It uses a large collection of rules and facts to answer questions or solve problems. For example, in healthcare, an expert system can look at symptoms and suggest what illness a patient might have\u2014just like a doctor would.<\/p>\n<p>The system has two main parts. First is the knowledge base, which stores all the expert information. Second is the inference engine, which uses logic to apply that knowledge to new problems. Together, they work like a smart decision-maker that never forgets anything and always gives the best answer.<\/p>\n<p>Expert systems are used in many areas like medicine, law, engineering, and customer support. They help people make fast and correct decisions without needing a human expert all the time. This saves time, reduces mistakes, and brings expert-level advice to more people.<\/p>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>In this Expert System Tutorial, we will learn what is Expert System in Artificial Intelligence.
