Survey on Emotion Recognition in Conversation

Emotion recognition in conversation（ERC） is a hot research topic in the field of emotion computing, which aims to detect the emotion category of each discourse during the dialogue. It has important research significance for dialogue understanding and dialogue generation. At the same time, it has a wide range of practical application value in many fields, such as social media analysis, recommendation system, medical treatment and human-computer interaction. With the continuous innovation and development of deep learning technology, emotion recognition in conversation has attracted more and more attention from academia and industry. At this stage, it is necessary to summarize these research results in an overview article in order to better carry out follow-up work. The research results in this field are comprehensively sorted out from the perspectives of problem definition, problem approach, research methods, and mainstream datasets, and the development of dialogue emotion recognition tasks is reviewed and analyzed. Compared with video and audio, dialogue text contains more information. Therefore, this paper focuses on combing the text dialogue emotion recognition methods, especially the methods based on deep learning. Finally, based on the current research status, this paper summarizes the open problems existing in the field of dialogue emotion recognition and the development trend in the future.
