Abstract
The similarity computation for domain ontology is a critical problem. On the basis of analysis characteristics and functions of manufacturing resource domain ontology, a similarity computation algorithm for the manufacturing resource domain ontology is introduced. It depends on the process capability of manufacturing resource and is quite easier to understand. Then, two applications of this similarity computation algorithm are described, which are manufacturing resource domain ontology integration and virtual manufacturing cell (VMC) search. Both of them are quite helpful for the manufacturing scheduling system.
