Figure 2 shows the type of modification required for worthy items for both ontologies, showing that the majority of MCQ items required none or only minor modification: 26 out of 36 items for HistOnt and 27 out of 49 items for SemQ. The MCQ items generated from SemQ required more major and minor modifications than those from HistOnto.
For SemQ, 72 rule violations were found compared with 74 for HistOnto.
Although the maj ority of items generated from SemQ were considered to be educationally significant by the evaluators, for the HistOnto ontology, almost half of the items generated were believed to be irrelevant.
The OntoQue system was chosen as the platform for the experiments with two domain ontologies, SemQ (Arabic vocabulary ontology) and HistOnto (history ontology).
