基于本体和设计情景的产品设计领域知识问答系统研究

Research on the Knowledge QA System in the Field of Product Design Based on Ontology and Design Context

文章提出了一种基于本体和设计情景的产品设计领域知识问答系统解决方案,利用本体表示产品设计知识库,提出了基于问句语义特征匹配的问题分类算法以及本体查询转换技术,并充分考虑问句中带有设计情景的复杂问题,提出情景相似度和问句相似度综合加权的设计情景问题相似度算法,最后设计实现了身管设计知识问答系统,并对实验结果进行分析验证方案的可行性。

This paper proposes a knowledge QA system in the field of product design based on ontology and design context,and uses ontology to present product design knowledge database. The paper puts forward question classification algorithm based on semantic feature matching of questions and ontology query conversion technology. Considering the complex problem with design context in questions,the paper proposes design context similarity algorithm that combined context similarity and questions similarity with weight. Finally,the paper designs and achieves a knowledge QA system based on barrel,as well as analyzes and verifies the feasibility of the experimental results.
