Abstract:

The most common approach to creating an HTML version of a journal article among scientific publishers is to first create an XML version of the article in accordance with the NISO Journal Article Tag Suite (JATS) standard, followed by automatic conversion to HTML and PDF formats. However, obtaining an XML version from a manuscript in the .docx format of the MS Word word processor, often used by authors, when it contains a large number of complex formulas and tables is a difficult task. The existing software either does not cope with it in full or is expensive and inaccessible to small publishers with a limited budget. This paper proposes an approach to creating an HTML version of a journal article from a manuscript in .docx format containing formulas in MathType format, which does not require significant financial and time costs from the publisher. It also describes a currently implemented prototype of an underlied this approach converter of scientific articles from .docx format to HTML and JATS XML formats, which is applicable for KIAM preprints.

Abstract: A number of problems related to the construction of the metadata factory of the digital mathematical library Lobachevskii-DML have been solved. By metadata factory we mean a system of interconnected software tools aimed at creating, processing, storing and managing metadata of digital library objects and allowing integrating created electronic collections into aggregating digital scientific libraries. In order to select the optimal such software tools from existing ones and their modernization:we discussed the features of the presentation of the metadata of documents of various electronic collections related both to the formats used and to changes in the composition and completeness of the set of metadata throughout the entire publication of the corresponding scientific journal;we presented and characterized software tools for managing scientific content and methods for organizing automated integration of repositories of mathematical documents with other information systems;we discussed such an important function of the digital library metadata factory as the normalization of metadata in accordance with the formats of other aggregating libraries.As a result of the development of the metadata factory of the digital mathematical library Lobachevskii-DML, we proposed a system of services for the automated generation of metadata for electronic mathematical collections; we have developed an xml metadata presentation language based on the Journal Archiving and Interchange Tag Suite (NISO JATS); we have created software tools for normalizing metadata of electronic collections of scientific documents in formats developed by international organizations – aggregators of resources in mathematics and Computer Science; we have developed an algorithm for converting metadata to oai_dc format and generating the archive structure for import into DSpace digital storage; we have proposed and implemented methods for integrating electronic mathematical collections of Kazan University into domestic and foreign digital mathematical libraries.

Abstract:

In recent years, the presentation of full-text scientific articles in HTML has become widespread. This format offers several advantages for online publication compared to the traditional PDF format, owing to its more advanced tools for structuring material, embedding multimedia content, and implementing various interactive and dynamic features. Therefore, the task of converting manuscripts from the traditionally used MS Word and LaTeX formats into a high-quality HTML version capable of realizing the advantages of this format has become relevant. This paper presents the results of applying the approach for converting scientific articles from MS Word to HTML, proposed in previous studies, to Keldysh Institute of Applied Mathematics’ preprints. The interactive capabilities of the resulting HTML versions are described.

Abstract:

Along with the traditional form of electronic presentation of full texts scientific articles – the PDF format, the HTML format has become increasingly widespread in recent years. It has a number of advantages for online publications due to the available means for better content structuring, adding multimedia and implementing of various interactive and dynamic features. In this regard, the task of getting an HTML version of a scientific article from the original format sent by the author becomes highly topical. The article discusses various approaches to preparing HTML versions of full texts scientific articles and describes the software used in this process. The main attention is paid to the tools used for source materials in the Word format.

The paper also outlines the basics of the JATS XML standard, which is widely used in the preparation of online publications of journal articles.

Abstract:

In this paper, we describe a way to use UML diagrams for configuring web-application’s behavior. That is, using the configuration will determine the behavior of the system, the transitions between the screens, as well as the business logic of application. We examine and compare various UML diagrams for their possible features. A web framework for ASP.NET Core is developed, which uses the UML diagram to form a configuration in the XML or JSON file formats. Configuration will determine the behavior of the system. In addition, we describe further steps in using and developing the web-framework.

Abstract: Пространства имен XML обеспечивают простую методику получения имен элементов и атрибутов, используемых в документах Расширенного Языка Разметки, что достигается путем ассоциации имен с пространствами имен, идентифицируемых с помощью ссылок URI.

Abstract: Currently, the need for distributed ML training solutions in the world is increasing. However, existing tools, in particular TensorFlow Federated, are at the very beginning of their development, difficult to implement, and currently suitable exclusively for simulation on servers. For mobile devices, reliable approaches for this purpose do not exist. This article has designed and presented an approach to such distributed training of the ML-model on mobile devices, implemented on existing technologies. It is based on the concept of model personalization. In this approach, this concept is improved as a consequence of mitigating the identified drawbacks. The implementation process is structured so that at all stages of working with the ML-model use only one Swift programming language (Swift for TensorFlow and Core ML 3 are used), making this approach even more convenient and reliable due to the common code base.

Abstract: An approach is proposed for organizing expert evaluation of a scientific document submitted to a mathematical journal. Domain restriction is associated with the use of the Mathematical Sciences Classification System – MSC. A recommendation system is presented that allows you to create a list of possible experts for conducting scientific peer-reviewing on a mathematical article. The recommender system uses the MSC codes presented by the author of the article on the MSC2020 classifiers. If the codes MSC2000 or MSC2010 are indicated in the article, they are automatically converted to codes MSC2020. For each expert, the system supports a personal profile that contains a set of codes MSC2020, supplemented by numerical characteristics – weights calculated for each code in accordance with the system of accounting for competencies, preferences or refusals to participate in the review procedure. This set is automatically edited if the expert is included in the list of possible reviewers – the weights of several codes increase or decrease, as well as new codes are added. The recommendation system is implemented as an integrated tool (plug-in) of the Open Journal Systems (OJS) platform. The developed method has been tested in the information system of the Lobachevskii Journal of Mathematics (https://ljm.kpfu.ru).

Abstract:

Methods for creating digital mathematical collections that include unstructured sets of documents are presented. These sets contain materials from scientific conferences, as well as articles from the archives of mathematical journals of the "pre-digital" period.

Using the software tools of the metadata factory of the digital mathematical library Lobachevskii DML, a mandatory set of metadata for digital collection documents was formed. To refine and replenish the metadata sets, knowledge extraction methods from Wikidata were used.

To search Wikidata for information about digital collection documents and their authors, a system of SPARQL queries has been developed. A set of Wikidata entities is defined, which determine the features of the search, as well as the subsequent filtering of the results.

Methods for clarifying and supplementing the bibliographic references given in the articles are proposed. When forming the metadata of documents of retrocollections, a search was made in Wikidata for information about the years of life of the authors of articles, as well as URLs of web pages with information about articles and their authors. The results of the formation of several new digital collections of the Lobachevskii-DML digital library are presented.

Abstract: The semantic markups of the World Wide Web have accumulated a large amount of data and their number continues to grow. However, the potential of these data is, in our opinion, not fully utilized. The semantic markups contents are widely used by search systems, partly by social networks, but the usual approach to using that data by application developers is based on converting data to RDF standard and executing SPARQL queries, which requires good knowledge of this language and programming skills. In this paper, we propose to leverage the semantic markups available on the Web to automatically incorporate their contents to the content of other web pages. We also present a software tool for implementing such incorporation that does not require a web page developer to have knowledge of any programming languages ​​other than HTML and CSS. The developed tool does not require installation, the work is performed by JavaScript plugins. Currently, the tool supports semantic data contained in the popular types of semantic markups “microdata” and JSON-LD, in the tags of HTML documents and the properties of Word and PDF documents.

Abstract:

The article provides an overview of existing digital publishing systems, existing ways to expand the functionality of such systems, and also proposes a project for a set of services to expand the functionality of the Open Journal Systems publishing system on the platform of the Lobachevskii-DML digital mathematical library. The proposed set of services includes services aimed at the authors of articles and intended for the editorial staff of the journal. The existing developments in individual parts of the project are described, and the main ideas for the development of all services are proposed.

Abstract:

The article describes approaches to replenishing metadata of documents in electronic collections of a digital mathematical library. An open resource of the semantic network is used as a replenishment. For this purpose, software tools have been developed to search for the necessary data and include it in a metadata set. A separate block of metadata in a scientific article is formed from the affiliation of the authors presented in the document. Typically, the ownership that occurs in a document does not contain sufficient data to generate a set of metadata. A method has been developed for providing author affiliation metadata, providing an open register of scientific organization identifiers (ROR), as well as means for making connections between ROR and other semantic chains. This method was applied to the collections of articles of the journal “Digital Libraries” for 2021–2022.

The article describes a method for connecting the Lobachevsky digital mathematical library-DML to new electronic collections, and describes a method for transforming metadata into a digital format available for downloading.

Abstract: We consider the construction of an internet site for students of technical university. We use the construction and management of the site program JOOMLA. The site can contain the materials for the students, results of an exam and so on.

Abstract: Virtual research centre of digital preservation in Europe provides a natural basis for long-term consolidation of digital preservation research and expertise. Spatial Data Infrastructure will cover technical methods for preservation, access and most importantly re-use of data holdings over the whole lifecycle; legal and economic issues including costs and governance issues as well as digital rights; and outreach within and outside the consortium to help to create a discipline of data curators with appropriate qualifications. Main tasks of Spatial Data Infrastructure SDI development are building global infrastructure for IT and geodata; satellite information harmonization; usage of agreed upon set of standards; clear documentation describing the parts of the system; interoperability between independently created applications and databases; common standards within their interfaces, protocols and data formats; and finally support of a general data policy for data creation, access, and support of satellite information. Fundamental principle of Russian segment of SDI is providing interoperability – the ability of interaction for heterogeneous services and data catalogues within the bounds of a unified informational system. The Russian segment of distributed informational system has been built on the basis of EOLI-XML and SSE technologies.

Abstract:

The paper addresses the problem of multi-level similarity analysis of Android applications based on static features in digital application collections. Such collections may contain duplicates, forks, repackaged builds, and other modified variants; malicious payloads are treated as a special case of modification rather than as a synonym of repackaging. The paper formulates a similarity function for Android applications, introduces a static application model as the working object of comparison, and presents a multi-level pipeline that separates candidate screening, in-depth pairwise analysis, result interpretation, and a decision layer. Meaningful similarity signals are sought not only in classes.dex bytecode, but also in AndroidManifest.xml, resources, APK-internal metadata, and library dependencies. A numerical similarity score is computed only when static models are built successfully; otherwise the pipeline records a dedicated technical failure status together with a normalized failure reason. Preliminary evidence is reported on a local pilot set of five core pairs and two boundary cases. These results indicate that explicit handling of shared library code may improve interpretability, but they do not yet constitute a full validation of the proposed architecture on large collections.

Under the specifications of data semantics only the datatype properties were used.

Abstract: В работе рассматривается общая архитектура новой версии системы ИСИР, опирающейся на открытые стандарты W3C: Semantic Web [SW], XML[XML] технологии, и на применение opensource решений. Архитектура позволяет разрабатывать распределённые объектно-ориентированные информационные системы - цифровые библиотеки, информационные и корпоративные порталы, сайты на базе различных типов хранилищ информации, таких как объектные и реляционные базы данных, LDAP-каталоги. Система параметризуется описанием объектной схемы данных конкретной предметной области и легко адаптируется к её изменениям. Для описания схемы используется W3C стандарт на описание схем Интернет ресурсов - RDFS. Архитектура имеет многоуровневую модульную организацию, каждый уровень имеет собственные цели и абстракции. Фундамент решения - ядро ИСИР - унифицирует механизмы работы с хранимыми объектными данными, предоставляет ряд услуг по управлению этими данными, например, разграничение прав доступа, журнализация изменений. На базе ядра строятся более высокоуровневые сервисы такие, как RDF/XML-обмен данными, репликация информации между репозиториями, атрибутно - полнотекстовая индексация данных и др. Имеются средства для простой и эффективной разработки пользовательских Web-интерфейсов. Средства публикации информации и построения отчётов применяют механизмы XSLT и поддерживают широкий спектр целевых форматов. Служба управления потоками работ по редактированию ресурсов репозиториев следует стандартам WfMC - канонической модели и языку спецификации потоков работ XPDL. Служба управления содержанием Web-сайта обеспечивает мульти - иерархическую каталогизацию слабоструктурированной информации, отличающейся нерегулярностью взаимосвязи ее элементов.

Algorithms for creating a meta description of retro collections based on the analysis of the structure of mathematical documents and the use of software tools for extracting metadata are given. The description of retro-collections formed using the developed algorithms and included in the metadata factory of the digital mathematical library Lobachevskii-DML is given. The schemes for the formation of metadata and methods for normalizing the extracted metadata in accordance with the schemes and requirements of the integrating mathematical libraries are indicated.

Abstract:

This paper examines the development of the SciLibRu library of scientific subject areas, as a continuation of the semantic description of scientific works from the library LibMeta project. This library is based on a conceptual data model, the structure and semantics of which are formed based on the principles of ontological modeling. This approach ensures a strict description of the subject area, formalization of the relationships between entities, and the possibility of further automated data analysis. The goal of the study is to develop and experimentally apply methods for structuring scientific journal data in LaTeX format for their integration into the library ontology and to support semantic search.

An algorithm for translating data represented by multiple files into XML format is proposed for integration into the library ontology. A vector search module based on embedding calculation using language models is implemented. Patterns in the distribution of embeddings and factors influencing the accuracy of search results ranking are identified. Testing of the two components is conducted.

The developed method forms the basis for automatically incorporating scientific journal data into the SciLibRu knowledge graph and creating training corpora for language models limited to scientific subject areas. The obtained results contribute to the development of journal knowledge graph navigation systems, recommendation engines, and intelligent search tools for Russian-language scientific texts.
