MYCIN was an early expert system created to help medical doctors in the diagnosis of various infections. It was designed in the 1970s by researchers at Stanford University, who hoped to create one of the first practical knowledge bases. It diagnosed roughly 69% of cases correctly through a list of questions and a KB of about 600 rules. Although MYCIN had similar diagonis rates to that of a doctor, it was never used in practice, as it brought about moral, legal, and fesability issues.
