Abstract

The cloud of Linked Open Data is steadily growing, yet it remains largely
inaccessible to the general public, due to the technical barrier posed by
the requirement to know a formal query language such as SPARQL. In
this article, we present a new approach for visual query formulation toward
arbitrary SPARQL endpoints, and we show a working prototype developed
to improve the accessibility to Linked Open Data sources for non-computer
experts. We show how the prototype can be employed to simplify access to
governmental Linked Open Data with a case study from the Norwegian Entity
Registry.
