摘　　要：重用已有设计必须理解设计原理 ,从各种文档中提取设计原理信息 ,但其完整性和一致性很难得到保证 .文中提出一种基于本体的设计原理信息提取方法 ,该方法以设计原理的知识模型为基础 ,通过查询驱动的用户界面 ,动态地预测设计人员所关心的问题 ,并给出相应的回答 .在文献综述和案例分析的基础上 ,文中建立了设计原理的本体 ,并以铁路货车转向架设计为例说明了智能信息提取的实现 .初步研究表明 ,与文档管理和关键字搜索相比 ,这种基于本体的设计原理信息提取方法具有完整性和一致性等优点 ,可以作为 KBDSS(Knowledge- Based DesignSupport System)的技术基础之一 .Understanding design rationale is necessary for design reuse. The completeness and coherence of design rationale information got from various documents are difficult to be guaranteed. This article presents an ontology based method for design rationale information retrieval. The method is based on the knowledge level model of design rationale. Through the query driven user interface, the questions from which the designer wants to know about the design are dynamically generated and the answers of the questions are presented. We build the ontology of design rationale based on related empirical studies and our own case analysis. The implementation of the method is illustrated with an example of railway freight car bogie design. Elementary study shows that the method has the advantage of completeness and coherence over conventional information retrieval based on document management and keyword search. It is believed to be one of the well founded techniques of Knowledge Based Design Support System.
