Unifying Data and Domain Knowledge Using Virtual Views Kalyana Krishnan Overview
... properties are drawn into a transitive tree and implication rules into an implication graph. When the queries are issued against the virtual view, a query rewriter rewrites the queries to retrieve appropriate information from the relational tables as well as the ontology. ...
