Abstract: Under the network environment,in order to achieve the integration management of the distributed parts resource and,an ontology-based integration architecture for parts resource library is proposed to satisfy enterprises' requirements for parts information sharing and reuse in the knowledge level.Based on this,an ontology-driven method for distributed parts resource library construction is studied,and the automatic integration algorithm and its example of parts resource library are also presented,based on the shared ontology.In addition to discover parts resource as much as possible,ontology-based parts resource semantic retrieval method is adopted.At last,a prototype system is developed to verify the feasibility of the methods discussed above,and indicate that it is good way to provide a semantic-based and integrated parts resource retrieval and application entrance for designer to further improve the utilization and reuse degree of the existing parts resource.

Key words: ontology, distributed parts resource library, auto-integration, semantic retrieval
