Expert systems, also known as knowledge-based systems, are computer programs designed to mimic the decision-making capacities of a human expert in a particular field. These systems use artificial intelligence calculations and knowledge databases to solve complex problems and make decisions in real-time.
An expert system consists of two main components: the knowledge base and the inference engine. The knowledge base contains a vast amount of information and expertise on a particular subject, such as medicine or engineering. This information is stored in the form of rules, facts, and examples. The inference engine is responsible for using this information to make decisions and provide suggestions.
Expert systems are designed to solve problems that are too complex for humans to solve alone. They provide accurate, consistent, and reliable results, as long as the information in the knowledge base is correct and up-to-date. Expert systems are used in a wide range of industries, including healthcare, finance, engineering, and manufacturing.
