Abstract
This paper presents 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 present a method for identifying terms by partial syntactic analysis, based on TAG grammars. The domain ontology is represented in description logics, using its inference mechanisms to validate the candidate concepts.
