Enhancing Computer Chat: Toward a Smooth User-Computer Interaction.

Human-computer interaction (HCI) has fundamentally chan- ged computing. The ubiquity of HCI can be seen in several kinds of application areas, such as text editing, hypertext, gesture recognition, and the like. Since HCI is concerned with the joint performance of tasks by humans and machine, human-computer conversational interaction plays a central role when trying to bring the computer behavior closer to the human conversational behavior. In this paper we introduce our idea of modeling computer chat based on the observed "critical" behavior of the structure of human chat. [ABSTRACT FROM AUTHOR]
