Schema-Based Query Rewriting in SPARQL

SPARQL query in the semantic web has drawn consideration attention from the OWL and RDF communities. In this paper, we present SPARQL-S, a new system for SPARQL entailment regime focused on fast and efficient querying with meaningful ontology schema and large volumes of RDF data. The basic idea of SPARQL-S is different from the previous SPARQL entailment implements which are mostly archived by deriving additional facts. SPARQL-S focuses on how to rewrite the BGP in SPARQL to include more entailment BGP information absorbed from ontology schema by concept entailment and then query the rewritten SPARQL in a distribution graph computation framework such as GraphX.
