Entries closed Sunday, March 15 for the annual Chatterbox Challenge 2009 (CBC). Judges have until April 30, 2009 to conduct performance tests on 20 chatbots.

Sponsored by InfraDrive, the CBC is an online contest that allows chatbot developers to participate and evaluate the intelligence of their bots in a variety of ways, including Turing tests.

This year’s entries include A.L.I.C.E. by Dr Richard S. Wallace, Brother Jerome by Peter Cole and Fizzy Schiznoid by Jeremiah R. McCarroll.

The contest was founded by Wendell Cowart in 2001.
