Abstract

This research examined the response selection method of an interview-based dialog system that obtains the user’s information by the chat-like conversation. In the interview dialog, the system should ask about the subject that the user is interested in to obtain the user’s information efficiently. In this paper, we proposed the method to select the system’s utterance based on the user’s emotion to a focus detected from the user’s utterance. We prepared the question types corresponding to the semantic orientation, such as the positive, neutral, and negative. The focus was detected by the CRF, and the question type was estimated from the user’s utterance and the system’s previous utterance.
