Deep Dive
An Expert System is a computer program designed to emulate the decision-making ability and behavior of a human expert in a specific domain. These systems typically consist of two main components: a knowledge base, which stores domain-specific facts, rules, and heuristics gathered from human experts; and an inference engine, which applies logical rules to the knowledge base to derive conclusions and offer recommendations. Unlike conventional programs that follow procedural steps, expert systems leverage symbolic reasoning and explicit knowledge representation to solve complex problems that typically require human expertise.
