Identifying Repair Targets in Action Control Dialogue

This paper proposes a method for dealing with repairs in action control dialogue to resolve participants’ misunderstanding. The proposed method identifies the repair target based on common grounding rather than surface expressions. We extend Traum’s grounding act model by introducing degree of groundedness, and partial and mid-discourse unit grounding. This paper contributes to achieving more natural human-machine dialogue and instantaneous and flexible control of agents.
