摘    要:提出了一种基于粗糙集的知识理论模型,运用这一模型对决策表进行属性约简,去除其中不必要的属性,揭示出条件属性中的冗余性,最后得出了属性约简的结果以及决策规则。给出了一个简单的例子来说明如何建立和应用这种知识理论模型。

关 键 词:粗糙集理论  知识发现  属性约简  决策规则  决策表  信息系统  知识规则

Abstract:A theory model based on rough sets is presented.By exercising this model,we have put up property reduction to the decision table and eradicated the unnecessary ones,exposed the re-dundancy in conditional properties,finally got the property reduction result and decision-making rule.A sample is given to explain how to build up and use this kind of theory model.
Keywords:rough sets  knowledge discovery  reduction  decision-making rule
