Chatterbox challenge

The Chatterbox challenge was an annual challenge that began in 2001. It was designed to test a chatterbot's ability to simulate a real person in a conversation. Each chatterbot was judged based on how well it responds to several questions and the overall conversation.

Unfortunately, in late 2015 the Chatterbox challenge website went offline but is found on the Internet archive with all previous conversations.
