Combining Expression and Content in Domains for Dialog Managers

By Bernd Ludwig, Günther Görz and Heinrich Niemann


We present work in progress on abstracting dialog managers from their domain in order to implement a dialog manager development tool which takes (among other data) a domain description as input and delivers a new dialog manager for the described domain as output. Thereby we will focus on two topics; firstly, the construction of domain descriptions with description logics and secondly, the interpretation of utterances in a given domain. 1 Introduction Current research on dialog management is guided by two different ideas: firstly, to describe the discourse structure that the dialog manager is able to handle by a finite automaton using possible utterances as transitions (e.g. [10]), and secondly, to view the detection of discourse structure as a parameter estimation problem and to use statistical models for the description of discourse structure (e.g. [12], [8]). Some serious problems remain with each of these approaches: first of all, they do not integrate a user model. The finite sta..
