Querying the Semantic Web with the CORESE search engine (Submission to PAIS)

Olivier Corby, Rose Dieng-Kuntz, Catherine Faron-Zucker

The semantic Web relies on ontologies for representing domains through their main concepts and the relations between them. Such a domain knowledge is the keystone to represent the semantic contents of web resources and services in metadata associated to them. These metadata then enable a search for information based on the meaning of web resources rather than their syntactic forms. In this paper, we present an ontology-based approach for web querying, using semantic metadata. We propose a query language based on ontologies and emphazize its ability to express approximate queries, which is of prime importance for an efficient information retrieval on the web. We present the Corese search engine we hable developed to handle RDF(S) metadata and we illustrate its interest through several real-world applications.

Keywords: ontologies, semantic Web, search engine, RDF, conceptual graphs, query language
