Abstract
RDF(S) is the emerging standard for knowledge representation on the Web. In the CoMMA European IST project dedicated to ontology guided Information Retrieval in a corporate memory, the semantic annotations describing the Intranet documents are represented in RDF(S). In this context, the RDF(S) expressivity appears to be too much limited for efficient IR. In this paper, we present DRDF(S), an extension of RDF(S) to express class and property definitions and axioms as ontological knowledge, and more generally contextual knowledge on the Semantic Web. Our approach is underlain by the existing mapping between RDF(S) and CGs: DRDFS -the extension of RDF(S) we propose- is based on features of the Conceptual Graphs model. We argue that CGs meet the needs of the Semantic Web and we hope that DRDF(S) will contribute to the ongoing work of the W3C committee for improving RDF(S).
