Clarification requests (CRs) in conversa- tion ensure and maintain mutual under- standing and thus play a crucial role in robust dialogue interaction. In this pa- per, we describe a corpus study of CRs in task-oriented dialogue and compare our findings to those reported in two prior studies. We find that CR behavior in task-oriented dialogue differs significantly from that in everyday conversation in a number of ways. Moreover, the dialogue type, the modality and the channel qual- ity all influence the decision of when to clarify and at which level of the ground- ing process. Finally we identify form- function correlations which can inform the generation of CRs.
