  • The rubrication of new areas of research in connection with the needs of
           the national economy based on the example of spintronics in physics
    • Authors: N. M. Builova; V. Yu. Zitserman
      Pages: 215 - 222
      Abstract: Abstract This article deals with problems of rubrication of dynamically developing directions associated with the permanent appearance of new objects, processes, methods, and technologies. These problems are considered based on the example of spintronics, a new field of solid-state physics that concerns the preservation and transmission of information according to electron spins in addition to or instead of their charge. We described a multi-level rubrication for spintronics, which includes all its major development directions at the moment, in accordance with which the publications are distributed in issues of the Physics. Spintronics AJ. A comparison of the proposed rubrication with the one that was proposed several years ago during the creation of a profile AJ was made. Among others, two new and promising branches of spintronics were allocated in the new rubrication: valley electronics (or valleytronics) and magnonics, and rubrics were introduced that reflect the roles of nano-objects and nano-technology in spintronic devices. The bibliometric analysis allowed us to evaluate the extent and distribution on different criteria of a publication flow in spintronics and to determine the adequacy of the developed rubrication.

           diagnostic tests
    • Authors: A. E. Yankovskaya; A. V. Yamshanov
      Pages: 223 - 236
      Abstract: Abstract In this article the relevance of using test methods of pattern recognition while developing intelligent systems for decision making support for various problem areas is discussed. The advantage of fault-tolerant diagnostic tests used in intelligent systems is shown, namely, a tool for registering and processing different kinds of errors in databases and knowledge bases. The results of testing two algorithms for constructing the nonredundant matrix of implications are compared; the technical particulars of program implementation are discussed such as synchronization means, test environment, test-program structure, and bottlenecks of program implementation; methods of their elimination, and further development of parallel algorithms.

    • Authors: S. M. Gusakova; M. A. Mikheyenkova
      Pages: 179 - 188
      Abstract: Abstract Description of the structure of social systems, which is the ultimate goal of empirical social research, presents a special difficulty in the case of qualitative (non-quantitative) data due to the difficulties of application of formal tools. Analysis of such data using the means of a JSM-type intelligent system (JSM Socio) allows one to create the structure of society based on a study of a system of relations that characterize it. In this paper we formulate and prove the conditions under which the potential hypotheses of the direct and inverse method of similarity in the JSM-method turn out to be real hypotheses. This allows for the selection of strategies of JSM-reasoning that are relevant to the available data.

  • A virtual scientific communication environment based on a semantic
           scientific information system
    • Authors: M. R. Kogalovsky; S. I. Parinov
      Pages: 189 - 194
      Abstract: Abstract This paper focuses on the principles and capabilities of a virtual communication system that facilitates new forms of scientific communications and evaluation of research productivity, as well as the specifics of its implementation based on the major Socionet open access research-information system. The innovative potential of the discussed environment is shaped by the use of a multi-aspect taxonomy of semantic linkages between the system’s information objects, their online declaration by the users, and the availability of a service to notify the authors of the objects being linked together of such event.

  • Etiological analysis as an approach to the detection of association
           networks in the case of a shortage of external information
    • Authors: T. G. Petrov; S. V. Chebanov
      Pages: 202 - 213
      Abstract: Abstract An approach to the enhancement of mental alertness in order to extract implicit knowledge and convert it into new information is considered. The approach is based on multifaceted analysis of certain objects, situations, problems, ideas, or confusions that appear to be important for a person or a legal entity. The distinctive feature of the approach is the formulation of a large number of “relevant” statements at the initial stage. Each of these statements is used to construct (1) a set of ”factors,” or statements that express the causes, the pretexts, and the conditions (including starting and boundary conditions) and (2) a set of “effects,” or statements that present the consequences, the results, the conclusions, novel requirements and/or suggestions concerning the conditions of implementation, etc. Each factor and effect is subsequently considered as a statement that requires analysis of the same type as the primary statements. The procedure is repeated until the factors and effects that were detected become limited by factors that are not amenable to further analysis or effects that can be regarded as boundary effects relatively to all other effects. The analytical procedure has been validated and is used to solve diverse tasks of pedagogics, to resolve conflicts, and to conduct research.

  • On determining semantic similarity based on relationships of a combined
    • Authors: O. L. Golitsyna; N. V. Maksimov; V. A. Fedorova
      Pages: 139 - 153
      Abstract: Abstract Problems of the use of thesauruses for fuzzy comparisons of conceptual patterns are considered. A measure of semantic similarity that can be calculated using hierarchical and association relationships of a thesaurus is proposed, as well as an algorithm to compile a semantic intersection of conceptual patterns based on the coinciding maximum principle. A massive of texts and conceptual search patterns of thesis papers was used for experimental studies, which proved that the use of the lexis of different subject fields of a multi-area thesaurus produced a more precise identification of sematic similarity. The power of the pattern intersection increased significantly through pairs of descriptors linked by the semantic similarity measure; however, the average degree of pairwise intersection only increased by 1–2%, which implies an insignificant “expansion” of a conceptual pattern as it is used as a search pattern in creating search-result outputs in automated search mechanisms.

  • Evaluation of the efficiency of the chi-square metric
    • Authors: V. A. Yatsko
      Pages: 173 - 178
      Abstract: Abstract The efficiency of using the chi-square metrics to weigh terms used in text documents is evaluated. The procedure includes the selection and advanced processing of class C and ~C texts, compilation of a reference dictionary and calculation of scores for all the terms in the dictionary, calculation of χ2 coefficients for terms from a class C text, and calculation of the general efficiency factor by the sum of the coefficients found for the terms from the reference dictionary. The weighting by the χ2 formula, odds-ratio (OR) formula, and on the basis of probabilistic variables is analyzed and compared. It was found that the best result is yielded by the OR-based weighting.

    • Authors: E. A. Pleshkevich

      Abstract: Abstract This paper considers the evolution of the development of a worldview in library-bibliographical and information-related research disciplines as part of communicative and computational information processes. It is proposed to consider a document as a form of institutionalized reliance on information and data as a form of information arrangement, followed by logical information processing. It is shown that a worldview is a diverse phenomenon that cannot be reduced to any specific form of information arrangement.

  • The foundations of modeling management processes for innovation projects

    • Authors: R. A. Faizrakhmanov; L. A. Mylnikov
      Pages: 84 - 90
      Abstract: Abstract A possible approach to constructing models for managing innovation projects in production–economics systems of enterprises and providing them with information support is described. The conceptual foundations for constructing models for innovation projects are presented, as well as the technique of transition from conceptual modeling to managing such projects. The obtained model and the set of parameters for project evaluation may be unique and depend on the specific features of the project, the preferences of the decision maker, and the production-economics system in which the project is carried out.

  • An information model of light quantization
    • Authors: N. V. Serov
      Pages: 91 - 103
      Abstract: Abstract This paper presents the basic ideas and concepts for the development of information models of optical objects. Quantitative ratios among regularities in trigonometric spectral analysis as a possible connection between the projection of natural (point-source) radiator and absorbing atomic section are shown. This approach has been applied to the correlation between these patterns and atomic spectroscopy (specifically, terms and ionization potentials of neutral atoms with s and p shells. This has made it possible to build information models of radiation and atomic absorption on certain principles of field continuum quantization.

  • The evolutionary factors, management, and efficiency of information
    • Authors: O. V. Syuntyurenko
      Pages: 117 - 125
      Abstract: Abstract This paper considers macro factors that determine the level of information support of the science and production domain. The trends of progress in the most advanced areas of Russia’s informatics are analyzed. The methodology and model of information-support management in all the phases of the research–development–production (R–D–P) cycle are considered. It is shown that the development of a design solution based on this model makes it possible to reduce the time lag and provide essentially improved information support in all the phases of the R–D–P cycle. Several proposals are formulated about overcoming the inertial trends in the development of the national information system.

  • An algorithm for information projection to an affine subspace
    • Authors: D. V. Vinogradov
      Pages: 133 - 138
      Abstract: Abstract We investigate an algorithm to find a point of an affine subspace in the positive orthant such that it is the closest one to the original point with respect to the Kullback–Leibler distance. This problem is solved by means of the classical Darroch–Ratcliff algorithm (see [1]), while we use ideas of the information geometry founded by Chentsov (see [2]) and Csiszar (see [3]). The main theorem of the present work proves the convergence of that algorithm (the method of the proof is different from previous ones). The proposed algorithm can be applied, e.g., to find the maximum likelihood estimates in an exponential family (see the last section of the paper).

  • An analysis of the results of the inductive formation of diagnostic
           medical knowledge databases
    • Authors: A. S. Kleshchev; M. V. Petryaeva; S. V. Smagin; M. Yu. Chernyakhovskaya
      Pages: 70 - 78
      Abstract: Abstract This paper proposes a problem-oriented method for the objective formation of easily interpretable knowledge databases for intelligent systems. We describe the InForMedKB software complex, which is designed for the inductive formation of medical diagnostics knowledge databases; it was used to perform the proposed method. Expert analysis of the results of using the developed software complex, viz., the inductively formed Acute Appendicitis database of medical diagnostic knowledge for a mathematical dependence model with parameters, which is near real-life ontology of medical diagnostics, is given.
