摘要
本支阐述了现有专家系统的严重缺陷,指出了基于模糊逻辑的模糊专家系统的重要性。基于测试-评分语义学,重点探讨了模糊命题的规范化方法和模糊知识库的组织,研究了模糊专家系统的推理机制:对未限定化命题的模糊逻辑推理;对量化命题的交/积三段论推理,推论连接三段论推理以及命题链的推理。
In this paper, some serious shortcomings of existing expert systems are described The importance of fuzzy expert systems is pointed out. Based on test-score semantics, the canonical method for fuzzy propositions and the organization of fuzzy knowledge base are discussed, and the inference mechanisms of fuzzy expert systems, i.e the fuzzy logic inference for unqualified propositions, the intersection/product syllogism, the consequent conjunction syllogism and the inference of propositional chain for quantified propositions, are investigated.
