After analysing the ontology, the entities are either
sorted or unsorted. The entities can be ordered
according to considered importance (centrality)
w.r.t. the ontology or unordered (random). It is
assumed that an ordered list can positively improve
the selection of the most relevant candidate
clusters (in Step 7). However, the question is, does
an ordered list of entities improve the identification
of relevant candidate clusters versus and unordered
list?
