In cloud manufacturing system, the distributed stored knowledge is in multiple forms and structure, and its contents are in multiple fields. In this paper, a semantic search engine method based on shared ontology is presented. The application status of ontology in semantic search is studied. In order to enhance the recall rate and precision rate, this search engine computes the semantic matching degree between user requirements and knowledge by semantic similarity computing and logical reasoning.
