Mediating RDF/S Queries to Relational and XML Sources

Abstract: Semantic Web (SW) technology aims to facilitate the integration of legacy data sources spread worldwide. Despite the plethora of SW languages (e.g., RDF/S, OWL) recently proposed for supporting large-scale information interoperation, the vast majority of legacy sources still rely on relational databases (RDB) published on the Web or corporate intranets as virtual XML. In this article, we advocate a first-order logic framework for mediating high-level queries to relational and/or XML sources using community ont… Show more

“…In the present work, we assume that the mapping between the schemas of the Web Services and the schema of the knowledge base is given. The (semi) automatic creation of schema mappings has been addressed in a large corpus of works, e.g., [16,3,24]. Furthermore, we are not concerned with entity disambiguation and data fusion in this paper.…”

“…En revanche, la traduction d'une requête du schéma global en requêtes sur le schéma des sources demande un mécanisme de réécriture de requêtes complexe. Il existe des systèmes, tels SWIM (Koffina et al, 2006) adoptant une approche GLAV permettant de mettre en correspondance des éléments de l'ontologie avec des éléments de schémas de sources. Ces systèmes relèvent à la fois des approches GAV et LAV et tirent ainsi profit de leurs avantages respectifs.…”
