Generating Linked Data in Real-time from Sensor Data Streams

Abstract

In this Chapter, we focus on dealing with data originating from sensor data streams, in order to materialize an intelligent, semantically-enabled data layer. First, we introduce the concepts that are covered in this Section: real-time, context-awareness, windowing, information fusion. Next, we mention the difficulties associated with the attempt of creating a semantic sensor network, we note our architectural concerns by presenting a number of issues that have to be dealt with when designing a system for the real-time information integration from distributed data sources and sensors. Finally, the anatomy of a system for the end-to-end data multi-sensor data fusion and semantic enrichment is illustrated, while the end-to-end information flow and respective steps are analyzed.
