'''CADUCEUS''' was a medical [[expert system]] finished in the mid-1980s (first begun in the 1970s- it took a long time to build the [[knowledge base]]) by [[Harry Pople]] (of the University of Pittsburgh), building on Pople's years of interviews with Dr. [[Jack Meyers]], one of the top [[internal medicine]] diagnosticians and a professor at the [[University of Pittsburgh]]. Their motivation was an intent to improve on [[Mycin|MYCIN]] - which focused on [[blood]]-borne infectious [[bacteria]] - to focus on more comprehensive issues than a narrow field like [[Bacteremia|blood poisoning]] (though it would do it in a similar manner); instead embracing all internal medicine. CADUCEUS eventually could diagnose ~1000 diseases.
While CADUCEUS worked using an [[inference engine]] similar to MYCIN's, it made a number of changes (like incorporating [[abductive reasoning]]) to deal with the additional complexity of internal disease- there can be a number of simultaneous diseases, and data is generally flawed and scarce.
