Computer-aided sociological data-analysis tools that form the basis of modern empirical sociological surveys are considered. The tools include methods of statistical analysis and tools for computer-aided support of scientific studies and intelligent data analysis.

A rationale is provided for the importance of assessing the availability, volumes, and relevance of scientific and technical information (STI) on content-aggregator websites. It is suggested that STI be classified into two groups: scientific information and engineering/technical information. Based on certain categorization principles described in this article, content-aggregator websites are divided into 33 categories. A discussion is given of the possibilities and drawbacks of the webometrics methodology that is used in Russia to evaluate websites with scientific content. A new methodology is proposed for evaluating the volumes and relevance of information on aggregator websites of scientific content. The proposed methodology has been tested on the websites of several leading foreign and Russian organizations aggregating multithematic scientific information. A discussion is given about the place of these websites in the global and Russian scientific infospace, the composition and sources of the scientific information aggregated on the websites, the terms of access to this information, and whether and how these websites use systems for calculating scientometric indicators. The webometric indicators are presented and discussed for all the websites included in the study.

This paper addresses the problem of designing an attribute-based search subsystem when integrating an identity management (IDM) system with modern complex systems (e.g., enterprise resource planning (ERP) systems) that have granular access control. When implementing integration solutions with a large number of roles and users, the context search preset in IDM systems proves to be inadequate. We propose and implement a solution to this problem that consists in changing the approach to the organization of a role search and description and present an approach to determining the optimal number of attributes required for an efficient search.

The project elaboration of the configuration and mathematical model of distributed blockchain data storage, blockchain applications for implementing various information technologies, and blockchain requirements that stem from its analytical and structural features are considered.
