rule-based systems

Rule-based systems are a type of artificial intelligence that use a set of predefined rules to make decisions or solve problems. These rules are often expressed in "if-then" statements. For example, a rule might state, "If it is raining, then take an umbrella." The system processes information and applies these rules to achieve a specific goal, such as answering questions or diagnosing issues. This approach allows for consistent and logical reasoning based on the rules provided, making it useful in areas like expert systems, customer support, and automated decision-making.
