Abstract

The main aim of this paper is to demonstrate the effectiveness of using Situation Calculus in Task Modelling. The motivation for this approach is to enable a runtime adaptable task model to be used in the provision of the most appropriate user interfaces, according to circumstance. The task model and meta-reasoning model may both be specfied in the Situation Calculus, which permits reasoning to occur over couterfactual situations and without exhaustive state enumeration. A task flow editor with input from the formal model is demonstrated and the approach is described using a medical process case study.
