The first step includes loading an ontology and
analysing it to find the relationships among the
entities. The ontologies are expressed in OWL
(W3C, 2004). When loading an ontology, typically
only some of the relationships are found. However,
a semantic reasoner can be utilised, like the Pellet
OWL Reasoner (Sirin et al., 2007), to extract all
the relationships among the entities. Though, the
question is, does this extra knowledge provided by
a reasoner increase the quality of the FVs?
