Nowadays, it has been closely studied in the research field of natural language processing ( NLP) due to its w ide real applications. As a result, many supervised machine learning classification approaches have been applied to this task. In this paper, w e research on four classification approaches and propose a new combination method based on stacking to combine these four approaches. Experimental results show t hat our combination method achieves better performances than the best single one. T herefore, this combinat ion method can avoid select ing a suitable classification approach according to different domains.
