Creation and use of lexicons and ontologies for natural language interface to databases

In this paper we present an original approach to natural language query interpretation which has been implemented within the FuLL (Fuzzy Logic and Language) Italian project of BC S.r.l. In particular, we discuss here the creation of linguistic and ontological resources, together with the exploitation of existing ones, for natural language-driven database access and retrieval. Both the database and the queries we experiment with are Italian, but the methodology we broach naturally extends to other languages.
