OK here's my take on the second presentation here (responding to this mail because it has the link to the presentation). At first I was surprised by the huge gap between the number of founders on enwiki (44,000) and only 2,000 on Wikidata, but then I recalled that many COI entries on living people eventually get merged into their companies. Though founder-company relationships are interesting, I prefer looking at the work on the family relationships, which is something I have worked on quite a bit for 17th-century biographies. It's a real pain to update these in Wikidata and so it would be great to get the edits these guys prepared loaded into some Wikigame. I also really liked their "factor graph model" and we could use something like this as a set up for Wikigames involving not just family relationships, but also employer-employee, prize lists-prize recipient, alumni lists, lists of mayors, abbots and pretty much anything that could add quality info to person items. I think it would be really useful to followup this work with looking into ways to get their prepared edits actually into Wikidata (with the Wikipedia reference statements) but also ways to expand their model.
One problem we have with Wikidata are inverse properties, so e.g. famous victims and their killers. We have a killed property but no killed by property and so on. It would be nice to implement an easy factor graph model for such properties so that inverse properties become unecessary.
