In this connection, the task of automated formation of ontologies is\u0000 quite urgent. The most common quality criterion of the ontology is based on the\u0000 assessment of the convenience and efficiency of working with it, and the presence of a\u0000 connection between cognitive and semantic processes, which contributes to the process of\u0000 its construction and actualization. The main difference of the conducted analysis, the\u0000 results of which are presented in this work, are cognitive information technologies of\u0000 the subject area, cognitive-semantic analysis based on the theory of categories,\u0000 mathematical logic and universal algebra, construction of an ontological dictionary and\u0000 ontological constructions. The informational interaction of the intellectual environment\u0000 of the object with the subject is defined. For the formation of the concept in the\u0000 intellectual environment due to the attached information space, the possibility is\u0000 determined and the application of the concept and its features within the framework of\u0000 the problem is substantiated. The construction of ontologies is based on the connection\u0000 of cognitive processes with semantic ones and actualization – description and\u0000 identification of sources of cognitive information in intellectual environments of\u0000 subject areas.

Using fractal modeling for\u0000 dynamic stochastic systems made it possible to single out two statistical multipliers,\u0000 GN and FZ, based on the difference between the ways of particle interaction (GN) and\u0000 considering the system’s motion as such in the phase space (FZ). These multipliers form\u0000 the basis of physical statistics based on a deep understanding of the types of\u0000 interactions and their consequences. In addition, it is shown that the physical\u0000 statistics multipliers GN and FZ have different content when applied to systems with a\u0000 quantum nature of interactions or other phase space elements. As a result, the idea\u0000 arose about the possibility of forming fragmented physical statistics, which would\u0000 differentiate both the interactions between the particles of systems and individual\u0000 elements of the phase space, aiming to highlight the general patterns inherent in their\u0000 particular states. The present paper is devoted to forming such fragmented physical\u0000 statistics and the individual results of its application. The main asset of the proposed\u0000 method for considering statistical problems is the rethinking of the phase space of\u0000 dynamic stochastic systems, in which one can single out (as a separate element of the\u0000 phase space) the space of solid angles of orientation of momenta (or wave vectors) of\u0000 system particles. Accordingly, an additional component of the entropy of systems in\u0000 certain states appears – the orientational component of entropy. The only reason for the\u0000 appearance of an additional orientation component of entropy in all cases is the\u0000 mechanism of mono energization of the particle spectrum, the physical nature of which\u0000 can be very diverse. However, the statistical result is always the same: a sharp\u0000 increase in the orientation component of entropy with the emergence of a direction\u0000 distinguished in the system. The selected direction can be inherent in the system or\u0000 imposed on it by external influence – then we will call such ordering in systems\u0000 generation. If the selected direction arises spontaneously, then we will call it\u0000 self-ordering process. Often such a self-ordering process is also stochastic, such as\u0000 turbulence. The paper’s conclusion is as follows: the increase in entropy in systems\u0000 occurs not only when they approach the state of equilibrium but also when self-ordering\u0000 processes appear in them.","PeriodicalId":321731,"journal":{"name":"Management of Development of Complex Systems","volume":"282 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125881892","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
