基于本体的零件库信息模型

Information Model of Parts Library Based on Ontology

零件库是企业产品开发设计过程中积累的大量信息和知识的集合,研究零件库信息的表达对于企业资源利用具有重要意义。在分析零件库信息的内容和组织的基础上,根据GB/T 17645.42标准对零件库进行分类,构建基于本体的零件库信息模型。通过基于本体的零件库信息的语义表达,降低零件库信息冗余度,优化零件库信息的表达,同时本体的语义信息给零件库信息的检索和重用提供了基础模型,最后给出了以OWL语言表达的零件本体和实例。

Parts library is a collection of information and knowledge accumulated in the course of design development of enterprise products.The study of information representation of parts library plays an important part in utilizing enterprises′ resources.Based on analyzing the content and organization of parts library,parts library is classified by the standard GB/T 17645.42,parts library information model is set up based on ontology.Semantic expression of parts library information and ontology reduce the redundancy of parts library information,and optimize the description of parts library information.The semantic information of ontology provides a basic model for retrieving and reusing parts library information.Parts nut ontology and a case are presented by OWL.
