Tagging et folksonomies : pragmatique de l'orientation sur le Web / Tagging and Folksonomies : pragmatics of orientation on the WebCrépel, Maxime 30 November 2011 (has links)
Cette recherche propose une analyse des usages des systèmes de tagging sur le Web. Au delà d'un simple outil personnel de « catégorisation ordinaire » des ressources en ligne, les classifications produites à partir de l'indexation libre de tags, nommées folksonomies, permettent aux internautes de produire des « prises » physiques et interprétatives quideviennent un support aux formes de navigation sociale. Ces réseaux de traces numériques permettent aux internautes de se repérer et d'agir dans l'univers complexe et abondant que représente le Web, mais elles sont également un support de coordination avec d'autres internautes. Les tags apparaissent comme des appuis conventionnels qui permettent decoordonner les actions au sein de collectifs à géométrie variable, plus ou moins étendus et identifiés, dont les membres partagent des centres d’intérêts et un vocabulaire commun. A partir d'une approche socio-technique nous étudions le couplage entre conception et usage de ces dispositifs, et montrons que le tagging propose une voie alternative, encore enconstruction, aux politiques existantes d'architecture et d’accessibilité des ressources du Web / This research proposes an anlysis of tagging systems uses on the Web. Tagging is not a simple personnal tool of web ressources categorization but classifications emerging from free tags indexation, named folksonomies, allow Internet users to create physical and interpretative supports which produce new forms of social navigation. Those tagging networks give the opportunity to Internet users to navigate and to act in the complex and abundant Web universe, but they are also coordination supports with other Internet users. Tags appear as conventionnal supports which allow coordination of actions in variable-geometry collectives. In those more or less identified and large collectives, members share common vocabulary and interests. Based on a socio-technical approach, we study coupling between conception and uses of tagging systems. We explain that tagging proposes an under construction and alternative way to architecture and accessibility politics of the Web ressources

Découverte et analyse des communautés implicites par une approche sémantique en ligne : l'outil WebTribe / Discovery and analysis of implicit communities using an online semantic approach : the WebTribe toolLeprovost, Damien 30 November 2012 (has links)
Avec l’essor du Web 2.0 et des technologies collaboratives qui y sont rattachées,le Web est aujourd’hui devenu une vaste plate-forme d’échanges entre internautes.La majeure partie des sites Web sont actuellement soit dédiés aux interactionssociales de leurs utilisateurs, soit proposent des outils pour développer ces interactions.Nos travaux portent sur la compréhension de ces échanges, ainsi que desstructures communautaires qui en découlent, au moyen d’une approche sémantique.Pour répondre aux besoins de compréhension propres aux analystes de siteWeb et autres gestionnaires de communautés, nous analysons ces structures communautairespour en extraire des caractéristiques essentielles comme leurs centresthématiques et contributeurs centraux. Notre analyse sémantique s’appuie notammentsur des ontologies légères de référence pour définir plusieurs nouvelles métriques,comme la centralité sémantique temporelle et la probabilité de propagationsémantique. Nous employons une approche « en ligne » afin de suivre l’activitéutilisateur en temps réel, au sein de notre outil d’analyse communautaire Web-Tribe. Nous avons implémenté et testé nos méthodes sur des données extraites desystèmes réels de communication sociale sur le Web / With the rise of Web 2.0 and collaborative technologies that are attached to,the Web has now become a broad platform of exchanges between users. The majorityof websites is now dedicated to social interactions of their users, or offerstools to develop these interactions. Our work focuses on the understanding of theseexchanges, as well as emerging community structures arising, through a semanticapproach. To meet the needs of web analysts, we analyze these community structuresto identify their essential characteristics as their thematic centers and centralcontributors. Our semantic analysis is mainly based on reference light ontologiesto define several new metrics such as the temporal semantic centrality and thesemantic propagation probability. We employ an online approach to monitor useractivity in real time in our community analysis tool WebTribe. We have implementedand tested our methods on real data from social communication systemson the Web

Gruppenorientiertes Requirement Engineering auf der Basis von Lotus NotesLiskowsky , R., Pjater, R., Steifer, H. 23 September 2016 (has links) (PDF)
Aus der Zusammenfassung:
"Alle Projektarbeit insbesondere zur Schaffung verteilter Gemeinschaften, die mit neuen multimedialen Informationen arbeiten, beginnt mit einer tiefgründigen Anforderungsanalyse. Wenn diese frühe Phase der Softwareentwicklung ebenso von einem verteilt arbeitendem Team, bestehend aus Auftraggebern, Auftragnehmern, Systemanalytikern, Endnutzern u.a., durchgeführt wird, sprechen wir von einem gruppenorientierten Requirement Engineering. Gegenwärtig liegen für dessen rechentechnische Unterstützung noch keine befriedigenden Lösungen vor."

Environnements numériques et PME : figures du chaos et nouveaux usages / Digital environments and SMEs : figures of chaos and new usesChoquet, Isabelle 04 June 2015 (has links)
La « révolution » du web 2.0 s’est-elle imposée dans les PME ? La mise en réseau, porté par le web 2.0 qui met l’utilisateur au centre des processus de l’entreprise, a–t’elle opéré un changement de paradigme communicationnel au sens de Kuhn ? Sur fonds d’une société de plus en plus fluide, inscrite dans l’incertitude et la complexité, cette thèse s’intéresse à la question des ajustements transversaux en lien avec le web 2.0 et à leur prise en compte par les PME. Ce dernier peut être vu comme source de désordres dans l’organisation et la PME sera tentée de vouloir les réguler. Néanmoins, certaines PME choisiront de s’en servir comme d’un tremplin. Elles vont à la fois construire sur des compétences existantes et améliorer l’efficience de l’entreprise (activité d’exploitation) mais également explorer des champs totalement nouveaux (activité d’exploration) dont l’intelligence collective et le crowdsourcing sont des exemples. Les outils du web 2.0 indiquent le passage d’une technologie « outils » considérée comme stable vers une technologie « sociale » caractérisée par l’instabilité. Le web 2.0 a un effet de catalyseur qui suscite et facilite à la fois les ajustements transversaux, il peut se concevoir comme un levier de pilotage vers une organisation plus centrée sur les individus et les groupes. Ceci pose un certain nombre de défis aux PME. L’éclairage des sciences du chaos et de la complexité semble une piste intéressante pour comprendre cet équilibre à atteindre entre ordre et désordre. Cette thèse a un ancrage interdisciplinaire et montre l’intérêt de croiser les sciences de gestion et les sciences de l’information et de la communication lorsque ces disciplines sont appelées à prendre en compte la complexité des rapports transversaux mais aussi de co-construction entre consom’acteurs et PME. La recherche s’appuie entre autres, sur un terrain applicatif de 93 PME, auditées entre 2010 et 2014. / Is the revolution of the so-called Web 2.0 a real success for the SMEs? Do we really see a change of the communication paradigm (following Kuhn’s meaning) due to the arrival of the networks that put the individual at the centre of the organization processes? Within the framework of a “fluid society” characterised by uncertainty and complexity, this thesis focuses on the issue of internal and external adjustments in connection with the Web 2.0 within SMEs. These adjustments may be a source of disorder within the organization and SMEs would try to regulate them. Nevertheless, some SMEs will choose to use them as a springboard. They will build on existing skills, improve the efficiency of the company (operating activity) and also explore completely new fields (exploration activity) like collective intelligence and crowdsourcing. The web 2.0 indicates the passage of a "tools" technology considered as stable to a "social" technology characterized by instability. The Web 2.0 has a catalytic effect that encourages and facilitates transversal adjustments. It could be seen as a way to transform the organization in order to become more focused on individuals and groups. But it also brings a number of challenges for SMEs. Using the concepts of chaos and complexity was an interesting way to understand this balance to be attained between order and disorder. This thesis is interdisciplinary by objective. It intends to show the interest of using together theories, literature and fields coming from management, information science and communication when these disciplines are required to take into account the complexity of relationships but also co-construction between prosumers and SMEs, and management and employees. The research will be based inter alia on a total of 93 SMEs, audited by the author between 2010 and 2014.

Previous issue date: 2015-02-23 / Knowledge has become a valuable intangible asset that can help project management, in a way that known errors activities can be avoided and processes that have worked can be repeated and hence, integrated into organization. However, problems associated with the management of lessons learned are pervasive in organizations, including project members claiming lack of time to perform activities of lessons learned management, prioritizing other activities. When lessons learned activities are carried out, it was identified inconsistencies in the process of capture of tacit knowledge because team members often do not feel comfortable in sharing their knowledge or report their failures. Additionally, when the capture occurs, the project members find it difficult to record the information because the IT tools currently available to support the process of lessons learned, appear inefficient, especially in terms of search engines. Project management guides used in organizations (e.g. PMBoK-PMI and ICB-IPMA) do not have processes or specific activities for knowledge management and lessons learned in projects. Therefore, it was identified the need for the treatment of lessons learned in organizations and specifically in Information Technology (IT) and Information Systems (IS) projects. This dissertation aims to: 1. Develop a model of adoption of IT 2.0 tools to assist IT/IS project managers in the lessons learned management and 2. Validate the proposed model by reviewing the model with experts in projects. We used mixed methods as paradigm and method in this research. Ten interviews and 183 answers of the questionnaire were used to answer the research question "how lessons learned can be managed with the support of IT 2.0 tools in IT/IS projects?” As a result, it was generated the Target 2.0 model, which includes the following lessons learned management processes: raising awareness, collect/verify, store/disseminate and reuse processes. They are supported by technologies as Wikis, Social Networks, Blogs, Really Simple Syndication (RSS) and Web Office. Regards the contribution to theory, this dissertation is of explanatory and predictive type, has incremental originality and scientific and practical use. For the contribution to practice the study assists the project team to implement lessons learned activities suggesting tools and processes. We conclude that the lessons learned can be managed through lessons learned processes performed in any phase of the project. The suggested tools facilitate the exchange of experiences and collaboration and the Target 2.0 model covers processes, technology and people, aspects that can ensure better results when aligned with the strategy and the structure of the organization. / O conhecimento é um recurso intangível valioso, que auxilia a gestão de projetos, de forma que erros conhecidos sejam evitados e atividades e processos que deram certo sejam repetidos e, consequentemente, integrados à organização. Entretanto, problemas associados à gestão de lições aprendidas são pervasivos nas organizações, o que inclui membros do projeto que alegam falta de tempo para desempenhar atividades de gestão de lições aprendidas, priorizando outras atividades. Por outro lado, quando a gestão de lições aprendidas é realizada, identificam-se inconsistências no processo de captura de conhecimento tácito, pois os membros do projeto, muitas vezes, não se sentem à vontade em compartilhar o conhecimento criado ou em reportar suas falhas. Além disso, quando a captura ocorre, os membros do projeto encontram barreiras para registrar as informações, pois as ferramentas de Tecnologia da Informação (TI) que têm suportado a gestão de lições aprendidas mostram-se ineficientes, principalmente os seus mecanismos de busca. Os guias de gerenciamento de projetos utilizados nas organizações (e.g. PMBoK-PMI e ICB-IPMA) não possuem processos ou tratativas para gestão de lições aprendidas em projetos. Neste contexto, identificou-se a necessidade de investigar a gestão de lições aprendidas em projetos de TI e Sistemas de Informação (SI). Esta dissertação tem como objetivos: 1. desenvolver um modelo de adoção de TI 2.0 para auxiliar os gestores de projetos de TI/SI no tratamento das lições aprendidas e 2. validar o modelo proposto com especialistas em projetos. Para atingir estes objetivos, os métodos mistos foram usados como paradigma e método de pesquisa. Dez entrevistas e 183 respostas válidas ao questionário foram usadas para responder a questão de pesquisa “como as lições aprendidas podem ser geridas com o apoio de ferramentas de TI 2.0 em projetos de TI/SI?". Como resultado foi gerado o modelo Target 2.0 que contempla os seguintes processos de gestão de lições aprendidas: conscientização, coleta/verificação, armazenamento/disseminação e reutilização. Esses processos são suportados pelas tecnologias Wikis, Redes Sociais, Blogues, Office na Web e Really Simple Syndication (RSS). Quanto à contribuição para a teoria, o modelo Target 2.0 é do tipo explicativo e preditivo, possui originalidade incremental e utilidade científica e prática. Para a contribuição para a prática o estudo auxilia a equipe de projetos a executar as atividades de lições aprendidas sugerindo ferramentas e processos. Conclui-se que as lições aprendidas podem ser geridas através de processos de lições aprendidas realizados em qualquer fase do projeto. As ferramentas incorporadas ao Target 2.0 facilitam a troca de experiências e a colaboração e este modelo cobre os pilares de processos, tecnologia e pessoas, aspectos que podem garantir melhores resultados quando em conjunto são alinhados com a estratégia e a estrutura da organização.

Previous issue date: 2017-03-02 / A new composite of surgical governance methods, tools and mechanisms to meet as new needs of the modern world (Levitt, 2011). IT, technologies, technology, the growth of the Internet and collaborative information technologies (IT), ie Web 2.0 technologies. A new reality has a great base and participation of human resources (HR), being able to self-manage and to be creative (McDonald, 2011). In this context, the following research question is asked: "What are the individual competencies of human resources without a 2.0 project management paradigm in the area of Information Technology?". With the objective of analyzing how it presented itself as individual competences of the human resources without paradigm of GP 2.0 in the area of IT. For that, the qualitative method with focus group and individual interviews was used to answer as five propositions raised in this study. We conclude that the more volatile environment, in changes, caused the GP to undergo changes to meet as needs. Collaborative technology directly influences the current administration as well as the influence of human resources that create an internet and methods. It still exists in the literature, as raised throughout the part in the lab, project management 2.0 has already been under development in the practical field for years. Much of the competency identified not GP 1.0 remains unchanged and other competencies gain new forms. Through the exploratory study has been lifted a list of competencies contained in our sets of competencies, communication, interpersonal and business and project management 2.0 business. This study contributed as research areas of HR competencies and project management, with an exploratory research of HR competencies in GP 2.0. It was also sought to contribute to the practical field, that is, to the notions of process distribution in the processes of recruitment and maintenance of the human resources that work in contemporary projects, through the evaluation framework of competencies. / Um novo composto de métodos, ferramentas e mecanismos de governança surgiu para atender as novas necessidades do mundo moderno (Levitt, 2011). Apresenta-se, portanto, o gerenciamento de projetos contemporâneo com essas novas tendências devido a globalização, o crescimento da internet e as inserções das tecnologias de informação (TI) colaborativas, ou seja, das tecnologias da Web 2.0. Nesta nova realidade tem-se uma maior cooperação e participação dos recursos humanos (RH), sendo que esses se destacam por, cada vez mais, serem capazes de se autogerenciar e de serem criativos (McDonald, 2011). Neste contexto, busca-se responder a seguinte questão de pesquisa “Quais são as competências individuais no paradigma de gerenciamento de projetos 2.0 na área de Tecnologia da Informação?”. Com o objetivo de analisar como se apresentam as competências individuais no paradigma de GP 2.0 na área de TI. Para tanto foi utilizado o método qualitativo com realização de grupo focal e de entrevistas individuais para responder as cinco proposições levantadas neste estudo. Conclui-se que o ambiente mais volátil, em constantes mudanças, fez com que o GP sofresse mudanças para atender as necessidades. A tecnologia colaborativa influencia diretamente na gestão atual, bem como influencia os recursos humanos que cresceram com a internet e os métodos ágeis. Embora ainda recente na literatura, como levantado ao longo da parte exploratória neste trabalho, o gerenciamento de projetos 2.0 já está em desenvolvimento no campo prático há anos. Boa parte das competências identificadas no GP 1.0 permanece inalterada e outras competências ganham novas formas. Através do estudo exploratório foi levantada uma lista das habilidades contidas nos conjuntos de competências pessoais, de comunicação, interpessoal e de negócio e negócio do gerenciamento de projetos 2.0. Este estudo contribuiu com as áreas de pesquisa de competências de RH e de gerenciamento de projetos, com uma pesquisa exploratória das competências de RH no GP 2.0. Buscou-se contribuir também com o âmbito prático, ou seja, com as organizações no que tange as avaliações de competências nos processos de recrutamento e na manutenção dos recursos humanos que atuam nos projetos contemporâneos, através do framework avaliativo de competências.

Previous issue date: 2017-02-23 / O atual ambiente competitivo leva as empresas a procurarem soluções para melhorar o desempenho de seus projetos. Nesse contexto, a adoção de ferramentas para suportar a gestão desses projetos é essencial. Mídias sociais como wikis, blogues e microblogues, surgiram para apresentar novas formas de facilitar as atividades de gerenciamento de projetos (GP), para que possam contribuir para o sucesso do projeto. No entanto, as empresas subexploram o efetivo uso integrado de tais ferramentas como suporte no GP. Os gerentes de projeto enfrentam alguns desafios, tais como falta de conhecimento das ferramentas e, onde e como armazenar dados para a utilização eficaz destas tecnologias. O objetivo desta pesquisa é desenvolver um framework prescritivo para orientar o uso integrado de mídias sociais para apoiar o GP. Esta pesquisa exploratória e qualitativa foi conduzida sob a epistemologia construtivista social e hermenêutica. Primeiro, eu realizei uma revisão de literatura utilizando uma abordagem hermenêutica. Como o uso de mídias sociais no GP ainda é um tema emergente, existem poucos estudos empíricos sobre o assunto. Para superar esse problema, entrevistei gerentes de projetos e realizei um grupo focal exploratório com participantes que usavam mídias sociais em sua profissão. Analisei os dados usando Grounded Theory Methodology (GTM) da Escola Charmaz, versão construtivista e mais recente do Grounded Theory. Finalmente, realizei um grupo focal confirmatório para validar o framework. Os resultados mostram que o entendimento dos recursos de cada mídia social, juntamente com ações de conscientização do uso de um conjunto comum de ferramentas, representa um instrumento poderoso para a condução de projetos nas organizações. Foram identificadas quatro categorias de uso das mídias sociais: comunicação, controle, disseminação e repositório. Considerando que a maioria das pesquisas explora o uso de uma única ferramenta ou seu uso isolado, esta pesquisa adiciona à literatura o SOME4PM - um framework prescritivo de uso integrado de mídias sociais para GP. Como contribuição prática, apresenta uma visão do framework contendo exemplos de mídias sociais atuais para ajudar as organizações na escolha do conjunto dessas mídias que melhor se encaixa em suas necessidades. Além disso, fornece cenários e recomendações para o uso efetivo do SOME4PM nas organizações. Assim, os gerentes de projeto têm uma visão ampla sobre como as mídias sociais estão sendo usadas e como elas podem ser integradas para apoiar o GP. / The current competitive environment drives companies to seek solutions to improve the performance of their projects. In this context, the adoption of tools to support the management of these projects is essential. Social media such as wikis, blogs and microblogs, have emerged to present innovative ways to facilitate project management (PM) activities so that they can contribute to the success of the projects. However, companies underexplore the effective integrated use of such tools as a support in PM. Project managers face some challenges, such as lack of knowledge of the tools and, where and how to store data for the effective use of these technologies. The objective of this research is to develop a prescriptive framework to guide the integrated use of social media to support PM. This exploratory and qualitative research was conducted under the social constructivist epistemology and hermeneutics. First, I performed a literature review using a hermeneutic approach. As the use of social media in PM is still an emerging theme, there are few empirical studies on the subject. To overcome this problem, I interviewed project managers and I led an exploratory focus group with participants who use social media in their profession. I analyzed the data using Grounded Theory Methodology (GTM) of the Charmaz, a constructivist and the later version of Grounded Theory. Finally, I led a confirmatory focus group to validate the framework. Findings show the understanding of the resources of each social media, along with actions to raise awareness of the use of a common set of tools, represent a powerful instrument for conducting projects in organizations. Four categories of the use of social media were identified: communication, control, dissemination and repository. Considering that most research explores the use of a single tool or their use isolated, this research adds to the literature SOME4PM - a prescriptive framework of integrated use of social media in PM. As a practical contribution, it presents a view of framework contains examples of currently social media to help organizations choice the set of social media that better fit in their needs. Furthermore, it provides scenarios and recommendations for the effective use of SOME4PM in organizations. Hence, project managers have a broad vision on how social media are being used and how they can be integrated to support PM.

Componentes para interoperabilidade entre redes sociais na Web 2.0 / Components for interoperability among Web 2.0 social networksCarlos Leonardo Herrera Muñoz 19 March 2013 (has links)
Nos últimos anos, as redes sociais na Web 2.0 vêm ganhando cada vez mais importância para trabalhar e compartilhar ideias. As redes sociais armazenam informações do usuário, como preferências, experiência profissional, dados pessoais e com quem o usuário interage. Essas informações são úteis para diversos fins, como oferecer produtos e serviços personalizados. Com a aparição de cada vez mais redes sociais, surgem problemas como a duplicação de perfis de usuários. Atualmente há algumas técnicas para interoperar as redes sociais, como serviços de autenticação única ou representação padrão para compartilhamento de dados. O objetivo deste trabalho foi realizar um estudo dessas técnicas e tecnologias disponíveis, implementá-las por meio de componentes do Groupware Workbench, e implantar e avaliar os componentes desenvolvidos na rede social Arquigrafia. A avaliação dos componentes foi realizada por meio dos aspectos e questões propostos pelo projeto DataPortability. A avaliação mostrou que as questões diretamente relacionadas com a interoperabilidade técnica e semântica foram respondidas. / In recent years, the importance of social networks for working and sharing ideas increased. Social networks store information such as user preferences, professional experience, personal data, and information about with whom the user interacts. This kind of information is useful for many purposes, such as offering personalized products and services. With the appearance of more social networks, problems as duplication of user profiles arise. Currently, there are some techniques for interoperating social networks, such as single authentication services and standard representation for data sharing. The objective of this work was to study techniques and technologies available, implement them as Groupware Workbench components, and deploy and evaluate the components in the social network Arquigrafia. The evaluation of the components was based on the DataPortability project. Issues related to technical and semantic interoperability have been successfully addressed.
