Abstract: — The structure of an intelligent information system that has been designed to protect the network information system from unauthorized external influences by various parrying means is described. The conditions for the stable functioning of the network information system are presented. An optimization problem has been formulated, which consists in the need to minimize the negative external influence on the network information system using parrying means of the designed intelligent information system. This problem has been divided into four subproblems, analytical models have been created for their solution, algorithms have been developed, and two examples of analytical solutions of problems of optimal distribution of negative external influences by the elements of the network information system without taking the mutual influence of system elements into account and taking them into account are shown.

Abstract: Abstract— The popularity of the use of the quartile index in various fields of knowledge is shown; the first mention dates back to the work of R. Kempton and L. Taylor on population biology, published in 1976 in the journal Nature. This index was proposed for the first time for scientometrics in 2019 by the historian A.V. Grinev from St. Petersburg. A number of improvements have been made to this index for the purpose of monitoring and evaluating the qualitative structure of publications by authors and any subjects of publication activity. It shows its significant advantage over Hirsch-like metrics and gives recommendations for its implementation in national and institutional systems for assessing the quality of publication activity.

Abstract: — This study analyzes the half-lives of all journals from the 1997–2018 period that were included in the Journal Citation Reports (JCR): Science (JCR-SE) and Social Sciences (JCR-SSE) JCR Editions, and in some narrower branches of science specially distinguished on the basis of WoS subject categories. The findings show that the values of the Cited Half-Life (CdHL) and Citing Half-Life (CgHL) indicators are almost always positive over the entire 22-year study period and for the entire global body of journals in the JCR, individual JCR editions, and each of the specially compiled sets of All Journals and Core Journals. They confirm the long-established fact that the CdHL and CgHL depend on the branch of science and characterize that branch and demonstrate that half-life values for social sciences and humanities are generally higher than for hard sciences. A correlation between half-life values and journal impact factors and numbers of Citable Items (articles, reviews, and conference proceedings that can be cited) is clearly shown. These features of half-lives are important to consider when goal setting and forecasting the development of scientific research. PubDate: 2021-07-01

Abstract: An intellectual system has been created that implements the JSM method of automated research support for the task of predicting the risk of pelvic organ prolapse in women with a history of birth through the birth canal. Methods for expanding fact bases are applied. For the first time, a lattice of strategies formed by predicates of simple similarity, difference, and similarity-difference (a, ad0, ad2) has been implemented and an algorithm for optimizing the replenishment of the fact base that uses the value of explainability has been proposed. Three experiments that were carried out according to the same scheme are described; in the second experiment, noise was removed when analyzing a subset of the initial data. New tasks have been formulated that allow further improvement of research results. PubDate: 2021-07-01

Abstract: Abstract— In this article we consider a fundamentally new information-theoretic approach to the classification of scientific texts based on compression algorithms. An analysis using the example of the comparative classification of full-text documents from arXiv.org and short annotations from Scopus showed that the accuracy of the proposed method is 87–92% and, in general, is not inferior to the existing ones. These conclusions were confirmed by an expert assessment. PubDate: 2021-07-01

Abstract: Abstract—Topical aspects of modern computer science in their relation to the issues of analysis of technical and economic information and econometric research have been investigated. The feasibility of abandoning the methods of classical statistics and applying robust and nonparametric data processing procedures in real conditions of the heterogeneity of observations and significant deviations of empirical distributions from the normal law is justified. The possibilities and areas of application of econometric models, methods of nonparametric statistics, science metrics, and multidimensional data analysis, for production of information-analytical products and services are shown. The prospects of analytical postprocessing of techno-economic information in the structure of big data technologies are considered. The purpose of this article was to show the potential and systemic role of analytical post-processing of technical and economic information in the formation of a new digital information environment.

Abstract: On the basis of the analysis of the functioning of complex special-purpose information systems, a general approach was proposed to their mathematical modeling and structural decomposition, based on topological constructions using the theory of the final semigroups. The connection between any transformations of a complex system in the finite space of its states and certain valid coordinatization variants is defined for the final semigroups. Various generalized indicators of evaluation of functional structure simplexes, which allowed one to obtain the characteristics of these complexes, have been determined. The proposed method of analysis allowed more objective analysis of the q-connectivity of the simplexes and the observability and controllability of the special-purpose complex information system. Definitions, theorems, and proofs are presented, which allows calculation of the sequence of composition and the integration of the subsystems of a complex system into a single whole.

Abstract: This paper describes the procedures and specific features of application of a new method of automatic classification based on calculation of deviations of stop-words distribution from Zipfian score. To neutralize discrepancies in texts lengths the author describes and applies the text undersampling methodology. The concept of an iterative threshold level is introduced to reduce text dimensionality to several dozen units. To evaluate the method’s efficiency the author has developed discriminative and similarative powers indicators that underlie the generalized efficiency score. Fourteen tests have been conducted, including comparison with the cosine similarity measure, that proved high efficiency of the proposed method for the solution of the tasks of authorship attribution of texts of fiction and clusterization of political texts.

Abstract: — This article describes a category theoretic approach to projections of semilattices as an alternative to the classic approach of pattern structure projections. In the special case of Cartesian products and their projections on partial sub-products, this approach forms the basis for a sequential version of the VKF machine learning method that is based on a binary similarity operation.

Abstract: Abstract Some ways to apply intelligent data analysis (IDA) to improve the reliability of computer data analysis in medical diagnostics and decision making are discussed. The procedure of IDA results in constructive falsification (refutability and reliability checking) with respect to collected empirical data is proposed. The approach is illustrated by medical diagnostics and decision-making examples. The effectiveness and practical significance of the proposed approach is demonstrated by examples of diagnostics of human brain tumor pseudoprogression. PubDate: 2021-05-01

Abstract: The functional dependence of the values of the terms and ionization potentials of atoms and/or dimers on the information-energy codes of photons interacting with matter is revealed on the basis of absorption spectra, which characterize the physicochemical properties of matter and represent information of a related type determined by self-consistent codes of the source and receiver of information. The tangential function for the systematization of electronic terms in the informational model of quantization (IMQ) has shown the periodic nature of the functions with self-consistency of the photon codes with the codes of atoms in the Periodic Table of Elements. A hypothesis has been proposed about the “subjective” interaction of a photon with matter; an approximation of the ionization potentials of atoms was carried out on the basis of a unified criterion. Extrapolation of the terms and ionization potentials of dimers showed that all the terms observed in absorption fit into series similar to Rydberg terms, and taking the multiplicity into account, certain of their sums form series with different regression coefficients characterizing the intemers (possible valences of dimers). The information component of the interaction of light and matter has revealed real prospects for the development of a new theory of quantum optics and the systematization of large spectroscopy databases.
