摘要
Abstract
In text classification, feature selection is essential to make classification efficient and more accurate. This paper depends on deficiency of x2 statistics and presents an improved x2 statistics method. Experiments based Support Vector Machine show that the improved method can improve the classification accuracy.关键词
