Athough I’ve explored Freebase in several ways, I hadn’t seen the way it is now integrated — along with Wikipedia — into the Powerset demo of natural language search. It’s quite eye-opening to see the answer to a deceptively simple query like Tim O’Reilly’s siblings.

Assuming that a database goes to the trouble of actually knowing Tim as an entity, knowing his siblings as entities, and knowing their relationships, it’s fascinating to think about when you’d want to do Parallax-style exploration — in this case, find Tim, then click to see his siblings — and when you’d want to cut to the chase by asking a direct question. Personally I’d want both modes available, but I suppose some people will mainly prefer to navigate and others to ask questions.
