Abstract
The LOD cloud is gathering a lot of momentum, with the number of contributors growing manifold. Many prominent data providers have submitted and linked their data to other dataset with the help of manual mappings. The potential of the LOD cloud is enormous ranging from challenging AI issues such as open domain question answering to automated knowledge discovery. We believe that there is not enough technology support available to effectively query the LOD cloud. To this effect, we present a system called Linked Open Data SPARQL Querying System (LOQUS), which automatically maps users queries written in terms of a conceptual upper ontology to different datasets, creates a query plan, sends sub-queries to the different datasets, merges the results and presents them to the user. We present a qualitative evaluation of the system based on real-world queries posed by other researchers and practitioners.
