Conjunctive Queries with Theta Joins Under Updates
Muhammad Idris, Martín Ugarte, Stijn Vansummeren +2
Modern application domains such as Composite Event Recognition (CER) and real-time Analytics require the ability to dynamically refresh query results under high update rates. Tradi…
An information-theoretic approach to self-organisation: Emergence of complex interdependencies in coupled dynamical systems
Fernando Rosas, Pedro A. M. Mediano, Martin Ugarte +1
Self-organisation lies at the core of fundamental but still unresolved scientific questions, and holds the promise of de-centralised paradigms crucial for future technological deve…
Constant delay algorithms for regular document spanners
Fernando Florenzano, Cristian Riveros, Martin Ugarte +2
Regular expressions and automata models with capture variables are core tools in rule-based information extraction. These formalisms, also called regular document spanners, use reg…
A Second-Order Approach to Complex Event Recognition
Alejandro Grez, Cristian Riveros, Martin Ugarte +1
Complex Event Recognition (CER for short) refers to the activity of detecting patterns in streams of continuously arriving data. This field has been traditionally approached from a…
