JPoT: Just another Populator of TBoxes

The OWL2’s populators are currently an important support to empirically evaluate the reasoners and/or to escort the practitioners by leveraging instantiations in their knowledge bases. In this paper, after having evoked the closest approach describing their strengths and weakness, we present Just another Populator of TBOX (JPoT). This purely syntactic and domain independent populator is based on a random process of concept, role and data instantiations guaranteeing consistency of knowledge bases founded on TBOXes expressed in ALCQ(D). Moreover, we demonstrate that data instantiations can be tricky when the expectation of the modeler is to obtain a sound knowledge base able to pass the equivalent of a Turing test. Finally, we evaluate the performances of JPoT.
