Concerning the difficulties of experience knowledge acquisition during knowledge integration process of die and mold enterprises,a knowledge acquisition framework based on experience feedback model was proposed.First,the knowledge acquisition method based on mold product lifecycle was studied and the Ontology-based knowledge extraction and representation were realized,conceptual graph was adopted to construct visual modeling and Web Ontology Language(OWL)was used to describe and store knowledge in a uniform way.Then,the structure and the runtime principle were stated.Finally,the knowledge acquisition services of mold enterprise integration platform based on service-oriented architecture were implemented.As the proposed framework satisfies the experience characteristics and adopts streamlining knowledge acquisition process and visualization representation methods,the difficulties and the costs are reduced.
