Emotion Recognition in Conversation: Research Challenges, Datasets, and Recent Advances
It addresses the problem of scalable emotion recognition in conversational data for AI developers and researchers, but is incremental as it synthesizes existing work without introducing novel methods.
The paper reviews the challenges and recent advances in emotion recognition in conversation (ERC), highlighting its importance for human-like AI and applications in healthcare and education, but does not present new experimental results or concrete numbers.
Emotion is intrinsic to humans and consequently emotion understanding is a key part of human-like artificial intelligence (AI). Emotion recognition in conversation (ERC) is becoming increasingly popular as a new research frontier in natural language processing (NLP) due to its ability to mine opinions from the plethora of publicly available conversational data in platforms such as Facebook, Youtube, Reddit, Twitter, and others. Moreover, it has potential applications in health-care systems (as a tool for psychological analysis), education (understanding student frustration) and more. Additionally, ERC is also extremely important for generating emotion-aware dialogues that require an understanding of the user's emotions. Catering to these needs calls for effective and scalable conversational emotion-recognition algorithms. However, it is a strenuous problem to solve because of several research challenges. In this paper, we discuss these challenges and shed light on the recent research in this field. We also describe the drawbacks of these approaches and discuss the reasons why they fail to successfully overcome the research challenges in ERC.
