A new machine learning method of Support Vector Machine (SVM), is applied in automatic text categorization. Comparing with the result achieved by k-nearest neighbor algorithm, the accuracy achieved by support vector machine is better; The effect of feature selection methods is smaller to SVM than the KNN method. The SVM is a potential and competitive method for automatic text categorization. The feature selection methods also affectes the accuracy of text categorization.
