine whether teachers find value in collaboratively working in a Web environment and if we can use collaboration to improve educational content. We took a Web-based intelligent tutoring system, called ASSISTments, and incorporated a collaboration feature allowing teachers from around the Web to work together to create content for their students. The previous ASSISTments model did not allow for any form of collaboration; teachers using ASSISTments were not able to modify each other's content. By creating the opportunity for teachers to work together, we hypothesized that the educational content within ASSISTments would improve. To help improve education content among ASSISTments, we also deemed it necessary to improve the tool that teachers used to create problems for their students. Using surveys and interviews, we obtained feedback from teachers supporting our changes of the ASSISTments system and validating our claims that they found value in collaboratively working in a Web-based environment.

Abstract:
Today, advancements in the information technologies increased the significance of electronic business in the world. Besides the numerous advantages provided by these advancements, competition has also increased for the enterprises. In this competitive environment, companies have to access information faster and response to the changes quickly. In a supply chain, it is a highly possible that one of the partners may defect in providing its services. When these exceptional cases occur, the pending parties have to establish transitory collaborations to replace the missing partner promptly in order not to suffer this deficiency economically. Companies need to know the competences and capabilities of their prospective business partners before establishing partnerships. Furthermore, the reputations of the candidate partners have to be known to avoid possible regrettable partnerships. In this thesis, we have developed a trust and reputation model that can be used over supply chains to determine and exploit the reputation of providers in transitory collaboration formation. The trust model takes the behaviors of providers, consumers into account and combines multiple criteria to aggregate a single reputation value. Experimental results show that, our model provides a robust and reliable reputation mechanism addressing a number of issues that have not been covered in the related studies. In addition to this, an implementation of the model is realized within a Web application and the functionalities have been exposed as Web Services. The interoperability of the Web Services have been ensured through standard GS1 XML documents, which are utilized and extended in scope of the thesis. Furthermore, client interaction is provided through Web based user interfaces and REST services.

Abstract:
<p>Our objective in this thesis work is to analyze and manage the log files which are generated after a number of experiments series on different groups using C3Fire simulation environment. It includes analyzing and extracting information from log files, and then maintaining this information in a database. This should be presented with a web interface through ICEfaces Ajax framework for Java. Log Files are generated after a number of experiments series on the different groups. All sequences and information related to task performed by team in group is organized in session log files. The work is divided into different steps; first step is to analyze and extract data from log files, and properly arrange it in several different tables in a database, for this MySQL database is used to store the information. The web interface of log file management system is implemented using ICEfaces Ajax framework, and is based on the statistics of log files generated from the C3Fire environment.  User would be able to add/remove the log files, also can view or edit the details of each session log file in database through web interface. Different events can be generated, and logged for the session information.</p><p>C3Fire is an environment that supports training and research in team collaboration. The environment is mainly used in command, control and communication research, and in training of team decision making. Many humanitarian relief operations are doing their work without having any practice. When some disaster events occur, they cannot perform their jobs effectively. Effective and efficient relief operation is the need of humanity; even that’s not enough to move teams to the disaster place at right time; communication and co-ordination among the team members is the big factor to make effective and well-organized work. C3Fire is a simulation system which provides the training for team members to handle such type of disaster events, and makes the work more proficient at that time by doing effective coordination.</p>

Abstract:
The distribution of real-time GIS (Geographic Information System) data among users is now more important than ever as it becomes increasingly affordable and important for scientific and government agencies to monitor environmental phenomena in real-time. A growing number of sensor networks are being deployed all over the world, but there is a lack of solutions for their effective monitoring. Increasingly, GIS users need access to real-time sensor data from a variety of sources, and the data must be represented in a visually-pleasing way and be easily accessible. In addition, users need to be able to collaborate with each other to share and discuss specific sensor data. The real-time acquisition, analysis, and sharing of sensor data from a large variety of heterogeneous sensor sources is currently difficult due to the lack of a standard architecture to properly represent the dynamic properties of the data and make it readily accessible for collaboration between users. This thesis will present a JEE-based publisher/subscriber architecture that allows real-time sensor data to be displayed collaboratively on the web, requiring users to have nothing more than a web browser and Internet connectivity to gain access to that data. The proposed architecture is evaluated by showing how an AJAX-based and a Flash-based web application are able to represent the real-time sensor data within novel collaborative environments. By using the latest web-based technology and relevant open standards, this thesis shows how map data and GIS data can be made more accessible, more collaborative and generally more useful.

Abstract:
Mestrado em Engenharia de Computadores e Telemática<br>With the overwhelming amount of biomedical textual information being produced, several manual curation efforts have been set up to extract and store concepts and their relationships into structured resources. Since manual annotation is a very demanding and expensive task, computerized solutions were developed to perform such tasks automatically. Nevertheless, high-end information extraction techniques are still not widely used by biomedical research communities, mainly due to the lack of standards and limitations in usability. Interactive annotation tools intend to fill this gap, taking advantage of automatic techniques and existing knowledge bases to assist expert curators in their daily tasks. This thesis presents Egas, a web-based platform for biomedical text mining and assisted curation with highly usable interfaces for manual and automatic inline annotation of concepts and relations. Furthermore, a comprehensive set of knowledge bases are integrated and indexed to provide straightforward concept normalization features. Additionally, curators can also rely on real-time collaboration and conversation functionalities allowing discussing details of the annotation task as well as providing instant feedback of curators interactions. Egas also provides interfaces for on-demand management of the annotation task settings and guidelines, and supports standard formats and literature services to import and export documents. By taking advantage of Egas, we participated in the BioCreative IV interactive annotation task, targeting the assisted identification of protein-protein interactions described in PubMed abstracts related to neuropathological disorders. Thereby, when evaluated by expert curators, Egas obtained very positive scores in terms of usability, reliability and performance. These results, together with the provided innovative features, place Egas as a state-of-the-art solution for fast and accurate curation of information, facilitating the task of creating and updating knowledge bases in a more consistent way.<br>Com o acréscimo da quantidade de literatura biomédica a ser produzida todos os dias, vários esforços têm sido feitos para tentar extrair e armazenar de forma estruturada os conceitos e as relações nela presentes. Por outro lado, uma vez que a extração manual de conceitos compreende uma tarefa extremamente exigente e exaustiva, algumas soluções de anotação automática foram surgindo. No entanto, mesmo os sistemas de anotação mais completos não têm sido muito bem recebidos no seio das equipas de investigação, em grande parte devido às falhas a nível de usabilidade e de interface standards. Para colmatar esta falha são necessárias ferramentas de anotação interativa, que tirem proveito de sistemas de anotação automática e de bases de dados já existentes, para ajudar os anotadores nas suas tarefas do dia-a-dia. Nesta dissertação iremos apresentar uma plataforma de anotação de literatura biomédica orientada para a usabilidade e que suporta anotação manual e automática. No mesmo sentido, integramos no sistema várias bases de dados, no intuito de facilitar a normalização dos conceitos anotados. Por outro lado, os utilizadores podem também contar com funcionalidades colaborativas em toda a aplicação, estimulando assim a interação entre os anotadores e, desta forma, a produção de melhores resultados. O sistema apresenta ainda funcionalidades para importar e exportar ficheiros, gestão de projetos e diretivas de anotação. Com esta plataforma, Egas, participámos na tarefa de anotação interativa do BioCreative IV (IAT), nomeadamente na identificação de interações proteína-proteína. Depois de avaliado por um conjunto de anotadores, o Egas obteve os melhores resultados entre os sistemas apresentados, relativamente à usabilidade, confiança e desempenho.

Abstract:
Originating in the theory of distributed computing, the optimistic consistency control method known as Operational Transformation (OT) has been studied by researchers since the late 1980s. Algorithms were devised for managing the concurrent nature of user actions and for maintaining the consistency of replicated data as changes are introduced by multiple geographically-distributed users in real-time. Web-Based Collaborative Platforms are now essential components of modern organizations, with real-time protocols and standards such as WebSocket enabling the development of online collaboration tools to facilitate information sharing, content creation, document management, audio and video streaming, and communication among team members. Products such as Google Docs have shown that centralized web-based co-editing is now possible in a reliable way, with benefits in user productivity and efficiency. However, as the demand for effective real-time collaboration between team members continues to increase, web applications require new synchronization algorithms and architectures to resolve the editing conflicts that may appear when multiple individuals are modifying the same data at the same time. In addition, collaborative applications need to be supported by scalable distributed backend services, as can be achieved with "serverless" technologies. While much existing research has addressed problems of optimistic consistency maintenance, previous approaches have not focused on capturing the dynamic client-server interactions of OT systems by modeling them as real-time systems using Finite State Machine (FSM) theory. This thesis includes an exploration of how the principles of control theory and hierarchical FSMs can be applied to model the distributed system behavior when processing and transforming HTML DOM changes initiated by multiple concurrent users. The FSM-based OT implementation is simulated, including with random inputs, and the approach is shown to be invaluable for organizing the algorithms required for synchronizing complex data structures. The real-time feedback control mechanism is used to develop a Web-Based Collaborative Platform based on a new OT integration algorithm and architecture that brings "Virtual DOM" concepts together with state-of-the-art OT principles to enable the next generation of collaborative web-based experiences, as shown with implementations of a rich-text editor and a 3D virtual environment.

Abstract:
The use of Web-Based-Collaboration-Systems (WBCS) continues to grow as part of information technology development in the Architecture-Engineering-Construction (AEC) industry. WBCS provide different media channels to support collaboration across geographical distributed teams. However, many companies are still hesitant to integrate WBCS. This research provides an understanding of how WBCS are used in practice. Most distinctively, it obtained practice data from several major US architecture firms and examined about 30,000 transactions produced during actual design and planning projects as practicing architects, engineers and consultants used WBCS. The study investigated what information was used and exchanged among participants during the different design stages. This was related to the different media channels of WBCS. The raw project data has been coded and transformed into secondary data through computer-supported content analysis. Based upon categories from previous literature, such as communication, coordination and design theories, the data has been analyzed for sender, receiver, channel and content of information transmitted. The content has been characterized into work tasks, information handling behavior and design activities. Additional interviews with industry professionals produced information that had not been documented through WBCS and that corroborated the analytical findings. The combination of theory, quantitative, and qualitative analysis has been synthesized into a portrait of WBCS usage that was validated through triangulation. The analysis of digital records of design communication from practice through content analysis is a new research methodology in AEC. The evidence supporting design methods theory shows the changes in tasks and information handling in regards to the project phases. It indicates that the most frequent loops of design activity are Evaluation- Analysis-Synthesis and Evaluation-Synthesis-Evaluation. It documents the actual usage of WBCS based on descriptive statistics and Markov models. WBCS was used primarily as a document repository and calendaring tool. The remote team members used it more frequently than centrally located participants. The study shows the limitations of WBCS: none of the verbal communication was captured. More significant, the entire email exchange took place outside the WBCS. WBCS was used very extensively, if the implementation of the system supported the organizational structure and vice versa.

Abstract:
In the construction industry, the adoption of concurrent engineering principles requires the development of effective enabling IT tools. Such tools need to address specific areas of need in the implementation of concurrent engineering in construction. Collaborative decision-making is an important area in this regard. A review of existing works has shown that none of the existing approaches to collaborative decision-making adequately addresses the needs of distributed construction project teams. The review also reveals that fuzzy logic offers great potential for application to collaborative decision-making. This thesis describes a Web-based collaborative decision-making system for construction project teams using fuzzy logic. Fuzzy logic is applied to tackle uncertainties and imprecision during the decision-making process. The prototype system is designed as Web-based to cope with the difficulty in the case where project team members are geographically distributed and physical meetings are inconvenient/or expensive. The prototype was developed into a Web-based software using Java and allows a virtual meeting to be held within a construction project team via a client-server system. The prototype system also supports objectivity in group decision-making and the approach encapsulated in the prototype system can be used for generic decision-making scenarios. The system implementation revealed that collaborative decision-making within a virtual construction project team can be significantly enhanced by the use of a fuzzybased approach. A generic scenario and a construction scenario were used to evaluate the system and the evaluation confirmed that the system does proffer many benefits in facilitating collaborative decision-making in construction. It is concluded that the prototype decision-making system represents a unique and innovative approach to collaborative decision-making in construction project teams. It not only contributes to the implementation of concurrent engineering in construction, but also it represents a substantial advance over existing approaches.

Abstract:
This study validated and evaluated the feasibility of a web-based electronic behavior assessment system, ‘eBA’, designed to facilitate collaboration between caregivers and service providers (behavior analysts) in conducting indirect functional behavior assessment (FBA). In Phase 1, the content and the web architecture of the eBA were validated and refined through a formative evaluation by five behavior analysts. In Phase 2, the eBA system was pilot tested with 10 service providers and 10 caregivers using a post-test only control group design to examine the efficiency and quality of the system and identify the levels of satisfaction with the system by the service providers and caregivers. The results indicated that the eBA system components were appropriate to conduct indirect FBA and useful for use by caregivers and service providers collaboratively, gathered quality information, and showed higher levels of caregiver and service provider satisfaction, compared to traditional paper-pencil format of assessment.

Abstract:
A tecnologia de componentes de software é propícia para encapsular questões técnicas de implementação e favorecer o reúso entre aplicações, o que é particularmente relevante no desenvolvimento de aplicações colaborativas na Web. Este trabalho utiliza a plataforma Groupware Workbench nesse contexto. A aplicação social Arquigrafia foi a principal motivadora dessa evolução. O Arquigrafia é um ambiente colaborativo para o estudo de arquitetura e compartilhamento de imagens fortemente baseado em colaboração e inteligência coletiva. Como o conceito de inteligência coletiva é muito amplo e mal definido, foi realizada uma análise de domínio e uma classificação das técnicas e seus usos nos sistemas atuais. Também foi feito o mapeamento e a implementação das funcionalidades do Arquigrafia em componentes do Groupware Workbench e executada uma avaliação da plataforma em quatro vertentes, sendo elas: arquitetura de componentes; suporte à colaboração; arquitetura técnica; e percepção dos desenvolvedores. Limitações tecnológicas e conceituais foram identificadas, como por exemplo, o modelo de mapeamento objeto-relacional e questões ligadas à flexibilidade. Essas limitações e colocações foram tratadas e avaliadas na plataforma, resultando em melhorias na arquitetura dos componentes e na simplificação do código. O Groupware Workbench no geral mostrou-se viável para o desenvolvimento de uma aplicação colaborativa real na Web 2.0.<br>Software components technology is favorable to encapsulate implementation technical issues and encourage the reuse among applications. These characteristics are particularly relevant in the development of web-based collaborative applications. This work evaluates and evolves the Groupware Workbench platform in this context. The social application Arquigrafia was the main motivation for this evolution. Arquigrafia is a collaborative environment for the study of architecture and image sharing strongly based on collaboration and collective intelligence. Since the concept of collective intelligence is very broad, we performed a domain analysis and a classification of its use in current systems. We also implemented the Arquigrafia features using Groupware Workbench components and evaluated the platform in four areas: components architecture; collaboration support; technical architecture; and developers perspective. We identified technological and conceptual limitations, as for example, the adopted object-relational mapping model and issues related to the flexibility of the platform. These limitations were treated and evaluated. We noted improvements in the architecture of the components and code simplification. As a result, the Groupware Workbench was a feasible solution for developing the Arquigrafia application.

We used, as a method, the FODA (Feature Oriented Domain Analysis) adapted with 3C collaboration model to classify and patterns for computer-mediated interaction to describe the collaborative features. To implement the commons features of these applications, a component kit compatible with an infrastructure named Groupware Workbench was defined and developed. An experiment was done to evaluate the artifacts generated by the domain engineering and a case study was done to evaluate coverage and applicability of the developed components in a real context, a social network for architectural images sharing named Arquigrafia Brasil.

Abstract:
Organisations today operate in a complex, unpredictable, globalised, and competitive business environment and challenging marketplace, emphasis on just-in-time deliveries and service quality through the integration of resources. In response to the changing business dynamics, web-based EDI (WEDI) has been adopted by the global container shipping industry to cost-effectively utilise available resources to build and remain its competitive advantage. To improve the current understanding of WEDI adoption factors, this research explores inter-organisational collaboration of WEDI adoption, focusing on the organisational adoption stage and examine how business level social and relational factors influence WEDI adoption in the context of the container liner shipping industry. Based on theoretical and literature reviews on previous EDI adoption, in particular to three key inter-organisational system adoption empirical research (including Lee and Lim, 2005; Boonstra and de Vries, 2005; Zhu et al., 2006), an integrated research model was established of which features ‘Social Resources' of (trading partner power, trading partner dependence and social network effect), ‘Relational Resources' of (trading partner trust, top management commitment and guanxi, ‘Reward' of (perceived interests), and ‘Technological State' of (technological trust and e-readiness) as prominent antecedents. Through E-mail and Web Survey approach, we examine the nine independent constructs in the research model quantitatively on a dataset of 164 respondents from the top 20 leading container shipping liner in year 2009 and 195 respondents of the top 20 leading container shipping liner in 2012 by 3 case studies through online surveys. After examining its reliability, validity and correlation of the constructs, PLS structural Equation Modelling was applied to test hypotheses. The empirical results update how firms exchange business dada, in particular to the use of WEDI in the industry. This study demonstrated that ‘Social Resources' of trading partner power, trust and guanxi, positively associated with the perceived interest of WEDI adoption. Relational Resources' of trading partner trust, top management commitment and guanxi positively associated with the perceived interest of WEDI adoption. It also confirms the nine constructs to be positively association the WEDI adoption decisions. Drawing upon social exchange theory, we argue that firms simultaneously modify and adjust their social and relational resources to affect other firms' expected benefit as a reward. Overall, based on a rigorous empirical analysis of two different international dataset, this research provides valuable and the most updated insights into a set of key factors that influence WEDI adoption. By recognising what may influence WEDI adoption in the context of the container liner shipping, this study will be useful in suggesting strategies to overcome the constraints that inhibit adoption. Researchers will benefit from the study's theoretical insights and explore further WEDI adoption and diffusion patterns. Practitioners who learn why organisations adopt WEDI and what the related factors are that influence the adoption process will make better strategic decisions concerning the adoption of WEDI.

Abstract:
L’évolution technologique du web durant ces dernières années a favorisé l’arrivée d’environnements virtuels collaboratifs pour la modélisation 3D à grande échelle. Alors que la collaboration réunit dans un même espace partagé des utilisateurs distants géographiquement pour un objectif de collaboration commun, les ressources matérielles qu'ils apportent (calcul, stockage, 3D ...) avec leurs connaissances sont encore trop rarement utilisées et cela constitue un défi. Il s'agit en effet de proposer un système simple, performant et transparent pour les utilisateurs afin de permettre une collaboration efficace à la fois sur le volet computationnel mais aussi, bien entendu, sur l'aspect métier lié à la modélisation 3D sur le web. Pour rendre efficace le passage à l’échelle, de nombreux systèmes utilisent une architecture réseau dite "hybride", combinant client serveur et pair-à-pair. La réplication optimiste s'adapte bien aux propriétés de ces environnements répartis : la dynamicité des utilisateurs et leur nombre, le type de donnée traitées (3D) et leur taille. Cette thèse présente un modèle pour les systèmes d’édition collaborative en 3D sur le web. L'architecture cliente (3DEvent) permet de déporter les aspects métiers de la 3D au plus près de l’utilisateur sous la forme d’évènements. Cette architecture orientée événements repose sur le constat d’un fort besoin de traçabilité et d’historique sur les données 3D lors de l’assemblage d’un modèle. Cet aspect est porté intrinsèquement par le patron de conception event-sourcing. Ce modèle est complété par la définition d’un intergiciel en pair-à-pair. Sur ce dernier point, nous proposons d'utiliser la technologie WebRTC qui présente une API familière aux développeurs de services en infonuagique. Une évaluation portant sur deux études utilisateur concernant l’acceptance du modèle proposé a été menée dans le cadre de tâches d’assemblage de modèles 3D sur plusieurs groupes d’utilisateurs<br>Web technologies evolutions during last decades fostered the development of collaborative virtual environments for 3D design at large scale. Despite the fact that collaborative environments gather in a same shared space geographically distant users in a common objective, the hardware ressources of their clients (calcul, storage, graphics ...) are often underused because of the challenge it represents. It is indeed a matter of offering an easy-to-use, efficient and transparent collaborative system to the user supporting both computationnal and 3D design visualisation and business logic needs in heterogeneous web environments. To scale well, numerous systems use a network architecture called "hybrid", combining both client-server and peer-to-peer. Optimistic replication is well adapted to distributed application such as 3D collaborative envionments : the dynamicity of users and their numbers, the 3D data type used and the large amount and size of it.This document presents a model for 3D web-based collaborative editing systems. This model integrates 3DEvent, an client-based architecture allowing us to bring 3D business logic closer to the user using events. Indeed, the need of traceability and history awareness is required during 3D design especially when several experts are involved during the process. This aspect is intrinsec to event-sourcing design pattern. This architecture is completed by a peer-to-peer middleware responsible for the synchronisation and the consistency of the system. To implement it, we propose to use the recent web standard API called WebRTC, close to cloud development services know by developers. To evaluate the model, two user studies were conducted on several group of users concerning its responsiveness and the acceptance by users in the frame of cooperative assembly tasks of 3D models

Abstract:
Medizinische Volumenvisualisierung ist ein wertvolles Werkzeug zur Betrachtung von Volumen- daten in der medizinischen Praxis und Lehre. Eine interaktive, stereoskopische und kollaborative Darstellung in Echtzeit ist notwendig, um die Daten vollständig und im Detail verstehen zu können. Solche Visualisierung von hochauflösenden Daten ist jedoch wegen hoher Hardware- Anforderungen fast nur an speziellen Visualisierungssystemen möglich. Remote-Visualisierung wird verwendet, um solche Visualisierung peripher nutzen zu können. Dies benötigt jedoch fast immer komplexe Software-Deployments, wodurch eine universelle ad-hoc Nutzbarkeit erschwert wird. Aus diesem Sachverhalt ergibt sich folgende Hypothese: Ein hoch performantes Remote- Visualisierungssystem, welches für Stereoskopie und einfache Benutzbarkeit spezialisiert ist, kann für interaktive, stereoskopische und kollaborative medizinische Volumenvisualisierung genutzt werden. Die neueste Literatur über Remote-Visualisierung beschreibt Anwendungen, welche nur reine Webbrowser benötigen. Allerdings wird bei diesen kein besonderer Schwerpunkt auf die perfor- mante Nutzbarkeit von jedem Teilnehmer gesetzt, noch die notwendige Funktion bereitgestellt, um mehrere stereoskopische Präsentationssysteme zu bedienen. Durch die Bekanntheit von Web- browsern, deren einfach Nutzbarkeit und weite Verbreitung hat sich folgende spezifische Frage ergeben: Können wir ein System entwickeln, welches alle Aspekte unterstützt, aber nur einen reinen Webbrowser ohne zusätzliche Software als Client benötigt? Ein Proof of Concept wurde durchgeführt um die Hypothese zu verifizieren. Dazu gehörte eine Prototyp-Entwicklung, deren praktische Anwendung, deren Performanzmessung und -vergleich. Der resultierende Prototyp (CoWebViz) ist eines der ersten Webbrowser basierten Systeme, welches flüssige und interaktive Remote-Visualisierung in Realzeit und ohne zusätzliche Soft- ware ermöglicht. Tests und Vergleiche zeigen, dass der Ansatz eine bessere Performanz hat als andere ähnliche getestete Systeme. Die simultane Nutzung verschiedener stereoskopischer Präsen- tationssysteme mit so einem einfachen Remote-Visualisierungssystem ist zur Zeit einzigartig. Die Nutzung für die normalerweise sehr ressourcen-intensive stereoskopische und kollaborative Anatomieausbildung, gemeinsam mit interkontinentalen Teilnehmern, zeigt die Machbarkeit und den vereinfachenden Charakter des Ansatzes. Die Machbarkeit des Ansatzes wurde auch durch die erfolgreiche Nutzung für andere Anwendungsfälle gezeigt, wie z.B. im Grid-computing und in der Chirurgie.

Abstract:
碩士<br>台北醫學院<br>醫學資訊研究所<br>90<br>British epidemiologist Archie Cochrane published Effectiveness and Efficiency: Random Reflections on Health Services in 1972, appealing for the importance of randomized controlled trials (RCTs) with all exertion. In 1979, he further proposed aggregating and constantly updating RCTs result in each field of medical expertise for systematic review to provide reliable medical evidence for clinical implementation. Meanwhile, he pointed out the fact that medical resources should be applied to the treatment authenticated by discreet researches, so as to provide reasonable medical service. Most of the clinical experience of a doctor comes from the senior’s instructions and the records in textbooks, that both fail to guarantee the conformation to the latest medical evidence. Without knowing how to determine and judge the research report or quote the research objects with similar characteristics to one’s own patients, the doctor will fail to obtain correct information, even it he/she checks through medical records. For the past few years, Evidence Based Medicine (EBM) emerged universally on purpose of enhancing the quality of medical treatment. Briefly speaking, the belief of EBM is applying the results of the carefully-designed records able to solve clinical problems directly to the realistic treatment for the patients while evaluate its treatment efficiency for the sake of improving the quality of the medical treatment and the application of the resources. In 1993, 60 researchers led by Sir. Chalmers summoned the 1st Cochrane Annual Meeting in Oxford, establishing Cohrane Center officially. The most noticeable contribution of the cooperation network to EBM was the production of high-quality systematic review, with 2432 systematic review in total by May 2002, becoming the physical knowledge collection in EBM. Since 1999, ChangHua Christian Hospital, WanFang Hospital, Chang-Gung Memorial Hospital and Taiwan University Hospital in Taiwan have successively opened classes in the research and implementation of EBM, focusing on the content and application of medical evidence in each expertise. However, the lack of an organization and system to record and pass around the results has been a pity in Taiwan’s Evidence Medicine. To address such a problem, two aspects are available: partaking in the organization of Cochrane, making use of the resources and tools in the organization and establishing Taiwan’s EBM center alone. Even though much effort has been devoted for the past three years, the Cochrane Taiwan Center still remains as an unreachable dream because of the reality of International politics. As a result, establishing EBM Taiwan Center has become an inevitable tendency in order to unroll the advantages of Taiwan’s medical field. This thesis, from the aspect of medical resources, researched on the EBM system that provide EBM results─systematic review─efficiently and rapidly in Taiwan’s medical field that lacks manpower and cooperative organizations. In the meantime of researching the organization, goals, operation and regulations of Cochrane Center that has put EBM into practice, new technologies were applied to the improvement over the EBM Off-Line in Cochrane to self-develop Taiwan’s EBM systematic review system. Hopefully, by the time of certain quantity and quality of the collected data are achieved, Cochrane Center will cooperate with Taiwan with its professional considerations. Five steps of EBM must be abided by to create the systematic review system for the EBM organization, in which medical resources experts are required to assist in the practice of step 2 and step 3 in the five-step process to generate database and application system. This research aimed at treating migraine with acupuncture in accordance with the five steps. By establishing three Web-based systems to construct key review steps that assist the systematic review of EBM. The three Web-Based system applications are: 1.Topic Related Medical Literature Database : Acupuncture on Migrane Database. 2.RCT Critical Appriasal System 3.Systematics Review System of EBM The research of this thesis, through the three systems, focused on the treatment of migraine with acupuncture, attempted to review the migraine treatment efficiency with acupuncture in the randomized controlled trials in Chinese and English documents systematically from the aspect of EBM. By reviewing the quality of the experimental approaches, this research synthetically analyzed and evaluated the benefits and efficiency of the migraine treatment with migraine, which in turn to evaluate the quality and physical appraisal of the approach in randomized Controlled Trials documents and use the accurate conclusions as the reference for the instruction on clinical decisions.

Abstract:
博士<br>國立臺灣大學<br>資訊工程學研究所<br>96<br>In this dissertation we focus on collaborative systems. We study the concept,technical issues involved, and the design and implementation of a collaborative system. We emphasize the efficiency and flexibility of building a collaborative system that supports diverse content-based interactions among people through network communications over the Internet. A main objective of this dissertation is to build a collaborative framework that is flexible, extensible, and can be used to construct any type of collaborative system. Our work can be summarized by following the hierarchy of knowledge building. For data delivering, we create an event-based collaboration awareness development framework that supports both data-centric and operation-centric methods. We also create some special dynamic and flexible event generation tools to enhance the degree of reusability and automation. With this collaboration aware framework, we further create a complicated collaborative algorithm visualization tool and wrap a single user text editor into a collaborative editor. For information sharing platform, we build a ShareToneDesktop platform with the capabilities that support customizable content types, and workflow-enabled content management developed by the 3rd parties. We also establish a content based integration mechanism for composing synchronous collaborative components into an asynchronous information sharing platform. For knowledge management, we build a computational problem solving environment for algorithmic researchers, teachers and students who make heavy use of the components created in the previous two parts in practice. The problem solving environment serves as a test case of the applicability and usability of these components of which a large scale collaborative system is composed. As a result, we incorporate all the software components and development tools into the ShareTone website http://www.sharetone.org. We hope this ShareTone website can serve as a basis for constructing even more powerful and versatile collaborative system to help people do collaboration and build group knowledge more efficiently and effectively.

Abstract:
碩士<br>臺灣大學<br>資訊網路與多媒體研究所<br>98<br>Nowadays, there are many web-based collaborative whiteboard systems all over the Internet. But, they do not provide functions that support teacher-student interaction in the classroom. Those systems do not clearly divide user’s role into teacher and student and do not have a good interface to support student interaction with lessons and teachers. Moreover, some of those whiteboards are implemented by using Adobe Flash, which needs to be installed as a browser plug-in. Therefore, in this thesis, we design and develop the web-based collaborative system for the classroom, which support the interaction between the teacher and the students. The system provides tools and functions that can be utilized by teacher for creating better learning environment. Besides, the client side is entirely implemented with HTML and javaScript. Therefore, users do not need to install any browser plug-ins in order to use this application. In our system, the orbited server is used for making the application real-time. PHP is used for developing the application on the server side. Raphael javaScript library is used for creating SVG graphic element on the client browser. Prototype javaScript library is used for creating client side application. And, MySQL is used as the content storage.

For the purpose of satisfying wide varieties of people’s needs, wants and desires, design problems have become more and more complex, time-consuming and cost lots of money. With the idea of concurrent design, it should be a wise way to have all people with necessary specialties to collaboratively work out design solutions together simultaneously. However, it seems difficult, if not impossible, to get many specialists physically together to do the design work at the same time and at the same place. The purpose of this study is tried to investigate the construction of a Web-based Co-design system. It takes the advantage of world wide web(www) technology and create a collaborative design workplace, to make it easier for designers virtually work together from different design sites. This study examined the Web-based collaborative design system through intensive observation and interview with design specialists and testing with prospective users. A simulative software named “Face 2 Face” was created through the experimental system. After the experiments, the results of the study obviously show that “Face 2 Face” is much more superior than the current system. The results could be applied to the configuration of appropriate user interfaces and eventually set up a web-based collaborative design system.

Abstract:
Although much effort has been invested to build applications that support group work, collaborative applications have not found easy success. The cost of adopting and maintaining collaborative applications has prevented their widespread use, especially among small distributed groups. Application developers have had difficulties recognizing the extra effort required by groups to use collaborative applications and how to either reduce this effort or provide other benefits to compensate for the extra work. These problems have limited the success of collaborative applications, which have not attained the same level of productivity improvements that single user applications have achieved. In this thesis we present a framework that describes the types of computer support that can facilitate the work of distributed engineering design groups. Our framework addresses support for web-based groups in particular because we believe the web can be a powerful medium for collaboration if accommodated properly. We show how the concepts in this framework can be implemented by prototyping a web-based engineering decision support system. Our framework is a synthesis of ideas motivated by an examination of literature in various fields that share a common interest in collaborative work. It can influence application development by helping developers become aware of the types of support should be considered to aid web-based collaborative design.<br>Graduation date: 1997

Abstract:
碩士<br>國立高雄應用科技大學<br>資訊管理系<br>98<br>Education is a fundamental resource for human learning, and instructors play important role in helping learners improve their learning performance. Cooperative learning is one of strategies used to assist learners' learning, but the approach of traditional cooperative learning did not consider completely the needs of learners for the group formation. As a result, it might raise barriers to cooperative learning. Therefore, the purpose of this study is to construct a dynamic group mechanism based on trust networks and knowledge capabilities of learners. The concept, Friend of a Friend, is used to grasp the degree of trusted friends in learners’ trust networks. In addition, knowledge capabilities of learners are considered as the basic requirements for the group formation. The course, object-oriented programming, has been used in this study as the topic of cooperative learning. The participants in the experiment were first-year undergraduate students who are divided into the experimental group and control group. The results showed that the experimental group with the dynamic grouping mechanism has better performance than the control group in term of learning performance and sense of group identity. The results also showed that the approach proposed this study can improve the quality of knowledge-sharing and learning performance.

Abstract:
博士<br>中原大學<br>機械工程研究所<br>98<br>The diverse product requirements and just-in-time production are challenges in the injection mold industry today. The sequential process in mold development does not guarantee timely success any more. Therefore, this study proposes a web-based and collaborative configuration for conceptual mold design with knowledge management. This system integrated CAD and web-based management seamlessly by the dedicated application programming interface (API) functions. Based on the flow of navigating design, the feature-oriented approaches and concept of skeleton design are implemented to provide a standardized, collaborative, intellectualized, and customized platform. Not only does the system prevent probable engineering mistakes and accumulates valuable knowledge, but it also reuses the intact feature information from conceptual to detailed mold design and efficiently shortens detailed mold design processes by the deployment of collaborative design. The results show significant time savings over conventional mold design processes by 50% in practical case studies.

碩士<br>國立高雄應用科技大學<br>工業工程與管理系碩士班<br>93<br>Because of vigorous development of information technology, we can communicate with each other through Internet no matter where we are. With the current trend of globalization, enterprises need to design products to correspond with clients’ requirement without delay in order to curtail the period that products will be on the market and accelerate the rate of development so as to raise the competitiveness. In recent years, information exchange between companies has been a tendency through collaborative assignment. This research implements a workflow engine to develop the design of collaborative products through the technique of Web Service. It is not just using the concept of collaborative assignment on the development of products but also making the system run more flexible and variable. Regardless of the common business process or product design, they all could be run on this system. And it uses the technique of Web Service so that it can be able to inherit the advantage of Web Service such as public network transmission standard and passing through Firewall with SOAP etc and makes Web Service be able to be free from restriction of the network and communicate with different platforms and programs. In this way, when we are designing the new products, it can help us conduct the coordination design with other enterprises through this system and promote the efficiency of design.

Abstract:
La Web Social y la Web Semántica han impactado en la forma en que la creación de conocimiento se ha llevado a cabo en la Web. La Web Social promociona la participación de los usuarios para crear y editar contenido y conocimiento en la Web. La proliferación de contenido y la necesidad de tener una administración automatizada de esta información disparó la aparición de la Web Semántica. Actualmente, la Web Social y la Web Semántica conviven y comparten un mismo tema: un mejor manejo del conocimiento. Sin embargo, la mayoría de la información en la Web Social no es parte de la Web Semántica, y la información de la Web Semántica no es utilizada para mejorar a la Web Social. Esta tesis presenta un enfoque innovador para estimular una co-evolución entre la Web Semántica y la Web Social: las fuerzas que impulsan la Web Social y las herramientas que llevan a cabo la Web Semántica trabajando en conjunto con el fin de tener beneficios mutuos. En este trabajo afirmamos que la co-evolución entre la Web Social y la Web Semántica mejorará la generación de información semántica en la Web Semántica, y mejorará la producción de conocimiento en la Web Social. Esto invita a responder las siguientes preguntas: ¿Cómo puede incluirse la generación de datos semánticos en las actividades de los usuarios de la Web Social? ¿Como puede definirse la semántica de un recurso web en un entorno social? ¿Cómo puede inyectarse en la Web Social las nuevas piezas de información extraídas de la Web Semántica? ¿Poseen las comunidades de la Web Social convenciones generales que deban ser respetadas? Con el fin de mejorar la Web Semántica con las fuerzas de la Web Social, en este trabajo se proponen dos enfoques de Social Semantic Tagging: P-Swooki que permite a usuarios de una wiki semántica gestionar anotaciones semánticas permitiendo completar el proceso de construcción de conocimiento, y Semdrops que permite a los usuarios describir en forma semántica cualquier recurso de la Web tanto en un espacio de conocimiento personal como en un espacio compartido. Además, con el fin de mejorar el contenido de la Web Social, proponemos BlueFinder: un sistema de recomendación que detecta y recomienda la mejor manera de representar en un sitio de la Web Social, información que es extraída de la Web Semántica.

Abstract:
碩士<br>國立臺灣大學<br>工業工程學研究所<br>96<br>Owing to the increasing amount of communication contents in real world, how to cut down the transmission time through web applications has become a vital issue. At the same time, the functionality and reusability of website resources are still of concern. However, traditional framework of Client / Server network is insufficient for achieving the desired performances. Therefore, Distributed Network and Agent-based Network are getting much more attention. To provide a service-oriented platform for meeting different needs and bridging the communications while offering various web services with distributed network architecture will definitely be a significant objective in oncoming development of web technology. In terms of these trends, the thesis proposes an information platform derived from the concept of Service-oriented Architecture (SOA). The information platform follows a real-world condition for people to access. For example, users in an organization can login to this site and use the flow chart or procedures with web services provided. Besides the web services, the thesis also applies the technique of Socket to support the functionality on the platform and to lesson the loadings of web servers for mending the time delays in data transmission. In security issues, login, registry, and cookies mechanisms are entirely encrypted. The administrator of this platform can easily view users’ status and login time by the constructed GMPP web service so as to do web management. Additionally, this platform also offers users of Event-Recorder to record all acts done on the web site, and the stored data could be checked lately when needed. In addition to those web services, the thesis constructs a web-based factorial simulation system of photolithography area in semiconductor fabrication as well. Through the application, one can get the dispatching results and performance indexes including average cycle time and throughput. There is also an auxiliary functionality as scheduler selector, which seeks for the best schedulers by putting Neural Network, Support Vector Machine (SVM), and Fuzzy Logic in use. Finally, after the simulation procedure, the Principal Component Analysis (PCA) based Statistical Process Control (SPC) method would be used to find the most contributing factors and do the statistical diagnosis. The managers of the factories would then be able to keep in pace with the conditions within fabrication and manufacturing processes.

Abstract:
博士<br>國立成功大學<br>工程科學系碩博士班<br>99<br>One goal of collaborative learning is to maximize the learning performance of all participating students. In order to achieve this aim, the first step is to consider how to assist instructors in forming well-structured collaborative learning groups with a good work atmosphere to promote successful outcomes for all members. Nevertheless, when the instructors face a large number of students, especially in computer-supported collaborative learning environments, simultaneously considering several grouping criteria to form the students in an appropriate collaborative learning context is almost impossible. To address this issue, this study develops a group formation problem to model the formation of collaborative learning groups based on students’ prior knowledge. Prior knowledge is an essential foundation for learning, as it affects the interpretation, organization, assimilation, and absorption of new instructions. Generally, tests are used to help instructors evaluate students’ prior knowledge. Nevertheless, conventional testing approaches usually assign only a score to students, and this may mean that both students and instructors are unable to accurately identify misunderstandings in the formers’ prior knowledge. Therefore, this study proposes a prior knowledge measurement model to assist instructors in diagnosing student’s prior knowledge. Moreover, this study is based on a novel approach called particle swarm optimization (PSO) to propose a group formation model for forming well-structured collaborative learning groups based on students’ prior knowledge. To demonstrate that the group formation model is an applicable and robust approach, a series of systematical evaluations were conducted to analyze the performance of the group formation model. The results show that the model can efficiently and effectively form collaborative learning groups based on students’ prior knowledge. In addition, an experiment was conducted to evaluate the efficacy of the proposed approach with regard to improving teaching and learning performance. The results show that the system is able to improve students’ learning motivation and enhance teaching and learning performance. In addition, the diagnosis evaluation results show that the proposed system can accurately diagnose the students’ prior knowledge.

Abstract:
碩士<br>國立高雄師範大學<br>資訊教育研究所<br>93<br>The purpose of this study is to implement a web bookmark system for professional community of teachers at compulsory education in Taiwan. As those teachers are looking for teaching materials on the web, they feel an extra burden beyond daily instruction tasks. They can hardly locate what materials they want within a short time. however, demand for community bookmarks is getting stronger while the internet has offered many useful teaching materials for education. This study proposes combining ontological and collaborative filtering approaches to recommend web-based teaching materials or share domain ontologies among professional teachers’ community. The recommendation is based on Pearson correlation matrix. The approach is collective intelligence to enhance teaching materials’ sharing. This methodology of this study consists of three stages. Firstly, the Google searching engine is used as a web service interface. Secondly, domain ontologies of nine-year curriculum is constructed in web-based bookmark system and visually presented knowledge maps. Thirdly, a collaborative filtering algorithm provides teachers with locating web teaching materials on the dynamic nodes. The collaborative filtering is included for recommending teaching materials or ontologies duplication. Additionally, in our study, we utilize the SCTNET's(http://sctnet.edu.tw) teaching material share as basis of emulation data by randomized bookmarks for each teachers. Two primary parameters used in this study are threshold for peer annotations and Pearson correlation among teachers. The optimal recall and precision value for these two parameters in terms of bookmark thresholds and Pearson correlation are 3 and 0.75. The contributions of this paper are as follows: (a) This study extends the traditional bookmark into web-based edition; (b) Web-based bookmark enhances teaching materials’ sharing among professional community; (c) Development of collaborative filtering provides reliable recommendations on ontologies or teaching materials; (d). Knowledge map is visually represented for those teachers to understand the whole knowledge picture. Finally, the implications of this study are also included.
