Information science is a comprehensive subject that studies information. Its English name is also information science or informatics, which is a complex scientific group and is in the process of unification and systematization. Information science is based on information theory, which only studies the characteristics of information dissemination, not the characteristics of information dissemination, and does not involve the knowledge content, value or semantics of dissemination. Information science not only cares about the information structure and form in communication, but also cares about the knowledge content in communication. There is a special branch of information science-information research, which studies the transferred knowledge content, analyzes the horizontal trends of various disciplines and majors, makes appropriate induction and synthesis, and provides support for various decisions. However, people still believe that information science can provide some theoretical support for information science, for example, it provides a clear method to deal with information concepts in messages. Information science should fully absorb and make use of the achievements of information theory to improve the efficiency of information transmission.
Computer science is a science that further explores and theoretically studies software, special applications (artificial intelligence), computer mathematics and computer architecture through the study of information processing process. It is a tool, and there is a close cross relationship between computer science and information science. The wide application of computers in information activities has greatly changed the work and means of information collection, processing, storage, retrieval, transmission, development and utilization. It has changed the traditional concept and service mode of libraries and intelligence agencies.
There is a close relationship between philology and library science, and philology or literature work is one of the foundations of information science, so library science and information science are also closely related. However, information science has now gone beyond the traditional stage of focusing on record carriers and paid attention to human knowledge exchange in a broad sense. Generally speaking, the focus of library work is book collection, cashier, reading and so on. The information center focuses on processing, reporting, researching and even providing all kinds of information, and requires the disclosure of the contents of every document or even every data. Bibliography is an important branch of library science, while information science focuses on summarizing, indexing and summarizing the contents of documents. The number of books is an important symbol to measure the scale of a library, and the information center takes the number of document processing, the quality of comprehensive information analysis, and the timeliness and effectiveness of information service as an important symbol to measure its work.
Scientology takes the overall activities of science and technology as the research object, mainly studying the structure, mechanism and trend of science and technology development and its relationship with politics, economy, culture, society and other related fields. It is the product of the intersection of natural science and social science, and it is a new comprehensive discipline. However, the development of science and technology is inseparable from academic exchanges. After a research topic is determined, we must first check the literature. The concrete embodiment of scientific and technological development is that talents produce achievements, and talents and achievements will eventually be shown in the literature, which are some key issues of information science. Therefore, information science is closely related to science of science. For example, scientometrics is a branch of scientism, and there is also so-called bibliometrics in information science, the contents of which are the same or close. Only the former focuses on scientific management decisions, while the latter focuses on scientific information management.
The relationship between management and information science is also very close, and information management is a part of management. The leaders of the government, enterprises or institutions must have information and intelligence to make judgments and decisions in complex situations, and subordinate institutions should constantly feed back the situation to their superiors in the process of implementing decisions. In order to make all kinds of information inside and outside the department unimpeded, it is necessary to manage the information flow scientifically in order to make correct decisions and implement them smoothly.
In the process of intelligence activities, advanced technical means are used, so it is also closely related to hard sciences such as physics, machinery, electrician and electronics. In addition, information science is closely related to cybernetics, communication, linguistics, semantics, psychology and social economics.
