用于研究专家系统的另一神模型──判别树及其寄生树

Discrimination Tree and Its Parasitic Tree: A New Model for Studying Expert Systems

本文提出的判别树是一种既系统又直观地描述判别思路的模型，寄生树是一种用来判定判别树中结点的子特征的判别树。在专家系统的研究中，应用本模型有三个优点：①可有条理地描述、整理复杂的分类判别知识；②易于转换出相应的产生式规则或框架形式的知识库；③能清晰直观地指导设计高效的判别推理机。

This paper presents a new model, 'discrimination tree' and its 'parasitic tree', to more efficiently study expert systems. The discrimination tree is a tree to systematically describe discriminating knowledge. The parasitic tree is a discrimination tree used to determine the sub-features of the nodes of another discrimination tree. The trees can be used to systematically describe complicated discriminating knowledge and to clearly design high-performance classification inference engines. In addition. They can be easily translated into a knowledge base in the form of production rules or frames.
