Commitment-based Natural Language Interface System for Robots

摘要

In this paper, we first discuss how the commitment in human-robot natural language conversation is important and the lack of the commitment leads to breakdowns in conversation. Then, we propose a human-robot conversation model, which takes the breakdown into consideration. We implemented a natural language interface system of a mobile robot, based on the proposed conversation model. Then, we conducted experiments with subjects and confirmed that the proposed interface system provides more natural conversation between human and robot with fewer breakdowns.
