Keyword:  rough setvalue set reductioncut setrough logic;
Abstract: For the discretization reduction of attribute,Andrzej Skowron gave a cut set method.This method is simple and feasible,but in the case of attribute values being compact,the cut set is large,and the reduction efficiency of the data is lower.Rough logic method is proposed for an extraction and reduction of cut set used by Andrzej Skowron,and the corresponding heuristic attribute value reduction algorithm is given,The efficiency is improved obviously.
