Large-scale, situation-driven and quality-aware event marketplace: the concept, challenges and opportunities.

ABSTRACTThis poster presents a novel approach for large scale, context-driven and quality-aware distributed event processing. We present the conceptual architecture of the system and mapping in an ongoing use-case deployment. In particular we give examples of the usage of the platform in this use-case. Additionally, we present the challenges and opportunities of such an architecture, namely logic-based CEP, combined with historic events and background knowledge, elastic run-time configuration in the cloud for CEP as a Service, maintenance of QoS for events, a unified language for reasoning and querying current and historic events. The approach leads to an Event Marketplace, a platform for mediating between event providers and (complex) event consumers in very large and heterogeneous environments.
