Abstract:

Metadata of scientific publications are used to build catalogs, determine the citation of publications, and perform other tasks. Automation of metadata extraction from PDF files provides means to speed up the execution of the designated tasks, while the possibility of further use of the obtained data depends on the quality of extraction. Existing software solutions were analyzed, after which three of them were selected: GROBID, CERMINE, ScientificPdfParser. A procedure for comparing software solutions for recognizing texts of scientific publications by the quality of metadata extraction is proposed. Based on the procedure, an experiment was conducted to extract 4 types of metadata (title, abstract, publication date, author names). To compare software solutions, a dataset of 112,457 publications divided into 23 subject areas formed on the basis of Semantic Scholar data was used. An example of choosing an effective software solution for metadata extraction under the conditions of specified priorities for subject areas and types of metadata using a weighted sum is given. It was determined that for the given example CERMINE shows efficiency 10.5% higher than GROBID and 9.6% higher than ScientificPdfParser.

Abstract:

Currently, the major part of transmitted and stored data is unstructured, and the amount of unstructured data is growing rapidly each year, although it is hardly searchable, unqueryable, and its processing is not automated. At the same time, there is a growth of electronic document management systems. This paper proposes a solution for extracting data from paper documents considering their structure and layout based on document photos. By examining different approaches, including neural networks and plain algorithmic methods, we present their results and discuss them.

Abstract: DVM-system is designed for the development of parallel programs of scientific and technical calculations in the C-DVMH and Fortran-DVMH languages. These languages use a single DVMH-model of parallel programming model and are an extension of the standard C and Fortran languages with parallelism specifications in the form of compiler directives. The DVMH model makes it possible to create efficient parallel programs for heterogeneous computing clusters, in the nodes of which accelerators, graphic processors or Intel Xeon Phi coprocessors can be used as computing devices along with universal multi-core processors. The article describes the experience of the successful using of DVM-system to develop a parallel software code for calculating the problem of radiation magnetic gas dynamics and for research of plasma dynamics in the QSPA channel.

Abstract:

The article draws attention to the problem of measuring the effect that programming solutions have on the programming productivity and performance, in educational programming and the correctness-saving program improvements. The results of some experiments concerning these questions are discussed. The hypothesis that  functional models can provide a metric scale capable of separating features of programming languages and systems from features of programs and programming solutions is proposed. The results of a preliminary demonstrative experiment in studying the dependence of the program productivity upon the opted compiler and, on the other hand, upon the representation of the programming solution in the opted programming languages are described. Analysis of these results leads to a method that can reveal such dependencies. The long experience in sifting educational and contest programs revealed some unnoticed aspects of this problem.

Abstract:

The convection of matter in the Earth's upper mantle is considered, which in the Oberbeck–Boussinesq approximation is due to thermogravitational differentiation. Within the framework of this approximation, a 2-D numerical simulation of convective flows of the medium matter was performed. The equation for temperature follows from the entropy balance relation, where, due to taking into account the variable viscosity in the system, there is an effect of energy dissipation. The boundary conditions correspond to the assignment of the temperature generally accepted at the boundary of the upper and lower mantles, and for the lateral boundaries - their thermal insulation. At the asthenosphere–lithosphere boundary, assumptions were made that the heat dynamics is determined by its flow from the asthenosphere layer closest to the boundary, part of the heat dissipation along the boundary, and heat consumption for melting the lithosphere matter. Numerical solution of the constitutive equations is carried out in variables stream function - vorticity. An iterative scheme for their solution is given. The issues of software implementation of the numerical simulation apparatus are discussed. It is shown that under such boundary conditions, a quasi-periodic regime of heat oscillations is formed in the system under consideration.

Abstract:

This article is devoted to the study of the possibilities of optimizing the operability and improving the efficiency of complex multifunctional software systems using the example of free automated library and information systems (hereinafter - ALIS).

By 2023, the world has accumulated valuable experience in the creation and operation of integrated ALIS of various scales and purposes, but the issues of improving their design solutions remain relevant. First of all, this concerns the need to optimize the structure of the source code in order to increase its readability and maintainability, reduce the execution time of individual functional modules, and reduce the amount of RAM used.

As part of the study, a comparative analysis of the source codes of several existing open source databases implemented in various programming languages was carried out. The main approaches to the design of the code structure were studied, the most frequently used algorithms and patterns were identified. To assess the degree of optimization of the source code, a set of indicators was developed, including an assessment of the structure, readability, modularity and other characteristics. On this basis, individual code fragments were compared before and after the use of well-known refactoring techniques.

As a result of the work carried out, it was possible to identify the most common errors and shortcomings in the structuring of the source codes of the ALIS, to determine the main directions of their optimization. Data has been obtained on the possible reduction of testing and technical support costs by improving the quality of source codes.

Abstract:

The report presents the software package that will allow specialists in the field of architectural acoustics to choose the most appropriate methods for modeling sound and selecting finishing materials depending on the tasks and parameters of a building A distinctive feature of this system is the presence of an ontology of the subject area that describes the terms and relationships between concepts, as well as modules for solving various problems in the field of architectural acoustics. Such an approach will allow the user to recommend the most suitable simulation methods for one’s request due to considering the specifics of the premises and the functional requirements of the client. The on-demand software system allows to optimize and parallelize programs written in a domain-specific programming language. The paper describes the principles of source code analysis to identify critical areas and modify them using a bank of patterns. The report also discusses an approach to develop a domain-specific programming language based on domain ontology, ODSL (Ontology-Based Domain-Specific Language), which allows specialists to describe algorithms not accounting for different specific optimization and parallelization methods. The novelty of the work lies in the proposed architecture of modules based on applied ontology, which makes it possible to adapt the solution to other subject areas.

Abstract:

For support of adaptive training and educational analytics in the intellectual learning systems, it is necessary to collect, process data on progress of the student and his various individual characteristics. It can be realized by means of the student model. The analysis of approaches to modeling of the student has shown that application of several types of models is an optimal solution, considering requirements to the learning system. Three approaches were chosen and united into one model: overlay, Bayesian network, error model. Use of overlay model allows to build individual trajectories of student training. Bayesian networks realize competence-based approach in training. The model of mistakes keeps track of wrong knowledge of the student and helps the student to correct them at early stages. The student model uniting in itself these approaches is more suitable for realization of the personalized training, allows to keep track of progress of the student according to various characteristics and also gives the chance to easily submit the card of subjects, knowledge, competence of the student of various areas in the form of the count that is quite convenient and clear representation.
