WatDiv

Waterloo SPARQL Diversity Test Suite

WatDiv is a benchmark designed to measure how an RDF data management system performs across a wide spectrum of SPARQL queries with varying structural characteristics and selectivity classes.

WatDiv consists of two components: the data generator and the query (and template) generator. The data generator generates the RDF dataset of a specified size while the query generator focuses on the generation of test queries that will be used in the study.
