Its a good talk, though maybe should be called "theorizing from massive amounts of data". Makes you wonder what Google are keeping under wraps for now, and how the powerset approach can compete, except maybe for domain-specific stuff.
well, they do statistical learning of inflections and closely related terms.
google "knows" (believes with high probability, I guess) that PWC is an abbreviation of PriceWaterhouseCoopers, for instance.
you can see this directly in how google highlights terms in search results. you can certainly find instances where they "should" have gotten something but didn't, or made a mistake, but it works well enough most of the time.
