基于PCP理论,提出一种新的知识获取方法和一种新型的知识表达方式——知识矩阵的概念,定义一种模糊关系合成的修改算法公式以及推出一种关系描述图的新算法GRP,以吸取和精炼领域专家的有关知识。这种算法和概念均成功地应用于KAS1知识获取系统,并生成了计算机算法语言咨询的知识矩阵,为知识获取提供了一种新的途径。 Based on the theory of PCP, this paper proposes a new knowledge acquisition method and a new type of knowledge expression - the concept of knowledge matrix, defines a modified algorithm formula for fuzzy relation synthesis, and introduces a new GRP algorithm for relation description Absorption and refining experts in the field of knowledge. These algorithms and concepts are successfully applied to KAS1 knowledge acquisition system and generate a knowledge matrix of computer algorithm language consultation, which provides a new way for knowledge acquisition.
