Moral Judgment is the task of judging whether the action invoked by the input sentence is good or bad from the viewpoint of the morality. In this paper, we propose a new moral judgment system using attention-based distributed representation and co-occurrence information. Compared to the previous methods, the proposed attention-based system can utilize better representation of the input sentence. In addition, the proposed system can take into account not only distributed representation but also co-occurrence information which is effective in this task. The proposed system can be divided into two parts. First one is a distributed representation learning network using attention-based Long Short-Term Memory. Second one is a moral judgment network using distributed representation and co-occurrence information. In the experiments, the proposed system significantly outperforms the other models. Furthermore, we confirmed that attention-based distributed representation and co-occurrence information contribute to the accuracy improvement.
