模仿思维的医学专家系统

A Medical Expert System That Simulates Thought

医学信息有其独特的性质，不适合用关系数据库来处理；用Ｐｒｏｌｏｇ语言来处理医学信息又需要大量的规则。本文是模仿后一种解释而建立的专家系统。该专家系统中的一个数据记录只相当于当前的文件系统的一个数据记录中的一个数据项。这种数据结构很适用于医学知识的存放，它结构简单，功能却非常强大。该专家系统在诊断疾病时主要以查寻为主，只有少量的判断，几乎不存在逻辑推理，也不需要规则，比用Ｐｒｏｌｏｇ语言开发出来的专家系统有明显的优点。

Dbase can' t process medicine information.Prolog needs a lot of rules and is not sasy to operate An expert system that simulates thought is presented in this paper The data structure is suited to store medicineknowledge. To diagnose a disease. the expert system uses mainly searching to judge. has no logical deduction,needs no rules and is better than expert system which uses Prolog.
