An expert system is an example of a knowledge-based system. Expert systems were the first commercial systems to use a knowledge-based architecture. A knowledge-based system is essentially composed of two sub-systems: the knowledge base and the inference engine. The knowledge base represents facts about the world.
Expert system, a computer program that uses artificial-intelligence methods to solve problems within a specialized domain that ordinarily requires human expertise. The first expert system was developed in 1965 by Edward Feigenbaum and Joshua Lederberg of Stanford University in California, U.S. Dendral, as their expert system was later known, was designed to analyze chemical compounds.

This distinction between expert knowledge and the problem-solving method, possible in many domains, is a characteristic feature of the architecture of expert systems. The only difference between expert systems and knowledge-based systems is that the former derive their knowledge from experts (Fig. 1.1).
AI memories — expert systems. This is part of a four post series spanning two blogs. One post gives a general historical overview of the artificial intelligence business.; One post (this one) specifically covers the history of 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 about knowledge, like an expert, and not by following the procedure of a developer as is the case in conventional programming.

Another example from computer science is that an expert system may be taught by a human and thereafter considered an expert, often outperforming human beings at particular tasks. ... In earlier periods of history, simply being able to read made one part of an intellectual elite.
4. Expert System Architecture. An expert system is, typically, composed of two major components, the Knowledge-base and the Expert System Shell. The Knowledge-base is a collection of rules encoded as metadata in a file system, or more often in a relational database. The Expert System Shell is a problem-independent component housing facilities ...
