Method of Forming the Context of Advertising and Target Audience based on Associative Rules Learning Khrystyna Lipianina-Honcharenko 1, Taras Lendiuk 1, Anatoliy Sachenko 1,2, Jacek Wołoszyn 2 1 West Ukrainian National University, Lvivska Str., 11, Ternopil, 46000, Ukraine 2 Kazimierz Pulaski University of Technology and Humanities in Radom, ul.Malczewskiego 29, 26-600 Radom, Poland Abstract Nowadays, important mechanisms of study are content and techniques of its creation, the problem of influencing the target audience, which itself seeks to shape communication processes. Internet content occupies a position of powerful communication technology, which continues to grow rapidly and gain influence. Creating a large number of advertisements, especially texts, is extremely expensive. Therefore, it is worth considering how generate these texts automatically. In this regard, it is possible to assume that the development of a method of forming the context of advertising and target audience based on learning associative rules is relevant and can increase the effectiveness of advertising, and thus reduce the cost of online advertising of higher education institutions. The input data used a survey of students majoring in Computer Science, regarding admission. The 152 students took part in the survey and answered 10 questions. The experimental results confirmed, the proposed method enabled to increase the effectiveness of advertising on social networks at least in 23%, and reduce the price in 90%. Keywords 1 Data analysis, advertising content, Associative Rules Learning, Apriori algorithm, Facebook. 1. Introduction The value of advertising is crucial for a company, because only this can make people aware of the company's product and, doing so, can create a good opportunity to sell it to customers [2]. The manual work of a large number of advertisements, especially texts, is extremely expensive. Therefore, it is worth considering how to generate these texts automatically. Therefore, we can assume that the development of a method of forming the context of advertising and target audience based on learning associative rules is relevant and can increase the effectiveness of advertising, and thus reduce the cost of online advertising of higher education institutions. This work is devoted to this topic and it is distributed as follows. Section 2 discusses the analysis of related work; section 3 presents a method of forming the context of advertising and the target audience based on the associative rules learning. Section 4 presents the implementation of the method. Section 5 presents the conclusions of the study. 2. Related Work Given the complexity of the modern digital advertising ecosystem, there are many studies describing the impact of advertising content on social networks on attracting customers [19], using data from Facebook in: medicine [20], psychology [21], sociology [22], politics [23] and others.

CEUR Workshop Proceedings (CEUR-WS.org) 25] provides an understanding of social networks for higher education institutions such as Instagram, Pinterest, Snapchat and WhatsApp. In [13], a model is proposed that is able to use its targeting strategy in accordance with the received feedback. The model uses the Thompson Sampling algorithm applied to the user space. [1] a set of models of regression, cluster analysis and analysis of association rules to find patterns of user behavior in relation to marketing campaigns, taking into account user characteristics and financially significant indicators. The aim of the article [12] is to study the analysis of social media data using machine learning tools; new approach to social media marketing strategy uses the Waikato Knowledge Analysis Environment (WEKA). In [5] the article implemented the level of the aspect of mood analysis, based on machine learning algorithms of SVM and NB classification. In [17] the study analyzed the various needs of customers, focusing on online advertising based on methods of classification, segmentation and clustering. In [16] the model of selection of the optimal amount of advertising on various Internet resources is analyzed in order to achieve the desired coverage of the target audience. In addition, the method of multi-criteria optimization with the definition of the obtained objective function is considered, which allows considering simultaneously the various aspects of media selection issue and optimal budgeting and budget allocation. The proposed approach [2] draws on knowledge that can support several solutions, ranging from marketing campaigns for each customer segment, redesign of the store layout to product recommendations. In [15] the development of advertising art design on the basis of information technologies is mainly investigated. In a study [4, 26], it is proposed to apply the training of association rules to find influential bloggers in time using the Apriori algorithm. An improved Apriori algorithm has been proposed to identify the relationship between the TECP and the thirty-five factors, which cover four categories of household characteristics, including housing, socio-demographic, household appliances and heating, and energy attitudes [9]. In [10] a new effective system of recommendations based on the Apriori algorithm for user requirements was proposed. Article [18] proposes the generation of advertising texts based on keywords that take into account product information. Ins [3] was developed a web-based system of recommendations for choosing a property using the method of content-based filtering. The referral system provides information about properties based on user behavior by searching for advertising content that the user previously searched for. [11] presents an intelligent management system for advertising on social networks, based on data analysis techniques to automatically create ads. The above-mentioned works mostly analyze the actions of users on online advertising. There are also a number of works that present research on methods of associative rules learning. There are also works that use different approaches to the formation of content and target audience of Internet advertising (analogues). Therefore, goal of this paper is to develop a method of forming the context of advertising and the target audience based on the associative rules learning. The novelty of the work is the formation of the most profitable (in the economic aspect) text of the Free Economic Zone advertising and the corresponding target group, which will increase the effectiveness of the advertising campaign based on learning the rules of association. 3. Proposed Method To reduce the time spent on the formation of advertising content for the target audience, the authors have developed a method of forming the context of advertising and the target audience based on the associative rules learning. The proposed method is illustrated schematically (Fig. 1) and is represented by the following steps: Step 1. Conduct a survey of students (Block 1). It is important to determine the gender characteristics of the respondents, as this will make it possible to determine the target audience in the future. Convert to csv format (Block 2). 1 2 Survey Formatting in csv. of students 4 3 Convert data Definition to a list of support Learning associative rules 5 method Apriori Search 5.1 for 5.2 Remove pairs of rare pairs of items elements 5.3 Forming rules Element X => Element Y 5.4 5.5 Calculating Lift calculation confidence 6 7 Formation Derivation of context of advertising rules and target audience Figure 1: Algorithmic structure of forming the context of advertising and target audience based on learning associative rules Step 2. Calculation of support for each individual element (Block 3). Support is simply the number of transactions during which a particular product (or combination of products) occurs. Step 3. Conversion of data into a list (Block 4). Step 4. Start (Block 5) learning associative rules based on the Apriori method [6]. Step 4.1. Finding support for frequent sets of elements (Block 5.1). Search for pairs of items that appear most often in pairs. The Apriori algorithm ignores all pairs that contain any of the rare elements (Block 5.2). Step 4.2. Formation of rules (Block 5.3). The most frequent sets of elements, converted into association rules, in the format: Element X => Element Y. Step 4.3. Calculation of confidence (Block 5.4). Confidence shows the percentage of cases in which this rule applies. Step 4.3. Elevator calculation (Block 5.5). Raising a rule is an indicator of effectiveness, which indicates the strength of the relationship between the products in the rule. Raising the rule is determined by the following formula: 𝑃 𝑋∩𝑌 𝑙𝑖𝑓𝑡 𝑃 𝑋 𝑃 𝑌 where, P is the probability of the frequency of combination of elements in the generated rule. Step 5. Output of results-rules (Block 6). Step 6. Creating the context of advertising and target audience (Block 7), for higher education institutions on the basis of the received rules. 4. Experimental Results The Python language was chosen to conduct the method of forming the context of advertising and the target audience based on th associative rules learning. The input data used a survey of students majoring in Computer Science, regarding admission. 152 students took part in the survey and answered 10 questions. All students’ feedbacks are in .csv format. The sample is representative, as the survey was conducted among students majoring in Computer Science, who themselves have recently been faced with the choice of where to enter, so their feedback is the most informative for this type of advertising. Before starting the analysis of the rules of the association, first determine the frequency distribution of the elements (Table 2). The chart shows that the majority of male respondents, as well as the highest number of answers, said that they found information on their own in social networks, majoring in Computer Science. Table 1 Response rate Item name Count Male 67 independently found information 59 I saw a lot of interesting information on social networks 41 advised familiar relatives 39 Female 37 Interest in computers 35 The presentation of the specialty by the representatives was interesting 33 Interest in design 32 Interest in technology 30 Passed here for public training 29 Augmented reality 29 I got a call and was convinced that it would be interesting to study here 29 Representatives of the specialty came to our school 20 Internet of Things 17 Robotics 15 Internet of Things.

Next, we will use this information as a guide when setting a minimum support threshold. Table 2 The most common answers Index Item Count Percentage 13 augmented reality 29 4.93 40 passed here for public training 29 4.93 47 interest in technology 30 5.10 45 interest in design 32 5.44 37 interested in the presentation of the specialty by 34 5.78 representatives 46 interest in computers 35 5.95 34 female 37 6.29 39 advised familiar relatives 39 6.63 31 saw a lot of interesting information on social networks 41 6.97 41 independently found information 59 10.03 43 male 67 11.39 After converting the dataset into the desired list, we will display the results, namely the rules, which in the future will allow to form the context of advertising and target groups. Therefore, after starting the algorithm was generated: 1. Counting sets of items of length 1: 48 candidates were found for sets of length 1; Found 15 large sets of items of length 1. 2. Counting sets of items of length 2: 105 candidates were found for sets of length 2; 32 large sets of items of length 2 were found. Based on the experimentally significant parameters of the algorithm, the generated rules are filtered. Parameters: min_support = 0.11 – defined as the percentage of most frequent responses; min_confidence = 0.65 – this probability of determining the rules is sufficient and in experimental studies showed quite good results for this sample. Rules: {male, interest in design} -> {augmented reality} (conf: 0.737, supp: 0.135, lift: 1.965, conv: 2.375); {advised by familiar relatives, passed here for public education} -> {male} (conf: 1.000, supp: 0.115, lift: 1.552, conv: 355769230.769); {saw a lot of interesting information on social networks, advised familiar relatives} -> {male} (conf: 0.857, supp: 0.115, lift: 1.330, conv: 2.490); {saw a lot of interesting information on social networks, interest in technology} -> {found information on his own} (conf: 0.706, supp: 0.115, lift: 1.244, conv: 1.471); {independently found information, interest in computers} -> {male} (conf: 0.800, supp: 0.154, lift: 1.242, conv: 1.779); {interest in technology} -> {independently found information} (conf: 0.700, supp: 0.202, lift: 1.234, conv: 1.442); {passed here for public training} -> {male} (conf: 0.793, supp: 0.221, lift: 1.231, conv: 1.720); {advised familiar relatives, interest in design} -> {male} (conf: 0.778, supp: 0.135, lift: 1.207, conv: 1.601); {interest in computers} -> {male} (conf: 0.771, supp: 0.260, lift: 1.197, conv: 1.556); {Augmented Reality} -> {male} (conf: 0.690, supp: 0.192, lift: 1.071, conv: 1.146); {saw a lot of interesting information on social networks} -> {male} (conf: 0.659, supp: 0.260, lift: 1.022, conv: 1.042). Almost all of the received rules mention the gender of the respondent (male), which indicates the main target audience for the specialty “Computer Science”. Rules that are more than two elements of the answer, allow to create content for advertising. Let's form some examples of content (Table 3). Table 3 Formation of advertising content in relation to the generated rules # of variant Rule Content 1 {male, interest in design} ‐> {Augmented Interested in Design, Try Yourself in reality} Augmented Reality 2 {advised by familiar relatives, passed We Are Recommended When Public here for public education} ‐> {male} Education Is Important 3 {saw a lot of interesting information on We are recommended after browsing social networks, advised familiar our social networks relatives} ‐> {male} 4 {saw a lot of interesting information on Interested in technology, visit our social social networks, interest in technology} ‐ networking pages, there's lots of > {male} interesting information 5 {self‐found information, interest in Interested in Technology, Visit our Social computers} ‐> {male} Networking Pages To compare the effectiveness of the generated advertising content based on the associative rules learning, a comparative experiment was conducted on Facebook on the business page “Computer Science of ZUNU”. The first option (Option 0) advertising (Fig. 2), developed on the basis of the rules identified in previous research, namely: The greatest interaction with the video advertising of Facebook “Computer Science ZUNU” had males in the age category 18-25, 35-55 [7]; Male and female clients in the age category of 40-55 had the greatest interaction with the ZUNU Computer Science business page. Variant 0 Figure 2: Previous version of the advertisement “Computer Science” of the Western Ukrainian National University on Facebook Fig. 3 presents an advertisement formed on the basis of learning associative rules, a comparative experiment was conducted on Facebook on the business page “Computer Science of ZUNU”. The content used is from Table 3 and the target audience is male for all age groups. Variant 1 Variant 2 Variant 3 Variant 4 Variant 5 Figure 3: New variants of advertising "Computer Science" of the Western Ukrainian National University on Facebook Table 4 presents a comparison of the effectiveness of the generated advertising content based on the associative rules learning, in the period from May 4, 2021 – May 31, 2021 with all content options, including the old. Table 4 Comparison of the effectiveness of the generated advertising content Advertising Results Coverage Readings Price for the variant result Index Changes Index Changes Index Changes Index Changes Variant 0 120 100% 4498 100% 5395 100% 0,23 100% Variant 1 147 123% 6561 146% 8776 163% 0,08 37% Variant 2 197 164% 6364 141% 6560 122% 0,06 25% Variant 3 240 200% 8561 190% 8192 152% 0,02 10% Variant 4 160 133% 5442 121% 6671 124% 0,12 53% Variant 5 196 163% 7024 156% 8867 164% 0,03 14% Table 4 shows that all variants of the new ad gave improved results. The result indicator shows how many times customers have been in contact with the ad. Advertising performed best in Option 3 (Fig. 4), as it performed 100% better than Option 0. Option 3 performed best in all indicators. Namely, the coverage is 90% better than option 0 and 52% better in terms of the number of impressions. It also reduced the price for the result by 90% in option 3. 2,5 1,2 2 1 0,8 1,5 0,6 1 0,4 0,5 0,2 0 0 Variant 0 Variant 1 Variant 2 Variant 3 Variant 4 Variant 5 Results Coverage Readings Price for the result Figure 4: Comparison of the effectiveness of the generated advertising content Thus, the proposed method enabled to increase the effectiveness of advertising on social networks at least in 23%, and reduce the price in 90%. Moreover, the authors believe that growing the number of student surveys can increase the quality of associative rules learning as well as get better keywords for content formation. That will lead to increasing the effectiveness of advertising and reducing its costs respectively. 5. Conclusions Developed method of forming the context of advertising and target audience based on the associative rules learning makes it possible to increase the effectiveness of advertising, and thus reduce the cost of online advertising of higher education institutions. Also, the developed method will allow to form rules between the answers of respondents for the formation of advertising content and the definition of the target group. To implement the developed method, we used a survey of students majoring in Computer Science, regarding admission. 152 students took part in the survey and answered 10 questions. The proposed method enabled to increase the effectiveness of advertising on social networks at least in 23%, and reduce the price in 90%. Moreover, the authors believe that growing the number of student surveys can increase the quality of associative rules learning as well as get better keywords for content formation. That will lead to increasing the effectiveness of advertising and reducing its costs respectively. Unlike analogues [3, 11, 18] the developed a method enables to form rules between the answers of respondents, construct the advertising content and determine the target group. In the future, the authors plan to develop the information system that will automatically generate the content of the advertising message and select the target audience using the deep learning methods [27, 28]. 6.
