Three substances of information: perception, essence, meaningThe article characterizes and interprets the concepts introduced in the theory of the information
field A.Denisov and the discrete version of this theory, which name– the informational approach to the analysis of systems: sensual information (perception information, element base, data), logical information
(essence or information potential) and their logical intersection, which in theory A.Denisov
corresponds to the category of information complexity, content, meaning. It is shown how these concepts
arose in the theory of the information field as a result of two laws of reflection — sensory and
logical, as they are interpreted in a discrete version of the theory. It is considered how the reflection of
objects or processes goes through several stages. During their passage, the term “information” is used
all the time, but until a more specific name of the perceived and / or transformed essence corresponding
to a particular decision–making process is found. Understanding this process makes the available
measures of information possible to more accurately use, as well as the mating terms “data (J) – concepts
(H) –knowledge (C)”. Such approach allows to determine the measures which can be entered for
measurement of the selected stages of information transformation based on deterministic and probabilistic
approaches, choosing them taking into account specific objectives and the conditions of application
of the theory of A.Denisov.

Information field theory of A. A. Denisov – 50 years50 years ago, in 1974, A. A. Denisov proposed a theory based on a dialectical generalization of the laws of functioning and development of systems of various physical natures, which he called the theory of the information field. The theory is based on the use of the apparatus of mathematical field theory to explain the laws of information reflection, which determined its name. Based on this theory, significant results were obtained for the study of motion control processes in continuous spatio-temporal and arbitrarily evolving situations. The use of this theory for the study of open distributed information systems seems promising. Subsequently, a discrete version of the theory was developed, which allows explaining the process of reflection and transformation of information and became the basis for the development of a number of practical applications, some of which are given in this article. This article characterizes the prerequisites for the emergence of this theory, the main ideas and concepts of the theory and its contribution that, over the 50 years, scientists and students united by the Scientific and Pedagogical School “System Analysis in Engineering and Control”, have made on the basis of this theory in the development systems theory, computer science and other sciences of systems. Information is provided on the application of A. A. Denisov’s ideas and the development of models for specific applications based on them. The authors of the article, including Anatoly Alekseevich’s students, was developing, appliing and are currently developing models of information theory of A. A. Denisov, proving the usefulness of theoretical knowledge for solving practical problems. Read more... |
