Here we explain the step-by-step to generate the LUBM-SP datasets, and run the query evaluation

Generate LUBM-SP

1. cd lubmsp
2. Run the code, the number of university may be 50, 500, or 1000
java -jar lubmsp_1.0.0.jar -univ 500 -index 0 -onto http://knoesis.org/lubmsp
3. Check for three data files generated
LUBM_500.nt: the original LUBM in the form of ntriples
LUBM_500_sp.nt: the LUBM-SP in the form of ntriples
LUBM_500.rdf: the original LUBM in the form of RDF/XML

Query evaluation in Jena

1. cd lubmsp
2. java -jar lubmsp_query_eval_1.0.0.jar 
or
rlwrap java -jar lubmsp_query_eval_1.0.0.jar
reasoner:
