Data mining as a cognitive tool: Capabilities and limits

The crisis in the world financial markets, the capitalization of bank profits, the size of which is insufficient to maintain the existing level of the banking system of Kazakhstan, has actualized the quality problem not only in terms of forming credit portfolios of banks, managing banking risks, but also offering high-quality banking services.
Despite the fact that the banking services quality cannot directly affect the financial sphere, the production sphere, and also affect the sharp decline in the economy, the economic losses from poor banking services can significantly increase, causing significant losses to banks. At the same time, it should be considered that the financial losses of the firms as active participants in financial markets are significant in the amount of losses. Consequently, the banking services quality can cause not directly, but indirectly both the success of the banking business and the possible losses of banks. In order to manage the quality of banking services, it is necessary to have certain methods for analyzing and assessing the quality of banking services. This article attempts to solve this issue.
Using various research methods, based on obtaining real assessments of respondents, the present paper presents a methodology for the comprehensive assessment of banking services quality. The developed mechanism includes consolidation of organizational and methodological and economic and statistical methods of research: a five-step SERVQUAL model, integral and general indices, a multiple queue system, instruments of correlation and regression analysis that determine the level of customer satisfaction and problem characteristics of the quality of services offered.

The article considers the relevant problems concerning the correlation between the development of priority economic sectors and sustainable economic growth in Ukraine. The assumption is made that development at the macroeconomic level can only be achieved when the positive dynamics of material production sectors is observed. The resource potential of Ukraine allows to distinguish two main sectors: agriculture and industry.
Many scholars have repeatedly considered ways of achieving positive economic dynamics at the level of the national economy. But despite the existing research on the problems of economic growth, its’ financial assessment and modelling, as well as the dominant factors of influence, remain unsolved. The aim of the article is to identify the factors of economic growth and assess their influence on the overall economic dynamics within two main material production sectors of Ukraine: industry and agriculture. In order to achieve this, the influence factor model of economic growth has been composed, where GDP growth was selected as a result indicator. The choice of influencing factors is substantiated by: quantity of goods and services sold, number of employees in the industry, investments, fixed assets value and the consumer price index. The most influential factors that significantly impact the overall economic dynamics have been revealed in the article.

The implementation of international standards for the bank risk assessment and market risk, in particular, in Ukrainian banking practice is aimed at achieving common standards for regulating banking activities in different countries. This should help to increase the banking sector stability in Ukraine and, accordingly, increase the interest of foreign investors.
The article deals with the methodological approaches to assessing the bank market risk (in particular, SA, IMA and R-SbM approaches) recommended by the Basel Committee on Banking Supervision in terms of standardization and unification of the normative framework of capital requirements for Ukrainian banks. Considering the analysis results, it was determined that the choice and implementation of an optimal approach in the context of Ukrainian banking practice can be carried out in one of two alternative scenarios: 1) a simplified version of a sensitivity based method (R-SbM); and 2) a recalibrated version of the Basel II standardized approach. In this case, the Basel II recalibrated version is more acceptable for use by banks, since it is most relevant to volume and complexity of transactions carried out by Ukrainian banks.
The obtained results are aimed at improving the existing methodology for calculating the adequacy ratio of banks' regulatory capital (N2), which currently considers only the needs for credit risk coverage, and at refining the methodology in terms of considering banks' market-risk coverage needs.
