Composite Event Patterns For Maritime Monitoring

Maritime monitoring systems support safe shipping as they allow for the real-time detection of dangerous, suspicious and illegal vessel activities. We have been developing a composite event recognition system for maritime monitoring in the Event Calculus, allowing both for verification and real-time performance. To increase the accuracy of the system, we have been collaborating with domain experts in order to construct effective patterns of maritime activity. We present some indicative patterns in the Event Calculus, and evaluate them using two forms of real kinematic vessel data.
