基于本体的Web零件库数据描述规范

Research on Ontology Based on Data Description Norm of Web Parts Library

提出了一种基于本体的Web零件库数据描述规范,结合零件族和事物特性表建立了Web零件库的框架,解决了零件库数据共享和重用的问题。通过扩充零件的CAD模板、事物特性表和本体库实现了零件库动态扩充。建立了基于零件本体的多层次检索模型,通过垂直匹配与水平匹配两次匹配来提高查询准确率。建立了一个Web零件库原型系统,验证了数据描述规范方法的可行性。

An ontology based data description norm of web parts library was proposed. With the help of parts family and article characteristics table, the framework was built to solve the problem of parts data sharing and reusing. The generic and simple parts family was used to build the hierarchy and the article characteristics table was used to store the information of parts instances. Through the expansion of ontology library, CAD template and article characteristics table of parts, the dynamic expansion of web parts library was realized. A multilevel query model was brought out, and vertical and horizontal matching was used to deal with the problem of query precision. A prototype of ontology based on web parts library was constructed to verify the feasibility of above methods.
