Hi Aaron! Would be great to work with someone from Cray but I don't have a good idea how to use ML here, nor indeed a lot of trust in using ML to produce or fix mappings. E.g. see this exchange: https://twitter.com/valexiev1/status/565814870973890560 Generating 30% wrong prop maps for the Ukrainian dbpedia is IMHO doing them a disservice! Who's gonna clean up all this? I guess I'm more of a MLab (Manual Labor) guy, I just learned they coined such alias for crowdsourcing: http://link.springer.com/chapter/10.1007%2F978-3-319-13704-9_14 > > DBO: dbo:parent rdfs:range dbo:Person > > Wikipedia: | mother = [[Queen Victoria]] of [[England]] > For your example of the dichotomy with the domain and range of "mother" and > queen Victoria being the "mother", this begs for contextual approach to that > concept.... She IS the mother, not sure what you mean. Here a simple post-extraction cleanup can take care of it: remove all statements that violate range (so dbo:parent [[England]] will be removed). But we dare not do it, because many of the ranges are imprecise, or set wishfully without regard to existing data / mappings. (As usual, the real data is more complex than any model of it.) So we need to check our Ontological Assumptions and precise domains/ranges before such cleanup.
