Loebner Prize 2014

Loebner Prize 2014 @ Bletchley Park


The Loebner Prize is the oldest Turing Test contest, started in 1991 by Hugh Loebner and the Cambridge Centre for Behavioural studies. Since then, a number of institutions across the globe have hosted the competition including recently, the Universities of Reading, Exeter and Ulster. In 2014, the contest will be run under the aegis of the AISB, the world’s first AI society (founded 1964) at Bletchley Park where Alan Turing worked as a code-breaker during World War 2.

The Contest

The 2014 contest will run in a similar way to those in previous years. The contest consists of 4 rounds where in each round, the 4 judges will each interact with two entities using a computer terminal. One of these entities will be a human ‘confederate’ and the other an AI system. After 25 minutes of questioning the judge must decide entity is the human and which is the AI. If a system can fool half the judges that it is human under these conditions, a Silver Medal and $25,000 will be awarded to the creator of that AI system. In the event that this doesn't happen, prizes will be awarded to the creators of the AI system as follows in accordance with judges’ ranked scores:

1st place - a bronze medal and $4000
2nd place - $1500
3rd place - $1000
4th place - $500

The top four entries from the pool of entries that conform to the entry specifications will be selected as follows. Each entry will be provided with a set of 20 questions in English in a similar format to previous competitions. The responses from each of the AI systems will be recorded for this question set and then assessed for how human their responses are. It is likely, but not guaranteed, that this will be carried out by an audience of staff and students at the University of Exeter. The top 4 entries from this process will be entered into the finals of the competition at Bletchley Park. The contest management’s decision on selection is final.

Contest Finals

The contest finals will take place at Bletchley Park, UK on Saturday 15th November 2014. The contest will consist of 4 rounds of judging as described above. The judges and confederates will use standard PCs and each AI will be run on a standard Windows PC, although entrants may provide their own hardware for their AI to run on with prior consultation with the contest management.

Entrants and interested spectators are invited to attend the event, along with interested members of the print, radio, TV and film media.

Further details regarding attendance at the finals day will be posted here in due course.
