摘　　要：在协同产品开发领域,为了实现产品数据语义互操作,提出了一个基于本体的产品数据语义互操作框架。首先,框架采用标准化方法,构建产品数据语义描述语言形式化表达产品模型;然后,组合语义等价和语义相似性度量方法在已有的应用本体和产品数据语义描述语言本体之间建立完善的映射关系;最后,以产品数据语义描述语言本体为中介,实现应用本体间的转换,完成异构计算机辅助设计系统间产品数据语义互操作。原型系统和应用实例证明了该框架的可行性和有效性。To realize semantic interoperability of product data in collaborative product development field, an ontology-based framework for semantic interoperability was proposed. Firstly, a standard-based approach was used to develop a Product Data Semantic Representation Language （PDSRL） formalizing product data. Then, mapping rela tionship was established between an existing application ontology and the PDSRL ontology by using semantic equivalence and semantic similarity assessment. Finally, taking the PDSRL ontology as a mediator, the data exchange was implemented among application ontologies, and semantic interoperability of product data was realized among heterogeneous Computer Aided Design （CAD） systems. A prototype system and an application instance were presented to demonstrate the feasibility and effectiveness of the framework.
