Research on manufacturing resource domain ontology integration based on OWL

At present, cooperation between manufacturing enterprises is becoming important. Many manufacturing enterprises establish their own manufacturing resource domain ontologies. In order to achieve knowledge reuse and sharing among different manufacturing resource domain ontologies, the method of manufacturing resource domain ontology integration was introduced. Three cases-equivalence, parallel, and intersection were proposed. Based on analyzing the characteristics and functions of manufacturing resource domain ontology, a new concept similarity computation algorithm was introduced for the manufacturing resource domain ontology. Both information content-based similarity computation and distance -based similarity computation were considered in this algorithm. At the end, an instance about integration of two part of different manufacturing resource domain ontologies was shown.
