Loebner Prize Contest 2003 'Can machines think?' - Alan Turing, 1950

The Contest

Background

The Loebner Prize Contest in Artificial Intelligence was established in 1990 by Hugh Loebner and was first held at the Boston Computer Museum in 1991. The Loebner Prize Medal and cash award is awarded annually to the designer of the computer system that best succeeds in passing a variant of the Turing Test. In accordance with the requirements of the Donor (as published in the June 1994 Communications of the ACM) the winner of the $100,000 Gold Prize must be prepared to deal with audio visual input, and appropriate competitions will be held once Competitors have reached Turing's 50:50 likelihood level of being mistaken for a human. An intermediate Silver Prize of $25,000 will be offered for reaching this level in a text-only test. There is also an Annual Bronze Prize, currently $2,000, which is awarded to the designer of the "most human computer" as rated by a panel of judges.

2003 Finalists and Reservists

The original finalists were, in alphabetical order:

Three reservists were also selected:

In the event, one of the finalists was eliminated and replaced by Peter Neuendorffer's Gabber.

Our commiserations to the other entrants who did not qualify for the finals. We received over 20 entries, and the standard was very good, but unfortunately we could only accommodate eight entries (plus two human confederates) in the finals so it was inevitable that many entrants would be disappointed. We hope that they will try again next year.

The entries were judged by eight preliminary round judges, with each entry being assessed by at least three judges in accordance with the Official Rules. The judges ranged from students to retired people and included both men and women, located in the USA and the UK. The Chief Judge was Professor Nigel Gilbert, Pro-Vice-Chancellor of the University of Surrey.

The final results are now available, together with photographs and dowloadable transcripts of the judges' conversations.
