Документ Item Matching Based on Collection and Processing Customer Perception of Images(2020) Cherednichenko, Olga; Vovk, Maryna; Ivashchenko, OksanaThe number of sellers and goods being sold on the e-marketplaces is growing, so the volume of data stored and processed by e-commerce information systems is increasing drastically. That is why the development of performance solutions is quite relevant. The given paper provides the approach of item matching based on the human perception of item images. The main goal of the study is to build a model for assessing the similarity of items. This paper provides a description of a software product for comparing product images collected on online trading platforms. The user evaluates the product visually. The developed software implements the crowdsourcing data collecting based on the comparator identification method. The use of this method involves an experiment in which the user is offered two images, by comparing which the determined binary reaction is obtained. The results show the perspective of the mobile client application as part of an item matching system that aims to optimize the search for products on the Internet.Документ Modern problems of computer science and IT-education(Premier Publishing s.r.o., Vienna, Austria, 2020) Aleksiyev, Volodymyr; Bilova, Mariia; Borysova, Natalia; Cherednichenko, Olga; Fedorchenko, Volodymyr; Goloskokov, Alexander; Goloskokova, Anna; Harasymchuk, Oleh; Havrylova, Alla; Holubnychyi, Dmytro; Ivashchenko, Oksana; Kalachova, Veronika; Kozulia, Mariia; Kozulia, Tatiana; Liutenko, Iryna Victorivna ; Melnyk, Karina; Melnyk, Marharyta; Milov, Oleksandr; Opirskyy, Ivan; Romaschenko, Natalya; Ryabukha, Yurii; Salo, Nataliia; Shmatko, Olexander; Soroka, Mykhailo; Tretiak, Viacheslav; Trystan, Andrii; Vlasov, Andrii; Vovk, Maryna; Yanholenko, Olha; Yevseiev, S. P.The collective monograph highlights modern problems of development and using information technologies for resolving some issues in different domain areas. The proposed theoretical methodologies, models and practical approaches are considered and investigated in the context of IT-education, software engineering, artificial intelligence and cybersecurity. Every chapter describes methods, efficient algorithms and resolutions specific for the particular domain area and field of knowledge.Документ Opportunities for sustainable mobility promotion among students of the University of Maribor, Faculty of Organizational Sciences(University of Maribor, Slovenia, 2020) Senegacnik, Marjan; Baggia, Alenka; Kovacic, Branka Jarc; Vovk, Maryna; Cherednichenko, OlgaThe aim of sustainable mobility is to choose means of transport that have the least possible impact on the environment. Since all motor vehicles cause a direct or indirect form of pollution, walking and cycling are an ideal form of mobility from an environmental point of view. If the use of vehicles is taken into account, public transport generates much less pollution per passenger than the car. In addition to logistical problems such as congestion and lack of parking space, the massive use of cars is a major contributory factor to a sharp deterioration in air quality in urban areas and causes emissions of greenhouse gasses. In addition to promoting sustainable forms of mobility, rational route planning is also important. It is, therefore, reasonable to prepare the timetable of activities, stressing the importance of limiting unnecessary routes. In this paper, we will see how sustainable mobility can be addressed in a higher academic environment. Several proposals are presented to optimize mobility by rationalizing the organization of students' obligations within the faculty.Документ Towards Structuring of Electronic Marketplaces Contents: Items Normalization Technology(2020) Cherednichenko, Olga; Yanholenko, Olha; Vovk, Maryna; Sharonova, NataliiaThe E-commerce industry is going strong and is bringing a great profit to its stakeholders. However, there is probably no buyer of the e-marketplace who has not faced the issues connected with inappropriate search results or inadequate filtering and recommendation of irrelevant products. Modern search and collaborative filtering algorithms of e-commerce systems do work well with the input data of high quality but the reality is that often items’ description contains inaccuracies and incompleteness, which negatively affects the results. The given paper suggests the concept of e-marketplace items normalization which goal is to provide the unified and standardized patterns of items inside the system that can be used by search and filtering algorithms. Items normalization is implemented based on the algebra of predicates models specified in this work. The case study deals with constructing normalized models of knapsacks items from the online sports store. The developed models allowed to build 141 normalized item patterns with a unified set of attributes and their values.
