Understanding and simulating narratives in the context of information systems

A modelling tool is described, which integrates simulation, plan recognition and knowledge discovery modules to help the specification and implementation of complex information systems. The tool is based on the concept of plots of narratives, defined as partially ordered sets of events leading to the achievement of various (possibly interconnected) goals. Based on a formal description of the behaviour of the participating agents, a planning algorithm is used to simulate valid plots of narratives. Plan recognition and knowledge discovery techniques are used to detect typical behaviours in observed plots. The framework also contains modules for presenting plots as texts, graphs and 3D animations, so as to provide informative and easy-to-handle user interfaces.
