SIOC --- Semantically-Interlinked Online Communities --- provides the Semantic Web with a vocabulary for representing activities and contributions of online communities. However, it focuses on the state of online communities at a given time, while a number of Web application put a strong emphasis on the <i>dynamics</i> of their components and users,(More)
In this article we present a new approach for modeling a user’s experience in using a computer system. In this perspective, we developed the Musette approach. It relies on the building of a use trace conforming to a general use model, describing the objects and relations handled by the user of the computer system. This primitive trace can then be analyzed(More)
Active reading of audiovisual documents is an iterative activity, dedicated to the analysis of the audiovisual source through its enrichment with structured metadata and the definition of appropriate visualisation means for this metadata, producing new multimedia objects called hypervideos. We will describe in this article the general decomposition of(More)
One of the challenges of the Semantic Web is to integrate the huge amount of information already available on the standard Web, usually stored in relational databases. In this paper, we propose a formalization of a logic model of relational databases, and a transformation of that model into OWL, a Semantic Web language. This transformation is implemented in(More)

In this paper, we present a Trace Based framework for managing and transforming traces of observation and use of real life objects. Considering trace based systems as Digital Object Memories (DOMe), we describe how our framework can be used to manage DOMe, using trace models and transformations to raise the abstraction level of traces and infer useful(More)
