Local Ontology Based Semantic Query Decomposition Algorithm

Aiming at algorithm limitations and lower recall rate of query decomposition, a query decomposition algorithm based on FWR expressions of ontology XQuery is proposed. In this algorithm, after writed query language the global by XQuery, in the three stages of the FWR expression global ontology-based query is decomposed into sub-queries for the local body. The Algorithm reduces the complexity of the query decomposition, ensures the semantic integrity, and then increases the recall rate. An illustrative example as well as the experimental results demonstrates the effectiveness of the proposed method.
