An Expert system is a domain in which Artificial Intelligence stimulates the behavior and judgement of a human or an organisation containing experts. It acquires relevant knowledge from its knowledge base, and interprets it as per the user’s problem. The data in the knowledge base is essentially added by humans who are experts in a particular domain. However, the software is used by non-experts to gain information. It is used in various areas of medical diagnosis, accounting, coding, gaming and more.
Artificial intelligence
Breaking down an expert system, essentially is an AI software that uses knowledge stored in a knowledge base to solve problems. This usually requires a human expert, and thus, it aims at preserving human expert knowledge in its knowledge base. Hence, expert systems are computer applications developed to solve complex problems in a particular domain, at an extraordinary level of human intelligence and expertise.
