EMYCIN

The core inference engine of MYCIN, together with a knowledge engineering interface, was developed under the name EMYCIN, or "Essential MYCIN." It is a domain-independent framework that can be used to build rule-based expert systems for consultation problems such as those encountered in diagnosis or troubleshooting. EMYCIN continues to be a primary example of software that can facilitate building expert systems and has been used in a variety of domains, both medical (e.g., PUFF) and nonmedical (e.g., SACON). The system has been widely distributed in the U.S. and abroad and is the basis for the Texas Instruments software system called Personal Consultant. (1974-1979)
