Benchmarking Faceted Browsing Capabilities of Triplestores.

The increasing availability of large amounts of linked data creates a need for software that allows for its efficient exploration. Systems enabling faceted browsing constitute a user-friendly solution that need to combine suitable choices for front and back end. Since a generic solution must be adjustable with respect to the dataset, the underlying ontology and the knowledge graph characteristics raise several challenges and heavily influence the browsing experience. As a consequence, an understanding of these challenges becomes an important matter of study. We present a benchmark on faceted browsing of triple stores, which allows systems to test their performance on specific choke points on the back end. Further, we address additional issues in faceted browsing that may be caused by problematic modelling choices within the underlying ontology.
