The problem of subject classification on network public opinion in public safety was addressed in this paper. Subject dassificafion need to solve five issues. Firstly, a classification system was established on network public opinion in public safety. Secondly, methods of document feature extraction and selection were introduced. Thirdly, the vector space model was analyzed. Then, Two kinds of classification algorithms, KNN and SVM were implemented. Finally, the result of experiments were proposed.
