Hello Mark, There are no good methods for these two questions ATM. I'm extending the inference soon (to get the whole nonrecursive part of OWL) and will try to make something, but I have no solution right now.
More probably, the query would be able to return "explanation hints" for results, like "this resultset row is composed because property P is an inverse functional property (see file XXXX.owl , line NNN), and P has same value O for both original S1 and dupe S2", but it will still be an application-side problem to find a "canonical representatives" for a set of subjects and list of S1-S2 pairs.
