| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | The Text Classification problem has been investigated by various techniques, such as a vector space model, a support vector machine and so on. On the other hand, the Context-Tree Weighting algorithm has been proposed as an outstanding data compression method, and the technique of applying this to the text classification has been proposed. In this paper, we consider the classification method using the Context-Tree Weighting algorithm. Then we examine the text classification method which assumed that each document of a category arises from one stochastic model. Moreover, the experimental results using a newspaper data set are shown, and we show the efficiency of the text classification using CTW. | |
