Expert systems & the human/computer interface: abstract computer graphics illustration of an expert system. Two human heads face each other; between them is positioned a personal computer (PC), with a knowing human eye displayed on its monitor. An expert system performs the decision- making processes of a human specialist. An integral part of such a system is its knowledge base, a rigorous distillation of the specialist's knowledge & experience.

In addition, an inference program must marry facts obtained from the user with rules in the knowledge base.
