Towards a Semantic Web Mediator: SPARQL Query Reformulation

We propose a federated environment based on a Mediator Architecture in the Semantic Web. The Mediator supports mappings between the OWL Ontology of the Mediator and the other ontologies in the federated sites. SPARQL queries submitted to the Mediator are decomposed and reformulated to SPARQL queries to the federated sites. The evaluated results return to the Mediator. In this presentation we are going to describe the mapping capabilities and the reformulation process that are used by the Mediator system we are implementing.
