Development of Web-Oriented Systems: Ontological Approach

The purpose of the article is to study, analyze the possibilities and substantiate the creation of a web-oriented system of a catering establishment (pizzeria) based on the ontological approach, as well as to develop the corresponding software. Achieving the aim of the study involves the following tasks: forming a multi-level ontological model of the subject area (catering establishment – pizzeria) and developing an appropriate web-oriented system on its basis. The research methods are the main methodological approaches and technological tools for web-based systems development based on the use of an appropriate multi-level ontological model. Such methods include, in particular, systemic and comparative analyses (to identify the features of web-oriented systems of catering establishments) and the expert evaluation method (in determining the objects of the subject area and the relations between them). The scientific novelty is the study and analysis of modern technologies for the development of web-oriented systems and multi-level ontological modelling of various subject areas, including catering establishments (e.g., pizzerias), the results of which can be used in the development of their software product – a web-oriented system of a catering establishment. Conclusions. The paper investigates the known views on the modern approach to the development of web-oriented systems based on the implementation of the ontological approach. The proposed ontological model of a catering establishment (pizzeria) is described as a formal specification of knowledge about the selected subject area, its objects and the relationship between them (for a clear and complete representation of the subject area), which plays a significant role at different stages of creating and modifying a web-oriented system. The proposed ontological approach, which involves the development of an appropriate multi-level ontological model, has been used in the design of a web-based system for a restaurant (pizzeria). The use of an ontological model in the development of a web-based system of a catering establishment (pizzeria) helps to reduce the risk of errors in the structure of the system, the component and elemental composition of the system and its information base; more accurate perception of the subject area (catering establishments specializing in different cuisines of the peoples of the world (for example, Ukrainian, Japanese, American, but preferring Italian); use in the model representation of the subject area not only formalized means (formal grammar, descriptive logic, etc.) but also natural languages; making more precise queries to the system’s information base (database and the corresponding knowledge base).

Development of a web-oriented system for the sale of goods using the dropshipping business model

Introduction. Dropshipping is one of the most popular business models used by e-commerce companies. For the operation of the business, the dropshipper provides only an electronic storefront and online customer service. The relevance of the research topic is due to the fact that communication and information technologies create new opportunities for development and optimization of dropshipping business model, contribute to expanding the sales market, improving labor productivity, effective use of resources, and improving the quality of business management and service provision. The purpose of the work is to investigate the theoretical and practical aspects of the dropshipping business model, to build a web-oriented system for the sale of goods based on the dropshipping business model. Methodology. To achieve the goal we applied general scientific methods of analysis and synthesis, logical generalization and comparison, we applied graphical and tabular methods for presentation of research results, we applied functional model IDEF0 and its decomposition to describe business processes of the system for the sale of goods according to the dropshipping business model. Results. The main advantages and disadvantages of the dropshipping business model are given in the article. We discuss options for online sales channels in the dropshipping business model, such as general markets, social media channels, and enterprise own website along with their advantages and disadvantages. The need to develop and implement a web-oriented system for the sale of goods to automate the activities of enterprises in the field of dropshipping is substantiated. At the stage of designing a web-based system for the sale of goods we built model of the business processes of the system for the sale of goods based on the business model of dropshipping in the form of a functional IDEF0 model and its decomposition. We built structural and structural-functional diagrams of a web-oriented system for the sale of goods, a block diagram of the work algorithm. The web-oriented system for selling goods is presented in the form of a catalog – a resource on which all the products offered by the dropshipper are placed in the form of a list with a detailed description of the products. The necessity of using the CRM system as part of the server-end of the web-oriented system for automating the management of relations with customers is substantiated.

English-Ukrainian Parallel Corpus: Prerequisites for Building and Practical Use in Translation Studies

Consistent demand for highly professional translators determines continuous attempts of researchers and programmers to develop and propose reliable tools for both improvement of translation quality and facilitation of translators’ work. Last ten years have brought the parallel and comparable corpora into the focus of Ukrainian scientists’ attention. The aim of the paper is to specify the prerequisites for building the English-Ukrainian parallel corpus and describe its application in Translation Studies. A parallel corpus as a separate type of linguistic corpora cannot be built without alignment that enables placing and extracting corresponding sentences/paragraphs of source and target texts in one space. To create parallel corpora, it is necessary to perform additional text preparation. The Sketch Engine system (an example of a web-oriented system for work with corpora) can offer the solution for annotation with Excel. However, Sketch Engine lacks artificial intelligence techniques for further word processing. There is probability that employment of a neural network in the future will enable text alignment in parallel corpora instead of system users. Data from parallel corpora can be used in translation lexicography, comparative lexico-grammatical works, studies in the theory and practice of translation, language teaching, and development of machine translation systems. Corpus-based translation analysis is extremely relevant to identifying translation solutions that can only be explored on the basis of translation products. It is stipulated by rather frequent absence of dictionary equivalents in most contexts and ready evidence of possible translation variants in parallel corpora that provide the usage of a language unit in a wide range of contexts.

WEB-BASED INFORMATION TECHNOLOGY FOR CLASSIFYING AND INTERPRETING EARLY PNEUMONIA BASED ON FINE-TUNED CONVOLUTIONAL NEURAL NETWORK

There have been rapid development and application of computer methods and information systems in digital medical diagnosis in recent years. However, although computer methods of medical imaging have proven helpful in diagnosing lung disease, for detecting early pneumonia on chest X-rays, the problem of cooperation between professional radiologists and specialists in computer science remains urgent. Thus, to address this issue, we propose information technology that medical professionals can employ to detect pneumonia on chest X-rays and interpret the results of the digital diagnosis. The technology is presented as a web-oriented system with an available and intuitive user interface. The information system contains three primary components: a module for disease prediction based on a classification model, a module responsible for hyperparameter tuning of the model, and a module for interpreting the diagnosis results. In combination, these three modules form a feasible tool to facilitate medical research in radiology. Moreover, a web-based system with a local server allows storing personal patient data on the user's computing device, as all calculations are performed locally.

Application of Fuzzy Logic to Assess Banks' Credit Risk

The banking system is a constantly evolving system. The information environment of the bank is growing, the volumes of processed information are increasing due to the growth of users and banking products. To reduce risks, banks make a financial assessment of the situation of individuals and legal entities. The aim of the work is to develop fuzzy multi-connected models designed to predict the receipt of a positive or negative decision to receive a banking product. The decision is made based on scoring. Scoring consists in assigning points for completing a certain questionnaire developed by underwriters of credit risk assessors. Based on the results of the points gained, the system automatically makes a decision on approving or refusing to issue a loan. Different banks have diffe¬rent scoring models. Purpose of the study. The paper considers the use of fuzzy models for making a decision by a bank to issue a banking product that implements the concept of “soft computing”. Methods. The use of fuzzy logic methods in credit scoring is not new, but it is not widely used in practice because it is expensive to integrate into existing systems. Each bank uses its own indicators of the client's financial reliability in scoring. Most of the indicators in banks are the same, but when deciding to issue different banking products, they have different numerical values. The data of the standard scoring methodology of a real bank were taken as the initial data. To predict a bank's decision to issue a banking product to a client, a fuzzy model was applied, production rules were proposed, and membership functions were determined. The model focused on the simultaneous processing of incoming data from multiple clients and for different banks and different scoring models. Results. The developed mathematical model for assessing the client's rating and predicting the decision to receive a banking product based on the fuzzy inference rule. The obtained results are proposed to be used in a multi-banking web-oriented system of providing banking products to corporate clients.
