The Use of the Pegs Computational Discourse Framework as an Interlingua Representation
Susann LuperFoy, Keith J. Miller · 1997
Our approach to both applications relies on an interlingua representation that encodes properties of the dialogue history, properties of the world of reference and properties of the current state of the discourse only as essential for getting from source language input to target language output. The theoretical discourse framework (based on Heim 1982, Kamp 1981) that underlies the dialogue manager for our spoken dialogue user-interface systems supports the job of extracting and collecting information from the context, and facilitating human-machine language interaction in a multi-user environment. We will present our use of the mode-independent and language-independent ‘discourse interlingua’ representation (LuperFoy 1991) and the adapta* In this paper, we use the term “command and control system” in its broadest sense to mean systems in which a user issues commands to a backend system through the medium of human language.
