Abstract: The attribute reduction of incomplete and inconsistent data is a major content of data mining.Combining information gain and inconsistent degree of data,this paper proposed an attribute reduction algorithm for incomplete and inconsistent data.First,the information gain is introduced,and the concept and algorithm formula of inconsistent degree are defined.Besides,the method of data filling based on information gain and inconsistent degree is given.Then,based on this data filling method,the attribute reduction algorithm is provided with the information gain under the condition of taking the maximum inconsistent degree as the weight and inconsistent degree as heuristic information.Finally,the experimental results demonstrate the effectiveness of the proposed algorithm.

Key words: Attribute reduction, Filling, Incomplete, Inconsistent, Information gain
