A Framework for Semantic Mapping between Thesauri

Thesaurus interoperability is an important property which guarantees quality in indexing and retrieval of heterogeneous data sources in a distributed environment. It contributes to guarantee semantic interoperability of public services and information quality which are essential features of eGov-ernment implementation policies. This paper presents a methodological framework for semantic mapping between thesauri as well as a specific approach within such framework on a case study aimed at mapping five thesauri of interest for European Union institutions having only schema information available.
