Approximate Semantic Event Processing in Real-time Linked Dataspaces

Abstract

Within dataspaces, data sources are not necessarily fully integrated or homogeneous in their schematics and semantics. For dataspaces to support a real-time response to situations of interest when a set of events take place, for example from sensor readings, there is a need for a principled approach to tackling data heterogeneity within real-time data processing. In this chapter, we detail techniques for developing dataspace support services for dealing with the semantic heterogeneity of real-time data.
