Abstract : An expert system is a computer program that provides expert level solutions to important problems. Some essential features required of such an expert system are seen to be the following: (1) It has the ability to reason and to make inferences under new situations; (2) It can use judgmental as well as formal knowledge; (3) It provides explanations of its reasoning process and answers questions about its knowledge; and (4) It has the ability to easily and modularly add new knowledge. It should be noted that the first characteristic is what substantially differentiates an expert system from an information system. The structure of an expert system can be seen to consists of the following items: (1) A set of rules. (2) A set of data. (3) An inference mechanism.
