大学生心理咨询专家系统中推理知识的研究

Research on Reasoning Knowledge in Psychological Consultation Expert System for College Students

推理机是大学生心理咨询专家系统的指挥中心,控制着整个系统的运行;心理咨询知识具有一定的模糊性,为了便于系统推理,在每个事实的后面添加一个数值,用来描述事实的真实程度;心理咨询专家系统的知识表示采用基于加权模糊的产生式表示形式,推理机采用基于加权的模糊推理;分析了推理知识的不确性、研究了推理算法的设计,阐述了系统中采用的推理算法。

Analytic reasoning machine is the guiding center in psychological consultation expert system for college students and controls the operation of the whole system. Psychological consultation knowledge has certain fuzzy feature, in order to help systematic reasoning, a number is added to every fact to describe the authenticity of the fact. The knowledge representation in the psychological consultation expert system is indicated by reasoning process based on weighted fuzzy factors, and the reasoning machine is based on weighted fuzzy reasoning. This paper analyzes the uncertainty of reasoning knowledge, studies the design of reasoning algorithm, and elaborates the reasoning algorithm in this system.
