Richard Wallace’s Alice chatbot program beat three other finalists to take the 2004 bronze metal for the Loebner Prize competition.

The bronze metal goes to the program best able to maintain a life-like conversation. No program has won gold or silver metals, which will go to programs able to convince half the judges that the program is a human, either via video (gold) or text (silver).

The Alice program also won in 2000 and 2001.
