Such issues as dialog structure, dialog act analysis, turn segmentation (that is, segment a turn into several sentences or utterance units) have not yet been successfully resolved, especially in spoken Chinese dialog. Our corpus consists of 94(more than 3,000 turns) telephone-recorded Chinese humanhuman dialogues in the domain of room reservation.In this paper, we give some results of analysis of the corpus. We concentrate on four important phenomena in spoken Chinese: sentences hyperbaton, sentence fragment, speech repair, cue phrase. These four phenomena, we think, are essential for turn segmentation as well as other problems.
