The Application Of Fuzzy Reasoning In Pragmatic Environment

Natural language is the main tool of human beings’ communication, and vagueness isone of the basic characteristics. In all aspects, such as phonetics, grammar, semantics,and language used, it attracts people’s attention. Until Zadeh put forward the theory offuzzy set in1960s, people could describe vagueness in scientific ways and develop thebroad field of linguistics of vagueness. In the west countries, especially Englishcountries, vague language is the main direction of linguistic study. Zadeh thinks thatthere are not very clear classification in human being’s mind and in language, and thetransition from the members to the non-members of the classification is gradual, notabrupt. That is fuzzy set. Accurate language is needed in some fields, such as law,economics and artificial intelligence, people will face great difficulties because ofvagueness. In the field of law, binary judges will often be necessary, when facts and actsare determined the nature. The judge is either this or that, and the intrinsic vagueness offacts and acts will be ignored. According to this kind of judge, these facts and acts willbe misunderstood.Fuzzy reasoning that is one kind of tool to describe something is based on fuzzy settheory. According to general set theory as the fundamental describing tool mathematicallogic is expanded so as to establish the fuzzy inference theory that is one kind ofuncertainty reasoning. It has the great significance in the development of artificialintelligence technology.Expert system development tool kits FuzzyCLIPS will be used to quantify themeanings of words in the essay.Creative points of the easy will be represented in two aspects: on one hand, accordingto semantics of vagueness, Expert system development tool kits FuzzyCLIPS will beused to describe the quantification of meanings of words. On the other hand, Expert system development tool kits FuzzyCLIPS will wipe off the vagueness of meanings ofwords in some extents and develop fuzzy reasoning. That will be helpful in the field oflaw and other fields, especially in the judicial practice. It will have a bright future.
