Verifying Semantic Graphs With the Model Checker SPIN
2011
International audience; The most frequently used language to represent the semantic graphs is the RDF (W3C standard for meta-modeling). The construction of semantic graphs is a source of numerous errors of interpretation. The processing of large semantic graphs is a limit to the use of semantics in current information systems. The work presented in this paper is part of a new research at the border between two areas: the semantic web and the model checking. For this, we developed a tool, RDF2SPIN, which converts RDF graphs into SPIN language. This conversion aims checking the semantic graphs with the model checker SPIN in order to verify the consistency of the data. To illustrate our propos…
Découverte de communautés par analyse des usages
2010
National audience; Dans les sites Web collaboratifs actuels, un effort de saisie important est demandé aux utilisateurs afin d'identifier la communauté à laquelle ils appartiennent (description du profil personnel, du réseau social, etc.). Dans cet article, nous proposons une méthode de découverte de communautés basée sur les actions des utilisateurs. Elle repose sur une analyse en composantes principales des usages (ACP) et a été validée sur une base de données de préférences filmographiques de grande taille (MovieLens).

Context-aware semantic Web service discovery protocol
2009
The Web of today represents a broad space where users research, discover and share information. In this context, the process of Web service discovery plays a significant role. Indeed, such process allows linking the information published by service providers and the requests of users, looking for information. Generally, such process involves text or keyword-based techniques. Still, this kind of discovery fails in retrieving only relevant information. Our approach is to design a more " intelligent " system that allows using a knowledge base during the service discovery process, as it is done in the Semantic Web vision. This thesis presents a framework for semantic Web service discovery using…
