Yaping Wang, Jianghua Ge, YongChao Tao, Junpeng Shao · 2009
Semantic heterogeneity is the key and difficult question of interoperability of heterogeneous data. For the semantic heterogeneity of heterogeneous data interoperability in the network manufacturing enterprises, ontology building and mapping method, the paper put forward building framework of heterogeneous data, which extracts relational schema from relational database, based on the analysis of theoretical research related to ontology, a multi-strategy method of ontology map is proposed and the similarity calculation is carried out on ontology mapping. Finally, reducer is used to build experimental ontology, and verified that the method possesses high recall and accuracy, which provides effective ways and means for resource sharing and reuse of knowledge in the manufacturing enterprises.
