                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%.

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. Research [24,

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).

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.

    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:

         {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).

   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.

   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.

    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].
