Jong Li's poem "Missing an Old Friend in Late Spring" in the Southern Tang Dynasty: "Dream breaks beauty's emphasis on information, and the eyes are leaning against the balcony for a long time." Song Chen Liang's poem Plum Blossom: "If you want to spread the words of spring, you are not afraid of snow burial." The fourth and fourth chapters of the Water Margin: "Sung River was overjoyed and said,' Brother Xian can go quickly and know his information in ten days.' "Ba Jin's Trinity of Home:" What happened to my second cousin? Why didn't you even give me a message? "
2. Information theory refers to the report transmitted by symbols, and the content of the report is unknown to the receiver of symbols in advance.
Chen Yuan's Sociolinguistics 4. 1: "According to the concept of physics, information is just a signal sequence arranged in a certain way. In social communication activities, this definition is not enough: information must also have a certain meaning, or information must be a' carrier of meaning'. " Science Pictorial 1983No. 1: "The operation of the whole subway is controlled by a central computer, and the information it relies on comes from highly sensitive instruments installed on the inter-station lines."
3. The state of motion of things and statements about the state of motion of things.
Detailed definition of information:
Information refers to the objects transmitted and processed through audio, news and communication systems, and generally refers to all the contents spread by human society. People can distinguish different things by obtaining and identifying different information from nature and society, so as to understand and transform the world. In all communication and control systems, information is a common form of communication. 1948, the mathematician Shannon pointed out in his paper entitled Mathematical Theory of Communication that "information is used to eliminate random uncertainty". The most basic unit of the universe to create everything in the universe is information.
The most basic unit of the universe to create everything in the universe is information.
Information is a collection of things and their attributes. Information is information, and information is the representation of matter, energy, information and its attributes. Information is an increase of certainty. That is, positive confirmation. At present, the definition of information is often too broad, and interpretation is often regarded as a definition. Therefore, the definition of information needs to be standardized and standardized. The definition of "genus plus species difference" is a standardized model of information definition. According to the standard of "definition", the information definition is established. Follow the concept of "definition" to formulate "information definition", and don't mistake "information interpretation" for "definition".
Extended data:
The word "information" refers to information in English, French, German and Spanish, information in Japanese, information in Taiwan Province Province and ancient telegrams in China. As a scientific term, it first appeared in the article "Information Transmission" written by Hatle in 1928. In the 1940s, C.E.Shannon, the founder of information, gave a clear definition of information. Since then, many researchers have given different definitions from their respective research fields. The representative expression is as follows:
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".
scientific terminology
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 mastering information in science. 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.
