Research on Semantic Conjunctive Query over Database
Shengqun Tang · Jisuanji gongcheng · 2010
To solve weak semantics problem of integrating heterogeneous databases by semantic technology,which is caused by the scale of records,an algorithm is proposed. It gives consideration to efficiency and reasoning ability. Ontology and queries are expressed as graphics. Sub-graph is matched with semantics. The result is translated into database query language. This algorithm supports more rich semantics than the algorithm that rewrites semantic query into SQL does.
