Research on ontology-based integration of product knowledge for collaborative manufacturing

One of the most important research subjects germane to knowledge management in collaborative manufacturing is the integration of heterogeneous product knowledge distributed among different collaborative enterprises. To deal with the problem of optimization of knowledge integration in collaborative manufacturing, an ontology-based framework of knowledge integration is presented to transform the problem of knowledge integration into a problem of ontology integration. First of all, a collaborative business process for collaborative enterprises is described, and then an ontology-based framework of knowledge integration is established. Under the condition of analyzing the structure of knowledge ontology, an ontology schema of knowledge concept is discussed. Aiming at the ontology schema, a method of ontology integration based on ontology similarity is improved. The method is composed of ontology mapping and ontology merging, which is based on calculated result of ontology similarity between local ontology and global ontology. Finally, the implementation of the framework of knowledge integration is described, and the application results meet the requirement of the knowledge integration to ensure that validity of the ontology integration method was proved.
