Hello All,
It struck me that one interesting way to see if subclasses are useful was to test this hypothesis.
Let QID_a and QID_b be two Wikidata items.
Conjecture: if QID_b is subclass of QID_a, then count_stelinks(QID_b) <= count_sitelinks(QID_a).
Has anyone investigated this problem, or can think of an efficient way to test it? Or can tell me why it ought not to be true?
