Semantic Interoperability for Mobile, collaBorative and ADaptive applications

SIMBAD is a structuring research project of the Institut Telecom. We are part of the Computer Science Department of Técom SudParis one establishment for higher education and research in the field of Information and Communication Technology of the Institut Técom

We are also part of the CNRS research laboratory SAMOVAR.

The SIMBAD project has been started in january 2004. SIMBAD mainly addresses the complex manipulations of resources and services in a dynamic and large scale distributed system. These manipulations include searching, classifying, indexing, reusing and composing. We are considering dynamic systems where nodes may arrive or quit the system at any time. Our approach does not suppose that all nodes are strongly coupled (e.g we do not suppose the existence of a common global schema). For the moment we are working separatly for resources (data described by metadata) and services (programs described by interfaces). Two main applications are addressed; e-learning environment and sharing of pedagogical resources (so-called learning objects); virtual entreprises (dynamic interconnection of information systems described by services and workflows).

To fulfill these objectives, our general idea is to add semantic information to describe resources and services. These semantic informations are then used by the different manipulation processes. Ontologies are used to define a common referential to define semantic informations. The final goal of this project is to work on unifying our work on resources and services in a more generic approach. SIMBAD is structured into three main components: metadata for learning objects and adaptation, virtual entreprises, semantic P2P systems.
