MYCIN

MYCIN was an early expert system developed in the 1970s to assist doctors in diagnosing bacterial infections and recommending appropriate antibiotics. It used a knowledge base of medical rules and an inference engine to analyze patient data, such as symptoms and test results. MYCIN could suggest potential diagnoses and treatment options with reasonable accuracy, serving as a decision-support tool. It was notable for demonstrating how computers could emulate expert reasoning in specialized fields. While not used in everyday practice today, MYCIN paved the way for modern clinical decision support systems and advances in artificial intelligence in medicine.
