Документ Business data processing based on algebra-logical models(Харківський національний університет Повітряних Сил ім. Івана Кожедуба, 2017) Cherednichenko, Olga Yurevna; Gontar, Yulia Mukolaivna; Vasylenko, Artem Viktorovich; Matvieiev, O.Issues of business information processing, which are necessary for management decision- making, are considered in the article. Algebraic-logical models, which allows to process heterogeneous information obtained from various sources are presented. In the case study the reference model of business information processing on the stage of project plan elaboration is presented. Correspondence between an artifact and associated with it requirement is performed by comparator identification.Документ Forecasting the results of football matches on the Internet based information(НТУ "ХПИ", 2017) Klyuchka, Yaroslav Aleksandrovich; Cherednichenko, Olga Yurevna; Vasylenko, Artem Viktorovich; Yakovleva, Olena VladimirovnaThe purpose of the article is making a model of results forecasting for football matches, which works better than bookmakers organizations. Lately the popularity of football forecasting has been increased. The existing statistic approaches show difficult and low prediction. The developed model for predicting the results of football matches uses information about the previous results of the teams. The forecast is based on forecasting factors. Although it is difficult to consider all the factors that influence the results of matches the model makes an attempt to find the most important ones. The described model of forecasting takes into consideration such characteristics as: place in the tournament table; total points; goal difference; total number of players, skipping the match; points home / away; home match; "defence strength"; "attack strength"; team form. Testing shows that forecasting and actual results of football matches coincide. The offered model could be used in commercial computer programs for forecasting results of football matches in bookmakers organizations.Документ Towards information system development for data extraction from web(НТУ "ХПІ", 2018) Gontar, Yulia Mukolaivna; Tkach, Kateryna Victorivna; Yena, Bohdan Oleksandrovych; Vasylenko, Artem ViktorovichToday, the Internet contains a huge number of sources of information, which is constantly used in our daily lives. It often happens that similar in meaning information is presented in different forms on different resources (for example, electronic libraries, online stores, news sites and etc.). In this paper, we analyze the extraction of information from certain type of web sources that is required by the user. The analysis of the data extraction problem was carried out. When considering the main approaches to data extraction, the strengths and weaknesses of each were identified. The main aspects of the extraction of web knowledge were formulated. Approaches and information technologies for solving problems of syntactic analysis based on existing information systems are analyzed. Based on the analysis, the task of developing models and software components for extracting data from certain types of web resources were solving. A conceptual model of extracting data was developed taking into account web space as an external data source. A requirements specification for the software component was created, which will allow to continue working on the project and to clearly understand the requirements and constraints for implementation. During the process of modeling software, the following diagrams have been developed, such as activities, sequences and deployments, which will then be used to create the finished software application. For further development of the software, a programming platform and types of testing (load and modular) were defined. The obtained results allow to state that the proposed design solution, which will be implemented as a prototype of the software system, can perform the task of extracting data from different sources on the basis of a single semantic template.
