Initially, we aim to understand, through the archaeological and genealogical Foucault s methods, the conditions of possibility of two different classification procedures, one traditional and other contemporary. For doing this, a contextualization of the field of knowledge called Librarianship and Information Science will be presented, as well as the models of information organization used, and this field s tendencies. In sequence, considering the theoretical categories derived from the works of Bakhtin and Foucault, we will analyze different forms of classification of knowledge and of language concepts that underlie them. Some of the results indicate that there is a new form of power implied in the social practice of folksonomy, understood as one collaborative tool to organize the information in the Web 2.0, in which the subjects themselves act in the regulation of discourse and in the creation of new concepts. The analytical reflections illustrate that the subjects act in a responsive way on the internet by manipulating linguistic features through the creation of tags related to different semantic universes. We also intended to locate points of resistance focusing on the linguistic and discursive practices of folksonomy as a locus of social change. The Web 2.0 works based on a dynamics of incitement and pleasure which reinforces the flow of information and online relationships, thus, folksonomy works like a type of social network which allows relationships among the subjects with the same interests through the use of a creative, collaborative and personalized way of content organization. Regarding the current trends of studies in the field of Librarianship and Information Science, folksonomy has functioned as a tool to assist the approaches that take into account the users and context of use of information in documentary languages. / Esta pesquisa trata dos modelos de organização e classificação das informações na área da Biblioteconomia e Ciência da Informação, priorizando uma forma mais dialógica de organização das informações, a folksonomia. Inicialmente, trata-se de compreender, por meio dos métodos arqueológico e genealógico de Foucault, as condições de possibilidade de dois tipos diferentes de procedimentos de classificação, um tradicional e outro contemporâneo. Para tanto, será feita uma contextualização do campo de saber da Biblioteconomia e Ciência da Informação, dos modelos de organização das informações utilizados por ele, e das tendências de estudo neste campo. Na sequência, a partir de categorias teóricas oriundas dos trabalhos de Bakhtin e de Foucault, pretendese analisar diferentes formas de classificação do conhecimento e as concepções de língua subjacentes a eles. Alguns resultados indicam que há uma nova forma de circulação do poder na prática da folksonomia, tomada como uma ferramenta colaborativa de organização de informações da Web 2.0, em que os próprios sujeitos funcionam como instâncias de regulamentação de discursos e criação de novos conceitos. As reflexões analíticas ilustram a possibilidade da ação responsiva dos sujeitos na Internet através da manipulação linguística na criação de tags vinculadas a universos semânticos diferenciados. Tentou-se localizar pontos de resistências focalizando as práticas linguístico-discursivas da folksonomia como lócus de mudanças sociais. A Web 2.0 funciona segundo uma dinâmica do poder de incitação à circulação e ao relacionamento online, assim, a folksonomia funciona também como um tipo de rede social que possibilita relacionamentos entre sujeitos com os mesmos interesses, além de uma organização de conteúdos criativa, personalizada e colaborativa. A respeito das tendências atuais de estudos do campo da Biblioteconomia e Ciência da Informação, a folksonomia tem funcionado como uma ferramenta de auxílio nas abordagens que levam em consideração o sujeito e o contexto de uso da informação na utilização de linguagens documentárias.

No. of bitstreams: 1 AMARAL_Anderson_2014.pdf: 3835882 bytes, checksum: 2fdc6c0cc705277a06fbcce246dd4b79 (MD5) Previous issue date: 2014-12-03 / Aspects of social tagging have been studied in the last years aiming at addressing concepts, applicability and techniques related to the generation and management of tags as key elements for the resource research and classification. Social tagging has been recognized as an important alternative for the description of resources available on the Web. Concerning on the rapid growth of resources and their information on the Web, it has become increasingly difficult to find and organize such massive data by traditional methods as based on directories classification. The process of social tagging has been investigated to improve the cataloging of resources, being recommendation algorithms of tags, visualization techniques and automatic generation of tags, among others have been explored for this purpose. Within the e-learning context, the social tagging may assist on building of metadata of learning objects. Thus, all the advantages linked to this model of resources organization, has emerged as solutions for e-learning systems. The main contribuition of a teaching-learning environment is the creation, storing and maintenance of the catalog of learning resources that can be checked and updated continuously. This work proposes a tags recommendation system, improving the process of cataloguing of learning resources on the web. Three experiments were carried out with technician students of a informatics course to validate the proposal: the first one examined the social tagging activity without using the tag recommendation system; the second one was conducted to evaluate the tagging activity, but including the tags recommendation system; and the third one verified the students navigation from the tagged resources created from the first and the second experiment, in order to check that the support of the recommendation was effective in the descriptor vocabulary of the resource. / Aspectos da marca¸c ao social t em sido estudados nos ´ultimos anos com o objetivo de abordar conceitos, aplicabilidade e t´ecnicas relacionadas `a gera¸c ao e gest ao de tags como elementos-chave para a pesquisa de recursos e classifica¸c ao.

No que diz respeito sobre o r´apido crescimento dos recursos e suas informa¸c oes na Web, tornou-se cada vez mais dif´ıcil de encontrar e organizar essa grande massa de dados por m´etodos tradicionais com base na classifica¸c ao em diret´orios. O processo de marca¸c ao social tem sido investigado para melhorar a cataloga¸c ao de recursos, sendo que estrat´egias como algoritmos de recomenda¸c ao de tags, t´ecnicas de visualiza¸c ao e gera¸c ao autom´atica de tags, entre outras foram exploradas para esta finalidade.

Tr es experimentos foram realizados com os alunos de um curso t´ecnico de inform´atica para validar a proposta: o primeiro examinou a atividade de marca¸c ao social sem usar o sistema de recomenda¸c ao de tags; o segundo foi realizado para avaliar a atividade de marca¸c ao, mas incluindo o sistema de recomenda¸c ao de tags; e o terceiro verificou a navega¸c ao dos estudantes a partir dos recursos marcados e criados a partir do primeiro e do segundo experimentos, a fim de verificar que o apoio da recomenda¸c ao foi eficaz no vocabul´ario descritor dos recursos.

The paper explores the rise of digital cartography and subsequently location-based services, using Foursquare as case study. In fact, the rise of smartphones and wireless technologies have made Internet ubiquitous and online services accessible from anywhere. In this context, I address the changes in carthography and how it has been remediated on digital media. I then analyze some of the developments brought by the Web 2.0 in relation to location-based services, especially user-generated content, social networking websites, tagging and geotagging. Foursquare's content is created by its users, therefore enabling them to map the(ir) world. Foursquare remediates maps and travel guides, and it uses game dynamics to foster usage and sharing. The concept of online identity-building will be also addressed in relation to the sharing of one's location and how these factors enhance performative aspects. I conclude by investigating how the geotagging tendency on social networking platforms could be as well seen as a tool for enhancing user-generated surveillance.

The web has evolved much through the years. From being a place where author and reader were clearly distinguished, it now invites everyone to take part in the development of both content and technology. Social services are central in what is called Web 2.0. Wikis, blogs and folksonomies are all examples of how the users and their communities are key to the development of services. Collaborative writing, tags and API:s are central. Social services are given an extra dimension through integration. The purpose of this study was to investigate whether it was possible to integrate an encyclopedia with a photosharing service. The issue was whether it was possible to find relevant images to the article they were connected to. The method for examining the issue was to create a service which functions was investigated through user tests. Wickrpedia was created, which is an integration of Wikipedia and Flickr. Wikipedia is an encyclopedia in the shape of a wiki, while Flickr is used to store, organize and share photos. The result shows that the images added someting to the encyclopedia; it became more entertaining and pleasant and the users’ knowledge was increased. The relevance of the images was good. The service can and should be improved. The conclusion is still that the service worked well and was seen as an improvement by the users. / Webben har förändrats mycket de senaste åren. Från att tidigare haft en tydlig uppdelning mellan läsare och författare inbjuds nu alla att delta i utvecklingen av både innehåll och teknik. Sociala tjänster är det centrala i det som benämns Web 2.0. Wikis, bloggar och folksonomies är alla exempel på hur användarna och deras gemenskap är nyckeln till utveckling av tjänster. Kollaborativt skrivande, taggar och API:er är centrala. Sociala tjänster får en ytterligare dimension genom integrering. Denna studies syfte var att utreda hur det gick att integrera ett uppslagsverk med en fotodelningstjänst. Frågan är om det gick att göra på ett sådant sätt att bilderna hade relevans för de artiklar de kopplades till. Metoden för att utreda frågan var att skapa en tjänst vars funktion undersöktes med hjälp av användartester. Wickrpedia skapades, vilket är en intregrering av Wikipedia och Flickr. Wikipedia är en encyklopedi i form av en wiki, medan Flickr används för att förvara, organisera och dela med sig av bilder. Resultatet visar att bilderna tillförde något till uppslagsverket; det blev roligare och trevligare och användarna fick en ökad kunskap. Relevansen hos bilderna var god. Tjänsten har brister, och den går att vidareutveckla. Slutsatsen var ändå att tjänsten fungerade och var en förbättring för användarna.

L’organisation des connaissances est une discipline investie par des bibliothécaires, documentalistes, archivistes spécialistes de l’information, informaticiens et tous professionnels de documents. Elle englobe toutes activités, études et recherches qui élaborent et traitent les processus d’organisation et de présentation des ressources documentaires utiles dans une organisation. Dans ce contexte, le projet ANR Miipa-Doc a pour objectifs d’explorer des nouvelles méthodes d’indexation ascendantes, en utilisant des termes descripteurs formulés par les individus plutôt que choisis parmi une liste préétablie, pour l’organisation des contenus documentaires complexes au sein des entreprises de large taille, et concevoir l’architecture logicielle correspondante.Dans ce projet notre contribution consiste à gérer l’hétérogénéité d’un système d’information d’organisation des contenus documentaires, basé sur une approche orientée métier et un SOC (système d’organisation des connaissances) folksonomique à facette. Nous proposons dans cette gestion une approche incrémentale dirigée par les modèles, issue de l’IDM (ingénierie dirigée par les modèles), basée sur des méta-modèles pour garantir l’aspect d’évolutivité. Après l’implémentation du prototype HyperTaging qui met en place ces deux approches, nous proposons un processus d’évaluation permet de positionner ce prototype et tous SI de classification documentaire dans l’environnement des ECM, en se basant sur des critères d’évaluation fins et particuliers. / The knowledge organization is invested by librarians, archivists, information specialists, IT professionals and all discipline of document. It includes all activities, studies and research which develop and treat organization process and presentation of relevant information resources in an organization. In this context the Miipa-Doc project aims to explore new ascendants indexing methods, using descriptors made by individuals rather than selected given list for complex contained in the organization document, in large size companies, and design the corresponding software architecture.Our contribution in this project is to manage the heterogeneity of an information system of document organization, based on a business-oriented approach and a KOS (knowledge organization system) of folksonomy facet. We propose an incremental approach this management model driven, outcome of MDE (Model Driven Engineering), based on meta-models to ensure scalability appearance. After implementing the HyperTaging prototype, that implements both approaches, we propose an evaluation process used to position the prototype and all IS of documentary classification in the environment of ECM based on purposes of delicate and particular evaluation criteria.

Les systèmes de recommandation ont acquis une certaine popularité parmi les chercheurs, où de nombreuses approches ont été proposées dans la littérature. Les utilisateurs des folksonomies partagent des items (e.g., livres, films, sites web, etc.) en les annotant avec des tags librement choisis. Avec l'essor du Web 2.0, les utilisateurs sont devenus les principaux acteurs du système étant donné qu'ils sont à la fois les contributeurs et créateurs de l'information. Ainsi, il est important de répondre à leurs besoins en leur proposant une recommandation plus ciblée. Pour ce faire, nous considérons une nouvelle dimension dans une folksonomie classiquement composée de trois dimensions <utilisateurs,tags,ressources> et nous proposons une approche afin de regrouper les utilisateurs ayant des intérêts proches à travers des structures appelées concepts quadratiques. Ensuite, nous utilisons ces structures afin de proposer un nouveau système personnalisé de recommandation. Nous évaluons nos approches sur divers jeux de données du monde réel. Ces expérimentations ont démontré de bons résultats en termes de précision et de rappel ainsi qu'une bonne évaluation sociale. De plus, nous étudions quelques unes des métriques utilisées pour évaluer le systèmes de recommandations, comme la couverture, la diversité, l'adaptivité, la sérendipité ou encore la scalabilité. Par ailleurs, nous menons une étude de cas sur quelques utilisateurs comme complément à notre évaluation afin d'avoir l'avis des utilisateurs sur notre système. Enfin, nous proposons un nouvel algorithme qui permet de mettre à jour un ensemble de concepts triadiques sans avoir à re-scanner l'entière folksonomie. Les premiers résultats comparant les performances de notre proposition par rapport au redémarrage du processus d'extraction des concepts triadiques sur quatre jeux de données du monde réel a démontré son efficacité. / Recommender systems are now popular both commercially as well as within the research community, where many approaches have been suggested for providing recommendations. Folksonomies' users are sharing items (e.g., movies, books, bookmarks, etc.) by annotating them with freely chosen tags. Within the Web 2.0 age, users become the core of the system since they are both the contributors and the creators of the information. In this respect, it is of paramount importance to match their needs for providing a more targeted recommendation. For such purpose, we consider a new dimension in a folksonomy classically composed of three dimensions <users,tags,resources> and propose an approach to group users with close interests through quadratic concepts. Then, we use such structures in order to propose our personalized recommendation system of users, tags and resources. We carried out extensive experiments on two real-life datasets, i.e., MovieLens and BookCrossing which highlight good results in terms of precision and recall as well as a promising social evaluation. Moreover, we study some of the key assessment metrics namely coverage, diversity, adaptivity, serendipity and scalability. In addition, we conduct a user study as a valuable complement to our evaluation in order to get further insights. Finally, we propose a new algorithm that aims to maintain a set of triadic concepts without the re-scan of the whole folksonomy. The first results comparing the performances of our proposition andthe running from scratch the whole process over four real-life datasets show its efficiency.

Suite à l’avènement du Web 2.0, le rôle de l’internaute s’est vu modifier, passant de consommateur passif à acteur à part entière. De nouvelles fonctionnalités ont vu le jour augmentant considérablement les possibilités d’interaction avec le système. Parmi celles-ci, le collaborative tagging permet à l’utilisateur de décrire l’information en ligne par l’attribution de mots-clés (ou tags), la particularité étant que ces tags ne sont pas uniquement accessibles aux tagueurs eux-mêmes mais à l’ensemble des internautes. L’octroi de tags à une ressource lui offre donc de multiples chemins d’accès exploitables par la communauté internet tout entière. Régulièrement comparé à l’indexation « professionnelle », le collaborative tagging soulève une question essentielle :cette nouvelle pratique contribue-t-elle favorablement à la description et, par extension, à la recherche d’informations sur internet ?<p>Tous les types d’informations ne pouvant être étudiés, la présente dissertation se focalise sur l’information médicale scientifique utilisée par les médecins dans le cadre de leur pratique professionnelle. Elle propose, dans un premier temps, de mesurer le potentiel des tags assignés dans deux systèmes de collaborative tagging (Delicious et CiteULike) à décrire l’information en les comparant à des descripteurs attribués par des professionnels de l’information pour un même échantillon de ressources. La comparaison a mis en lumière l’exploitabilité des tags en termes de dispositifs de recherche d’informations mais a néanmoins révélé des faiblesses indéniables par rapport à une indexation réalisée par des professionnels à l’aide d’un langage contrôlé.<p>Dans un second temps, la dissertation s’est intéressée aux utilisateurs finaux en quête d’informations, c’est-à-dire les médecins, afin de déterminer dans quelle mesure un système de collaborative tagging (CiteULike) peut assister ces derniers lors de leur recherche d’informations scientifiques. Pour ce faire, des entretiens individuels combinant interview semi-structurée et expérimentation ont été organisés avec une vingtaine de médecins. Ils ont fourni des indications riches et variées quant à leur adoption effective ou potentielle d’un système de collaborative tagging dans le cadre de leurs pratiques informationnelles courantes.<p>Enfin, cette dissertation se propose d’aller au-delà de l’étude des tags et du phénomène de collaborative tagging dans son ensemble. Elle s’intéresse également aux compétences informationnelles des médecins observés en vue d’alimenter la réflexion sur les formations qui leur sont dispensées tout au long de leurs études mais également durant leur parcours professionnel. / Doctorat en Information et communication / info:eu-repo/semantics/nonPublished
