“…In recognition of this need, the past decade has seen a significant increase in formalisms that integrate uncertainty representation into ontology languages. This has given birth to several new languages such as: PR-OWL (Costa, 2005;Costa, Laskey & Laskey, 2005;Costa, Laskey & Laskey, 2008;Carvalho, 2011;Carvalho, Laskey & Costa, 2013), OntoBayes (Yang & Calmet, 2005), BayesOWL (Ding, Peng & Pan, 2006), P-CLASSIC (Koller, Levy & Pfeffer, 1997) and probabilistic extensions of SHIF (D) and SHOIN(D) (Lukasiewicz, 2008).…”
