RDF event stream processing based on the publish-subscribe pattern

Abstract

In recent years, RDF event streams have been an increasingly widespread data source in a wide range of domains. Existing systems allow us to automatically record pieces of information concerning everyday fast-paced life. This paper proposes methods of representing and processing RDF streams consisting of RDF graphs with time-varying data annotated by an interval.We introduce a graph-based stream model and a solution for RDF streams processing based on the publishsubscribe interaction scheme. The initial evaluation on our implementation shows that it has great potential.
