Zusammenfassung:	This paper describes an information extraction system, Vulcain, dedicated to message filtering for a specific domain. The paper focuses on a method for identifying domain-specific terms and concepts, using syntactic information and an existing domain ontology. We focused on a method for identifying terms by partial syntactic analysis, based on TAG grammars. The domain ontology is represented in description logics, and DL inference mechanisms are used to validate the candidate concepts.
