Definition of Expert Systems
Expert systems, also known as knowledge-based systems or intelligent decision support systems, are a type of computer software that utilize artificial intelligence (AI) techniques to emulate the problem-solving abilities of human experts in specific domains. These systems aim to capture and apply expert knowledge in order to provide valuable insights and recommendations for complex problems. As an example, consider a medical expert system that assists doctors in diagnosing diseases based on patient symptoms and medical history.
One key feature of expert systems is their ability to reason and make decisions using a set of rules or heuristics derived from human expertise. These rules are typically represented in the form of if-then statements, which allow the system to evaluate different conditions and generate appropriate responses or actions. By utilizing these rule-based approaches, expert systems can handle large amounts of information and perform complex reasoning tasks efficiently.
To better understand the capabilities and potential impact of expert systems, it is important to explore some notable benefits they offer:
