This study investigates the influence of interaction mode on the information order in a human-computer natural dialogue. Spoken and written interactions were compared using a real natural language information retrieval system. In two experiments, participants performed several task-oriented dialogue scenarios either with a phone or a Web interface. The goal was to locate restaurants with specific characteristics among these present in a database. A typical information order emerged for restaurant search (food type, location, and price) whatever the dialogue mode. However, the amount of information was higher in the written than in the spoken mode. The structure of utterances in service dialogue appears to follow canonical ordering. This order can be used for optimize the system feedback.
