Initiative conflicts in task-oriented dialogue
نویسندگان
چکیده
An initiative conflict is an overlap of speech in which both conversants try to steer the conversation in different directions. In this paper, we investigate how conversants in human-human dialogue deal with such conflicts. First, in investigating why initiative conflicts occur, we find that the offsets of the utterances involved in initiative conflicts tend to be very short, and that initiative conflicts seem more likely to occur when one of the conversants has an urgent conversational goal. These findings strongly suggest that initiative conflicts are unintentional collisions and that conversants try to prevent them from even occurring, unless there is an urgent reason. Second, in investigating how initiative conflicts are resolved, we find that the overlaps tend to last less than two syllables, that volume correlates with who wins initiative conflicts, and that for longer overlaps, the volume of the winner increases in the second half of the overlaps. These findings strongly suggest that initiative conflicts are quickly resolved through an interactive process, using volume as one of the devices. Third, we find that after an initiative conflict is resolved, the winner sometimes repeats the words involved in the overlap; and this happens more when the overlap is more likely to interfere with the other conversant’s understanding. These findings will help us build next-generation mixed-initiative spoken dialogue systems that are natural and efficient to use. 2009 Elsevier Ltd. All rights reserved.

Avoiding and Resolving Initiative Conflicts in Dialogue
In this paper, we report on an empirical study on initiative conflicts in human-human conversation. We examined these conflicts in two corpora of task-oriented dialogues. The results show that conversants try to avoid initiative conflicts, but when these conflicts occur, they are efficiently resolved by linguistic devices, such as volume.
متن کاملUsing Protocols to Model Mixed Initiative Interaction
We are interested in the mechanisms needed to control computer initiative to allow systems to engage in mixedinitiative task-oriented/planning (TOP) dialogues. A TOP dialogue is about an ongoing task that may require replanning during its execution. We discuss our model for initiative and motivate the use of protocols. Finally, we present some protocol rules and analyze a TOP dialogue exchange ...

In this paper, we examine mechanisms for automat ic dialogue initiative setting. We show how to incorporate initiative changing in a task-oriented human-compute r dialogue system, and we evaluate the effects of initiative both analytically and via compute r -compute r dialogue simulation. 1 Motivation: Initiative in Task-Oriented Dialogues Efficient human-compute r dialogue requires immediate u...
متن کاملTowards understanding mixed-initiative in task-oriented dialogues
Mixed-initiative in dialogue does not mean that either speaker is free to take the lead in the conversation at any time. Rather, who can show initiative, and when, is restricted. In this paper, we define initiative and control as two levels of dialogue phenomena, and give further evidence for our theory of restricted initiative that control belongs to the initiator of a discourse segment. We sh...
متن کاملControl in task-oriented dialogues
In this paper, we explore the mechanisms by which conversants control the direction of a dialogue. We find further evidence that control in task-oriented dialogues is subordinate to discourse structure. The initiator of a discourse segment has control; the non-initiator can contribute to the purpose of the segment, but this does not result in that person taking over control. The proposal has im...
