The theory of the information field and information approach to systems analysisThe article is devoted to the memory of outstanding Russian scientist Anatoly Denisov (1934-2010). Denisov made a considerable contribution to the development of systems theory and systems analysis, information theory and applied computer science. The theory of the information field and information approach developed by Denisov provides a unified management processes description in economy, politics, science, and education. He elaborated the concept of a system macroeconomic modeling and contributed to the development of a new information analysis trend with respect to physical systems and, in particular, gravity systems.

This article describes the main contribution of the school «System Analysis in Engineeromg and
Control» to the development of informatics, the theory of information systems and technologies. The
following results are briefly characterized: clarification of the notion of «information», the application
of the definition of a system, which based on the system-target approach, to justify the multilevel
structure of the information complex; the proposed classifications of information systems and technologies,
the concept of virtual information system.
The state of development of the theory of information systems and processes is analyzed. It is concluded
that further research is needed on the development of the structure, patterns and principles of
the creation and organization of the functioning of information systems based on the use of information
technologies of the third and fourth industrial revolutions, improving the methods of information
retrieval based on the semantic analysis of textual information on the basis of mathematical logic and
mathematical linguistics in order to increase relevance.

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.
