Indexation de documents pédagogiques : Fusionner les approches du web sémantique et du web participatif

Abstract : Current ways for Web indexing are not sufficient for learning resources. Indeed, automatic indexing, e.g. Google, can hardly raise above the syntaxical level of contents while indexing by human experts implies high costs. But, recent approaches like Semantic Web and Participative Web (Web 2.0) offer promising solutions. A first part of our works concerns the study of Semantic Web applied to learning resources. We explore possibilities of reasonings applied to educational ontologies. A second part is about the study of functionalities on participative websites making easier the adding of content and metadata by visitors. Then we propose a model of participative website adapted to communities of teachers. Nevertheless, Semantic Web and Participative Web are often opposed. Formal ontologies generally produced by experts are opposed to heterogeneous tags added by numerous users with various profiles. In a third part, we propose a model melting Semantic and Participative. The goal of this model is to help developping applications for sharing resources into communities of practice. It is based on a Progressive and Multi-points of view Indexing in which: - users progressively structure metadata, to finally allow semantic reasonings by computers; - users progressively collaborate, to finally allow a shared vision of the domain by humans. This model is implemented into a social bookmarking tool, called SemanticScuttle, offering original features like tags structured by relations of inclusion and synonymy, or wiki spaces to describe tags. The tool was developped and tested with librarians in sociology during several months. Finally, our works allow us to formulate hypotheses about a social and technical model supporting sharing between teachers. They also contribute to models melting different indexing solutions: automatic or by humans, including experts or simple users, based on structured models (e.g. ontologies) or on flexible metadata (e.g. tags).
