The user activity for finding informative meaningful objects needed to solve the problem is considered. To formalize this activity, set theory is used. The mathematical models of formulation of request, analysis of the issued documents and selection of information objects for the solution to the user problem are presented. In addition, mathematical models of intellectual activitiesof user and cognitive processes are developed. The experimental results of the search engines such as Google, Yandex, META, Rambler, Yahoo are given.
This paper describes the models and methods, the use of which can solve the problem of synthesis of architecture description of information system. The method of synthesis of options of architecture description of information system was developed. A game-theoretical model describing the synthesis of rational architecture describe of information system. Features of using synthesized description to determine project constraints are described.
The structural model of information integration data about the software UI elements (different graphic representations, properties and parameters, and multi source code implementation in various programming languages, etc.) with the structural modules of tracking and storing data about interactions of user interface is proposed.
In this article genetic algorithms are considered including their types and practical applications. The scientific works of domestic and foreign researchers have been studied. This article presents methods and examples of solving tasks of data mining for genetic algorithms. The description of main components of models of genetic algorithms is presented. A parallel between biological systems and systems aimed at solving technical problems is drawn. The review and analysis of approaches to modeling of information processes with the use of genetic algorithms is carried out.
The article studies modern legal and scientific approaches to the analysis of the category “information system” as the object of legal protection in the information society. It indicates that in the legislation there is a significant number of legal acts containing definitions of “information system”. These definitions are not identical, which generates some legal conflicts and gives ground to assert the need for appropriate categorical apparatus. The article provides classification of information systems according to various criteria.
The question of media types and their use in proceedings in cases of administrative offenses. The problems of application in Ukraine varieties of media in proceedings in cases of administrative offenses. The ways of solving them.
The paper presents the main approaches to distributed organization of data in computer networks processing and organization of distributed applications. The main approaches to organization of distributed computing systems are described. The conception of GRID computing and comparative analysis of technologies and architectures of "cloud computing" and GRID systems creation are outlined. The estimations of the advantages and disadvantages of computing processes in web-systems are presented. The analysis of analytical models of cloud computing nodes is made.
This article describes the methods of structure creation of geographic information systems and modern requirements for the design of their structure.
This paper is devoted to the overview of current state information support of the functioning for the tourism industry. A structuring of information technologies carried out, identified unresolved problems and proposed solutions.
In the article describes methods of collecting, analyzing and processing of information in the case of energy supply. The systems analysis of the subject area and the conceptual model of the database and structure information support.
