BiCEP is a new project being started at the University of Coimbra to benchmark Complex Event Processing systems (CEP). Although BiCEP is still in the early stages, we list here some of the design considerations that will drive our future work and some of the metrics we plan to include in the benchmark.

The convergence of sensors, smart objects, wearable devices, communications (Internet, wireless, mobile), intelligent information processing (filtering, feature extraction, feature selection), and information fusion/detection technologies, has given birth to a new field of study and applications, called Internet of Things (IoT), Smart Planet, Cyber Physical Systems (CPS), Smart Sensing or 物联网 (...

Complex Event Processing (CEP) deals with processing of continuously arriving events with the goal of identifying meaningful patterns (complex events). In existing stream database approaches, CEP is manly concerned by temporal relations between events. This paper advocates for a knowledge-rich CEP with Stream Reasoning capabilities. Secondly, we address the problem of revision in event processi...

Complex Event Processing (CEP) is a stream processing model that focuses on detecting event patterns in continuous event streams. While the CEP model has gained popularity in the research communities and commercial technologies, the problem of gracefully degrading performance under heavy load in the presence of resource constraints, or load shedding, has been largely overlooked. CEP is similar ...

Several application domains involve detecting complex situations and reacting to them. This asks for a Complex Event Processing (CEP) middleware specifically designed to timely process large amounts of event notifications as they flow from the peripheral to the center of the system, to identify the composite events relevant for the application. To answer this need we designed T-Rex, a new CEP m...

Complex Event Recognition (CER) applications exhibit various types of uncertainty, ranging from incomplete and erroneous data streams to imperfect complex event patterns. We review CER techniques that handle, to some extent, uncertainty. We examine both automata-based techniques, which are the most often, and logic-based ones, which are less frequently used. A number of limitations are identifi...
