Requirements for Natural Language Understanding in a System with Graphic Displays.

摘要

The particular task we explored was that of a decision maker examining and modifying a database using a graphics display. The decision maker is expected to manipulate both the context of the database and the form of the display. This paper presents three aspects of our research on a system that can provide graphically represented information and can talk naturally with a user about that information: description of the methodology that we used in developing and analyzing an extended prototypical dialogue between a user and such a system; portions of our analysis of that dialogue that present both the information obtained and the method of obtaining it; and conclusions about the necessary linguistic and non-linguistic capacities of an intelligent conversational partner, as drawn from the full analysis.
