TL;DR. AI programs that mimic the decision-making ability of a human expert using a knowledge base and inference rules.
Technical Definition
AI programs that mimic the decision-making ability of a human expert using a knowledge base and inference rules.
How it works
An expert system is an AI program designed to solve complex problems within a specific domain by emulating a human expert's knowledge and reasoning abilities. It typically consists of a knowledge base (containing facts and rules) and an inference engine (which applies rules to derive conclusions). These systems were early successes in AI, particularly in fields like medicine and finance.
