Spreadsheets are an important source of information and can be used to create domain models and knowledge bases. We implement an approach for transforming spreadsheets into domain models. This approach consists of 4 steps and based on the use of: an intermediate unified representation of spreadsheets in a canonicalized form, an original technique and software. A canonicalized form provides processing spreadsheets with arbitrary layouts and styles. The original technique provides a two-stage transformation: source spreadsheets to canonicalized tables and canonicalized tables to domain model fragments. Original software is presented by two tools: TabbyXL as a table transformation tool and Personal Knowledge Base Designer as a knowledge base prototyping tool. We present an experimental evaluation of the proposed approach for generating domain models. Two datasets are used for our experiment: Troy200 and ISI-161. We obtained high values of recall and precision (more than 90%) for both datasets. At the same time, the content of resulted domain model fragments was evaluated for the ISI161 dataset. This evaluation showed that 24% of concepts of the domain model for industrial safety inspection tasks were generated automatically by using our approach.

This study demonstrates a comparative analysis of surface and satellite measurements. The average concentrations of PM2.5 and CO, SO2, measured at the Listvyanka station located on the coast of Lake Baikal, were considered. Satellite measurements data (Copernicus Sentinel-5P) were recomputed based on the SILAM model. A joint analysis of data showed that satellite measurements were suitable for a spatial description of regional air pollution. The computed maxima coincided with the surface measurements in terms of time periods and general monitoring results. However, at extreme increases in concentrations of pollutants, a significant difference in the numerical values was registered. Satellite monitoring data confirmed the relationship between the increase in PM2.5 and CO concentrations in the air basin at the Listvyanka station and the transfer of smoke plumes from intense forest fires located at a distance of 1, 500-2, 000 km. © 2022 SPIE.

3rd Scientific-Practical Workshop Information Technologies: Algorithms, Models, systems, ITAMS 2020

作者： Shigarov, Alexey Khristyuk, Vasiliy Cherkashin, Evgeniy Yang, Shuo Matrosov Institute for System Dynamics and Control Theory of SB RAS 134 Lermontov st. Irkutsk664033 Russia School of Computer Science and Cyber Engineering Guangzhou University 230 Wai Huan Xi Road Guangzhou510006 China

This addresses representation of the table semantics for the cross-context information exchange. The tables we consider have an arbitrary cells structure represented in a machine-readable format. For example, tables can be contained in electronic documents, such as a spreadsheet or a web-page, and, typically, they are not accompanied by semantics enabling their automatic interpretation. In spite of the existing variety of formalisms for representation of the table semantics, most of them they are fairly inefficient in terms of the user efforts required for the semantic annotation. We outline a new approach to the lightweight representation of the table semantics. We stay on the interpretation level that provides the inference of the semantics of atomic data items of a table from a description of data groups expressed by the syntax of the table. We expect that, in the future, implementation of our approach can reduce the complexity and volume of the table semantics required for the cross-context information exchange, as well as the user efforts aimed at annotating tabular data. © 2020 for this paper by its authors.

Superparticle in an external chiral matter superfield

arXiv 2022年

作者： Adolfovich, Yuri Markov Markova, M.A. Bondarenko, A.I. Markov, N.Yu. Matrosov Institute for System Dynamics and Control Theory Siberian Branch Russian Academy of Sciences Irkutsk664033 Russia

In this paper the interaction Lagrangian of a superparticle with an external chiral (mattеr) superfield Ф(x,θ , θ ), invariant with respect to the global supersymmetry, is proposed. The kinematics of the superparticle is defined in an extended superspace described by superspace coordinates (xμ ,θα ,θα ), where xμ are pure bosonic coordinates, μ = 0,…, 3;θα and θα are additional fermionic Grassmann-valued spinors. With the purpose of the construction of the required Lagrangian, the chiral analogues of the supervector Aμ(x, θ, θ¯) and superspinor Aα(x, θ, θ), Aα (x, θ, θ) gauge fields are introduced, which are also matrices in color space. The problem considered in this paper is the further step in deriving the dynamical equations of motion for a spin color-charged particle moving in an external fermionic matter field. These equations of motion are of fundamental importance, for example, when taking into account the influence of fermionic background fields induced in a hot quark-gluon plasma (QGP) by thermal fluctuations on the dynamics of hard color-charged partons crossing the QGP. In turn, the solution of this problem will make it possible, at least at the qualitative level, to advance in the study of the motion in the external fermion matter field of such a complex physical object as a string. © 2022, CC BY.

The paper presents the architecture of the information system to support archaeological research of the AIS "Geoarcheology". The system provides registration, accounting and analysis of various archaeological data at all stages of research. The system consists of a set of related subsystems focused on solving individual problems of archeology. For example, carrying out excavation work, photographing, accounting for publications and reports, dating results, collecting and presenting spatial data. The technology and the GeoARM tool are used to automate the creation of the AIS "Geoarcheology". This approach provides automation of the development of application systems through the application of declarative specifications. Using this technology allows you to quickly expand the list of indicators without recompiling the system, which is important in the context of emerging standards of archaeological research.

Tables are widely used in organizing, presenting, and storing data. However, as a rule, they have different arbitrary layouts and are not accompanied by explicit semantics necessary for machine interpretation of their content. Recent research has shown great progress in solving various problems in the field of automatic table understanding. Despite this, there is still a need to develop more effective solutions that are applicable in practice and take into account data with different linguistic backgrounds. In this paper, we propose a new RuTaBERT framework based on a pre-trained language model and provide semantic column annotation of Russian-language tables. We used a preprocessed large-scale corpus of Russian-language web tables extracted from Wikipedia pages as training data to fine-tune the language model. The experimental results obtained show the prospect of using the proposed framework, including when solving applied problems.

The light-by-light contribution from the lightest neutral pseudoscalar mesons to the anomalous magnetic moment of muon is calculated in the framework nonlocal SU(3) × SU(3) quark model. The model is based on four-quark interaction of the Nambu-Jona-Lasinio type and t'Hooft six-quark interaction. Full kinematic dependencies of vertices with off-shell mesons in the light-by-light scattering amplitude is taken into account. As a result of that dependence the pseudoscalar contribution aμPS,LbL=(5.85±0.87){dot operator}10-10 is smaller then most of previous estimates. The comparison with the results of other models is performed. © 2011 Elsevier B.V.
