专家系统中知识库组织与维护技术的研究

Research of Knowledge-base Organization and Knowledge-base Maintenance Techniques in Expert System

为了提高知识的利用效率 ,提出了一种“顺序存储 ,动态组织”的知识库组织策略。在知识库维护方面 ,提出了基于规则知识库的环路检测 ,不可达选择子、闭塞选择子检测 ,等价、从属、冲突规则集检测等三个知识库维护算法 。

In order to improve using efficiency of knowledge, a knowledge organization strategy described as orderly storage and dynamic organization is presented. As to knowledge base maintenance, three algorithms including rule circle detection algorithm, inaccessible selectors and dead selectors detection algorithm, and equivalence rule set, appurtenant rule set and conflict rule set detection algorithm are put forward, and some examples are given to each algorithm respectively.
