Abstract

Human discourse appears coherent when it reflects coherent human thought. However, computers do not necessarily store or process information in the same way that people do and, therefore, cannot rely on the structure of their reasoning for the structure of their dialogues. Instead, computer-generated conversation must rely on some other mechanism for its organisation. In this paper, we discuss one such mechanism. We describe a template that provides a guide for conversation. The template is built from schemata representing discourse convention. As goals arrive from the problem solver they are added to the template. Because accepted discourse structures are used to connect a new goal to the existing template, goals are organised into sub-groups that follow conventional, coherent patterns of discourse. We present JUDIS, an interface to a distributed problem solver that uses this approach to organise dialogues from an incoherent stream of goals.
