I remember Freebase, I even recall fact-checking on it a while ago.. I'd be interested to see how their current efforts are shaping up - if it's all ML or requires human assistance.
They use WikiData now to fulfil the same basic function as Freebase, so it does seem that they require some human assistance. Don't know if they've ported everything over from Freebase yet, will have to check up on that.
