CADUCEUS (expert system)


CADUCEUS was a medical expert system finished in the mid-1980s by Harry Pople, 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 - which focused on blood-borne infectious bacteria - to focus on more comprehensive issues than a narrow field like blood poisoning ; instead embracing all internal medicine. CADUCEUS eventually could diagnose up to 1000 different diseases.
While CADUCEUS worked using an inference engine similar to MYCIN's, it made a number of changes to deal with the additional complexity of internal disease- there can be a number of simultaneous diseases, and data is generally flawed and scarce.
CADUCEUS has been described as the "most knowledge-intensive expert system in existence".
