DefinitionA rule-based (ルールベース) system makes decisions by applying facts to "if ... then ..." rules that people have written in advance.
ExplanationEach rule is a pair of IF (a condition) and THEN (a conclusion or action), and a system that turns an expert's knowledge into a set of rules so it can make judgments in the expert's place is called an expert system. It can easily show which rule served as the grounds for a decision, but writing and maintaining the rules takes effort, and it cannot handle situations its rules do not cover.
AnalogyIt is like using the troubleshooting table in an appliance manual, such as "if the lamp is blinking, clean the filter," to pick a fix from the symptom.
