Abstract :
In this paper we consider the problem of generating parameters for queries in RDF benchmarks. We show that uniform random sampling of the substitution parameters is not well suited for RDF benchmarks, since it results in unpredictable runtime behavior of queries. We formulate a formal problem of parameter generation to ensure stable and statistically significant benchmark results.
