Knowledge-based systems and especially expert systems are a remarkable class of artificial intelligence applications. A knowledge-based program is characterized by a clear separation between the knowledge it contains (the so-called knowledge base) and the inference mechanisms which are used for knowledge processing. This dichotomy largely contributes to the maintenance and evolution of the programs, two aspects which are essential for artificial intelligence systems.
