Your Questions WereRequested Session Focus My internal contacts here at Nuance have requested a basic introduction on semantic web, with the discussion biased toward two use cases: Question answering by machine “ When does home depot close?” “ Who has tylenol on sale?” “ Where is the nearest shoe store that carries Rockport?” (See Semantic Search) Automated agents “ Buy two tickets to the Patriots Jets game.” “ Reorder Bond Street English Breakfast from Upton Tea.” “ Find the lowest price on a Canon 70 to 200 f4 IS lens and email me the link.” (Discuss Siri)
