Re: [Wikidata] Freebase Sets (based on Google Sets)

So the Venn diagramming artwork that Freebase Sets logo used is appropriate. To explain it for you in Wikidata terms... As a user, Freebase Sets could be used to input let's say 2 items (max of 5). It would run queries to figure out for the user what other topics had the same overlapping statement values (Venn union). Figure out whats common, give me other things that share that commonality. Ex. I enter the following items using Wikidata as example, and on each selecting the Q id (just as Wikidata Search dropdown suggests, it worked the same way) "Eiffel Tower" "Bavarian Forest National Park" I then click on "Find Set" and it would run queries on those 2 items to find other items that shared similar statements AND their concrete values matching exactly for all those statements (as best it could with a few simple algorithms, hints, exclusions) Statements and Concrete values common to those 2 items (those in () parentheses might be excluded as not useful) : instance of inception named after country located in the administrative territorial entity topic's main category (official website) (image) Incidentally, the above 2 items would result in probably 0 results since their values don't match on any of those statements. But it was just a quick example to show you how you could put in very disconnected items COULD be put into a query to find SOME overlapping relationships discovered. That was the power of Freebase Sets. It offered a different way to explore the graph of relations. In Wikidata terms, imagine being able to hold down CTRL and being able to interactively "queue up" clicking all the ellipses (triple dot next) on ALL the same statements between the 2 items, that finally runs a big combined query to find all the matching items that share that "overlapping statement set". (Venn union) But it could do this with more than just 2 items to give you some really cool and interesting result overlaps you normally would not discover or know about! Technically, it's actually not that hard to put a Lab tool together that would be able to mimic Freebase Sets. Some of our existing Example Queries in WQS are basically manually curated Freebase Sets. But a tool could automate the discovery of overlapping statements between X items.
