    3. 3 Definition :- Artificial intelligent :The branch of computer science concerned with making computers behave like humans. The term was coined in 1956 by John McCarthy at the Massachusetts Institute of Technology

    4. 4 AI Context

    5. 5 Artificial intelligence method games programming : computers to play games such as chess and checkers expert systems : programming computers to make decisions in real-life situations (for example, some expert systems help doctors diagnose diseases based on symptoms) natural language : programming computers to understand natural human languages neural networks : Systems that simulate intelligence by attempting to reproduce the types of physical connections that occur in animal brains robotics : programming computers to see and hear and react to other sensory stimuli

    6. 6 Expert Systems Definition: An Expert System is a system that employs human knowledge captured in a computer to solve problems that ordinarily require human expertise, early attempt by mind in 1960

    10. 10 Expert Systems in Medicine An ...has a large database of knowledge. ...allows the database to be interrogated. ...has a set of rules (inference engine) for making deductions. An expert system is a computer system which simulates the knowledge and expertise of a human expert.For example, in Medicine, expert systems are being used for disease diagnosis.The patient's details and symptoms are input, and the system outputs probable diagnoses, recommended treatments or drugs which may be prescribed.  Expert systems are not really replacing doctors but are being used to help them. There are ethical and legal reasons for this - if a computerised diagnosis is wrong, who do you sue? Some patients would feel happier typing medical information into a computer than discussing it with a human doctor...but others would prefer the 'human' touch.   The advantages of an expert system over a doctor are... ...a large database of knowledge can be added to and kept up-to-date - it can store more knowledge than a person. ...the system cannot 'forget' or get facts wrong. ...it survives forever. There is no loss of knowledge as there is when a doctor retires. ...the computer can access specialist knowledge that a doctor may not have. An expert system would be programmed using an (AI (Artificial Intelligence language such as PROLOG.
