Thesaurus Mapping for Promoting Semantic Interoperability of European Public Services

Interoperability of eGovernment information systems is essential to provide advanced services to citizens. This work proposes a framework for implementing interoperability among thesauri for promoting cross-collection and cross-language information retrieval, as well as a specific approach within such framework on a case study aimed at mapping five thesauri of interest for the European Union institutions (EUROVOC, ECLAS, GEMET, UNESCO Thesaurs and ETT) having only schema information available. In particular the standards as well as the approach for the interoperability case study implementation are presented; finally the interoperability assessment criteria and experimental results for the case study are shown.
