Abstract:

We have developed an application-independent toolkit, called Collagen, based on the SharedPlan theory of collaborative discourse, in which interaction histories are hierarchically structured according to a user\'s goals and intentions. We have used Collagen to implement an example collaborative interface agent with discourse processing, but not natural language understanding. In this paper, we concentrate on how a segmented interaction history supports user orientation, intelligent assistance, and transformations, such as returning to earlier points in the problem solving process and replaying segments in a new context.
