ELIZA
ELIZA is a landmark artificial intelligence program developed in 1966 by Joseph Weizenbaum at the Massachusetts Institute of Technology (MIT). It was designed to simulate a conversation by matching user inputs to a set of pre-defined responses, using a simple Pattern recognition technique. ELIZA was named after Eliza Doolittle, a character in George Bernard Shaw's play Pygmalion, who is taught to speak with a proper accent. The program was able to fool some users into believing they were talking to a real person, passing a limited version of the Imitation game test. ELIZA's success can be attributed to its ability to use Context and Communication pathway to generate human-like responses.
