Extending Complex Event Processing to Graph-structured Information
Gala Barquero, Loli Burgueño, Javier Troya, Antonio Vallecillo · 2018
Complex Event Processing (CEP) is a powerful technology in realtime distributed environments for analyzing fast and distributed streams of data, and deriving conclusions from them. CEP permits defining complex events based on the events produced by the incoming sources in order to identify complex meaningful circumstances and to respond to them as quickly as possible. However, in many situations the information that needs to be analyzed is not structured as a mere sequence of events, but as graphs of interconnected data that evolve over time. This paper proposes an extension of CEP systems that permits dealing with graph-structured information. Two case studies are used to validate the proposal and to compare its performance with traditional CEP systems. We discuss the benefits and limitations of the CEP extensions presented.
