| Research Type | Experimental | To test the practical applicability of LMG, we have conducted a set of experiments on query answering using both LMG, and NAIVE. In particular, we compared the evaluation time of 8 queries, over an ontology containing about 100000 ABox axioms, and 260 TBox axioms. The tests have been performed using Mastro [Calvanese et al., 2011] as OWL 2 QL reasoner with java 7 on a Dell computer equipped with an Intel i7 2.70GHz processor, assigning 2GB memory to Java. The results of the experiments, reported in Table 1, show that, except for query Q1(x, y)... LMG outperforms NAIVE in terms of evaluation time, thanks to the smarter instantiation of the metavariables performed by LMG. |
