科学效应知识库的本体构建技术研究
首发时间:2009-01-06
摘要:为了使科学效应知识更好的支持创新性概念设计,分析了科学效应知识支持原理设计的过程,提出了基于本体的科学效应知识库系统模型。构建了科学效应知识本体,利用本体中的对象属性,建立了功能、科学效应、特征流属性和设计实例间的联系。依据系统模型开发了科学效应知识库原型系统,系统支持对本体的推理查询,提供了相关知识表格和用户添加科学效应知识等功能,提高了知识搜索效率及查全率,方便了知识更新和维护。

Research on the Ontology Construction Technology of Scientific Effect Knowledge Base System
Abstract:In order to make scientific effect knowledge support the creative conceptual design more effectively, the process that scientific effect knowledge supports principle design was analyzed, and a model of ontology-based scientific effect knowledge base system was proposed. A scientific effect knowledge ontology was constructed, and using object properties in the ontology, the associations was built among functions, flows, scientific effects, characteristic flow properties and designing instances. A software prototype of scientific effect knowledge base system was developed according to the proposed model, and its function includes: ontology reasoning and query, related knowledge tables and consumers adding scientific effect knowledge, etc. Those functions can improve the knowledge searching efficiency and recall ratio, and make knowledge renewal and maintenance easy. A retrieval instance was presented to demonstrate the feasibility and effectiveness of the model.
Keywords: creative design conceptual design principle design scientific effect knowledge ontology
