摘　　要：把决策属性看作是一个模糊粗糙逻辑,利用矩阵法求出决策属性对于条件属性的相对正域,给出了基于模糊粗糙逻辑的属性约简的方法,最后根据约简提取规则并计算其精度.Taking decision attribute as a fuzzy rough logic,the relative positive domain for the condition attributes of decision attribute was found by using matrix method,with the attribute reduction method given,based on fuzzy rough logic.Finally,rules extraction were done and its accuracy was also calculated according to the reduction.

关 键 词：模糊粗糙逻辑 属性约简 规则提取
