In this paper, we propose an emotion separated method(SeTF・IDF) to assign the emotion labels of sentences with different values, which has a better visual effect compared with the values represented by TF・IDF in the visualization of a multi-label Chinese emotional corpus Ren_CECps. Inspired by the enormous improvement of the visualization map propelled by the changed distances among the sentences, we being the first group utilizes the Word Mover's Distance(WMD) algorithm as a way of feature representation in Chinese text emotion classification. Our experiments show that both in 80% for training, 20% for testing and 50% for training, 50% for testing experiments of Ren_CECps, WMD features get the best f1 scores and have a greater increase compared with the same dimension feature vectors obtained by dimension reduction TF・IDF method. Compared experiments in English corpus also show the efficiency of WMD features in the cross-language field.
