Expert System

An expert system is typically designed to provide capabilities similar to those of a human expert when performing a task. Moreover, it can be used to drive vehicles, provide financial forecasts or do things that human experts do.

An expert system usually has two core components:

• Knowledge base -- This component consists of data, facts and rules for a certain topic, industry or skill, usually equivalent to that of a human expert.
• Interference engine -- This component uses the facts and rules in the knowledge base to find and learn new knowledge or patterns.
