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 rdfs ontology lubmsp_onto.nt instances LUBM_500_sp.nt query queries/lubm_query1.sparql
