Shannon, the founder of information, thinks that "information is used to eliminate random uncertainty", which is regarded as a classic definition and quoted by people.
Norbert wiener, the founder of cybernetics, thinks that "information is the content and name that people exchange with the outside world in the process of adapting to the outside world and making this adaptation react to the outside world", which is also cited as a classic definition.
Economic management experts believe that "information is effective data to provide decision-making". Josiah Willard Gibbs, a famous American physical chemist, founded vector analysis and introduced it into mathematical physics, which found a new angle for studying the uncertainty and contingency of events, thus making mankind take the first step in grasping information scientifically. He believes that "entropy" is a measure of the lack of information in physical systems.
Electronics and computer scientists believe that "information is a signal transmitted in electronic circuits".
Professor Zhong Yixin, a famous informatics expert in China, believes that "information is the way of existence or the state of motion of things, which is directly or indirectly expressed in this way or state".
American information management expert F.W.Horton defines information as: "Information is processed data to meet the needs of users' decision-making. "Simply put, information is processed data, or information is the result of data processing.
According to the research results of information. The scientific concept of information can be summarized as follows:
Information is the reflection of the movement state and change of various things in the objective world, the representation of the interrelation and interaction between objective things, and the representation of the movement state and change essence of objective things. Reflect the internal attributes, state, structure, mutual relationship and interaction with the external environment of things, and reduce the uncertainty of things.
