Natural language processing tasks targeting the SDGs (Sustainable Development Goals), which have started to influence social structures and corporate philosophy, have recently begun. Because of the lack of language resources, efforts in Japanese were difficult. In this study, we collected Japanese SDGs-related data from materials published by universities and created a data set. And the SDGs classification model was constructed. As the augmentation method, 1. a part-of-speech replacement using the BERT MASK model 2. A reverse translation method in which the English translation using Google transfer was translated into Japanese again was used. Classification was performed using a topic model (LDA etc.) which is a classical machine learning method and BERT etc. which is a deep learning model. The results show the results of the augmentation in the minority data task. Produces relatively high accuracy in a small number of data.
