| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | In this study, we try to identify patients' tweets for symptom surveillance using Twitter. This functionality is indispensable for developing a system Identifying disease epidemic. Most previous work employed a supervised machine learning methods. In general, they need a large amount of labeled corpus, which are very expensive to be created. In order to cope with this problem, we proposed a method to automatically acquire training corpus from Twitter by using a typical response to a patient. In this paper, we propose a data augmentation approach that extends a training data for RNN-based patient identifier with those automatically acquired corpus. The method consists of two steps. As the first step, initial parameters of identifier are trained by the automatically required large corpus. As the Second step, they are continuously trained by using a small amount of training corpus annotated manually. By this method, it is possible to effectively combine two kinds of corpus in a manner complementing each other. We experimented to apply the proposed data augmentation method for the training of RNN-based patient identifiers. The result showed the proposed model successfully improved the identification performance over the model without data augmentation. |
