In computer science, a rule-based system is a set of “if-then” statements that uses a set of assertions, to which rules on how to act upon those assertions are created. In software development, rule-based systems can be used to create software that will provide an answer to a problem in place of a human expert. These type of system may also be called an expert system. Rule-based systems are also used in AI (artificial intelligence)programming and systems.
