Big Data brings with it new and exciting challenges to complex event processing. Large volumes of simple events that stream in high velocity to our processing stations from a variety of sources call for rethinking traditional methods of processing complex events. In this talk we shall explore the interesting phenomenon of event streams that are produced by processes, e.g., bus data that is governed by bus routes or real-time positioning system tracking patients in an outpatient clinic. The talk shall answer some of the related interesting questions: how do we discover the rules that govern event creation? how do we use such rules to optimize complex event processing? and suggest directions for future research. The talk will be accompanied by examples of urban transportation in Dublin (the INSIGHT European project) and patient visits to Dana-Farber Cancer Institute (DFCI), a large outpatient cancer in the US.
