Firstly, the defects of method based on mutual information in the feature selection are analyzed theoretically,then an improved method is put forward. According to the problems of vector space model, the authors use a class space model to express text and take advantage of  the category information. In this way, the paper realizes an algorithm of text categorization based on category,and the result based on the Chinese text categorization shows that this method has a better precision in the text categorization.

Key wordsText categorization        Feature selection        Class space model        Feature reduction
