I was just googling and came across something I’ve never seen before. The first result for “bill gates children” was “Bill Gates — Children: 3” with an attribution to wikipedia.
I couldn’t repeat the result searching for the children of other public figures, but then I tried “Bill Gates born”, and got another semantic result from Wikipedia:
The born search works for lots of public figures, like Elvis and Nixon.
This really surprised me, especially since I haven’t seen anyone else talking about it. I wonder if this is a response to microsoft’s recent acquistion of Powerset and an answer to those wondering whether the Microsoft/Powerset combo would beat Google.
Searching Powerset for “Bill Gates Born” delivers a similar looking result as the top item. (Update: I just noticed that Powerset’s summary result is actually from Freebase. Dumb that I didn’t notice, because my first thought was that that was where Google was pulling their info from.
The feature is rather old. Basically every Wikipedia information that is stored in a template information can be queried that way:
The template reads:
