Congratulations to David Levy, winner of the Loebner Prize 2009 for “most human computer”. The contest was held September 6, 2009 in Brighton, UK.
This year the contest drew only three finalists. In addition to Mr. Levy’s program, the competitors included previous (two-time) Loebner winner Rollo Carpenter and newcomer Mohan Embar.
As has been the case in previous years, no program fooled the judges by passing as a human. Instead, a bronze medal and cash prize are awarded to the program that comes closest to chatting like a human. The programs were instead scored based on rank. The results were as follows
First Place David Levy - Rank 4.5
Second Place Rollo Carpenter - Rank 5.0
Third Place Mohan Embar - Rank 5.5
As you can see, the scores were very close.
David Levy is an international chess master, whose program Converse previously won the Loebner prize in 1997. He becomes the third two-time Loebner prize winner. Joseph Weintraub’s PC Therapist won the bronze medal four times, and A.L.I.C.E. won three times.
Brian Christian was awarded as the most human human: the confederate who simply behaved as human as possible (without trying to simulate a computer to confuse the judges).
