  AbstractURLBibTeXEndNoteBibSonomy

  Complex Event Processing (CEP) is concerned with timely detection of complex events within multiple streams of atomic occurrences, and has useful applications in areas including financial services, mobile and sensor devices, click stream analysis and so forth. In this chapter, we present ETALIS Language for Events. It is an expressive language for specifying and combining complex events. For this language we provide both a syntax as well as a clear declarative formal semantics. The execution model of the language is based on a compilation strategy into Prolog. We provide an implementation of the language, and present experimental results of our running prototype. Further on, we show how our logic rule-based approach compares with a non-logic approach in respect of performance.

• Semantic Complex Event Reasoning -- Beyond Complex Event Processing Stojanovic, Nenad; Stojanovic, Ljiljana; Anicic, Darko; Ma, Jun; Sen, Sinan; St{ü}hmer, Roland D. Fensel (ed.) (2011). 253–279.

  AbstractURLBibTeXEndNoteBibSonomy

  Complex event processing is about processing huge amounts of information in real time, in a rather complex way. The degree of complexity is determined by the level of the interdependencies between information to be processed. There are several more or less traditional operators for defining these interdependencies, which are supported by existing approaches and the main competition is around the speed (throughput) of processing. However, novel application domains like Future Internet are challenging complex event processing for a more comprehensive approach: from how to create complex event patterns over the heterogeneous event sources (including textual data), to how to efficiently detect them in a distributed setting, including the usage of background knowledge. In this chapter we present an approach for intelligent CEP (iCEP) based on the usage of semantic technologies. It represents an end-to-end solution for iCEP starting from the definition of complex event patterns, through intelligent detection, to advanced 3-D visualization of complex events. At the center of the approach is the semantic model of complex events that alleviates the process of creating and maintaining complex event patterns. The approach utilizes logic-based processing for including domain knowledge in the complex event detection process, leading to complex event reasoning. This approach has been implemented in the web-based framework called iCEP Studio.

  AbstractURLBibTeXEndNoteBibSonomy

  Rich Internet Applications provide, in conjunction with Internet push technologies, a powerful framework to bring use cases formerly reserved to server applications to the client, and to ease their use. In this paper we present a novel approach of monitoring and processing event streams directly in the browser. Our proposed general-purpose framework aims at the design of event-driven, reactive and adaptive Rich Internet Applications. We propose to interweave complex event processing with declarative rule execution directly on the client-side. Our work is based on a novel event-condition-action rule language tailored to the needs of Rich Internet Applications as well as algorithms capable of detecting complex events and executing rules. The whole approach will be illustrated by means of an example originating from the field of algorithmic stock trading.

• Event-driven Reactivity: A Survey and Requirements Analysis Schmidt, Kay-Uwe; Anicic, Darko; St{ü}hmer, Roland (2008).

  AbstractURLBibTeXEndNoteBibSonomy

  Despite the huge popularity of event processing nowadays, there is a big gap between the potential usefulness of event-driven processing and the current state of the practice. One of the main reasons is the lack of a comprehensive conceptual model for the event-triggered reactivity and the corresponding framework for its management. In this paper we survey the current state of the art in event-driven architecture with special focus on event and action processing. We describe the prerequisites of a completely novel conceptual model for describing reactivity that is more close to the way people react on events: based on the ability to identify the context during which active behavior is relevant and the situations in which it is required. This approach opens a completely new view on the event processing as the way for managing a very valuable knowledge asset of every enterprise - knowledge how to react (make decisions) in event-driven situations

• From Business Rules to Application Rules in Rich Internet Applications Schmidt, Kay-Uwe; St{ü}hmer, Roland; Stojanovic, Ljiljana (2008). 9(4) 329–340.

  AbstractURLBibTeXEndNoteBibSonomy

  The increase of digital bandwidth and computing power of personal computers as well as the rise of the Web 2.0 came along with a new web programming paradigm: Rich Internet Applications. On the other hand, powerful server-side business rules engines appeared over the last years and let enterprises describe their business policies declaratively as business rules. This paper addresses the problem of how to combine the business rules approach with the new programming paradigm of Rich Internet Applications. We present a novel approach that reuses business rules for deriving declarative presentation and visualization logic. In this paper we introduce a rule-driven architecture capable of executing rules directly on the client by implementing the Rete algorithm. We propose to use declarative rules as platform independent language describing the application and presentation logic. By means of AJAX we exemplarily show how to use client-side executable rules for adapting the user interface of Rich Internet Applications. We call our approach ARRIA: Adaptive Reactive Rich Internet Applications. In order to show the usability of our approach we explain our approach based on an example taken from the financing sector.

  AbstractBibTeXEndNoteBibSonomyDownload

  State of the art event-driven Rich Internet Applications (RIAs) rely on technologies like the Comet architecture or polling strategies like RSS feeds to provide a basic infrastructure for transporting events to the Web client. However, such RIAs provide no means for further processing of these events. This gap will be closed by the approach proposed in this thesis. The approach combines complex event processing and rule execution with an ontology-based object model directly on the Web client. A framework is proposed, built on declarative rules for achieving reactive and adaptive RIAs. The work consists of a novel event-condition-action rule language tailored to the needs of RIAs as well as a client-side rule engine capable of detecting complex events and executing rules.

• Blending Complex Event Processing with the RETE Algorithm Schmidt, Kay-Uwe; St{ü}hmer, Roland; Stojanovic, Ljiljana D. Anicic, C. Brelage, O. Etzion, N. Stojanovic (eds.) (2008). (Vol. Vol-412)

  AbstractURLBibTeXEndNoteBibSonomy

  Modern event-driven applications implement sophisticated and highly specialized algorithms for detecting and correlating events from event streams or clouds. The correlation logic and resulting actions are declaratively defined as EA (event action) rules. An EA language allows the definition of complex correlation rules with the help of logical, temporal, content-based and other operators. On the other hand, production rule systems provide a declarative means to express and compute CA (condition action) rules. CA rules define constraints. The most prominent scientific and commercial production rule systems rely on the RETE algorithm in order to efficiently compute CA rules. As the industry is on the way towards a loosely coupled service-oriented and eventdriven architecture, there is a high demand for an integrated solution of computing ECA (event condition action) rules. In this paper we give a survey of already finished as well as ongoing research in the field of combining event processing algorithms with the RETE algorithm. We compare the different approaches and present our approach of combining SnoopIB, a specialized event detection algorithm, with the RETE algorithm.
