Cleverbot

Cleverbot is a web application that uses an artificial intelligence algorithm to converse with humans. It was created by the Turkish AI scientist Rollo Carpenter, who also created Jabberwacky, a similar web application. It is unique in the sense that it learns from humans, remembering words within its AI. In its first decade Cleverbot held several thousand conversations with Carpenter and his associates. Since launching on the web in 1997, the number of conversations has exceeded 65 million.

How It Works

Unlike other chatterbots, Cleverbot's responses are not programmed. Instead, it "learns" from human input; Humans type into the box below the Cleverbot logo and the system finds all keywords or an exact phrase matching the input. After searching through its saved conversations, it responds to the input by finding how a human responded to that input when it was asked, in part or in full, by Cleverbot.^[3][4] Although the commercial version of Cleverbot supports more than one thousand requests per server, the web-hosted service handled 1 or 2 people per server. This allowed more speed and quality of responses hosted by the artificial intelligence system.

Cleverbot participated in a formal, Turing Test at the 2011 Techniche festival at the Indian Institute of Technology Guwahati on September 3, 2011. Out of the 334 votes cast, Cleverbot was judged to be 59.3% human, compared to the rating of 63.3% human achieved by human participants. A score of 50.05% or higher is often considered to be a passing grade.^[5]
