Online Learning Probabilistic Event Calculus Theories in Answer Set Programming
Nikos Katzouris, Alexander Artikis, Georgios Paliouras
Complex Event Recognition (CER) systems detect event occurrences in streaming time-stamped input using predefined event patterns. Logic-based approaches are of special interest in…
Online Event Recognition from Moving Vehicles: Application Paper
Efthimis Tsilionis, Nikolaos Koutroumanis, Panagiotis Nikitopoulos +2
We present a system for online composite event recognition over streaming positions of commercial vehicles. Our system employs a data enrichment module, augmenting the mobility dat…
Composite Event Recognition for Maritime Monitoring
Manolis Pitsikalis, Alexander Artikis, Richard Dreo +3
Maritime monitoring systems support safe shipping as they allow for the real-time detection of dangerous, suspicious and illegal vessel activities. We present such a system using t…
Wayeb: a Tool for Complex Event Forecasting
Elias Alevizos, Alexander Artikis, Georgios Paliouras
Complex Event Processing (CEP) systems have appeared in abundance during the last two decades. Their purpose is to detect in real-time interesting patterns upon a stream of events…
Semi-Supervised Online Structure Learning for Composite Event Recognition
Evangelos Michelioudakis, Alexander Artikis, Georgios Paliouras
Online structure learning approaches, such as those stemming from Statistical Relational Learning, enable the discovery of complex relations in noisy data streams. However, these m…
The Complex Event Recognition Group
Elias Alevizos, Alexander Artikis, Nikos Katzouris +2
The Complex Event Recognition (CER) group is a research team, affiliated with the National Centre of Scientific Research "Demokritos" in Greece. The CER group works towards advance…
