The knowledge base of an expert system includes both facts and heuristics.
Every expert system consists of two principal parts: the knowledge base; and the reasoning, or inference, engine. The knowledge base of expert systems contains both factual and heuristic knowledge.
A knowledge-based system is a computer program that reasons and uses a knowledge base to solve complex problems. A more specific definition of the domain restricts it to expert systems.
In artificial intelligence, an expert system is a computer system that emulates the decision-making ability of a human expert. Expert systems are designed to solve complex problems by reasoning through bodies of knowledge, represented mainly as if–then rules rather than through conventional procedural code.
