abstract:the lacking of semantic expression is a bottleneck of currently web service based internetbased manufacturing solution. it is not easy to dynamic discover appropriate services from different service providers. this paper put forward a method of ontologybased knowledge modeling. it combined web service with network manufacturing service and constructed the servicedriven manufacturing ontology model by applying the method. the evaluation method of approximate service matchmaking is also developed， and the case is given to demonstrate mentioned above. the study solves three problems during the course of manufacturing service， which were communication between different roles，data exchange and reuse of knowledge resource. the share and the configuration optimization of distributed manufacturing resources were realized in the network manufacturing environment. it lays the foundation for the construction of the semantic webbased collaborative manufacturing service platform.......
