Query: Querying Linked Data: An Experimental Evaluation of State-of-the-Art
  Interfaces   The adoption of Semantic Web technologies, and in particular the Open Data
initiative, has contributed to the steady growth of the number of datasets and
triples accessible on the Web. Most commonly, queries over RDF data are
evaluated over SPARQL endpoints. Recently, however, alternatives such as TPF
have been proposed with the goal of shifting query processing load from the
server running the SPARQL endpoint towards the client that issued the query.
Although these interfaces have been evaluated against standard benchmarks and
testbeds that showed their benefits over previous work in general, a
fine-granular evaluation of what types of queries exploit the strengths of the
different available interfaces has never been done. In this paper, we present
the results of our in-depth evaluation of existing RDF interfaces. In addition,
we also examine the influence of the backend on the performance of these
interfaces. Using representative and diverse query loads based on the query log
of a public SPARQL endpoint, we stress test the different interfaces and
backends and identify their strengths and weaknesses.
