A New Method of Text Categorization Based on Feature Aggregation and LSI

The paper put forward a new method of text categorization based on FA and LSI. The new method establishes vector space model of term weight by the theory of FA and LSI, which decreases the dimension of vector, and enhances the function of the words from the viewpoint of categorization effect, and then the semantic factor is enhanced. Therefore the new method advances largely the speed and the precision of text categorization
