Представляем работы Виктора Чумачева
Виктор Чумачев – известный московский художник, который сотрудничает с «Системным администратором» уже несколько лет. Именно его забавные и воздушные, как ИТ, иллюстрации украшают многие серьезные статьи в журнале. Работы Виктора Чумачева хорошо знакомы читателям в России («Комсомольская правда», «Известия», «Московские новости», Коммерсант и др.) и за рубежом (США, Германия). Каждый раз, получая новый рисунок Виктора, мы в редакции улыбаемся. А улыбка, как известно, смягчает душу. Поэтому смотрите на его рисунки – и пусть у вас будет хорошее настроение!

Big Data in economic research: sources of information, fields of analysis and required competences

Karasev Oleg, PhD, Acting Head of Statistics Department, faculty of economics of The Lomonosov Moscow State University, assitent professor

Matyuhina Irina, Statistics Department, faculty of economics of The Lomonosov Moscow State University, assitent professor

Legchakov K.E., international business chief expert in a russian state-own company, postgraduate on faculty of economics at the Lomonosov Moscow State University, Kliml@mail.ru.

Petrov Ivan, Graduate from faculty of geology and faculty of higher mathimatics and cybernetics of The Lomonosov Moscow State University, Gazprom Inform Ltd.

Summary

Revolutionary changes at the information sphere conditioned by quantity of intellectual devices, number of internet users, volume and speed of data transaction in broadband channels growth, open new opportunities in different areas of human activities. Economic research is not an exception. As generally known, it requires significant amount of data of different nature contained in various sources to ensure the high quality of analysis. The informational boom foreseen by leading IT-experts in the next 4-5 years will expand frameworks of scientific activities. Statistics and statistical practice due to its objects – mass phenomena and processes in socio-economic sphere – will gain a powerful urge.

There are such methods as bibliometric and patent analysis, web-scraping, social networks analysis, which are now applied in the analytical practice. Quantitative indicators of scientific activities based on these methods are under intent attention in leading countries when forming scientific policies. These approaches are also widely used as tools of S&T and innovation development forecast.

Big data analysis as a part of economic research gives an opportunity to consider systematically an amount of economic agents’ opinions fixed in primary sources, ensuring such a degree of completeness and detail, which could not be reached by traditional expert procedures. Thus, this approach has some drawbacks. Its effectiveness considerably depends on primary data quality. In addition, large-scale English language databases do not fully reflect S&T development of countries speaking other languages. The analysis results depend on the quality of search queries to the database and can vary when changing them. Each of these methods describes the state and prospects of S&T development from different views, and being applied in isolation from other approaches, it creates a false confidence in the correctness of the results and contributes to the linear perception of changes.

The correct application of modern research methods requires appropriate competencies of graduates of economic specialties that need to be developed through educational programs.

The article gives a brief review of modern methods of Big data analysis. The urgent demand of the Russian labour market for specialists with skills of working with Big data as a factor of information society development is proved.

Keywords: information society, Big data, methods of big data analysis.

Programm of analysis and assessment of the effectiveness of leasing operations «LeasingMaster»

Nataliya Kazakova, Plekhanov Russian University of Economics, Professor, Doctor of Economic Science, Head of the Business Analysis Department

Irina Dun, Plekhanov Russian University of Economics, PhD, Associate Professor of the Business Analysis Department

Summary

The economic situation requires to keep under control the company's resources and optimize costs. In the face of increasing competition, both from Russian and from the international business company, especially the production sector, need to constantly update technology, equipment and other fixed assets. However, many Russian companies do not have the opportunity to make a large capital expenditure on the purchase of expensive fixed assets, so these companies use cheaper than buying equipment a method of forming fixed assets – leasing. Compared with the existing software, the program «LeasingMaster» allows not only to calculate the amount of lease payments and expenses under leasing contracts, but also to provide all the necessary information on the leasing transactions, which could be useful for users, including, very importantly, to analyze the efficiency of different leasing schemes to select the most appropriate for a particular company.

Summary

When solving systems of linear algebraic equations with modern, hybrid (CPU GPU) clusters to the user, there arises the problem of selecting values of a number of parameters that have a significant, but unobvious subjection on computing performance and, as a consequence, on time, and, therefore, and technical resources for the solution of the problem. The existing recommendations on the selection of values for these parameters are evaluatives and do not guarantee the best performance computing for a given dimension of the system of linear algebraic equations. The purpose of this work is experimental research of the subjection of the values of the parameters Nb and CUDA_DGEMM_SPLIT LINPACK benchmark, representing a solution of model system of linear algebraic equations by the method of LU decomposition, for the performance computing of hybrid nodes of the cluster «Lomonosov» (Moscow State University, Moscow, Russia Federation). Recommendatory data of the values of the parameters Nb and CUDA_DGEMM_SPLIT LINPACK depending on the dimension of system of linear algebraic equations for achievement of the maximum performance for solving system of linear algebraic equations are obtained by LU decomposition method on hybrid computing nodes of a cluster «Lomonosov». The recommendatory data table constructed in this research work for a cluster «Lomonosov» allows to select unambiguously values of the Nb and CUDA_DGEMM_SPLIT parameters depending on dimension of system of linear algebraic equations for achievement of the maximum computing performance.

Keywords: GPU, cluster, high-performance computing, problem size, hybrid computing node, solving linear systems of equations, GFlops.

Do Multiword Expressions Follow the Zipf’s Law?

Kochetkova N.A., graduate student of the HSE, Department of Computer Engineering MIEM, natalia_k_11@mail.ru

Klyshinsky E.S., PhD., Associate Professor of HSE, Department of Computer Engineering MIEM, eklyshinsky@hse.ru

Ermakov P.D., a graduate student of HSE, Department of Computer Engineering MIEM, permakov@hse.ru

Summary: A dictionary of multiword expressions provides a suitable way for natural language processing. Automatically processing of natural language texts allows shortening the time that we need to construct such dictionaries and enlarge the number of expressions included into a dictionary. In this paper we show that n-gramms of natural language text are following the Zipf’s law; however, the index of power for distribution is varies over wide range. We use this property for such multiword expressions extraction as stylistic markers of a text and special expressions shaping the vocabulary of the selected domain.

Keywords: component design, text analysis, dictionary, Zipf's Law, syntactic patterns, probability distributions.
