Web-oriented Event Processing

چکیده

In this work we present an approach for Web-oriented event processing based on the combination of efficient event processing, expressive Semantic Web technologies and the management thereof. The approach is a distributed semantic system that serves as an Event Marketplace: heterogeneous events from the Web modelled in RDF are matched and integrated using a processing language we designed and describe in this work. The system consists of three main components: an event-driven service bus to connect event sources, a storage layer to maintain historic events and an event processing layer to combine, integrate, filter and derive events. Event-driven applications are implemented on this architecture by expressions in a language supporting hybrid queries mixing real-time (on pushed data) and historic (pull data) queries. A governance component enforces efficient access control on event streams and storage. The main advantages of the system are its Web-orientation by adhering to several open and extensible standards, its pattern language offering the combination of real-time and historical queries on events and its governance capabilities creating a multi-tenant system based on permissions. The system uses Web technologies such as Linked Data, RDF and SPARQL to model, organize, locate, process and control access to events. Termin: Freitag, 25.

Asynchronous Geospatial Processing: An Event-Driven Push-Based Architecture for the OGC Web Processing Service

Geospatial processing tasks like solar potential analyses or floodplain investigations within flood scenarios are often complex and deal with large amounts of data. If such analysis operations are performed in distributed web-based systems, technical capabilities are mostly not sufficient. Major shortcomings comprise the potentially long execution times and the vast amount of messaging overhead...

Towards Event - Driven Context - Aware Web Services 1

Web services provide a successful way to communicate distributed applications, in a platform-independent and loosely coupled manner. Even though there are examples of good practice for the design, development, and management of web services, getting services to be context-aware is still under investigation. Current proposals require communication with an external context server or manager, slow...

A Case Based Tool for Monitoring of Web Services Behaviors

Monitoring systems is of great practical importance. The use of service oriented distributed system is increasing. Within service orientation (SO) web services (WS) are the de facto standard for implementing service-oriented systems. Users want uninterrupted service from service providers. So the management of these systems is becoming crucial. Monitoring is an important part of any management ...

Integration Of Geosensor Data By Means Of An Event Abstraction Layer

With the new generation of Sensor Web Enablement1 (SWE) [2] the number of possibilities to access sensor observations has increased considerably. Nowadays, more and more data providers are making their data sets available in the Web using standard services, e.g. Sensor Observation Service (SOS) [7]. These services are easily integrated in Service Oriented Architectures (SOA), which allow users ...

Event Processing in Web Service Runtime Environments

Following the Service-oriented Architecture (SOA) paradigm shown in Figure 1, service providers register services and corresponding descriptions in registries. Service consumers can then find services in the registry, bind to the services that best fit their needs, and finally execute them. Web services (Weerawarana, Curbera, Leymann, Storey, & Ferguson, 2005) are one widely adopted realization...
