## Body

## 1. Introduction

Information technology, which is characterized by electronization, digitalization, and networking, has advanced quickly throughout the world since the turn of the twenty-first century. Information technology has already impacted a number of areas, including the economy and society, changing the political, social, cultural, and economic landscape of the world [1]. One of the key indicators of a nation’s overall strength and ability to compete internationally is the level of development of its information technology sector. Enterprises operate in a setting where there are many opportunities for growth and unheard-of levels of fierce market competition [2]. The key is having speed and efficiency if an enterprise wants to endure and grow in the increasingly fierce market competition. As a result, the most valuable resource in this type of enterprise is needed at a higher level because they are the ones who create and transmit knowledge. The organizational structure and development strategies of businesses have changed significantly in recent years, and many have elevated HRM (human resource management) to a strategic level, making HR (human resources) a crucial component in developing strategies and ensuring their implementation. A significant amount of HR data are produced in the routine operations of businesses as enterprise information technology adoption continues to grow. However, the majority of users perform some basic, incomplete, and shallow queries on the available data and do not perform in-depth analyses of these data. It is objectively necessary for the statistical department to provide high-quality statistical data and information in order to increase the decision’s scientific rigor. Enhancing the quality of integrated statistical data is a key strategy for achieving the goal of contemporary service-oriented integrated statistics. High-quality results can only be achieved with high-quality data. It is urgent to carry out HRM from a strategic height, and its HR strategy must be compatible with the strategic development of enterprises in order to compete in the increasingly fierce global talent market. The degree of enterprise management modernization and the ability of enterprise managers to make quick, informed decisions are both directly related to an organization’s ability to survive. AI (artificial intelligence) [3, 4] was developed to address the issue of “excessive data and poor knowledge.” Applying current AI to the HRM of the enterprise is necessary to realize that HR can drive the development of the enterprise and to make the enterprise’s manpower reserve work to achieve a qualitative leap and innovation.AI fully utilizes the concepts, techniques, and resources of other fields, particularly computer science knowledge such as database technology and data analysis [5]. It can manage more types of data, including text, images, sounds, and more, in addition to a greater volume of data. The current business procedures, service philosophies, and economic models are improved on the basis of AI. For the development of the nation and businesses, AI is cited as a key strategic resource. More and more company managers, including decision-makers in the telecom, finance, retail, insurance, and other industries, are becoming aware of AI-business intelligence [6]. The highest priority for information technology development in these sectors is now AI-business intelligence. One of them, DM (Data mining) technology, does not require a background in statistics and can better serve user needs using focused computer software analysis, making it more applicable in real-world settings. Its unique human resources and intellectual capital are the main factors that influence an enterprise’s competitiveness. The survival and growth of businesses are directly correlated with these two variables. The HRM function has grown in importance and has been promoted from the tactical to the strategic levels of the enterprise after managers came to understand the value of HR [7]. The majority of businesses have started to understand that employee quality and morale are now essential for an organization’s survival and growth in all business processes, including product design, production, sales, and service. A company’s human resources will play a key role in determining its enterprise strategy if they are distinctive [8]. All industries have set up ideal HRM systems and amassed a wealth of valuable data as a result of the advancement of information technology and modern enterprise management methods. However, at this time, HRM systems remain at the level of management information systems with extensive functions, and they do not fully rely on historical data to learn new things, particularly because they have not been successful in performing the desired function of aiding decision analysis [9]. A new discussion point for businesses and society is how to handle the opportunities and difficulties brought on by AI. This article proposes an AI-based system for HR data integration based on a thorough analysis of pertinent literature and discussion. This article makes the following innovations:(1)
This article summarizes the development and research status of AI and enterprise HRM and analyzes HRM problems from the aspects of management idea, management method, and management content. In addition, the construction principle, process, and model types of HR data integration model base are determined. On this basis, the method of establishing HR data integration system with a simple modeling process, easy solution, high prediction accuracy, verifiability, and correction is determined. The research shows that the system has certain superior performance and convenient operation.(2)
Aiming at the low integration level of HR raw data, this article proposes an HR data integration system based on a hidden semantic model. It makes predictions and analyses according to HR information and provides a decision-making basis for enterprise personnel recruitment and employee training. At the same time, aiming at data problems, data standardization, conversion, cleaning, and other technologies will be adopted to improve data quality and DM and the corresponding mining topics to improve the credibility and quality of mining.


## 2. Related Work

AI is a brand-new technology that permeates all facets of life and is built on a foundation of big data. There is little research on the use of AI in the fields of human resources and economic management. Related scholars have focused a lot of their research on the use of AI in the technical field.Martin researched and analyzed the dilemma of enterprise HRM in the information age and put forward specific measures for innovation and development, providing a reference for enterprise development [10]. Davda et al. used the dispersion maximization multiattribute decision-making method, which can comprehensively consider the cost factors and weights of various decisions and can sort each decision. They proposed a competency-based HR quality evaluation model [11]. Popaitoon and Siengthai established a DM application system based on the existing HRM system, designed a DM application system, and realized and verified some mining functions [12]. King conducted a more in-depth analysis and research on the HR planning model based on corporate strategy, planning scheme design, how to implement this concept, and how to apply it to the actual enterprise [7]. Combined with the impact of big data on HRM, Shet et al. explored the specific application of big data in future HRM so as to achieve timely adaption of HRM in the era of big data [13]. After studying human data management, Tambe believed that digital HRM will become the main development direction in the future. The level of organizational management ability and company information determines the ability to compete in the future. Compared with traditional HRM, the database-based management model has more goals and has a positive impact on the performance of organizational employees and promotes the improvement of organizational efficiency [14]. On the basis of the lack of existing HRM risk research, Stone and Deadrick revealed the risk incentives of HRM from the seven management links of poststructure design, recruitment screening, employee training, performance appraisal, salary management, career development design, and cultural incentives, quantify the indicators, and finally form a more scientific early warning system of risk incentives [15]. Taderera et al., based on the resource-based enterprise view paradigm, compared strategic HRM theories under different strategic paradigms to have a deeper understanding of the strategic HRM theory based on the resource-based enterprise view [16]. With AI as the background, Liu conducted research on the intelligent transformation of a group’s HR sharing center. The research on the transformation of its HR sharing center can provide a successful model and reference for the construction and transformation of HR sharing centers in other enterprises and can also enrich the theory of HR sharing centers [17].An artificial intelligence-based system for integrating human resource data is presented in this article. The basis for the HR data integration model base is established in this article, along with its construction principle, process, and model types. Based on this, a method for creating an HR data integration system with a straightforward modeling process, an easy solution, and high prediction accuracy, verifiability, and correction is chosen. In addition, technologies for data standardization, conversion, cleaning, and other issues are used to enhance the quality of the data and DM, the pertinent mining topics to raise the stature and standard of mining. The study demonstrates the system’s exceptional performance and practical use.


## 3. Methodology

### 3.1. HRM and Data Integration

The competition in the new economic era is knowledge-based, and since human resources are the carriers of knowledge, they inevitably become the focal point of the competition among businesses in the new economy. Changing the focus of market competition from the competition of physical and chemical resources, such as capital and products, to the competition of intellectual resources is a key aspect of the knowledge economy [18]. With the rapid advancement of business management and information technology, HRM information systems tailored to HRM have emerged as a crucial tool for businesses looking to attract, retain, and motivate HR, integrate other resources into their operations, and gain a competitive edge. Nowadays, businesses compete primarily for talent, and the emphasis of market competition shifts from the competition for material resources like money and goods to the competition for intellectual resources. Enhancing an organization’s internal and external environments, streamlining business operations, and boosting competitiveness are all directly impacted by effective HRM and development. In this way, the efficiency of HR efforts within an organization has evolved into a strategic element to support organizational growth. Applying current AI to the enterprise’s HRM is required in order to realize that HR can drive the development of the business and make the enterprise’s manpower reserve work to achieve a qualitative leap and innovation. Because of this, many businesses see the resolution of the manpower issue as a crucial sign of their success. Enterprise HRM personnel must be equipped with a full suite of decision-making tools that support enterprise HRM, work with businesses to manage and develop strategic HR, and support their strategic and tactical goals with excellent human resources, teams, and organizational structures in order for businesses to grow. HR planning is the foundation for many HRM initiatives. It is a crucial HRM task to ensure that there is a demand for HR in the strategic implementation by predicting enterprise supply and demand in various historical eras, social contexts, and developmental stages developing corresponding policies and measures.The traditional HR department is overworked with mundane transactional work, which results in low efficiency, disconnect from the business system, and inability to quickly gain insight into the corporate strategy. The senior managers of businesses must therefore reconsider the HR function. In addition, a system for integrating HR data should be developed, and transactional HR basic services should be centralized, standardized, and focused. In order to guarantee the implementation of enterprise strategy, HR planning is a crucial HR task that involves forecasting and analyzing the quantity, quality, and structure of HR across various historical eras, social contexts, and developmental stages. Its goal is to prevent unnecessary costs brought on by layoffs of staff in addition to ensuring the enterprise’s need for HR during the implementation of the strategy and making sure that the supply and demand of HR are dynamically balanced in the day-to-day activities of the company. HRM is a vital component of and a solid assurance for an enterprise’s survival, innovation, and growth, all of which are directly related to achieving the enterprise’s strategic development goals. Enterprise HRM activities, however, could at any time be exposed to a variety of risks given the fast-changing internal and external environments of today. The main goal of strategic HRM is to ensure that organizations have the right people at the right times to achieve their goals. HR planning does this by forecasting future staff demand for businesses, analyzing current staff supply, and developing policies and planning measures. The development of HR planning must be based on the enterprise strategy, provide HR support for achieving the enterprise’s strategic development goals, and aim to achieve the enterprise’s strategic goals. To meet their objectives for strategic development, businesses must effectively implement HR. It is a science and technology that people will enable them to manipulate machines to perform a wide range of tasks and realize cognitive, analytic, and other functions. AI is a broad category that encompasses many disciplines. Cognition, perception, and calculation are the three main components of its technical intelligence. Many intelligent work and lifestyles, including online, self-help, and remote services, have emerged due to the development and application of AI, the Internet, and other new technologies. This has also challenged the traditional HR sharing centers’ many repetitive and ineffective services. In this sense, information technology not only makes it possible for businesses to get the information they require but also encourages them to reuse that information. The objective of implementing business intelligence is to fully utilize the vast quantities of quantitative data that organizations collect through regular business operations, integrate and analyze them, and then transform them into knowledge and information to support organizational decision-making. AI is a valuable resource for the business, and it gives it a new chance to boost its level of innovation and personnel management.To meet the design requirements of HR data integration system, it is necessary to complete the design of a data integration and recommendation system [19] based on the construction of a data warehouse. The structure of the HR data integration system based on AI is shown in Figure 1.Figure 1
HR data integration system structure based on AI.With the changes of Industry 4.0 and the Internet of Things, the sharing economy is booming as a new economic form. Through the integration and utilization of excess capacity and idle resources, enterprises set up sharing platforms such as technology, finance, and HR, so as to realize the scale benefit of user sharing and win-win. In the era of the knowledge economy, HR, as the primary resource of an enterprise, plays an increasingly important role in the enterprise, which is related to the future development of the enterprise and the realization of its strategic goals. However, at present, the HRM ability of most enterprises is weak, and the overall competitiveness of HR is low. There is a complementary relationship between business intelligence and HRM system. HRM system provides valuable historical data for business intelligence, while business intelligence based on HRM system can provide enterprises with tools to access, report, and analyze information, which can improve the analysis ability of enterprises and reduce the cost of information technology. Enterprise strategy is a strategic plan, which is formulated by enterprise managers on the basis of a full analysis of the internal and external environment of the enterprise in order to maintain or gain a competitive advantage. The realization of the strategic objectives of an enterprise needs the support of various resources, the core of which is the HR of the enterprise. The HR system is constantly changing in the direction of digital informatization, and the optimization of organizational structure and the rational allocation of personnel mark the way for enterprises to upgrade and transform. In this process, if HRM within the enterprise cannot keep pace with the development in time so as to meet the new strategic objectives of the enterprise, then it will be difficult for us to reap the benefits and convenience brought by technological development. Business intelligence is mainly applied to customer relationship management and supply chain management in enterprises. From the perspective of data analysis, business intelligence is a process of collecting, analyzing, and processing high-quality and valuable information by using various information systems to solve various problems encountered in business activities. Its basic functions include personalized information analysis, forecasting development trends, and assisting decision-making. From the application perspective, business intelligence helps users conduct online analytical processing and data analysis on business data, help solve business problems, predict development trends, and assist in decision-making, to better achieve business objectives [20].


### 3.2. Construction of HR Data Integration System Based on AI

The competition between businesses is more fierce in the modern world, and human resources have developed into a crucial resource for the growth of businesses. Businesses have gradually come to understand its significance and raised it to an unprecedented level. HR is complicated for businesses, so we need to organize and integrate it. Therefore, HRM combines the company’s characteristics, creates the long-term goal for the company, ensures its sustainable growth, and enables every employee to fully utilize their own advantages. Human resource management (HRM) is a systematic project that includes various elements, including poststructure design, recruitment of personnel, training of staff, performance evaluation, salary management, career development, and cultural motivation. An AI-based system for integrating HR data is built in this section. The integrated feature vectors of recruitment positions and job seekers can be fused using the hidden semantic model based on user behavior to produce the fused implicit features. It is impossible to determine whether the positions are matched with job seekers directly because users on the HR platform are segmented based on the types of behaviors they exhibit. To get the final recommendation, it is then necessary to combine the deep forest and the hidden semantic model while taking the user’s interest and job compatibility into account. The recommended workflow of the system is shown in Figure2.Figure 2
System recommended work flowchart.In this paper, each level of the system has a different functional emphasis, and at the same time, it provides services for the upper level, thus avoiding the repeated definition of functions. This makes the understanding and analysis of functions more clear in implementation, it is easy to add new content at relevant levels, and the implementation efficiency is also relatively high. The application layer of this system is mainly composed of a user management board, job browsing board, inquiry board, and recommendation board, which is mainly responsible for receiving and processing user requests. The collected data can be classified into two categories: unstructured and structured data. Unstructured data, as its name implies, big data can express its nature in various forms. Its common forms are as follows: images, audio, XML files, videos, HTML files, and desktop documents. The other kind of structured data is very conventional data, usually stored in a two-dimensional data table. The data cache stores the latest job data, user status, and related hot jobs; the data warehouse mainly stores recommended positions, and user behaviors. The database mainly stores registration and login information, as well as related results of job recommendations. Data processing generally refers to the related processing of metadata, including data quality management and standard management. Metadata integration refers to integrating data into a unified data view and transforming data from different data sources into a new data source. In this case, data transformation refers to the transformation of data from one formal framework to another. The preprocessed data will be integrated according to related topics to form a thematic data layer that directly refers to the mining application layer.According to the latent semantic model, the number of hidden classes isF, then the calculation formula of job seeker u′s prediction score for recruitment position i is as follows:(1)rui=∑k=1Fpukqki.MatrixP and matrix Q can be solved according to the optimization loss function. In this process, a penalty factor is added to avoid overfitting problems:(2)λ∑upu2+λ∑ipi2.Then the loss function calculation formula is as follows:(3)c=∑u,irui−∑k=1Fpukqkiλ∑upu2+λ∑ipi2.According to the loss function, the random gradient descent method is used to minimize the root mean square error between the job seeker’s real score and the predicted score, so as to optimize the objective function. Find the partial derivative of the objective function:(4)∂Cpuk=−2rui−∑k=1Fpukqkiqki+2λpuk,∂C∂puk=−2rui−∑k=1Fpukqkipuk+2λpki.The objective function is optimized by stochastic gradient descent. Assuming that the step size in this process isα, the recursive formula is as follows:(5)puk=puk+αrui−r^uiqki−λpuk,pki=pki+αrui−r^uiquk−λpki.In order to better input data, smoothly connect research objects and models, and speed up the convergence of the learning and training network, before inputting data, all sample data are normalized in this article. All of them are converted into dimensionless index values of [0, 1] closed interval, thus eliminating the problem of fuzzy results caused by different index properties and nonsuperposition. In this article, based on the principle of reflecting the differentiation of research objects as much as possible, that is, maximizing the sum of squares of deviation, the range processing method is used to normalize the indexes. For the index with maximal nature, the processing function selected for normalization is as follows:(6)xij′=xij−mjMj−mj.For indexes with minimal properties, the processing function selected for normalization is as follows:(7)xij′=Mj−xijMj−mj,Mj=maxxij,mj=minxij.Among them,xij is the data of each sample; xij∈0,1 is the dimensionless index after normalization.Whether the predicted value of the model is credible or not must be tested according to certain procedures and ways. The posterior error test is a test of statistical characteristics of residual distribution, and the variance ratio and small error probability are constructed to test the model. The specific steps are as follows. Average prediction error is as follows:(8)q¯=1n−1∑k=2nqk.Average of raw data is as follows:(9)x¯=1n∑k=1nx0k.Standard deviation of raw data is as follows:(10)S1=1n∑k=1nx0k−x¯2.Standard deviation of prediction error is as follows:(11)S2=1n−1∑k=2nqk−q¯2.The greater the user’s interest in a position, the higher the matching degree, and the higher the recommended value. This shows that the algorithm is trying to recommend jobs with high matching degree to users.The database primarily holds data on employees, including their names, salaries, insurance coverage, and attendance, as well as necessary data dictionaries, error correction tables, and tax rate tables. The data table primarily keeps track of employees’ fundamental details, including the qualities required by the statistics bureau. Each month, each employee’s salary items are recorded in the employee payroll. Information that is internal to the company includes, among other things, basic information about current employees, basic information about departing employees, dynamic information about employees’ work, and reserve information about enterprise talents. Businesses can fully understand the information dynamics of HR by analyzing these data. The external information of an enterprise includes, among other things, the flow of talent within a given industry, the supply and demand for talent within that industry, the supply and demand, and salary information across the board. By examining this external data, the business can forecast the flow of talent and potential reasons for employee departures at any time, allowing it to take targeted action in advance. Data collection, data selection, data cleaning, data integration, and metadata creation are among the fundamental duties of the system data layer that must be performed in order to process data effectively. The system is created to integrate the operations related to a specific management object in the same window for the convenience of use, making the system consistent in function design and operation mode.

Average prediction error is as follows:(8)q¯=1n−1∑k=2nqk.Average of raw data is as follows:(9)x¯=1n∑k=1nx0k.Standard deviation of raw data is as follows:(10)S1=1n∑k=1nx0k−x¯2.Standard deviation of prediction error is as follows:(11)S2=1n−1∑k=2nqk−q¯2.The greater the user’s interest in a position, the higher the matching degree, and the higher the recommended value. This shows that the algorithm is trying to recommend jobs with high matching degree to users.The database primarily holds data on employees, including their names, salaries, insurance coverage, and attendance, as well as necessary data dictionaries, error correction tables, and tax rate tables. The data table primarily keeps track of employees’ fundamental details, including the qualities required by the statistics bureau. Each month, each employee’s salary items are recorded in the employee payroll. Information that is internal to the company includes, among other things, basic information about current employees, basic information about departing employees, dynamic information about employees’ work, and reserve information about enterprise talents. Businesses can fully understand the information dynamics of HR by analyzing these data. The external information of an enterprise includes, among other things, the flow of talent within a given industry, the supply and demand for talent within that industry, the supply and demand, and salary information across the board. By examining this external data, the business can forecast the flow of talent and potential reasons for employee departures at any time, allowing it to take targeted action in advance. Data collection, data selection, data cleaning, data integration, and metadata creation are among the fundamental duties of the system data layer that must be performed in order to process data effectively. The system is created to integrate the operations related to a specific management object in the same window for the convenience of use, making the system consistent in function design and operation mode.


## 4. Result Analysis and Discussion

Firstly, the system collects data related to the mining topic, then generalizes the detailed data by concept stratification, fills the vacancy value with the average value of attributes, and then deletes redundant or inconsistent data. Before training the network, the weights and thresholds of the network must be initialized, and the learning rate, target precision control parameters, etc. must be determined. Take a random number with the initial weight between [−1, 1] and set the learning rate to 0.01; after training, the target precision control parameter of the network is set to 0.0006; both the sample pattern calculator and the training times calculator take the value of 1, and the error value is 0. Real data are used to evaluate the performance of the proposed algorithm model, and experiments and analyses are carried out. The data collected from the HR employment platform is integrated into a dataset, and after a series of processing work, a data warehouse suitable for HR recommendations can be obtained. At the same time, Python is used to extract the data. The system test environment of this section is shown in Table1.Table 1

The prediction effect of this network model will be inadequate if sample data are not sufficiently representative, numerous samples contradict one another, or there are issues with data normalization. As a result, the original data must be preprocessed in order to achieve an accurate match between job seekers and positions. The precise processing procedures involve the following three steps: data extraction, data cleaning and conversion, and data loading. The first step in preprocessing statistical data is to remove any data objects that are inaccurate, void, or inconsistent with the actual situation. Following data preprocessing, it is necessary to standardize attribute values, filter out noise, and transform the data completely into the format required by the algorithm used in this article in order to eliminate these influences. Each numeric type has its attribute value normalized to an interval within a unified space. In order to understand the change in the model performance caused by the fused features, the situation of deep forest input before and after introducing implicit features was compared. The result of the recall rate is shown in Figure3. The result of the F1 value is shown in Figure 4.Figure 3
Recall results before and after introducing implicit features.Figure 4
F1 value results before and after introducing implicit features.As can be seen from Figure4, the model based on explicit features is lower than the recommended recall rate and the average ratio of F1 value of deep forest with implicit features. This result proves that the implicit features of users-posts increase the feature information of the input data of the model; at the same time, the recommendation performance of the model has also been improved. The system will test the efficiency of HR data integration and get the results as shown in Figure 5.Figure 5
Efficiency results of HR data integration by the system.Experiments show that the efficiency of HR data integration of this system can reach 96.37%, and its efficiency is at a high level. In this paper, the system has a good specification for data. At the same time, before the data analysis and application, it also organizes the data related to the topic and simply processes the “dirty” data and noise data. Based on the actual HR statistical data, the statistical anomaly detection module can find the anomaly data in HR statistical data by applying the detection method proposed in this article. This function can improve the convenience of enterprises and institutions in reporting statistical reports and improve the management efficiency of enterprises and institutions themselves. The system stability test is shown in Figure6.Figure 6
System stability results.It can be seen that the stability of this system can reach 95.84% at the highest. The system has certain superior performance and convenient operation. Information classification accuracy of different algorithms is shown in Table2.Table 2

At the same time, when using knowledge for decision support, different colors are used to indicate the knowledge used in decision-making, which can more directly and objectively represent the decision support process. In addition, the HR data integration system in this paper provides multilevel page menus and flexible operation modes for end users, which constitutes a friendly man-machine interface and improves the transparency of the system. It can better realize the integration and mining of HR data and provide convenient services for related work. To test whether the performance of the hybrid recommendation algorithm is improved, the performance of three algorithms based on deep forest, hidden semantic model, and hybrid recommendation is compared, and the results are shown in Figure7.Figure 7
Performance comparison of different recommendation algorithms.From the experimental results, it is not difficult to see that the recall rate and F1 value of a single deep forest and hidden semantic model are obviously lower than those of the hybrid recommendation algorithm, which proves that the hybrid recommendation algorithm integrates the advantages of the two models, thus improving the recommendation performance of the algorithm. Therefore, the deep forest plays a decisive role in the performance of the hybrid recommendation algorithm, and the hidden semantic model plays a supplementary role. Experiments in this chapter show that the efficiency of HR data integration in this system can reach 96.37%, and the stability of this system can reach 95.84% at the highest. The system has certain superior performance and convenient operation. It can better realize the integration and mining of HR data and provide convenient services for related work.


## 5. Conclusions

Human resources (HR), the main resource of businesses in the knowledge economy, are becoming more and more crucial to businesses. Businesses gradually came to understand its significance and role, and they elevated it to a previously unheard-of level. When it comes to the achievement of an organization’s strategic development goals, HRM serves as the foundational support and a solid assurance for its continued existence, innovation, and growth. However, AI, a ground-breaking technology, demonstrates “human wisdom” more and more frequently. Its ongoing innovation and application across a variety of industries have boosted society’s overall economic gains and sped up social development. The status of AI research and development in relation to enterprise HRM is summarized in this article, which also examines HRM issues from the perspectives of management concept, management method, and management content. The HR data integration system based on a hidden semantic model is suggested in this article in order to address the low level of integration of HR raw data. It makes predictions and analyses based on HR data and provides a basis for decision-making for hiring and training employees in the enterprise. Studies reveal that this system’s stability can reach 95.84 percent at its highest level and that it can integrate HR data with an efficiency of 96.37 percent. In terms of performance, the system is undoubtedly superior and simple to use. In addition to offering practical services for related work, it can more effectively realize the integration and mining of HR data. There are still some flaws in this study, despite the fact that it conducts a reasonably thorough investigation into HR data integration. Additional system expansion and development are still required. The following step is to determine the necessary HR quality requirements and characteristics in practice, taking into account the HR situation and post characteristics of a specific enterprise. The subsequent study should improve the effectiveness and usage of the HR data integration system.
