Moreover, some knowledge-based systems have learning capabilities. Expert system (ES) indicates the knowledge-based system that provides for solving problems in a particular domain or application area by drawing inferences from a knowledge base developed from human(73). Some expert systems are able to(74)their knowledge base and develop new inference rules based on their experience with previous problems. The term "expert system" is sometimes used(75)with "knowledge-based system", but should be taken to emphasize expert knowledge.
