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:

- Interference engine -- This component uses the facts and rules in the knowledge base to find and learn new knowledge or patterns.
