  • Classification of Scientific Texts Based on the Compression of Annotations
           to Publications
    • Abstract: This paper describes the possibility of establishing the semantic proximity of scientific texts by the method of their automatic classification based on the compression of annotations. The idea of the method is that the compression algorithms such as PPM (prediction by partial matching) compress terminologically similar texts much better than distant ones. If a kernel of publications (an analogue of a training set) is formed for each classified topic, then the best proportion of compression will indicate that the classified text belongs to the corresponding topic. Thirty thematic categories were determined; for each of them, annotations of approximately 500 publications were received in the Scopus database, out of which 100 annotations for the kernel and 20 annotations for testing were selected in different ways. It was found that building a kernel based on highly cited publications revealed an error level of up to 12 against 32% in the case of random sampling. The quality of classification is also affected by the initial number of categories: the fewer the categories that participate in the classification and the more terminological differences exist between them, the higher its quality is.

  • On the Problem of Medical Diagnostic Evidence: Intelligent Analysis of
           Empirical Data on Patients in Samples of Limited Size
    • Abstract: This paper discusses the possibility of expanding the ideas of the validity of medical decisions of a diagnostic nature, which are made in the framework of so-called evidence-based medicine. An approach is proposed that allows building special data in the process of intelligent analysis of accumulated empirical data, which characterize the causality of a diagnosed effect–logical conditions (characteristic functions) that take the value true in all instances of the presence of the target effect and the value false for all instances of its absence in the training sample of precedents. This problem is solved based on the expanding sequences of training samples using: (a) a formal refinement of the concept of similarity of precedent descriptions as a binary algebraic operation, and (b) a mathematical technique for generating empirical dependences in the style of the JSM method of automated support for scientific research. The features and capabilities of the developed approach are described based on the example of solving the problem of analyzing the causes and predicting the pseudoprogression of brain tumors.

    • Abstract: —This paper considers the general and specific problems of multilevel synthesis of models of monitoring objects. These models satisfy the needs of domain experts for model building when solving forecasting and control problems, etc. The general problem can be formulated as a single-objective multi-constrained optimization problem. A set of synthesis efficiency criteria and indicators for assessing synthesized models is proposed. The specific problems of multilevel synthesis are determined in the context of the general problem definition and in terms of the developed set of indicators.

  • A Probabilistic Algorithm for Calculating Similarities
    • Abstract: In this paper, we describe a new probabilistic algorithm for calculating hypotheses as the results of similarities between training examples for a machine learning problem based on a binary similarity operation. Unlike previously proposed probabilistic algorithms, the order of accounting for training examples is fixed for all hypotheses. This algorithm is useful for implementation using a GPGPU. The main result of this paper is the independence of the order of the appearance of training examples of the probabilities of each similarity in the sample.

  • Intellectual Mining of Patient Data with Melanoma for Identification of
           Disease Markers and Critical Genes
    • Abstract: Genotypic (DNA mutations) and phenotyping data on patients with melanoma are analyzed to identify markers of early disease diagnosis and critical involved genes. An optimal mining method was chosen from those that are traditionally used in the field. This method allows one to analyze a set of terms. Automatic and interactive approaches were performed, which both allow a considerable reduction in the computational requirements. New melanoma-associated genes and candidate relapse markers were identified. Data mining was performed with the JSM method of automated support of scientific research (JSM ASSR).

  • On the Heuristics of JSM Research (Additions to Articles)
    • Abstract: The logical means of detecting empirical regularities using the JSM method of automated research support are considered. Generators of hypotheses about the causes and hypotheses about predictions that are stored in sequences of expandable fact bases are determined. Many “histories of possible worlds” are considered, where “world” refers to an expandable fact base. This set is used to determine empirical regularities, that is, empirical laws, tendencies, and weak tendencies. Empirical regularities are used to determine empirical modalities of necessity (for empirical laws), possibilities (for empirical tendencies), and weak possibilities (for weak empirical tendencies). The Propositional calculi of the class ERA are proposed, that is, modal logics with two empirical modalities of necessity and possibility such that they imitate abductive inference through the axioms of abduction (◻(p → q) & Tq) → ◻p), (◇(p → q) & Tq) → ◇p), where ◻, ◇, T are operators of necessity, possibility, and truth (“it is true that…”). A series of definitions related to the characterization of data mining using heuristics of the JSM method of automated research support is given.

  • Comparison of Research Results by Scientific Communities
    • Abstract: — In the article, the issues of normalization of scientometric indicators of the publication level were studied. An integrated approach to the evaluation of research results was formalized. The similarities and differences between professional and scientific communities were considered. The concept of a professional scientific community was introduced. Local and network subtypes of scientific communities were identified. A method has been developed for obtaining the values ​​of scientometric indicators normalized by both local and network scientific communities, the distinguishing feature of which is the use of linguistic variables and production rules of fuzzy logic. The testing of the proposed methodology was carried out based on the example of a scientometric database.

  • Conceptualizing the Predicates of the Goethe–Newton Controversy
           about Color
    • Abstract: — The Goethean opposition of light and darkness is presented as a chromatic conceptualization that involves constructing information models for quantization of radiation, reflection, transmittance, absorption, and refraction of light by matter by introducing tangential functions, which made it possible to establish the relationships between absorption and refraction of light. The principle of retaining information in the light stream led to the derivation of the relevant formulas. The relationship between the mind and the environment in the interaction of a light stream with matter is formalized.

  • Semantic Search Tools Based on Ontological Representations of Documentary
           Information
    • Abstract: Ontological means of identification and representation of text documents semantics in relation to the problems of interactive information retrieval are considered. The implementations of ontologies operations are presented, which allow forming images of new meanings in the subject area. Taxonomies of relations (paradigmatic and syntagmatic) and entities (polythematic thesaurus of concepts) are used to perform operations, as well as to identify fuzzy relationships (in the case when entities and relationships are specified at different levels of generality and/or expressed by different linguistic constructions). Interactive tools are proposed that use the operation of constructing aspect projections for graph representations of ontologies, which make it possible to reduce the dimension of the graph to a level acceptable from the point of view of display and perception. The possibilities of context-based use of entities and relationships for the development of the search process are considered. This paper discuses the use of ontology graphs of organizational processes as a “navigation map” that provides new entry points in the graphical interface, that is, objects that will be contextually defined patterns of search queries in similarity selection tasks or expert analysis tasks. This allows one not only to increase the completeness and accuracy of information retrieval, but also to make the scheme of search navigation more natural, bringing it closer to the schemes of understanding and synthesis of knowledge.

  • The Algebra of Hidden Relations as a Means of Modeling Statistical
           Databases
    • Abstract: — An analogue of relational algebra is considered that is used to model databases when attribute values are not completely visible to the user but only up to a certain equivalence relation on domains. This case is important for so-called statistical databases, when it is necessary to provide and comprehensively analyze the summarized information on data stored in a database, but the user does not have access to personal data in the database. Similarly to the relational approach, this case introduces the concept of a hidden relationship and a system of operations with hidden relationships. Some correlations between these operations are shown and the query language is defined.

  • A Method for Digital Twin Generation Based on the Aggregation of
           Information Objects
    • Abstract: — The development of information models of physical systems posed the problem of generating a digital twin. A fully-functional digital twin can be created if many of its projections interact simultaneously. The projection interaction problem is due to a set of approaches to decomposing a real-world object and aggregation of an information object. It is proposed to establish relationships between projections by detecting shared data flows using collinear structures.

  • The Ancestral Homeland of the Carriers of the Proto-Indo-European
           Language: Mathematical Models for the Study of Linguistic Information
    • Abstract: Abstract—This paper presents the results of theoretical analysis and computer modeling, which suggest that two main linguistic populations characterized today as the division of Indo-European languages into the so-called “satem-centum” language ranges could emerge in the model Indo-European language community approximately 3500–4000 years ago. The results of computer modeling show that among the two main hypotheses of the formation of the Proto-Indo-Europeans (the Anatolian and Kurgan hypotheses), the latter corresponds to the time estimates we obtained to a greater extent. Some of the problems of the search for the ancestral homeland of the peoples that were carriers of the Proto-Indo-European language are analyzed.
