David Levy wins Loebner 2009


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 Loebner winner Rollo Carpenter and newcomer Mohan Embar. (Update: David Levy's program is called Do-Much-More and it is not yet available online).

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.
