Expert systems are a new class of application programs. They should make the "knowledge" of an expert in a subject area available on a computer, usually as an interactive dialogue system.

The core of an expert system is a Inference machine. It draws conclusions from the knowledge stored there according to a specific strategy and thus develops new knowledge.
