    Methods of information resources processing in virtual library
    (Lviv Polytechnic National University, 2018-06-25) Rusyn, Bohdan; Vysotska, Victoria; Pohreliuk, Liubomyr; Kazimierz Pulaski University of Technology and Humanities in Radom, Poland; Lviv Polytechnic National University, Lviv, Ukraine; Karpenko Physico-Mechanical Institute of the NAS Ukraine
    The thesis discusses the development of unified methods and software tools for processing information resources in Virtual Library as example the electronic content commerce systems (ECCS). A model of Virtual Library Systems (VLS) is proposed. The models of information resource processing in ECCS are proposed. Architecture and models of VLS are built. A new approach to application and implementation of business processes is formulated for the construction of VLS. A complex method of content creation, the operational method of content management and complex method of content support are developed. Design and implementation methods of VLS are based on online newspapers, which reflect the results of theoretical research, are developed. From the perspective of a systemic approach, the principles of applying information resources processing in electronic content commerce systems for content lifecycle implementation made the development of methods for the content formation, management and support possible. An integrated method of content formation for the time and resources reduction of content production is developed. A method of content management for the time and resources reduction of content sales was created, which makes it possible to implement content management subsystem. A method of content support for the time and resource reduction of the target audience analysis in VLS is implemented, which makes it possible to develop a content support subsystem.

    Ontology using for decision making in a competitive environment
    (Lviv Polytechnic National University, 2018-06-25) Lytvyn, Vasyl; Oborska, Oksana; Vysotska, Victoria; Dosyn, Dmytro; Demchuk, Andriy; Lviv Polytechnic National University, Lviv, Ukraine; Silesian University of Technologyty, Gliwice, Poland; Karpenko Physico-Mechanical Institute of the NAS Ukraine
    A method of decision making system elaboration in competitive environment based on ontological approach was developed. The models based on a hinged Boyd-Moore automaton. State machine loops are the stages Boyd and filling processes, ontology editing and a search of relevant knowledge ontology. Possible transitions between the states of the machine and transfer parameters between them were determined. For a quantitative modeling of decision support process in a competitive environment, mathematical support and methods of domain-specific ontology in the Boyd cycle (OODA – observation, orientation, decision, action) were elaborated. Thus, for the military at an “Observations” stage intelligence domain ontology determining of the strengths and weaknesses of the enemy. At the stage of “orientation”, ontological data are used for simulation of possible realizations of the battle and for optimal positioning of the forces. For “Resolution” stage, target distribution was developed using a method based on genetic algorithms, which helped to reduce the computational complexity of finding effective distribution targets. Ontology expertise based on descriptive logic is presented to increase the effectiveness of possible solutions.

    The information system for identification of content set based on analysis of similar texts
    (Lviv Polytechnic National University, 2018-06-25) Kovalchuk, Viktoriia; Lytvyn, Vasyl; Vysotska, Victoria; Hrendus, Mariya; Naum, Oleh; Lviv Polytechnic National University, Lviv, Ukraine; Silesian University of Technologyty, Gliwice, Poland; Drohobych Ivan Franko State Pedagogical University, Drohobych, Ukraine
    Information search is one of the most dynamic areas in terms of development and search for new algorithms for solving this problem. Nowadays a large number of search engines, which work with artistic composition, have been developed, but most of them are oriented only on conducting the work with metadata. In addition, effective methods of analysis of the subject of the text have been used, as well as identification of works after it is considered. Different ways of searching and problems of implementation of an ontologically flexible semantic search are considered. An information system for the identification of a plurality of content has been developed based on a thematic analysis of similar texts.

    Content analysis of Text-based information in E-commerce systems
    (Lviv Polytechnic National University, 2018-06-25) Lytvyn, Vasyl; Vysotska, Victoria; Chyrun, Lyubomyr; Hrendus, Mariya; Naum, Oleh; Lviv Polytechnic National University, Lviv, Ukraine; Silesian University of Technologyty, Gliwice, Poland; Drohobych Ivan Franko State Pedagogical University, Drohobych, Ukraine
    Instrumental means, information technologies and software for constructing such systems have been analyzed and summarized in the article based on the analysis of the basic tasks of electronic content commerce system (ECCS). ECCS functional diagram with information resources processing subsystems has been developed. The overall architecture, objectives and principles of ECCS realization were described in details. The functional elements of the system were described according to GOST 24.204.80, GOST 24.201-79, GOST 19.201-78, GOST 34.602-89, IEEE Std 1233, 1998 Edition, IEEE Std 830-1998. Software creation tools as well as management and maintenance of content were developed. The software realizations of developed ECCSs with resources processing subsystems to set up e-commerce in online newspapers and online journals were presented.

    A method of construction of automated basic ontology
    (National Technical University «KhPI», 2017) Lytvyn, Vasyl; Vysotska, Victoria; Wojcik, Waldemar; Dosyn, Dmytro; Lviv Polytechnic National University; Institute of Electronics and Information Technology, Lublin University of Technology; Systems Analysis Laboratory, Karpenko Physico-Mechanical Institute of the NAS of Ukraine
    The paper describes an approach to development of a computer system that automatically constructs an ontology base. Basic modules of the system and its operation are described, as well as the choice of software tools for implementation. Application of the proposed system allows to fill the domain ontology in an automatic mode. Therefore, this paper introduces an approach to development of an automated basic ontology composition. An architecture of synthesis of the ontology system is created using CROCUS (Cognition Relations or Concepts Using Semantics) software model. The main system modules and their functions are described. A decision of SDK for system realization is justified. Application of the proposed system can fill an ontology of subject area automatically.

    Intelligent system structure for Web resources processing and analysis
    (National Technical University «KhPI», 2017) Lytvyn, Vasyl; Vysotska, Victoria; Chyrun, Lyubomyr; Smolarz, Andrzej; Naum, Oleh; Lviv Polytechnic National University; Institute of Electronics and Information Technology, Lublin University of Technology; Information Systems and Technologies Department, Drohobych Ivan Franko State Pedagogical University
    The paper describes the general detailed and formal description of intelligent system of information resources processing (ISIRP) based ontology. The content life cycle phase implementation of ISIRP structure is improved. The general principles of ISIRP designing structures enable automated information resource processing to increase regular user text content realization, reducing the production cycle, saving time and increasing the e-commerce capabilities.
