基于本体的分布式零件资源库集成及语义检索研究

Research on ontology-based distributed parts resource library integration and semantic retrieval

为实现网络环境下分布零件资源的集成管理,并满足企业在知识层面上对零/部件信息共享和重用需求,提出基于本体的零件资源库集成架构;基于此研究本体驱动的分布式零件资源库构建方法,并给出基于共享本体的零件资源库自动集成算法及实例;为尽可能全面地发现零件资源,采用基于本体的零件资源语义检索方法;最后开发原型系统验证上述方法的可行性,通过给设计用户提供一个基于语义的零件资源检索和应用集成入口,可进一步提高现有零件资源的利用率和重用程度。

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.
