Abstract:

The results on the creation of methods for managing mathematical knowledge in the context of digital mathematical libraries are presented. The software tools developed on the basis of these methods are part of the OntoMath digital ecosystem, within which they interact. A brief description of the architecture of the OntoMath ecosystem is given, the levels of subject ontologies and external ontologies are highlighted, as well as the level of software tools and services. Semantic services are separated into a separate category. This term denotes software tools, in the functionality of which queries to subject ontologies are used to ensure the management of knowledge objects. General descriptions of developed subject ontologies are given: educational mathematical ontology OntoMath^Edu and ontology of professional mathematics OntoMath^PRO. The development of educational ontology is reflected in the direction of including educational prerequisite links between classes. Among the software tools of the digital ecosystem, search services for mathematical electronic collections, a service for semantic annotation of mathematical documents, tools for semantic marking of educational mathematical documents, as well as a system for automatically generating testing tests in mathematical educational disciplines are highlighted. As part of the OntoMath digital ecosystem, special-purpose recommender systems are being developed. The current version of the ecosystem includes a recommender system for generating a list of related articles based on the OntoMath^PRO ontology, a recommender system for appointing experts to support the scientific review process, and recommender systems for selecting subject classifiers UDC and Mathematics Subject Classification codes for mathematical documents. The results are also presented in the direction of creating a digital library metadata factory, which includes services and tools for extracting, refining, replenishing and normalizing the metadata of electronic mathematical collections. Note that the OntoMath ecosystem is being developed as the technological basis for the Lobachevskii Digital Mathematical Library.

Abstract: We describe hereby the methodology and technology for creating of the multi-purposed information environment ‘T System’ based on the extension of the digital library T-Libra. The environment is destined for the integration of resources and services, which a typical for digital library with flexible full-text search, virtual museum, digital archive, research laboratory and educational server. The methodological basis this sort of extension is a hybrid two-level ontology based on interaction of functional systems (top level), concepts library and thesauri library (lower level). The technological basis of extension is an administrative division, which has tools for flexible set-up of T-System’s, as well as an unified search system includes the mechanisms of nonlinear cascade inquiries, which of that generate a relevant functional systems and combine the results of full-text search, related thesauri and concepts, text metadata and non-text objects of different modalities (graphics, sound, video etc.). The above-mentioned environment is designed in three-tier architecture (Web-browser / Web-server + Application server / DB server) with using of special indexing system for increase of search effectiveness, as well as of external logic which is built-up in Application Server.

Abstract:

This paper presents a digital platform for complex monitoring data of dangerous geodynamic, engineering-geological and hydrogeological processes occurring in the region of intensive nature management of the central ecological zone of the Baikal natural territory (CEZ BNT). The platform is intended for integration and analysis of data coming from several polygons located within the CEZ BPT in order to assess the state of the geological environment and forecasting of hazardous processes manifestation.

The platform is built on a client-server architecture. Storage, processing and analysis of data is carried out on the server, which users can access via the Internet using a web browser. Several data filtering methods (linear frequency, Savitsky-Goley and others), various methods of spectral and wavelet analysis, multifractal and entropy analysis, and spatial data analysis are currently available. The digital platform has been tested on real data.

Abstract:

The modern information space contains a lot of data, but they are often poorly structured, difficult to find and not always correct. This creates additional difficulties during researches, so digital spaces of scientific knowledge are currently being formed, in particular, based on knowledge graphs.

To ensure the quality of information, such graphs are often filled with data manually, which is time-consuming. Therefore, the creation of a tool that provides the ability to automate process of filling a graph with data, as well as ensures data quality, will simplify and speed up the process of forming digital spaces of scientific knowledge.

Methods for automating the filling of the graph with data are proposed, including parallel control of their integrity. Based on the proposed methods, a software module has been developed, the mechanisms of its functioning and its architecture are described.

Abstract:

The work presents a digital platform for supercomputer modeling the problems of spraying the particles on substrates. The purpose of this work is to discuss the general architecture, technology stack and implementation features of the platform's user interface. The platform is based on web technologies for access and management of calculations, which allow implementing a user system for conducting a full cycle of a computational experiment, including the configuration of applied applications, their launch on remote computing resources, monitoring the completion of tasks, analysis and interactive visualization of results. User interaction with computing resources is implemented through the graphical interface that does not require the client computer to have any additional software, except actual version of a modern web browser. An important advantage of the platform is the ability to make large-scale computer research in a multi-user mode that is based on the natural principles of building client-server applications. The presented digital web platform was successfully tested on computing clusters of the KIAM RAS in solving a number of the topical mathematical problems of nanotechnology. Also, with its help, for the last 3 years, group training of MIPT students in modern information technologies has been carried out.

Abstract: Combined electronic submission allows the reader to use both graphical representation of pages of printed publications and a full set of textual information. Various issues of support for this view in the Digital library are discussed in this article. The proposed solutions are used both in the technology for information preparation and the architecture of digital library server.

Abstract: We investigated the current models of the publication and dissemination of scientific knowledge. We also presented different approaches to the organization of the personal information space of scientist. We describe the modern information management system of scientific publications and services that determine their functionality. We have created software modules for automating of electronic scientific journal workflow. These modules are an extension of Open Journal Systems. We describe the architecture of a universal information management system of electronic scientific journals and management platform of “Russian Digital Libraries Journal”.

Abstract: The issues of development of intersubject communications at the present stage of the formation of digital education in the preparation of student architects are discussed. The idea of strengthening intersubject communications, mathematics and architecture is defended by a new meaningful replenishment of educational programs, mastering digitalization skills when solving mathematical problems by mathematical methods, and involving elements of competition implemented using Web technologies in educational activities.

Abstract: There are policy, technical, and workflow gaps in library efforts to preserve online journal literature. Since libraries are increasingly involved in journal publishing, HathiTrust, a shared preservation-quality digital repository, is a natural place to archive and provide access to journal literature to ensure its long-term preservation and discoverability. The University of Michigan Library is funding the creation of mPach, an open-source, end-to-end publishing system in which archiving in HathiTrust happens as a byproduct of publication rather than being carried out after the fact. The architecture of mPach, its envisioned workflow, and plans for creating a shared infrastructure for publishing open-access journals are all summarized.

Abstract:

Cloud platforms and services have become an important factor in the explosive development of the digital economy in the last decade. The ability to quickly scale the service, coupled with a reduction in investment costs at the start of projects within the framework of the Iaas, PaaS, SaaS approaches, gave positive results and formed the basis of new business models and corporate solutions.

 

In this article, we discuss the reasons for the importance of multicloud and explore approaches to integrating cloud services in a multicloud architecture. The article also proposes a way to solve the problem of cloud migration - developing a system for migrating cloud resources between cloud services.
