                 Abstract
                 In this paper, we examine the impact of digital technologies on the labor market of HR
                 professionals. With this purpose, digital trends in the creation of new operational processes in
                 personnel management have been studied; the conditions for the implementation of digital
                 technologies have been substantiated; the content of the main stimulants that contribute to the
                 implementation of digital technologies in personnel management has been determined. The
                 importance of digital culture as the basis of the organization’s corporate culture according to
                 the trends of world digital culture is emphasized; the influence of stimulants on the state of
                 the labor market of HR specialists is assessed. The study is based on an array of official
                 statistical information from the State Employment Service of Ukraine. The applied
                 methodology of taxonomy made it possible to determine the degree of balance of the labor
                 market of HR specialists in Ukraine in January 2020 - October 2021. And this methodically
                 ensures monitoring of the situation in the labor market of specialists in the field as a whole.
                 Factors that balanced the indicators of vacancies and unemployment in the labor market were
                 identified. Recommendations have been formulated for the relevant state institutions that will
                 help improve the situation in the labor market of HR specialists. In this paper, we consider
                 the expert opinions of HRM practitioners who believe that the possession of relevant digital
                 competencies for employees in this field is a basic condition for the formation of a modern
                 labor market of HR professionals, confirming our results and conclusions.

1. Introduction
   Since 2020, the labor market has changed under quarantine restrictions, and the global pandemic
has catalyzed these changes. As a result, the need for remote work has increased exponentially. The
pandemic has accelerated the use of digital technologies in any activity (business, education, services,
etc.) where the main resource is the staff. With the development of digital technology, routine and
cumbersome business tasks can be digitized and entrusted to intelligent systems, and human resources
can be spent on more complex, strategic tasks.
   Digitalization brings several positive changes, helping companies to identify the strengths and
weaknesses of interaction with employees and to conduct a thorough assessment of staff from
onboarding to offboarding employees; accelerate the process of finding candidates for vacant

Management (HRM) results in the company, etc.
    Consideration of the synergistic impact of digital technologies on the labor market of HRM
specialists makes it possible not only to accelerate the implementation of business tasks but also to
improve their quality and efficiency. This is due to the identification and involvement of stimulators
of digital technology in personnel management.
    The effective implementation of digital technologies in the activities of companies is determined,
in particular, by the relevant competencies of HRM specialists, which requires constant monitoring of
the labor market situation by individual categories of workers and in general.
    The described relevance of the research has necessitated the identification and study of the impact
of digital technologies on the balance of the labor market of HR professionals in Ukraine. Our study
aims to determine the impact of digital technologies on the labor market of HR specialists. To achieve
this aim, as a task it is proposed to develop the Mining Data tools to create a methodology for
monitoring the labor market of HR professionals.

2. Related Works
    In their work [1], the authors emphasize that the labor market is characterized by an imbalance
between the supply and demand of labor due to structural changes in the economy associated with the
introduction of information technology. The rising unemployment is among the challenges of the
labor market. According to the authors, the digitalization of the economy leads to the need to
strengthen government regulation of business and provide social guarantees for workers.
    In the study [2] it is proposed to evaluate the effectiveness of HRM activity based on cluster
analysis, which belongs to the class of multidimensional analysis (statistical clustering methods). In
the article [3] the authors used empirical and theoretical methods to study the impact of the pandemic
on the labor market in the 4th industrial revolution.
    Experts from the European Commission's science and knowledge service [4] emphasize that new
technologies will change millions of jobs in the European Union (EU); digital and soft skills are
becoming increasingly demanded in the context of the digitalization of society; technology is
becoming a key driver of new forms of work; employment differentiation processes are taking place
in the EU.
    Researchers in [5, 6] emphasize that digitalization is the driving force of transformations in the
field of employment and emphasize the prospects for the use of digital technologies to simplify
procedures in job creation. The authors of [5] studied the differentiation of the level of the labor
market in individual countries, which is associated with the influence of information technology.
    The authors of [7] emphasize that digitalization will change the traditions of doing business and
other areas. But such a phenomenon is becoming a serious challenge in the labor market. Therefore,
the authors proposed to study the perceptions of EU citizens regarding digitalization and take into
account the differences between individual socio-demographic groups. To achieve the objectives of
the study, the authors used a combination of econometric methods and cluster analysis.
    The authors of the study [8] combined the results of the study of the labor market with the
phenomena of digitalization of the economy and concluded that it is necessary to make adjustments to
provide digital skills in the technical education system in Brazil.
    Digitalization is seen by some researchers as a threat to the balance of the labor market, which
poses new challenges for workers and employers. These new challenges require new competencies
from employees and new forms of work organization from employers [9].
    Source [10] contains new methods of collecting and processing statistical information in the labor
market, which would allow more informed decisions by market participants in the digital
transformation of the economy and society.
    Authors of [11] link the processes of digitalization with rising unemployment, thus identifying
digitalization as one of the factors that cause social risks. Therefore, the authors conclude that it is
necessary to develop an appropriate adaptive strategy at the state level to reduce the impact of such
risks.
    A team of researchers in [12] studied various areas of the labor market and the impact of
digitization on them, assessed the consequences, and created forecasts of digital transformation for the
labor sector through the prism of the phenomenon of "Gig Economy".
    The authors of [13] proposed a model of digitalization management in the labor market, which
provides different scenarios. According to the authors of this study, the forced scenario of
digitalization is the most promising, and the model of probable transformations of the labor market is
applied to this scenario. This study aims to improve the state strategy for labor market development in
the context of digitalization.
    Research [14], which is devoted to the development of effective HRM systems using modern
digital technologies, in our opinion, is somewhat controversial, as it justifies the prospects of remote
work with digitalization as a whole, that is, without distinction between digital transformations and
Gig Economy.
    In another study [15] the authors conclude the prospects for the impact of information technology
on HRM based on the results of comparative analysis of traditional technologies and technologies for
the digitization of personnel processes. They have analyzed the experience of such activities of many
organizations around the world.
    The conceptual and categorical apparatus in the field of digital technology is not sufficiently
organized. For instance, there is parallel use of the categories such as "digitization", "digitalization"
and "digital transformation".
    Digitization is one of the stimulators of the development of digital technologies, which involves
the process of converting information from paper and other media into digital format for further use in
computer systems.
    Digitalization lies in the conversion of operations, communications, business functions, business
models, and processes into digital format, resulting in a combination of traditional business functions
with digital ones (e.g., traditional human resource management with relevant digital tools).
    Digital transformation is the evolutionary transformation of activities, processes, competencies,
business models to make fuller use of the potential of technological change and opportunities of
digital technologies.
    Digitalization of personnel management is the most important change in the activities of modern
organizations and its application is growing exponentially. HR must apply new methods and
procedures to keep up with the rapid modernization of staff. The advantages of digital technologies
are the creation of new operational processes of personnel management, which help to improve
communication, collaboration, and access to analytical data [16].
    At the very least, the implementation of digital technologies requires an appropriate level of digital
competence, as formulated by A. Ferrari based on a thorough analysis of several national and
international projects and initiatives. These include the set of knowledge, skills, attitudes (including
abilities, strategies, values, and awareness) required to use information and communication
technologies and digital media for performing tasks; problem-solving; communication; information
management; cooperation; creation and dissemination of content; building effective, productive,
responsible, critical, creative, independent, flexible, ethical, reflective tools for work, leisure, joint
activities, learning, communication, meeting consumer needs and providing opportunities for the
realization of rights [16].

3. Methods and Materials
   Methodological approaches to study the impact of digital technologies on the balance of the labor
market of HR professionals are proposed. The proposed study is based on Data Mining tools as a
methodology and process for identifying large data sets that accumulate on various information
resources. These data are necessary for our study to make decisions in the sphere of impact on the
labor market of HR Specialists.
   The novelty of our study is the development in HR - the combination of Data Mining approaches.
Traditional Data Mining methods are association, classification, cluster, forecasting, goal tree, neural
networks, anomaly analysis, and pattern tracking methods.
    These methods can be divided into descriptive and prognostic, which perform different functions.
These methods can be implemented using technology, statistical, and machine learning methods.
    Using the technology of statistical methods, Data Mining allows scaling the variability of the labor
market of HR specialists, i.e., to reduce to a specific scale. These approaches involve assessing the
dynamics of the unemployed and vacancies of HR professionals by individual categories of workers
and an integrated assessment of the degree of balance of the labor market of HR professionals. Such
an integrated assessment consists of a comparison of two taxonomic indicators (taxonomic vacancy
indicator and taxonomic unemployment indicator) in dynamics.
    The author of the study [17] emphasizes the importance of scientific and theoretical support for the
proper qualification of employees and the acquisition of appropriate skills to match supply and
demand in the labor market. The author proposed clustering as one of the Data Mining methods for
effectively classifying information about vacancies.
    Fundamental approaches to the application of taxonomic analysis in economic research are
presented in [18]. The value of this approach lies in the possibility of creating an integrated
assessment of a complex phenomenon. The taxonomic analysis is a subtype of methods of
multidimensional analysis, which have recently become popular due to the growing complexity of
economic systems. It should be noted that among the methods of multidimensional analysis, cluster
analysis is most often used, and the potential of taxonomy is used insufficiently.
    The process of calculating the relevant taxonomic indicators included the following stages [18]:
construction of a matrix of observations; standardization of elements of the observation matrix;
formation of a matrix of standardized values; construction of a vector – a standard; determining the
distance between the elements of the matrix and the vector – the standard; calculation of taxonomy
coefficient in dynamics (Table 1). The value of the taxonomic indicator as an integral indicator of a
complex phenomenon is in the range from 0 to 1, which makes it possible to create dynamic
comparisons and states of individual objects as the development of data mining tools.

   To substantiate the degree of balance of the labor market of HR professionals, a method of
comparison was used, which consists in comparing the dynamics of taxonomic indicators of vacancies
and unemployment over the study period.
   To determine the prospects for the development of the labor market of HR professionals, the
method of expert assessments was used. For this, the best practices of HRM and methods of rating
HR professionals in Ukraine were studied, which also includes the sign of mastery of modern digital
technologies.
   Since the research issues are quite variable and the labor market as a whole, it is considered
appropriate to use official statistical resources, information resources of consulting companies and
professional associations, and the most relevant publications indexed in scientometric databases.
   The calculations, the results of which are presented in the work, were performed using Google
spreadsheets and spreadsheets Microsoft Excel 2016 MSO (64-bit version).

4. Experiment
    The technology of the proposed study involves using the potential of taxonomic analysis to
monitor the state and dynamics of the labor market. To this end, it is necessary to study the factors -
stimulants that harmonize the labor market. From our point of view, the main stimulators of the
implementation of digital technologies in personnel management are as follows:
    1. Greening the approaches in the organization of HR specialists (by reducing the documentation
in paper form). With the traditional use of e-mail and Microsoft Office, many HR processes are not
carried out "paperless" in their daily activities. This results in a huge number of forms for orders,
applications for benefits, applications for leave, and other documents that require considerable effort
for tracking and organization, as well as the time spent on their processing. Execution of documents
requiring interdepartmental approval means that one sheet of paper is moved across the floors of the
building (between levels of hierarchy) to obtain the necessary signatures. Human resources
departments in large organizations process hundreds or thousands of documents every day. Some
companies hire clerks to enter data from paper documents in an Excel worksheet. This stimulant is a
phenomenon of digitization.
    2. The emergence of applications that promote greater independence of employees. The use of
"smart" applications has simplified staffing processes for employees and changed the way employees
interact with the organization. Deloitte [19] has developed a system that tracks the time spent by
consultants with their clients, paid hours, and compares them with other companies. Based on the
results of the comparison, the system provides suggestions for improving inefficient work styles.
    3. Automation of routine processes of personnel records management. Automation eliminates
hours of manual work. In addition, manual work contributes to random (systematic and non-
systematic) errors. For example, such mistakes occur when writing plans and reports of the recruiter,
planning meetings with candidates, finding vacancies, performing HR analytics, and so on.
    4. Recruitment through social networks. Recruitment has changed with the advent of social
networks. For example, LinkedIn has changed the traditions of social networks and facilitated the
interaction of potential candidates for vacant positions and recruiters. The TalentNow website [20]
contains information that 80% of employers have found passive candidates through social networks. It
is also noted that 89% of companies plan to recruit candidates through social networks, which
indicates that the trend will continue to grow.
    5. Virtual reality (VR) to train and ensure the appropriate level of moral and psychological
climate in the team. Learning outcomes are always improved through the involvement of practical
experience. With the advent of virtual reality (VR), companies can model real-life examples while
learning. For example, retailers use virtual reality technology to prepare employees for Black Friday
sales. For example, simulations using experience and data will demonstrate how the crowd responds
to products sold by measuring in-store customer traffic, as well as how to respond to confrontations
and manage the crowd.
    6. Gamification in the work. Applying game dynamics in typical non-game contexts helps
companies better engage employees. For example, companies may reward employees when they
achieve their key performance indicators (KPIs), acknowledging their efforts in resolving difficult
situations. Companies can also implement real-time leader boards to create friendly competition
between peers. This encourages employees to interact with each other and increase their productivity.
For example, there is an experience in rewarding employees when they receive fewer sick leaves by
points that can be used to purchase products manufactured by the company or NFT.
    7. Study of employee needs. It is important that the understanding of the needs of the company's
employees corresponds to the real scenario. Often companies tend to make assumptions or rely on
industry benchmarks. As millennials join the workforce, companies must adapt to changing
demographics and focus on the concept of generational theory. A separate area of such activities is to
take into account the interests of employees with special needs.
    8. Continuous learning. Training for beginners and employees in the digital age is no longer a
problem. Cloud learning systems, online learning platforms solve this problem, where the only
requirement is the ability to connect to the Internet. Text, video, and audio can be accessed at the
touch of a button. The authors emphasize the need to constantly maintain the appropriate level of staff
qualifications to ensure their validity [21]. In combination with VR technology, employees can also
undergo practical training that can be conducted and repeated at any time.
    9. Digital platforms. Digital platforms bring together two or more groups of people looking for
or offering products and services. This creates a more distributed approach where people now have
access to many options with just one click. This allows synchronizing information in real-time.
    10. Digital culture. Digital platforms in various human resource management processes have
created a new set of cultures related to the interaction of different generations. Due to the baby
boomers and the retirement of Generation X, the company's staff will mostly consist of millennials.
This group grew up with technology and understood how to use it to their advantage [22]. We propose
to consider digital culture as the main element of the overall corporate culture of the organization.
And the overall corporate culture of the organization must meet the trends of global digital culture. As
the concept of digital culture is a new social phenomenon, there is a need to use the potential of digital
transformation to integrate into the global digital culture. Given the trends in the introduction of
blockchain technology in various fields of activity [23], the acquisition by HR specialists of skills in
modern digital technologies becomes a necessary and sufficient condition for successful operation.
    11. Introduction of quarantine restrictions. The introduction of quarantine restrictions transforms
approaches to work organization, work regimes, stimulates the growth of remote workers and
freelancers. Technological and technical support of these phenomena requires the use of modern
digital technologies in personnel management.
    Therefore, making digital decisions for human resource management processes is very important
for the organization, because they provide many benefits to reduce the number of unnecessary or
repetitive tasks, reduce the risk of errors and allow to focus on critical tasks. There is a common
misconception that digitalization is difficult to accept, but these eleven areas can be an incentive to
reduce the entry barrier into the use of digital technologies in personnel management. To confirm the
influence of these stimulants, we researched the labor market of HR professionals [23].

5. Results
    The dynamics of the number of vacancies of HR specialists in January 2020 – October 2021 (Fig.
1) is characterized by a growing trend until June 2021 in the study period. The formed trend began to
reproduce (grow) from July 2021 to October 2021. This can be partly explained by: employment of
graduates of higher education institutions with a bachelor's and master's degree, who have a
specialized education; established traditions of remote work with the use of modern digital
technologies (messengers, promotion of virtual offices, planners (for example, "Jira"), and other
applications that facilitate the rhythm of remote work and control over its implementation). Such
traditions are explained by long-term quarantine restrictions; reduction in the number of jobs due to
the pandemic, especially in the field of small and medium-sized businesses.
    To study and identify the main trends in the dynamics of vacancies, it is necessary to use a tool
that will allow multidimensional analysis. Taxonomic analysis can serve as such a tool [16]. The
versatility of this method allows it to be used to analyze the properties of one unit, which is
characterized by the values of the features given in the form of time series.

Figure 1: Dynamics of the number of vacancies of HRM specialists (by professional composition) in
January 2020 - October 2021
    This statement of the problem allows us to obtain a general picture of the dynamics of the labor
market as a whole in the study period (January 2020 – October 2021). And this, in turn, allows us to
see the imbalances that occur in the labor market in a consolidated form. Using taxonomic analysis, it
is possible to compile multidimensional statistical material related to the labor market and obtain a
generalized description of the state of the labor market of HR professionals based on the methodology
(Table 1). These trends in vacancies (according to the professional composition of the field of HR
specialists) are roughly consistent, but not unambiguous, they are not completely symmetrical, but the
taxonomy allows us to see the general trends in the need for HR professionals in the labor market.
    The results of the calculation of the taxonomic indicator of HRM vacancies between January 2020
and October 2021 are shown in the figure (Fig. 2). The dynamics of this indicator are unstable, the
lowest value in 2020 is observed in January, and in 2021 the lowest value is observed in July. The
maximum values in 2020 are observed in December (Ki=0,36), and in 2021 in October (Ki=0,99).
This can be explained by the shortage of specialists who possess sufficient information technology
skills, i.e., the demands of employers and, accordingly, the qualification requirements for such
specialists have changed rapidly.

Figure 2: Dynamics of taxonomic indicators of HRM vacancies in January 2020 – October 2021

    The dynamics of the number of unemployed from January 2020 to October 2021 have significant
fluctuations (Fig. 3). Thus, from January 2020 to December 2020 there was a general increase in the
number of unemployed. In January 2021 there was a significant reduction in the number of
unemployed, which is partly due to: legislative regulation in the field of employment (for example,
change of retirement age and the possibility of early retirement); professional development, in
particular the acquisition of the necessary skills in the field of information technology, which,
although not sufficient, is due to the activity of the state employment service [23]. Most of the
unemployed in the field of HR professionals are women over 55 years of age.

Figure 3: Dynamics of the number of registered unemployed HR specialists (by professional
composition) in January 2020 – October 2021

   To substantiate the relevant unemployment trends of HR professionals by professional
composition, it is also necessary to make an integrated assessment using the methods of
multidimensional analysis (Fig. 4). The dynamics of the taxonomic unemployment indicator is
characterized by instability, as well as the dynamics of the taxonomic vacancy indicator for the study
period. Thus, the lowest value in 2020 is observed in December, and in 2021 in July. The maximum
values in 2020 are observed in January (Ki = 0,67), and in 2021 also in January (Ki = 1,00). This can
be explained by the redundancy of specialists who do not have enough information technology, i.e.,
do not meet the needs of employers. By imposing the 2 graphical representations of taxonomic
indicators (unemployed and vacancies), it is possible to visually assess the degree of balance of the
labor market of HR professionals (Fig. 5).

Figure 5: Dynamics of the degree of balance of the labor market of HR specialists in January 2020 -
October 2021
   The balance of the labor market in terms of taxonomic indicators of vacancies and the number of
unemployed took place in the third quarter (June, July, and August) of 2021. Instead, the most
unbalanced market was in the first quarter (January, February, March) in 2020 and in January 2021.
The degree of balance is assessed by calculating the distances between the value of the taxonomic
indicator of vacancies and unemployment in the period.
   Our research compared the dynamics of taxonomic indicators of HR vacancies and dynamics of
taxonomic indicators of unemployed HR specialists is one of the areas of using Data Mining tools in
the sphere of labor market research.

6. Discussion
   The results obtained in this research are confirmed by trusted sources in the field of HRM
practices:
   1. Experts of the Ukrainian Association HRPro [24] emphasize that digital skills are becoming not
only a tool but also a philosophy in the activities of HR professionals. Digitalization, according to
experts, is a driving force in harmonizing and balancing the labor market.
   2. The editorial board of the magazine "TOP-100. Ratings of the largest" [25] conduct the
traditional rating of the best HR directors according to a certain set of characteristics. The expert jury
and editorial board of the publication selected 30 finalists from more than 150 participating
companies. Each participant of the rating is evaluated by experts with the help of special
questionnaires, which are sent to them after the final formation of the long list of the rating. In
determining the finalists of the rating, several special criteria are taken into account, including
automation and gamification of HR processes in the activities of the companies from which they are
nominated;
   3. According to the results of research [25], every year the relevance of information technology
skills in professional activities is growing. Therefore, the goals and program learning outcomes of HR
graduates should be reviewed following the requirements of specialty development and employers.
   It is concluded that several factors, in particular, quarantine restrictions; general development of
information technologies, and digital transformation of the national economy have created conditions
that balanced the indicators of vacancies and unemployment in the labor market.
   In the article [17] the author focuses on studying the demand for different categories of IT
specialists rather than assessing the balance with the corresponding supply in the labor market. The
practical application of the proposals submitted by the author, in our opinion, is very fundamental but
limited only by the situation in the labor market and IT specialists. We agree that the vast majority of
highly specialized segments of the labor market require separate and specific studies that would
consider industry specifics.
   The results we obtained during the research are confirmed by HRM experts. Experts believe that
the possession of relevant digital competencies for employees in this field is a necessary condition for
the formation of the labor market of HR professionals. Prospects for the development of the labor
market of HR professionals should be based on following the principle of lifelong learning. To adjust
the activities of the State Employment Service of Ukraine, including ensuring proper retraining of
unemployed HR professionals following modern labor market requirements, it is considered
expedient to take into account such factors as stimulants, results of monitoring the degree of labor
market balance, and expert judgments.

7. Conclusions
    This research on the impact of digital technologies on the labor market of HR professionals has
allowed:
    1. To study digital trends in the creation of new operational processes in personnel management;
    2. Substantiate the conditions for the implementation of digital technologies, including ensuring
the appropriate level of digital competence;
    3. Determine the content of the main stimulants that contribute to the implementation of digital
technologies in personnel management. These include greening of approaches in the organization of
work of HR specialists; the emergence of applications that promote greater independence of
employees; automation of routine processes of personnel record keeping; recruitment through social
networks; virtual reality (VR) to train and ensure the appropriate level of moral and psychological
climate in the team; gamification in work; study the needs of employees; lifelong learning; digital
platforms; digital culture; introduction of quarantine restrictions. The research emphasizes that it is
advisable to consider digital culture as the basis of the corporate culture of the organization, which
should meet the trends of global digital culture. Thus, it is a new social phenomenon that in some way
determines the digital transformation and will allow harmonious integration into the global digital
culture;
    4. Use the technology of statistical methods, Data Mining that allows scaling the variability of the
labor market of HR specialists, i.e., to reduce to a specific scale.
    5. Assess the impact of these stimulants by studying the market of HR professionals. This research
was based on an array of official statistics. Since the traditional processing of statistical data does not
allow to assess the state of the labor market as a whole, the method of taxonomy was used, which
determined the degree of balance in the labor market of HR professionals in Ukraine in January 2020
– October 2021. Comparing the values of taxonomic indicators of HRM vacancies and the
unemployed indicates significant distortions in the labor market from January 2020 - to October 2021.
This trend is partly due to the influence of unlikely random factors but with substantial consequences.
    In our opinion, the proposed approach is a useful tool for monitoring the situation in the labor
market of specialists in the field as a whole.
