MYCIN, an early expert system developed at Stanford University in 1972, aimed to assist physicians in diagnosing and treating bacterial infections. Utilizing a knowledge base of over 600 rules about infectious diseases and a backward chaining inference engine, MYCIN diagnosed infections and recommended antibiotics. A breakthrough in artificial intelligence, MYCIN significantly influenced the development of expert systems. It was among the pioneering medical AI systems evaluated in a clinical setting. In a Stanford University Medical Center study, MYCIN achieved a 95% accuracy rate in diagnosing and recommending antibiotics for bacterial…
