| Abstract(in English) | Feature selection is a well-known approach for improving the prediction performance of document classifcation, where crucial words are selected and used in vectorization of the documents. This paper proposes an improvement of feature selection of [Sakai & Hirokawa 2012] by considering the occurences of words in ths support vectors. We conducted the evaluation of the proposed method on reuter dataset and confirmed that the proposed method yields allmost the same performance with a small number of feature words. |
