Abstract
Emotion recognition in conversation(ERC)has attracted growing attention in recent years as a result of the advancement and implementation of human-computer interface technologies.In this paper,we propose an emotional inertia and contagion-driven dependency modeling approach(EmotionIC)for ERC tasks.Our EmotionIC consists of three main components,i.e.,identity masked multi-head attention(IM-MHA),dialogue-based gated recurrent unit(DiaGRU),and skip-chain conditional random field(SkipCRF).Compared to previous ERC models,EmotionIC can model a conversation more thoroughly at both the feature-extraction and classification levels.The proposed model attempts to integrate the advantages of attention-and recurrence-based methods at the feature-extraction level.Specifically,IMMHA is applied to capture identity-based global contextual dependencies,while DiaGRU is utilized to extract speaker-and temporal-aware local contextual information.At the classification level,SkipCRF can explicitly mine com-plex emotional flows from higher-order neighboring utterances in the conversation.Experimental results show that our method can significantly outperform the state-of-the-art models on four benchmark datasets.The ablation studies confirm that our modules can effectively model emotional inertia and contagion.
