| Abstract: | In this paper, we study the problem of rules reduction for real value information systems by using of rough set theory. Existing methods for rules reduction are applicable to unreal value knowledge systems, not adequate to highly effective large scale data processing especially for real value knowledge systems. Based on the theory of rough set, a method for rules reduction to real value knowledge systems is proposed in this paper. Experimental results show the method is feasible and effective both for real value knowledge systems and unreal value knowledge systems. The method gives a way to effectively deal with knowledge systems for rules reduction. |
