The knowledge base is typically created by interviewing human experts and by extracting information from documents and databases.<\/p>\n<p>The inference engine is the second most important component of an expert system.

The inference engine typically uses a rule-based reasoning approach.<\/p>\n<p>The user interface is the third most important component of an expert system. It allows the user to interact with the expert system.
