An empirical study on referent identification requests or referring actions in multi-modal dialogues is reported. Through the examination of a corpus obtained by experiments in which experts explained the installation of a telephone with answering machine features in two situations, spoken-mode dialogue and multi-modal dialogue, referring actions in multi-modal dialogues were well analyzed and compared with those in spoken-mode dialogues from two perspectives: information communicated and the style of goal achievement. One of the findings obtained through this study is that the availability of pointing actions in multi-modal dialogues reduces the amount of information verbally communicated. The kind of information reduced from the spoken-mode situation depends on contextual status. This fact suggests that pointing actions are different from actions that communicate a specific type of information such as object location and figures. Rather, they are actions to activate the object referred to in the interlocutor's mental space. As communicating information on an object plays the same role in referring actions, pointing actions and verbal communication can be compared in this standpoint. Another finding is that in spoken-mode dialogues, as compared to multi-modal dialogues, the speakers realize identification requests as a series of fine-grained steps, and try to achieve them step by step with frequent confirmation.
