This paper deals with the exploitation of the lexical and conceptual knowledge coded in the SIMPLE-DK lexicon in the methodology for content-based querying developed by the OntoQuery project. SIMPLE-DK has proven a rich and flexible lexical resource, which the project has taken advantage of in several ways. Firstly, the paper explains how the ontology provided by SIMPLE is used by the current project prototype to derive conceptual descriptors on which to base the matching of documents to user queries. Furthermore, it discusses how selectional restrictions and qualia roles, both coded in SIMPLE, can be used to construct an ontological grammar to build more complex descriptors.
