Description

One of main goals of the Future Internet is to “dynamically and proactively support the
operations of businesses organisations and the everyday life of citizens and in a seamless and natural fashion”¹. It would require the transition from a passive system in which users initiate activities (like Internet is now), to an active environment in which associated software agents find, organize and display information/services on behalf of users.
In the nutshell of this process is the ability of a Future Internet system (i.e., an agent or a service) to sense and respond on the billions of signals² coming from different sources in different forms. For example, an interesting triggering event can be the non-existence of a signal that regularly appears in a context of a service’s execution. Such an event can influence the execution of another service, which can result in another event. Even more, the combination of these events in a particular context can be treated as an event (complex event), relevant for the execution of another service(s).

In the networked services supply chain, that will characterize Future Internet, every service produces many events that might be relevant for other services. It is clear that all these influences, due to their ad-hoc nature, cannot be defined in advance explicitly. If there would be such an explicit approach, it would enable querying for relevant events. However, realworld
reactivity requires a kind of publish-subscribe mechanism, that enables pushing relevant events to interesting parties. It means that the actual data flow (and not predefined workflows) will determine the reactive nature of a Future Internet system.
Moreover, the events seem to be ideal glue that connects two key ingredients of the Future Internet: Internet of Things and Internet of Services. Indeed, IoT can be seen as the producer of events that are processed in the IoS.
On the other side, event-based systems are now gaining increasing momentum as witnessed by current efforts in areas including event-driven architectures, business process management and modelling, Grid computing, Web services notifications, and message-oriented middleware. They become ever important in various application domains, ranging from traditional business applications, like supply-chain management, to the entertainment industry, like on-line gaming applications. However, the current status of development is just the top of the iceberg compared with the impact that event processing could achieve, as already reported by market research companies. Indeed, existing approaches are dealing primarily with the syntactical (but very scalable) processing of low-level signals and primitive actions, which usually goes with an inadequate treatment of the notions of time, context or concurrency (e.g., synchronization). For example, some of the current event processing products are descendents of the active database research that misses efficient (formal) handling of termination, priority ordering, and confluence in rule bases.

Hence, the realisation of the reactive nature of the Future Internet requires new models, methods and tools for the efficient event processing: their representation, acquisition, aggregation and consumption. Especially important is the processing of events on a higher abstraction level, by combining them in a specific context: time, space, semantics – so called complex event processing (CEP). It includes finding and defining event patterns from the low level events, aggregating and correlating events to build business level events.

AI and especially symbolic (e.g., logic-based) approaches provide native background for the (formal) representation of the above mentioned missing concepts, enabling evolution from event processing systems into intelligent reactive systems. The work done in temporal logic, spatial reasoning, knowledge representation, ontologies, etc enables more declarative representation of events and actions and their semantic processing. Contextual reasoning can support complex event prediction. Transactional logic can be used for ensuring the consistency between highly dependent processes in a formal way.
Finally, Complex Event Processing has already been recognized as a natural extension of SOA under the term SOA2.0 or Advanced SOA, as depicted in Figure1³.
