What is the origin of information?

Although information has become a very popular term, its definition has not been unanimously recognized. There are roughly the following statements:

1 Information is the content transmitted by means of language, characters, numbers, symbols, images, sounds, scenes, expressions and states.

2. 1948 Shannon, one of the founders of information theory, first defined "information is the decrease of entropy" in the form of information theory formula, and the "entropy" used here is the measure of uncertainty. Shannon's definition of information actually means that information is "used to eliminate uncertainty".

3. Weiner, the founder of cybernetics, pointed out in 1948 that "information is information, not matter or energy". It is pointed out that information is the third resource different from matter and energy.

Some people say that information is the general form of things, and information is news, which emphasizes the knowledge of information.

5. Some people emphasize the function of information, develop the definition of information of Xiannong, and put forward that information is news with new content and new knowledge.

6. Others emphasize the relationship between information and communication, and further form three views:

(2) "Semantic information" means that information is a sign that people adapt to the outside world and exchange content with the outside world.

Such as all kinds of knowledge and skills.

(3) "Value information" means that information is knowledge with the characteristics of value, effectiveness and economy.
