Artificial intelligence (AI) is a subdivision of computer science. Its purpose is to develop theory and method to create “intelligent” computer programs that work in a human-like way, rather than subjecting human user to the stereotyped computer-dominated working style. In a sense of analogy(模拟), human intelligence is added to computer programs which then exhibit more extensive ability, for example, thinking and reasoning, acquiring knowledge and applying it to solving more complex and difficult problems that present computer can’t.

Expertise is derived and organized in its knowledge base ready for the user to retrieve. Today, many expert system have been commercially available and, and more are under development.
