How Facebook Built Natural Language Into Graph Search
Nerval's Lobster writes "Facebook's Graph Search is an ambitious project: give users the ability to search through the social network's vast webs of data via natural-language queries. But that's much easier said—so to speak—than done. Although human beings think nothing of speaking in 'natural' language, a machine must not only learn all the grammatical building-blocks we take for granted—it needs to compensate for the quirks and errors that inevitably pop up in the course of speech. The Facebook team tasked with building Graph Search also knew that the alternate option, keyword-based search, wasn't a viable one. 'Keywords, which usually consist of nouns or proper nouns, can be nebulous in their intent,' Facebook engineering manager Xiao Li wrote in an April 29 posting on Facebook's blog. 'For example, "friends Facebook" can mean "friends on Facebook," "friends who work at Facebook Inc," or "friends who like Facebook the page."' That left the team with building a natural-language interface. The posting digs deep into the elements of the backend, including everything from 'parse trees' to a lexical analysis system."
Well I haven't seen it rolled out to anyone yet so they're holding back the ads. Vapourware as far as I care.
Not seen the new news feed either.
Civilization is an ongoing collective effort. Why do we whine about this? Next time you or a loved one who desperately needs the same bright minds to come up with remedy or a cure to a devastating disease, tell me why you don't whine.
