Exploiting Multi-Emotion Relations at Feature and Label Levels for Emotion Tagging

The dependence among emotions is crucial to boost emotion tagging. In this paper, we propose a novel emotion tagging method, that thoroughly explores emotion relations from both the feature and label levels. Specifically, a graph convolutional network is introduced to inject local dependence among emotions into the model at the feature level, while an adversarial learning strategy is applied to constrain the joint distribution of multiple emotions at the label level. In addition, a new balanced loss function that mitigates the adverse effects of intra-class and inter-class imbalance is introduced to deal with the imbalance of emotion labels. Experimental results on several benchmark databases demonstrate the superiority of the proposed method compared to state-of-the-art works.
