Despite the fact that data catalogues are widely used in different areas, data search that is considered as thema-jor part of data systematization, is being done with strictly formulated search requests that result in a search results list. How-ever, quite often it is impossible to state a specific search request. It is also impossible to state search criteria specifically. To avoid restricting the access to full information in givencatalogues, it is recommended to provide quality system access. The article addresses software solutions for systematization of heterogeneous data. The article gives solutions description in words and parameters to provide forming a ranked search results list that matches a search request best. The article proves motivation for the use of basic principles of fuzzy systems principles when selecting solutions in registers and catalogues. The article describes an algorithm of multistep decision making process for an original problem with a fixed number ofsteps. It also demonstrates how this system works in a data catalogue.

The paper represents the survey of the social network analysis methods. That analysis is used to study the in-teractions between network members, prediction their behavior, classification of the members, modeling information flow in networks. There are four main research areas: structural, resource, regulatory and dynamic. To solve the problems in social network analysis the following methods are used: graph and stochastic models, models of network evolution, methods in-volving ontologies, structural and relational models, machine learning methods, network visualization techniques, etc. This paper provides a brief description of popular computer socialnetworks, various approaches and models used in the network characteristics calculation, and lists the software applications that help automate the process of analysis. Several possible di-rections of further studies in this area are outlined: creation of social networks integrated theory, adaptation ofnatural lan-guage text processing methods to the online content, etc. In order to generalize the behavior of specific members ofthe net-work to the entire network, it is necessary to study methods for the detection and characterization of networks, patterns of distribution of these characteristics, the creation of methods to determine the cause of the participants’ interaction.

25. Social processes modeling and multi-agent approach [№3 за 2013 год]

The purpose of the article is a simplified model of society available for software implementation and based on multi-agent approach. The model includes several agent types, for example, workers,officials, owners etc. In addition, division within one group is possible. For example, workers who extract resources andworkers who process resources. Agents can change their type under certain predetermined conditions. The agent represents not a single individual but a group of people. Each agent is described by a set of properties and attributes. Properties include geographical situation, abilityto do cer-tain actions etc. An attribute is certain measurable variable (scale). Agent’s behavior depends on attributes’ value. Basic set of attributes is common to all types of agents but depends on agent’s type attribute can be in active or passive mode. Agents influence and interact with each other. Ways to influence depend on agents’ types. There are some base ways to interact. First, through changing attributes, for example, agent-officials collect taxes from agent-workers reducingthe level of their fund attribute. Second, through operations directive, for example, an agent-owner can send its subordinateworkers to a new location or give them a new job. Agent’s goal is to improve its attributes.

The article considers perspectives on electronic learningdevelopment, such as massive open online courses (MOOC), educational processes gamification and socialization, creating simulators, using augmented reality and mobilede-vices. Special attention is paid to the problem of education material formation for using in electronic education. Expediency of school sites creation is designated. The concept of using LMS and LCMS, standards and specifications for training sys-tems creation are also considered. Nowadays the tendency ofcreating space simulator centers and using innovative educa-tional technologies there can become a considerable contribution to development of youth training programs. First space simulator centers working experience has shown that they canhelp to get additional academic training on astronautics bases, control systems of manned spacecrafts. Preparation and presentation of educational and methodical material versions have to meet the requirements allowing using possibilities of software and hardware complex effectively. These requirements can in-clude an order of material formation, representations using modern visualization tools and variants of learning and progress monitoring. Uniting electronic leaning progressive ideas in the context of educational space centers development can also be an approbation of new ideas for future reference in operators training systems on difficult objects and processes management.
