A knowledge-based system (KBS) is a form of artificial intelligence (AI) that uses a knowledge base to solve complex problems. It’s designed to capture the knowledge of human experts to support decision-making. The system is composed of two main components: a knowledge base and an inference engine.
A KBS can be used in medical diagnosis, where it can analyze patient symptoms and medical history to make a diagnosis. For example, a doctor can input patient data into the system, and the KBS will use its knowledge base to identify potential diagnoses based on the inputted data.
