An Ontological Representation of Documents and Queries for Information Retrieval Systems

This paper presents a vector space model approach, for representing documents and queries, using concepts instead of terms and WordNet as a light ontology. This way, information overlap is reduced with respect to the classic semantic expansion techniques. Experiments undertaken on MuchMore benchmark showed the effectiveness of the approach.
