Event Processing and Stream Reasoning with ETALIS

This thesis presents the ETALIS Language for Events (ELE), a declarative rule-based language for Event Processing (EP) and Stream Reasoning (SR). ELE features a well-defined semantics, and provides strong event processing and reasoning capabilities. In this work we present ELE and show how its EP and SR capabilities have the potential to provide powerful real time intelligence. We provide a prototype implementation of the language, and present evaluation results for a few implemented scenarios.
