—In the era of big data processing there is an emerging need for methodologies supporting the management of data-intensive application scenarios. Complex Event Processing is an integral part of many fast data application as an underlying technology for event correlation and pattern detection. Increased volume of event streams as well as the demand for more(More)
We present StreamPipes, a semantics-based approach aiming to provide a description and management layer to define and execute stream processing pipelines consisting of multiple, potentially heterogeneous runtime implementations. StreamPipes consists of i) an ontology-based model to describe requirements and capabilities of stream processing services, (ii) a(More)
In this demo, we present the final version of the ALERT system. ALERT aims to improve the collaboration and coordination of developers in open source software development. In this sense, ALERT provides active support for developers in form of real-time notifications. The system is based on an event-driven architecture which integrates data from several(More)
In this demonstration, we present a system for real-time monitoring of personal fitness performance indicators. The system uses smartphone and wearable sensors for gathering information (measurements) from the user in order to enable improving the fitness activity. The main advantages are 1) dynamic fitness monitoring, which enables adapting on-the-fly the(More)
Modern organizations need real-time awareness about the current business conditions and the various events that occur from multiple and heterogeneous environments and influence their business operations. Moreover, based on real-time awareness they need a mechanism that allows them to respond quickly to the changing business conditions, in order to either(More)
In this paper we present the ALERT system that improves free/libre open source software (FLOSS) coordination by maintaining awareness of community activities through real-time, personalized, context-aware notification. The ALERT system is an active collaboration platform, i. e. a virtual actor that interacts with the developers, processes and recognizes(More)
