Expert System

A form of AI that attempts to replicate a human's expertise in an area, such as medical diagnosis. It combines a knowledge base with a set of hand-coded rules for applying that knowledge. Machine-learning techniques are increasingly replacing hand coding.

Computer system that provides for expertly solving problems in a given field or application area by drawing inferences from a knowledge base developed from human expertise.

A computer system emulating the decision-making ability of a human expert through the use of reasoning, leveraging an encoding of domain-specific knowledge most commonly represented by sets of if-then rules rather than procedural code. The term “expert system” was used largely during the 1970s and ’80s amidst great enthusiasm about the power and promise of rule-based systems that relied on a “knowledge base” of domain-specific rules and rule-chaining procedures that map observations to conclusions or recommendations.

An expert system is an intelligent computer program that uses knowledge and inference procedures to solve problems that are difficult enough to require significant human expertise for their solution.
