自从六十年代末期,人们将人工智能的一些基本原理用于建立医学专家系统以来,已经涌现出一大批具有实用价值的医学专家系统。本文提出了一个以大量临床资料为基础的,以多年临床经验为前提的可摘局部义齿计算机辅助设计专家系统,并用“C”语言获取和表示启发式知识,从而可以较好地解决可摘局部义齿专家系统中自动知识的获取,知识表示和学习等困难问题。 Since the late 1960s, when people applied some basic principles of artificial intelligence to the establishment of a medical expert system, a large number of practical medical expert systems have emerged. This paper presents a computer aided design expert system of removable partial dentures based on a large amount of clinical data and based on years of clinical experience. The “C” language is used to acquire and express heuristic knowledge so as to solve the problems of the removable partial Denture expert system automatic knowledge acquisition, knowledge representation and learning and other difficult issues.
