Generating SPARQL query containment benchmarks using the SQCFramework

In this demo paper, we present the interface of the SQCFramework [8], a SPARQL query containment benchmark generation framework. SQCFramework is able to generate customized SPARQL containment benchmarks from real SPARQL query logs. To this end, the framework makes use of different clustering techniques. It is flexible enough to generate benchmarks of varying sizes and complexities according to user-defined criteria on important SPARQL features for query containment benchmarking. We evaluate the usability of the interface by using the standard system usability scale questionnaire. Our overall usability score of 82.33 suggests that the online interface is consistent, easy to use, and the various functions of the system are well integrated.
