The tool to realize informatization and networking is actually intelligence. In modern information science and technology? More and more artificial intelligence technologies are used, such as natural language recognition and understanding, image recognition and processing, multi information sensing and control, knowledge representation, acquisition and processing, reasoning and solution, expert system, intelligent control and so on. Although the research of artificial intelligence has not made a major breakthrough in recent years. However, with the development of cognitive science and intelligent engineering technology. Artificial intelligence technology will be more and more applied to information science and technology.

2. Intelligence is the development direction of life science and technology
Human brain is the "headquarters" of human intelligence system, and brain science is the core of life science. Intelligence is also the development direction of life science and technology. The research of human brain will form intelligent science and technology, which is the science that drives the basic scientific research in the 21st century.

3. Intelligence is the development direction of automation engineering
Automation is an important means and condition of modern industrial development. It is no exaggeration to say that the process of modern industrial development is the process of continuously applying, improving and upgrading automatic production technology. At present, a variety of intelligent engineering systems and technologies are used more and more in various automation projects. The level and degree of application of intelligent technology in automation engineering determine the level and degree of automation of the project. Intellectualization has become the most obvious symbol of various engineering modernization.
