What is ELIZA?
ELIZA was an early computer program that “chatted” with the user. It served as a parody of a Rogerian psychoanalyst. By incorporating parts of the user’s statements in the responses, it could be seen (with a lot of imagination) as conversing with the user. It has since been implemented on nearly every computer platform in existence. ELIZA mode in chatbot is one imlementation of what was perhaps the first chatbot. For more information, see Joseph Wizenbaum’s ELIZA: Communcations of the ACM, January 1966.
