The wealth of information in the linked open data cloud (hereafter LOD) is large and growing, enabling comparisons between previously isolated datasets to be made. However, exploring the linked data cloud is difficult for users unfamiliar with semantic web concepts such as SPARQL and RDF (Resource Description Framework). In this paper, the authors discuss the development of openChart, a quantitative linked open data charting tool. It targets novice semantic web users by generating SPARQL queries to present interesting information. They also acknowledge the problems encountered in development and suggest improvements.
