A sticker-based dialog system considering shared emotions in group chat

Abstract

In this paper, we propose a sticker-based dialog model considering shared emotion in group chats. Previous communication robots support only one-on-one conversations. It, therefore. was difficult for the robot to communicate with multiple people. Opportunities for people to communicate using group chat are increasing with the development of SNS. The dialog system, therefore, must behave properly in a group chat. The proposed model estimates the shared emotion in a group chat and judges the emotion sympathy. Our experiments reveal that the proposed model can estimate the shared emotion in a group chat. Further study, however, is required to construct a dialog system for human-like dialog.
