Facing a great deal of materials and data in the process of design and manufacturing of clutch product, Quick and accurate knowledge extraction from the literature resources and web pages is a key to the design of vehicle clutch. The motheds of automatic knowledge acquisition based on literature and XML pages were proposed as well as specific algorithms and processes of knowledge extraction from documents and web pages were constructed.Techniques of knowledge element extraction, agent and ontology were applied to the intelligent type selection system.Practice tells that this intelligent type selection system can better assist intelligent type selection and design of vehicle clutch and knowledge management
