Публікація Example of use of virtual promotion map(Національний технічний університет "Харківський політехнічний інститут", 2022) Orekhov, Sergey Valerievich; Kopp, Andrii Mykhailovych; Orlovskyi, Dmytro LeonidovychThe paper presents an example of using new technology to solve the problem of promoting goods and services according to the 7P concept. The technology was called virtual promotion. The reason for its occurrence is a decrease in the effectiveness of the currently classical search engine optimization methodology on the Internet. The task of the latter is to bring the given corporate WEB resource to the first place in the search server’s answers to the requests of potential buyers. Virtual promotion is based on two ideas. The first is based on marketing theory when to sell a product or service, you need to build a marketing channel. The second is that a search server is an intelligent machine. Then, to get the first position, we need to teach the virtual space, which consists of Internet nodes, to activate in such a way that the number of links to the WEB page with the desired product is maximum. To implement these ideas, two objects are synthesized as part of the virtual promotion: a semantic kernel and a promotion map. A semantic kernel is a description of a product or service or a training sequence of keywords. A map is a set of nodes on the Internet, where the semantic core should be placed to attract the maximum number of buyers of the product. The map is also a variant of marketing channels on the Internet. The paper considers an example of a situation where a semantic core and a minimal map have already been created using the classical approach (search optimization). In this case, the classic approach gave an increase in the number of visits to the WEB site, but there was not a single buyer of the product for six months. That is, the classical approach improved the key performance indicator, but it did not affect the sales performance in any way. The paper demonstrates how virtual promotion forms such a modification of the map that gives a given result in a given period. At the same time, it is not enough to synthesize a new map. It is necessary to apply a special mechanism for its implementation. For this purpose, the paper shows a real task of inter-functional coordination, which makes it possible to implement a promotion map. Real data for 2021, which was used to promote the product on the Ukrainian market, is given. The introduction of the new version of the map resulted in the first two orders within the first two weeks.Документ Problem of classification of semantic kernels of web resource(Національний технічний університет "Харківський політехнічний інститут", 2022) Orekhov, Sergey Valerievich; Malyhon, Hennadiy Vasilievich; Stratiienko, Nataliia KostiantunivnaThe article presents a new theoretical basis for solving the problem of situational management of semantic cores identified on the basis of WEB content. Such a task arises within the framework of a new phenomenon called virtual promotion. Its essence lies in the fact that a real product can exist in two realities: online and offline. According to marketing theory, the lifetime in two realities is the same. However, in the online mode, the goods exist independently and in accordance with the laws of the use of Internet technologies. Therefore, based on the concept of a marketing channel, it was proposed to consider a message in such a channel as a semantic core. The core is a specially selected set of keywords that briefly describe the product and the corresponding need. It has been proposed that each need forms a so-called class of need. Therefore, the product description will either belong to this class or not. In addition, a product can be described by a different set of keywords, which means that different descriptions of the same product or several products, if there are any for sale in the enterprise, will fall into the demand class. As a result, in this work, it was proposed to consider the center of this class as the so-called K-candidate. It is the K-applicant that will be the semantic core that will be considered at the current iteration of the situational management process. In addition, in order to move from one situation to another, in other words, from one core to another, it is required to have such an alternative core. It can be safely taken either from the neighborhood of the need class center (K-applicant), or the center of another class (another K-applicant), if the product can cover several needs of a potential buyer. Then the actual task is to classify the classes of needs based on the text corpus in HTML format. Having a text corpus at the first stage, the task of synthesizing semantic cores is realized, and then the classification task itself. This article proposes the formulation of the classification problem, taking into account the features that the Internet technologies contribute to search engine optimization. In particular, it is proposed to use four metrics from the category of WEB statistics. And then it is proposed to use the clustering method to identify classes of needs, taking into account the fact that the K-applicant is presented as a semantic network or as a graph.Документ Metrics of virtual promotion of a product(Національний технічний університет "Харківський політехнічний інститут", 2021) Orekhov, Sergey Valerievich; Malyhon, Hennadiy VasilievichAn approach to the mathematical description of the criterion for the effectiveness of a new object of research – virtual promotion is presented in the paper. The emergence of this new object of research is connected, on the one hand, with the classical theory of marketing, and on the other with modern Internet technologies. Marketing is based on the 4P principle: product, price, location and promotion. Promotion is a component of this principle. But in modern conditions, this phenomenon is changing under the influence of the Internet. Now this 4P component is becoming a fully virtual instrument. The traditional scheme of promotion functioning is as follows. A message is created to a potential buyer and the delivery channel of this message undergoes a change. It is based on the principle: money – goods – money. While the new sales scheme is described by the scheme: we attract a client, make money on a client, we spend money. In the new scheme, we deal with product knowledge in the form of the so-called semantic core of web content. Knowledge describes for a potential client how a given product can cover his need for something. Using the logistic principles of the transfer of goods, this semantic core is loaded into the specified Internet nodes. That is, virtual promotion is formed as two channels: logistics and marketing. The first one performs three operations: concentration, formatting and distribution of semantic cores on the Internet. The second manages this process, forming a virtual promotion map. This map is a graph of Internet nodes. It is required to define such a tree of Internet nodes so that virtual promotion has maximum efficiency. The paper analyzes modern metrics related to the processes of search engine optimization on the Internet. Unfortunately, these metrics evaluate only statistically after the fact of visiting a web resource or the budget of the Internet site in which the advertising message about the product was placed. Therefore, based on the conversion metric, a criterion for the effectiveness of virtual promotion was proposed in the work, which takes into account both the attractiveness of the semantic core and the attractiveness of the Int ernet site where the semantic core will be located. The criterion reflects the income that we receive depending on the attractiveness of the semantic kernel and the Internet site.Документ Modelling semantic kernel of web resource(Національний технічний університет "Харківський політехнічний інститут", 2021) Orekhov, Sergey Valerievich; Malyhon, Hennadiy VasilievichThe article presents an attempt to describe mathematically the effect of the semantic kernel of a web resource on the Internet. In accordance with the theory of marketing, the product that we want to sell on the network is characterized by the following basic properties: price, time and place. In other words, a potential buyer wants to receive a given product in the right place at a given time. To satisfy this need, it is necessary to use the classic component of marketing, product promotion. However, this component is now becoming a fully virtual instrument. This tool functions in a hypertext, video and image environment. Therefore, the user analyzes the meaning of these elements in order to get the desired product. The results of web projects carried out in this area indicate the emergence of a new phenomenon, which reflects the main meaning of virtual promotion – this is the semantic core. The core is a short annotation of the main properties of the product, its location and time of appearance. Therefore, the purpose of this article is both a presentation of a new object of research and a mathematical description. It is assumed that the semantic core is formed on the basis of natural language terms. In other words, the semantic core is a set of keywords that are grouped by meaning. We propose to use data mining approaches for clustering to group terms. The classic clustering method at the moment is k-means. The article presents a model of the semantic core based on this method. This method and its distance function are considered as the second stage of web content processing. At the first stage, web content is converted into a semantic web. However, the k-means technique has significant drawbacks when modeling the semantic core. Therefore, in the development of this idea, the work shows an alternative way to modeling the kernel. As an alternative approach, the construction of clusters based on the concept of maximum flow is considered. This approach has the significant advantage that the type of links in the semantic network overlaps with the type of distance function in this method. As a result, on a real web project, the effect of the connection between the semantic core model and the level of new users of the web resource was demonstrated over the past five years.Документ Frameworks analysis and evaluation used in the web-application development(Національний технічний університет "Харківський політехнічний інститут", 2020) Selivorstova, Yuliia Romanivna; Liutenko, Iryna Victorivna; Orekhov, Sergey ValerievichThis article presents the approaches used to analyze and evaluate modern frameworks that are used in the development of web applications. The analysis and evaluation of frameworks allow you to choose the framework that can be most efficaciously used for each specific case of software development. The popularity of using frameworks in the development of web applications is due to a significant reduction in the time and other resources spent on project execution. The article describes the concept of a framework as a technology for developing web applications and the classification of frameworks. Five main types of frameworks are briefly described. Criteria for the rationality of using frameworks for developing a web application are considered. The advantages and disadvantages of using them when creating web-oriented software are given. When evaluating web applications according to COCOMO model, software options were considered with the use of frameworks in development, and without the use of frameworks. This article provides an overview of the families of modern Back-End frameworks. A comparison of the functionality of the Back-End frameworks of six manufacturers for commercial software solutions is carried out. The choice of criteria for assessing the quality of frameworks is examined. As a basis, when choosing quality criteria, it is proposed to use the ISO 25010 standard. The coefficients of importance for the evaluation criteria, the values of which were obtained with the help of experts, are given. When forming the final assessment of the frameworks, such characteristics as functional suitability, security of working with data, modifiability, interface quality, interaction with payment systems, and integration with JIRA, compatibility, productivity were mentioned. General quality scores were obtained for all the frameworks under consideration. Assessing the quality of frameworks allows you to improve the process of developing a web-oriented software product, the purpose of which is to obtain a web application of a given quality.Документ Virtual promotion knowledge management technology(Національний технічний університет "Харківський політехнічний інститут", 2020) Orekhov, Sergey Valerievich; Malyhon, Hennadiy VasilievichThe article presents a new concept of “Management of knowledge about virtual promotion” on the Internet. Usually a real product or service is being divided into four components (product, price, promotion and place) in accordance with the theory of marketing. One of the components is a product promotion. But now this element is becoming a fully virtual tool. It is necessary to consider product promotion as an image or a copy of a real product in a virtual space that lives in parallel on the network. Therefore, the objective of the paper is the presentation of a new object of research based on the experience of more than thirty real projects performed in Ukraine, USA, Europe and Canada. We regard the promotion as a software product, which works according to principles of knowledge management and machine learning. It is proposed that virtual promotion is characterized by four views: customer or user, data, technology and marketing. Thus, the structure of virtual promotion business process was presented. It includes four steps: selection of hypertext sources, knowledge representation and extraction, semantic kernel building and quality criterion evaluation to stop the process. Based on the process structure the research tasks were identified. The central task is semantic kernel forming. Then the software architecture was developed. IT solution contains CRM system as accounting tool and Web site as an image of virtual promotion. CRM plays main role as a commander center. Here we form semantic kernel and then send it via marketing channels such as Web site, telegram or viber accounts. Another part of IT solution is Web service such as Bing API or Google API. They help us to build the kernel. Also the paper demonstrates the list of future tasks that should be solved and the example of real project of proposed approach.
