Abstract:

The main functions of situation assessment were analysed.That the kernel and start point of the situation assessment system is the event detection was brought forward.The situation assessment knowledge representation using the Bayesian networks and the time/spatial knowledge representation in the situation assessment were discussed.The steps to construct a Bayesian networks for situation assessment were presented,and the layers of events in the situation assessment system were analysed. Finally,the process of how to use the Bayesian networks for situation assessment was showed by an example.

Key words:  situation assessment, Bayesian networks, event detection, knowledge representation
