Abstract  

This paper applies the improved information gain method to the text clustering. Retrieving 250 from the corpus, according to Vector Space Model and the information gain feature selection method,construct the text feature vector;use C-means to automatic clustering, the precision、recall and F-measure are 0.82、0.88、0.83.
Key words： Information gain      Feature selection      Clustering
