摘要
首先给出知识表达系统及决策表的距离图的概念 ;随后 ,借助距离图的性质 ,得到一种知识表达系统相容性判定与求核的方法 .特别地 ,这种方法可用于决策表相容性判定及条件属性核的求解 .最后 ,建立了一个利用约简决策表的距离图求决策规则的核值及最小决策算法的算法框架 .
First, the distance graphs of knowledge representation system and decision table are defined in this paper. Second, by using of their properties, a method of consistency judging and an approach to get the core of the knowledge representation system are obtained. particularly, these methods can be used to judge the consistency of the decision table and work out the core of decision algorithm. At last, applying the distance graph of the reduced decision table, we propose a way to get the core of each decision rule.
