Resource-Adaptive Action Planning in a Dialogue System for Repair Support

. For reasonable application in critical domains dialogue systems not only have to pay attention to user knowledge and dialogue goals but they also have to adapt their dialogue behaviour to current limitations of the user's cognitive processing capabilities. In case of a help system the point of concern is on the one hand the aspect as to what kind of help is appropriate for the user P (What to do?). This action planning has to take into account P's resource limitations like time pressure and working memory load. On the other hand the system's utterances should also be adapted to P's language processing capabilities (What to say -- and how?). This work presents primarily approaches to adaptive action planning. Its interaction with dialogue planning is outlined. 1 Introduction 1.1 Issues In the field of human-computer-communication considerable progress has been made since the first approaches to user modelling in adapting system behaviour to individual user knowledge and current dial..
