It is generally said that tens of thousands or more of training data are required to obtain high accuracy in text processing tasks using deep learning.
However, small amounts of data are available to train the solvers in practical tasks.
In this paper, we propose a method to improve the accuracy of a text classification task.
The method utilizes a data augmentation by exchanging phrases depend the same phrase.
