Efficient Temporal Datalog Materialisation for Composite Event Recognition

arXiv:2605.02488v2 Announce Type: replace Abstract: Several applications demand the timely detection of critical situations, such as threats to safety and transparency, over high-velocity streams of symbolic events. This demand has motivated the development of (i) event specification languages, which define composite events via temporal patterns over simpler events, and (ii) stream reasoning frameworks, evaluating patterns expressed in these languages. However, event specification languages are typically studied in isolation, complicating their comparison in terms of expressivity and obscuring

Why this matters
Why now

The continuous evolution of AI and real-time data processing necessitates more efficient and robust methods for identifying complex patterns in high-velocity data streams.
