“…In this section, we present an evaluation of SQG with respect to a number of metrics. Since one of our objectives was to show that SQG can be used on different ontologies, we reused the same set of ontologies for evaluating RODG [9], i.e., the SDR ontology [32] developed by us, and five existing ontologies in different domains: the eDIANA ontology [12], the IoT ontology [19,21], the Smart Appliances REFerence (SAREF) ontology [10,36], the Univ-Bench ontology [41] and the WM30 ontology [39]. Table 2 summarizes the basic characteristics of each ontology, including the number of classes, object properties, data properties, class axioms, object property axioms and data property axioms.…”
