Loebner prize
[Could someone write a comprehensible introduction, perhaps beginning with "The Loebner Prize is ... ", instead of acting as if the reader already knows that?]
Dr. Hugh Loebner is the one that established the prize in conjuction with The Cambridge Center for Behavioral Studies. Please access the prize site at http://www.loebner.net/Prizef/loebner-prize.html which will provide more detailed information about the prize and past winners.
