A Rule-Based Language for Complex Event Processing and Reasoning [chapter]

Darko Anicic, Paul Fodor, Sebastian Rudolph, Roland Stühmer, Nenad Stojanovic, Rudi Studer
2010 Lecture Notes in Computer Science  
However logic-based approaches are not optimized for run-time event recognition (as they are mainly query-driven systems).  ...  In this paper, we present an expressive logic-based language for specifying and combining complex events. For this language we provide both a syntax as well as a formal declarative semantics.  ...  Our approach clearly substantiates existing event-driven systems with declarative semantics and the power of knowledge-based event processing.  ...

2007 Proceedings of the 5th international workshop on Middleware for pervasive and ad-hoc computing held at the ACM/IFIP/USENIX 8th International Middleware Conference - MPAC '07  
So, we propose a middleware approach called WComp which federates an event-driven component-oriented approach to compose services for devices.  ...  In such mechanisms, aspects (called Aspects of Assembly) are selected either by the user or by a self-adaptive process and composed by a weaver with logical merging of high-level specifications.  ...  Firstly, it federates an event driven, component based approach to compose web services for devices.  ...

Undoing Event-Driven Adaptation of Business Processes

Sebastien Mosser, Gabriel Hermosillo, Anne-Francoise Le Meur, Lionel Seinturier, Laurence Duchien
2011 2011 IEEE International Conference on Services Computing  
In this paper we bring forward a solution for efficiently undoing a business process adaptation in event-driven environments, considering also the correlated adaptations that happened afterwards.  ...  Straight forward approaches for unadaptation can easily end up with corrupted processes, bringing uncertainty to the whole business logic.  ...  We consider here an event-driven adaptation engine based on state-of-the-art mechanisms [8] , represented in FIG. 6.  ...
