    The increasingly popular web 2.0 sites provide the largest social network ever analyzed - users are now considered as plain web resources. Some researchers apply classical methods of social network analysis to such networks; others provide models to leverage the semantics of their representation. We present a state of the art of these two approaches and propose an architecture to merge and exploit the best features of each

    Problèmes liés au filtrage de Volterra appliqué à l'égalisation adaptative non linéaire

    Dans cet article, nous montrons que l'approche qui consiste à utiliser un filtre de Volterra pour inverser un canal modélisé par un filtre de Volterra soulève des difficultés. Les limitations que nous soulignons concernent non seulement la structure de filtre de Volterra, mais aussi son optimisation suivant.. le critère de minimisation de l'erreur quadratique entre sa sortie et le symbole désiré. Nous donnons ainsi des conditions sur la constellation des entrées du canal pour qu'un égaliseur optimal unique existe

    International audiencethis is a collective position paper presenting the vision, motivations and approaches of the ISICIL project. This project proposes to study and to experiment with the usage of new tools to assist tasks of corporate intelligence and technical watch. These tools rely on web 2.0 advanced interfaces (blog, wiki, social bookmarking) for interactions and on semantic web technologies for interoperability and information processing
