Knowledge-based query expansion over a medical terminology oriented ontology on the web

Abstract

This paper deals with the problem of information retrieval on the Web and present the CISMeF project (acronym of Catalogue and Index of French-speaking Medical Sites). Information retrieval in the CISMeF catalogue is done with a terminology that is similar to ontology of medical domain and a set of metadata. This allows us to place the project at an overlap between the present Web, which is informal, and the forthcoming Semantic Web. We also describe an ongoing work, which consists of applying three knowledge-based methods in order to enhance information retrieval. © Springer-Verlag Berlin Heidelberg 2003.
