ACM Transactions on Internet Technology (TOIT) - Special Issue on Event Recognition, Volume 14 Issue 1, July 2014

Section: Special Issue on Event Recognition

Event Recognition Challenges and Techniques: Guest Editors' Introduction
Alexander Artikis, Avigdor Gal, Vana Kalogeraki, Matthias Weidlich
Article No.: 1
DOI: 10.1145/2632220

Approximate Semantic Matching of Events for the Internet of Things
Souleiman Hasan, Edward Curry
Article No.: 2
DOI: 10.1145/2633684

Event processing follows a decoupled model of interaction in space, time, and synchronization. However, another dimension of semantic coupling also exists and poses a challenge to the scalability of event processing systems in highly semantically...

PADUA: Parallel Architecture to Detect Unexplained Activities
Cristian Molinaro, Vincenzo Moscato, Antonio Picariello, Andrea Pugliese, Antonino Rullo, V. S. Subrahmanian
Article No.: 3
DOI: 10.1145/2633685

There are numerous applications (e.g., video surveillance, fraud detection, cybersecurity) in which we wish to identify unexplained sets of events. Most related past work has been domain-dependent (e.g., video surveillance, cybersecurity) and has...

Adaptive Speculative Processing of Out-of-Order Event Streams
Christopher Mutschler, Michael Philippsen
Article No.: 4
DOI: 10.1145/2633686

Distributed event-based systems are used to detect meaningful events with low latency in high data-rate event streams that occur in surveillance, sports, finances, etc. However, both known approaches to dealing with the predominant out-of-order...

Decentralized Fault-Tolerant Event Correlation
Gregory Aaron Wilkin, Patrick Eugster, K. R. Jayaram
Article No.: 5
DOI: 10.1145/2633687

Despite the prognosed use of event correlation techniques for monitoring critical complex infrastructures or dealing with disasters in the physical world, little work exists on making event correlation systems themselves tolerant to failure....

MCEP: A Mobility-Aware Complex Event Processing System
Beate Ottenwälder, Boris Koldehofe, Kurt Rothermel, Kirak Hong, David Lillethun, Umakishore Ramachandran
Article No.: 6
DOI: 10.1145/2633688

With the proliferation of mobile devices and sensors, complex event proceesing (CEP) is becoming increasingly important to scalably detect situations in real time. Current CEP systems are not capable of dealing efficiently with highly dynamic...

Efficient Stream Provenance via Operator Instrumentation
Boris Glavic, Kyumars Sheykh Esmaili, Peter M. Fischer, Nesime Tatbul
Article No.: 7
DOI: 10.1145/2633689

Managing fine-grained provenance is a critical requirement for data stream management systems (DSMS), not only for addressing complex applications that require diagnostic capabilities and assurance, but also for providing advanced functionality,...
