CARL (Chatbot with Automatic and Rapid Learning) is a computer program that learns by talking to people. It memorizes the phrases that you say to it, and the links between what CARL said and what you said. Over time, it has a more and more complete vocabulary, which creates the illusion that it knows what it's talking about. But most of the time it just says random stuff to get more knowledge about phrases that have fewer links.
