Les connaissances décisionnelles sont un type particulier de connaissances dont le but est de décrire des processus de prise de décision. En cancérologie, ces connaissances sont généralement regroupées dans des guides de bonnes pratiques cliniques. Leur publication est assurée par des organismes médicaux suite à un processus d'édition collaboratif complexe. L'informatisation des guides a conduit à la volonté de formaliser l'ensemble des connaissances contenues de manière à pouvoir alimenter des systèmes d'aide à la décision. Ainsi, leur édition peut être vue comme une problématique d'acquisition des connaissances. Dans ce contexte, le but de cette thèse est de proposer des méthodes et des outils permettant de factoriser l'édition des guides et leur formalisation. Le premier apport de cette thèse est l'intégration des technologies du Web social et sémantique dans le processus d'édition. La création du wiki sémantique OncoLogiK a permis de mettre en oeuvre cette proposition. Ainsi, un retour d'expérience et des méthodes sont présentés pour la migration depuis une solution Web statique. Le deuxième apport consiste à proposer une solution pour exploiter les connaissances décisionnelles présentes dans les guides. Ainsi, le framework KCATOS définit un langage d'arbres de décision simple pour lequel une traduction reposant sur les technologies du Web sémantique est développée. KCATOS propose en outre un éditeur d'arbres, permettant l'édition collaborative en ligne. Le troisième apport consiste à concilier dans un même système les approches pour la création des guides de bonnes pratiques informatisés : l'approche s'appuyant sur les connaissances symbolisée par KCATOS et l'approche documentaire d'OncoLogiK. Leur fonctionnement conjoint permet de proposer une solution bénéficiant des avantages des deux approches. De nombreuses perspectives sont exposées. La plupart d'entre elles visent à améliorer les services aux utilisateurs et l'expressivité de la base de connaissances. En prenant en compte le travail effectué et les perspectives, un modèle réaliste visant à faire du projet Kasimir un système d'aide à la décision complet est proposé / Decision knowledge is a particular type of knowledge that aims at describing the processes of decision making. In oncology, this knowledge is generally grouped into clinical practice guidelines. The publication of the guidelines is provided by medical organizations as a result of complex collaborative editing processes. The computerization of guides has led to the desire of formalizing the knowledge so as to supply decision-support systems. Thus, editing can be seen as a knowledge acquisition issue. In this context, this thesis aims at proposing methods and tools for factorizing editing guides and their formalization. The first contribute on of this thesis is the integration of social semantic web technologies in the editing process. The creation of the semantic wiki OncoLogiK allows to implement this proposal. Thus, a feedback and methods are presented for the migration from a static web solution. The second contribution consists in a solution to exploit the knowledge present in the decision-making guides. Thus, KcatoS framework defines a simple decision tree language for which a translation based on semantic web technologies is developed. KcatoS also proposes an editor of trees, allowing collaborative editing online. The third contribution is to combine in a single system approaches for the creation of clinical guidelines: the approach based on the knowledge symbolized by KcatoS and the documentary approach symbolized by OncoLogiK. Their joint operation can propose a solution benefiting from the advantages of both approaches. Many future works are proposed. Most of them aim at improving services to users and the expressiveness of the knowledge base. Taking into account the work and prospects, a realistic model to create a decision-support system based on clinical guidelines is proposed

Esta dissertação visa apresentar a trajetória e os resultados da análise da atividade oficina de construção colaborativa de textos multimodais em ambiente virtual wiki, ministrada a 52 usuários do Telecentro instalado na Biblioteca Pública Municipal Monteiro Lobato, na cidade de São Paulo. Os dados foram coletados de junho de 2008 a fevereiro de 2009, período de duração das cinco turmas da oficina. Utilizando os preceitos da teoria da atividade (Leontiev, 1978; Engeström, 1997; Nardi, 1996) e principalmente o conceito de contradições apontado pela teoria (Engeström, 1997) procura-se identificar, classificar e problematizar, na análise de dados, as contradições relacionadas a aspectos linguísticos, cognitivos, sociais, culturais e técnicos que surgem entre os elementos que compõem a atividade (sujeito, ferramentas, objeto, regras, comunidade e divisão do trabalho) durante a realização da oficina. A análise das contradições da atividade demonstra, contudo, que professora e alunos não encontraram soluções em todos os casos. Concluiu-se nesta pesquisa que a análise das contradições da atividade foi profícua para a compreensão detalhada das relações entre os componentes da atividade em todos os seus níveis. Também foi compreendido que uma análise dessa importância deve sempre motivar e ser seguida pelo planejamento e implementação de um modelo de reformulação da atividade que incorpore ações de transformação e inovação, que efetivamente levem aos resultados esperados. Embora o escopo desta pesquisa não tenha permitido que isso fosse feito, algumas sugestões de como se poderia tentar fazê-lo em pesquisas futuras são esboçadas e apresentadas no final do trabalho. / This dissertation aims to present the history and the results of the analysis of the activity: workshop for collaborative construction of multimodal texts in a virtual environment wiki, taught to 52 users of the Telecentro located at the Public Municipal Library Monteiro Lobato, in the city of São Paulo. Data were collected from June 2008 to February 2009. Using the precepts of activity theory (Leontiev, 1978; Engeström, 1997; Nardi, 1996) and especially the concept of contradictions, pointed out by that theory (Engeström, 1997), this research seeks to identify, classify and discuss the contradictions related to the linguistic, cognitive, social, cultural and technical aspects arising among the elements of the activity (subject, tools, object, rules, community and division of labor) during the workshop. The analysis done shows however, that teacher and students did not find solutions to all the contradictions that emerged. We conclude that this study\'s analysis of the contradictions of the activity was helpful for the detailed understanding of the relationship among the components of the activity, at all levels. An analysis of this importance should motivate and be followed by planning and implementing of a reformulation model that incorporates actions for change and innovation, and effectively, leading to expected results. Although the scope of this research did not allow it to be done, some suggestions on how one might do so in future research are outlined at the end of this study.

This thesis concentrates on wiki systems as an ICT tool of knowledge management. Thesis is divided into two general parts - the first deals with the theoretical concepts such as: data, information, knowledge or community. Doctoral thesis reflects the way in which these terms are understood in different scientific disciplines, especially knowledge management. The second part deals with wiki systems, which are viewed not just in general and theoretical level, but they are also approached practically. The work provides an analysis of possible uses of wiki as a tool for knowledge management in the organization. At the end of the work there are published case studies of specific wiki system implementations (both local and from abroad) to illustrate the work's conclusions. The work has confirmed that the wiki system can be successfully used as a tool of knowledge management. The output of the work on the theoretical level is author's "circular model of know-ledge"; while on the practical level the output is determination of suitable areas for dep-loyment of wiki systems in the organization. In the end author quotes a number of case studies (both foreign and local) wiki systems implementation.

Duomenų „surinkimas“ – tai procesai, skirti tam tikros informacijos, apie dominančią objektinę sritį, kaupimui. Tokių duomenų „apdorojimo“ sąvoka apima jų filtravimą, priežiūrą, saugojimą, analizę ir pan. Kriterijai pagal kuriuos duomenys yra renkami, taip pat metodika ir filtravimas juos padaro specifiniais arba „paskirstytais“. Paskirstytų duomenų surinkimo ir apdorojimo sąvoka yra gana plati ir apima ne tik elementariausius Web klausimynus ar testus, bet ir dideles sistemas, skirtas analizuoti ir apdoroti struktūrizuoto (pvz.: XML) duomenų srauto informaciją, prireikus ją konvertuoti, saugoti ir adaptuoti. / Term WIKI defines ideas and basis for data collection and management, necessary and mandatory methods required to ensure quality of collectible data. The purpose of this master work is analysis of existing solutions of data collecting and analysis systems in order to create a new unique WIKI community based system for price and other information (related to products on the market) analysis. System target – build up user manageable knowledge base for recognition of changes in the market, fast, easy and cheapest products information withdraw. It gives an overview of the best data collection approaches structure, techniques and logic, data analysis and collection methods (based on the system target), also proposes created model and defines means and tools, for model creation and realization.

Enterprise Wikis haben sich zu einem wichtigen Bestandteil der Corporate Intranets entwickelt. Aufgrund ihrer Nutzungsoffenheit und hohen Flexibilität lassen sich Enterprise Wikis für vielfältigste Einsatzzwecke verwenden. Dabei ist die Nutzungsmotivation der Mitarbeiter ein kritischer Stellhebel für den Erfolg von Enterprise Wikis. In diesem Beitrag wird auf Basis des aus der Arbeitspsychologie stammenden Konzepts „motivation sources inventory“ von BARBUTO & SCHOLL eine Untersuchung mittels Online-Befragung mit 95 Teilnehmern aus 10 verschiedenen Unternehmen durchgeführt. Hierbei wurde ersichtlich, dass Enterprise Wikis von den Befragten durchweg als wertvoll eingeschätzt werden. Weiterhin stellen die Nützlichkeit von Enterprise Wikis für die tägliche Arbeit sowie das Bestreben, Kollegen bzw. das eigene Team zu unterstützen wichtige Quellen der Motivation dar. Bezüglich der intrinsischen Prozessmotivation bei Enterprise Wikis, d.h. Spaß an der Benutzung, konnten stark divergierende Meinungen festgestellt werden. Hingegen ist Lob bzw. Reputation nur für einen kleinen Teil der Befragten motivierend, im Enterprise Wiki beizutragen.
