CER is giving the Complex Event Recognition and Forecasting Tutorial at KR 2021
We will present the formal methods for Complex Event Recognition (CER), i.e. models based on automata and computational logic, as they have been developed in the database, distributed systems, and artificial intelligence communities. For each of these models, we will present the reasoning algorithms that support on-line event recognition, as well as event forecasting, i.e. the computation of future intervals in which an event is likely to happen. To illustrate the reviewed approaches we will use a real-world use case from the INFORE project: complex event recognition for maritime situational awareness.
