Programma di ricerca (cofinanziato dal MIUR, esercizio 2004) Ricerca Intelligente su Web basata su Ontologie di Dominio Web Intelligent Search based on DOMain ontologies Critical analysis of query languages and ontology-based query rewriting techniques

As the final outcome of our work in the context of the Wisdom project, a prototype for query formulation has been developed in order to prove the validity of the M-FIRE framework [3, 5, 4], and the feasibility of our approach to knowledge representation and exploration. The prototype includes a client module (written in C#) and a server module (written in Java) which communicate through a state-based TCP connection. Many clients can connect to a single M-FIRE server and deliver requests to it. In a typical scenario, clients would ask for a representation of some part of the available knowledge, and the server would reply by returing semantically annotated XHTML pages (the M-FIRE framework can actually support other representation formats than XHTML); after rendering is completed, actions made by the user on such documents will trigger new requests, which are eventually translated into SPARQL queries; the results of the generated queries are processed by the M-FIRE server and translated into a new XHTML document, which is then sent back to the client for rendering.
