| Abstract(in English) | Although the terms of service (ToS) tend to be skipped because of their large number of articles, some of them may be potentially unfair to users. In this paper, we propose a method for automatically detecting unfair articles in ToS so that users can check them efficiently. The previous studies used linear SVM for the automatic detection in Japanese ToS, and it performed undersampling to eliminate imbalance in the training data to improve classification performance. However, the classification performance is not satisfactory. In this paper, we use GAN-BERT, a learning model that extends BERT with semi-supervised GANs, to use a small number of labeled ToS and easily available unlabeled ToS for training, and show higher classification performance. |
