| Abstract(in English) | The Text Classification problem has been investigated by vanous techniques, such as a vector space model, a support vector machine and so on. On the other hand, Context-Tree Weighting(CTW) algonthm that has been proposed by F.M.J.Willems shows a very good compression performance. Automatic classification method applied to this CTW has been proposed, and it shows very good performance, e.g. DNA analysis. In this paper, we consider the semi-supervised leamng of the document classification for the case where the number of the learning data is not sufficient. Then we propose the semi-supervised learning methods using CTW algonthm. Moreover, the expenmental results using a newspaper data set are shown, and we show the efficiency of proposed methods. |
