Empirical Studies Of Discourse Representations For Natural Language Interfaces

چکیده
We present the results from a series of experiments aimed at uncovering the discourse structure of man-machine communication in natural language (Wizard of Oz experiments). The results suggest the existence of different classes of dialogue situations, requiring computational discourse representations of various complexity. Important factors seem to be the number of different permissible tasks in the system and to what extent the system takes initiative in the dialogue. We also analyse indexical expressions and especially the use of pronouns, and suggest a psychological explanation of their restricted occurrence in these types of dialogues.

Application-Dependent Discourse Management for Natural Language Interfaces: An Empirical Investigation
This paper presents results from a refined analysis of a series of Wizard of Oz-experiments with focus on discourse management. The study is part of a larger project aimed at designing a general natural language interface. It is argued that a natural language interface needs different referent res olution mechanisms for different combinations of background systems and scenarios. I present thre...

When developing natural language interfaces, it is important to know the characteristics of the language used. We have developed a set of tools for conducting human-computer natural language dialogue simulations (Wizard of Oz experiments) and for analyzing the data obtained. We report methods used and results obtained from a series of such experiments. The focus of the study was on occasional u...

We discuss current approaches to the development of natural language dialogue systems, and claim that they do not sufficiently consider the unique qualities of man-machine interaction as distinct from general human discourse. We conclude that empirical studies of this unique communication situation is required for the development of user-friendly interactive systems. One way of achieving this i...
