Abstract
Due to the numerous health documents available on the
Web, information retrieval remains problematic with
existing tools. This paper is positioned within
the context of the CISMeF project (acronym of
Catalogue and Index of French-speaking Medical Sites)
and of a future Semantic Web. In CISMeF the resources
are described using a set of metadata based on a
structured terminology which “encapsulates” the MeSH
thesaurus in its French version. Now, the objective is to
migrate the CISMeF terminology, and thus the MeSH
thesaurus, to a formal ontology, so as to get a more
powerful search tool. The paper presents the very first
stage and results of this ongoing project, aiming at
migrating the MeSH to OWL. It reports on the first steps,
which have presently been done, concerning the
automatic transformation of the terminology into OWLDL.
First, the CISMeF terminology has been
“formalized” in OWL. Then, the resulting OWL
“ontology” has been imported under the Protégé editor
which makes possible to check its consistency and its
classification in using Racer. Finally, the paper
concludes on the current results and encountered
difficulties, and gives future work perspectives.

Abstract. This paper describes a method for converting existing thesauri
and related resources from their native format to RDF(S) and
OWL. The method identifies four steps in the conversion process. In
each step, decisions have to be taken with respect to the syntax or semantics
of the resulting representation. Each step is supported through
a number of guidelines. The method is illustrated through conversions of
two large thesauri: MeSH and WordNet.
