A user-friendly expert system with new types of knowledge bases is disclosed. The major new components in the invented expert system are: A stored knowledge base in the form of an array, an input knowledge base in the form of a truth table or in some other user-defined forms, a transfer engine being a built-in computer program transferring the input knowledge base to the stored knowledge base, and an automatic inference engine being a built-in computer program reasoning with the stored knowledge base by a double loop. No matter what the size of the input knowledge base is, and no matter what the size of the input knowledge base is, and no matter what kind of knowledge is stored in it, the double loop always processes the inference automatically, and no compilation is necessary. Therefore, the inference engine is called the automatic inference engine and the system is called the automatic expert system.
