摘要: 提出面向问题分析与决策专家系统的知识库构建方法,并用于公路工程质量问题智能分析与诊断专家系统开发。以问题为核心,根据关键的基本对象、问题对象、问题现象对象、原理知识对象和过程知识对象(MP4对象)对知识进行筛选,实现知识领域化,对其进行抽象和分类得到层次化表示的问题对象树,以问题对象树为依据构建知识字典和知识关系。结果证明该方法可以较快地建立知识库。

关键词: 专家系统, 面向问题分析与决策, 知识库构建, 问题对象树

Abstract: A knowledge base construction method for Problem Oriented Analysis and Decision Expert System(POADES) is proposed and used in the development of highway projects quality intelligent analysis and diagnosis expert system. It uses problem as the core. It screens knowledge and realizes knowledge’s field-dividing in accordance with the key Meta-object, Problem-object, Phenomenon-object, Principle object and Process object (MP4 objects), and abstracts and classifies knowledge to get hierarchical tree of problem object. It constructs knowledge dictionary and knowledge relation according to the tree of problem object. It proves that the method can construct the knowledge base quickly.

Key words: expert system, problem oriented analysis and decision, construction of knowledge base, tree of problem object
