Research has focused on classification of emotions and discovery of emotion causes. Through analyses, one not only can discover emotional reactions of the general public towards brands/products/services, political topics, and social issues, but also emotion/mood states of individuals, which may indicate depressions, anti-social behaviors, and suicidal intentions. Recently, studies have moved from pure text-based analysis to multi-modal data based analysis. With the popularity of chatbots, the research in the area has been expanded to active generation of emotional and empathetic utterances/responses in human-machine conversations. Humans are emotional beings. Any communications with them should be carried out with appropriate emotions.
Applications of emotional chatbots include customer care, personal companion and service bots, and even self-driving cars. Beyond these, it is also important to endow chatbots the ability to learn by themselves during conversations to become better and better with no external supervision.
