Artificial Intelligence's long-term goal is to build the human level of artificial intelligence. AI was born 50 years ago, in the bumpy road has made encouraging progress, in particular, machine learning, data mining, computer vision, expert systems, natural language processing, planning, robotics and related applications have brought good economic benefits and social benefits. Widespread use of the Internet is also exploring application of knowledge representation and reasoning, to build the semantic Web, improve the effectiveness of the rate of Internet information. The inevitable trend of information technology is intelligent. The intelligence revolution with the goal of replacing work performed by human brain work with machine intelligence will open up the history of human postcivilization. If the steam engine created the industrial society, then the intelligent machine must also be able to magically create a intelligent society to realize the social production automation and intelligence which promote the great development of knowledge-intensive economy.

Artificial intelligence is a branch of computer science, is a discipline to study of machine intelligence, that is to use artificial methods and techniques, developing intelligent machines or intelligent systems to emulate, extension and expansion of human intelligence, realize intelligent behavior. Artificial Intelligence in general can be divided into symbolic intelligence and computational intelligence. Symbolic intelligence is the traditional symbolic artificial intelligence, it is the basis of physical symbol system to study the knowledge representation, acquisition, reasoning process. Use of knowledge to solve problems is basic, the most important features of the current symbol intelligence, so people often put the current stage of artificial intelligence known as knowledge engineering. Knowledge Engineering research emphasis on knowledge information processing methods and technologies, and promote the development of artificial intelligence.
