Deep Semantic Integration for Information System

Abstract

When applied semantic integration technology to databases, common method is to rewrite semantic query into SQL statements, while only RDFs vocabularies are supported at most. Semantics having been realized is weak. A more perfect algorithm inherited from the idea of rewriting semantic query is proposed, a sub set of OWL is supported, and semantics having been supported is more deep than ever. Ontology and query all are transformed into graphs, semantic match is done. Applying breadth-first search on match result, SQL statements will be generated. A case is designed to exemplify it, which shows that some OWL constructors have been supported.
