Uncertainty-Aware Event Analytics over Distributed Settings.

N. Giatrakos et al. - Proceedings of the 13th ACM International Conference on Distributed and Event-based Systems. ACM - ACM, 2019


In complex event processing (CEP), simple derived event tuples are combined in pattern matching procedures to derive complex events (CEs) of interest. Big Data applications analyze event streams online and extract CEs to support decision making procedures. At massive scale, such applications operate over distributed networks of sites where efficient...

Incremental Event Calculus for Run-Time Reasoning.

Tsilionis, Artikis, Paliouras - Proceedings of the 13th ACM International Conference on Distributed Event-Based Systems - DEBS, 2019.


We present a system for online, incremental composite event recognition. In streaming environments, the usual case is for data to arrive with a (variable) delay from, and to be retracted/revised by the underlying sources. We propose RTECinc, an incremental version of RTEC, a composite event recognition engine with a formal,...

Interactive Extreme Scale Analytics Towards Battling Cancer

N. Giatrakos et al. - IEEE Technology and Society Magazine - vol. 38, no. 2, pp. 54-61, June 2019.


A synergetic understanding of cancer evolution and the effect of combination drug therapies on the disease is the cornerstone for developing effective personalized treatments, which can radically improve patients’ well-being and their quality of (work and social) life. By extension, improving the treatment of patients indirectly enhances the quality of...

Functional Geometric Monitoring for Distributed Streams

Vasilis Samoladas and Minos Garofalakis. - Proceedings of EDBT'2019 - Lisbon, Portugal, March 2019


We introduce Functional Geometric Monitoring (FGM), a substantial theoretical and practical improvement on the core ideas of Geometric Monitoring. Instead of a binary constraint, each site is provided with a non-linear function, which, applied to its local summary vector, projects it to a real number. The sites collectively monitor the...
