No AI system won the Loebner Prize this year but the chatbot Rosette did take home the bronze medal.
The Loebner Competition functions much like the Turing Test. Judges hold blind conversations with either a computer or a human. To win a computer must fool a judge into thinking that it is human. This hasn't happened yet, though a number of AI systems have scored rather high.
In 2008 NKU computer science alum Fred Roberts and his team at Artificial Solutions earned a bronze metal with Elbot, a chatbot.
