Lost in Semantics? Ballooning the Web of Data

Abstract

Although Linked Open Data has increased enormously in volume over recent years, there is still no single point of access for querying the over 200 SPARQL repositories. The Balloon project aims to create a Meta Web of Data focusing on structural information by crawling co-reference relationships in all registered and reachable Linked Data SPARQL endpoints. The current Linked Open Data cloud, although huge in size, offers poor service quality and is inadequately maintained, thus complicating access via SPARQL endpoints. This issue needs to be resolved before the Linked Open Data cloud can achieve its full potential.
