模糊PROLOG语言为专家系统的研究拓宽了道路,本文扼要介绍了新型模糊PROLOG语言一f-PROLOG,旨在说明它的基本语法,以及它和传统PROLOG语言的异同。进而,着重讨论了专家系统中的知识表达和非精确推理,指出传统的知识表达方式和推理方法因缺乏必要的模糊逻辑方法论背景而把大量的模糊信息和经验知识排斥在外,并通过实例说明f-PROLOG不仅是一种良好的知识表达工具,而且很适合用做专家系统的推理机。
Fuzzy PROLOG language for the expert system to open the way for the study, this article briefly introduces the new fuzzy PROLOG language f-PROLOG, designed to illustrate its basic syntax, as well as its similarities and differences with the traditional PROLOG language. Furthermore, the knowledge system and inaccurate reasoning in the expert system are emphatically discussed. It is pointed out that the traditional way of knowledge expression and reasoning excludes a large amount of fuzzy information and experience because of the lack of necessary fuzzy logic methodology background. -PROLOG is not only a good tool for knowledge representation, but also suitable for use as an expert system inference engine.
