The purpose of the special parasession on "Interactive Man/Machine Discourse" is to discuss some critical issues in the design of (computer-based) interactive natural language processing systems. This panel will be addressing the question of how the purpose of the interaction, or "problem context" affects what is said and how it is interpreted. Each of the panel members brings a different orientation toward the study of language to this question. | Interactive Discourse Influence of Problem Context Panel Chair s Introduction Barbara Grosz SRI International The purpose of the special parasession on Interactive Man Machine Discourse is to discuss some critical issues in the design of computer-based interactive natural language processing systems. This panel will be addressing the question of how the purpose of the interaction or problem context affects what is said and how it is interpreted. Each of the panel members brings a different orientation toward the study of language to this question. My hope is that looking at the question from these different perspectives will expose issues critical to the study of language in general and to the construction of computer systems that can communicate with people in particular. Of course the issue of the influence of problem context is separable from the issue of how one might get a computer system to take into account the effects of this context and yes even whether that is possible . My hope is that those on the panel who are concerned with the construction of computer-based natural language processing systems will address some of the issues of how and that all of the panelists will consider the prior questions of what effects there are and what general principles underlie how the problem context influences a dialogue. There are two separate aspects to the problem context that influence the participants expectations and hence their utterances 1 the function of the discourse and 2 the domain of discourse. Function This aspect of the problem context concerns why the speaker and hearer are communicating and their relative roles in the communication. Casual conversations classroom discussions task-oriented dialogues and stories have very different functions. Although it is most reasonable to consider computer systems as participating in a restricted kind of dialogue namely a dialogue which arises from aiding a person in the solution of some problem it is still clear that
