  Intention, emotion and action are important elements in human activities.
Modeling the interaction process between individuals by analyzing the
relationships between these elements is a challenging task. However, previous
work mainly focused on modeling intention and emotion independently, and
neglected of exploring the mutual relationships between intention and emotion.
In this paper, we propose a RelAtion Interaction Network (RAIN), consisting of
Intention Relation Module and Emotion Relation Module, to jointly model mutual
relationships and explicitly integrate historical intention information. The
experiments on the dataset show that our model can take full advantage of the
intention, emotion and action between individuals and achieve a remarkable
improvement over BERT-style baselines. Qualitative analysis verifies the
importance of the mutual interaction between the intention and emotion.
