[0015] In order to make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions of the present invention in conjunction with the embodiments. Obviously, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.

[0016] Currently, the existing book procurement method mainly adopts manual determination of book procurement orders according to actual requirements such as book procurement budgets, book types, book prices, the number of copies to be purchased, and existing library collections. However, this method mainly relies on the subjective judgment of procurement personnel based on experience to determine the content of book procurement orders. Sometimes, there is a large deviation between the actually purchased books and the readers' needs. That is, the existing book procurement method mainly has problems of low efficiency and poor accuracy in determining the content of book procurement orders.

[0017] Based on this, the present invention provides a method, device and electronic equipment for regulating and controlling book purchases based on borrowing data, which can alleviate the above-mentioned problems existing in the related art.

[0018] To facilitate understanding of this embodiment, firstly, a method for regulating and controlling book purchase based on borrowing data disclosed in an embodiment of the present invention is described in detail. Figure 1 As shown, the method may include the following steps:

[0019] Step S102, based on the primary and secondary school library regulations and the collection data of the target library, an initial book purchase list of the target library is generated.

[0020] Step S104, classify and store the borrowing data corresponding to different data sources of the target library into the target database, so as to associate and store the borrowing data of the same book through the target database.

[0021] The borrowing data of each book in the target database may be bound with corresponding classification information.

[0022] Step S106, acquiring the attribute information and preference data of the reader, and determining the target book based on the borrowing data and classification information in the target database as well as the attribute information and preference data.

[0023] Among them, the attribute information may include the reader's age, gender, grade, etc., and the preference data may include the reader's borrowing behavior data, questionnaire data, etc.

[0024] Step S108, determining the purchase quantity of the target book based on the target borrowing data and target classification information of the target book in the target database and the collection data, and updating the initial book purchase list based on the purchase quantity of the target book.

[0025] An embodiment of the present invention provides a book purchasing and control method based on borrowing data. The method first generates an initial book purchasing list of a target library based on the regulations of primary and secondary school libraries and the collection data of the target library. The borrowing data of the target library corresponding to different data sources are classified and stored in a target database so as to associate and store the borrowing data of the same book through the target database. The borrowing data of each book in the target database is respectively bound with corresponding classification information. The attribute information and preference data of the reader are then obtained, and the target book is determined based on the borrowing data and classification information as well as the attribute information and preference data in the target database. The number of purchased copies of the target book is then determined based on the target borrowing data and target classification information and collection data of the target book in the target database. Finally, the initial book purchasing list is updated based on the number of purchased copies of the target book. By using the above technology, after obtaining the initial book purchase list, the borrowing data from different data sources can be integrated into the target database for storage, so that the initial book purchase list can be updated later using the reader's attribute information and preference data as well as the collection data and the data in the target database, thereby optimizing the book purchase strategy, improving the efficiency and accuracy of book purchases, and helping primary and secondary school libraries meet the requirements of relevant library regulations for primary and secondary schools.

[0026] As a possible implementation, determining the target book based on the borrowing data and classification information as well as the attribute information and preference data in the target database in the above step S106 may include:

[0027] Step A1: perform analysis based on the borrowing data and classification information in the target database.

[0028] The analysis results may include the borrowing indicators of each book within a preset borrowing period and the trend of borrowing data over time.

[0029] Exemplarily, the operation method of the above step A1 can be: using the borrowing data and classification information in the target database to count the borrowing indicators of each book within a preset borrowing period; wherein the borrowing indicators may include borrowing frequency, renewal rate, reservation quantity, timely return rate, reader rating, etc.; based on the borrowing data and classification information in the target database, a borrowing trend analysis is performed; wherein the borrowing trend analysis result can characterize the trend of borrowing data bound to the classification information over time.

[0030] Step A2, determining the reader's borrowing preference based on the borrowing data bound with the classification information and the reader's attribute information and preference data, and determining the target book based on the analysis result and the borrowing preference.

[0031] Exemplarily, after classifying and storing the borrowing data in the target database, the borrowing preferences of different reader groups can be analyzed by combining the attribute information such as the age, gender, and grade of the readers, as well as the preference data such as the borrowing behavior data and questionnaire survey data of the readers. For example, it is found that primary school students are more inclined to borrow comic books, while middle school students are more interested in science fiction books.

[0032] Exemplarily, the target books can include popular books, unpopular books, and books with emerging demands. The steps A2 of determining the target books based on the analysis results and borrowing preferences may include the following steps A21 to A22:

[0033] Step A21, determine the popular books and unpopular books based on the borrowing indicators of each book within a preset borrowing period.

[0034] Exemplarily, the popular books can be found by counting the borrowing times of each book; specifically, a time period (such as one month, one quarter, or one year) can be set, the borrowing times of each book within this period are calculated, and the borrowing times of the same type of books within this period are compared. Furthermore, the books with more borrowing times within this period among the same type of books (such as: the borrowing times exceed a certain value, or the borrowing times are significantly greater than those of other books of the same type) are regarded as popular books, and the books with fewer borrowing times within this period among the same type of books (such as: the borrowing times are less than a certain value, or the borrowing times are significantly less than those of other books of the same type) are regarded as unpopular books. For example, in the past year, a certain best-selling novel has been borrowed 100 times, and the borrowing times of this book are significantly greater than those of other novels of the same type, which indicates that this book is very popular and can be considered as a popular book. Another example is that if a book has not been borrowed for more than one year, it can be considered as an unpopular book.

[0035] Step A22, determine the books with emerging demands based on the changing trend of borrowing data over time and the borrowing preferences.

[0036] Exemplarily, when it is found that the changing trend of the borrowing data (such as borrowing times, etc.) of a certain type of book shows an upward trend over time and the borrowing preference of this type of book indicates that it is popular among primary and middle school students, the relevant books in this type of book (such as new books, classic works, etc.) can be regarded as books with emerging demands. For example, it is found that the borrowing volume of books in the field of artificial intelligence begins to increase, and the existing popular books, newly published related books, classic works that discuss artificial intelligence from different perspectives, etc. in this field can be regarded as books with emerging demands to meet the growing knowledge needs of readers. The books with emerging demands can be determined based on the changing trend of borrowing data over time, borrowing preferences, and actual needs.

[0037] As a possible implementation, the preset borrowing period may include a first preset borrowing period and a second preset borrowing period, and the first preset borrowing period is less than the second preset borrowing period; based on this, the operation mode of the above step A21 may include the following steps A211 to A214:

[0038] Step A211: Determine the first borrowing scores of the books based on the first borrowing indicators of the books within the first preset borrowing period.

[0039] Among them, the first borrowing indicators may include the first borrowing frequency, the first renewal rate, the first reservation quantity, the first timely return rate, and the first reader rating.

[0040] For example, count the borrowing frequency, renewal rate, reservation quantity, timely return rate, and reader rating of a certain book in a primary and secondary school library within one month. The weights of the borrowing frequency, renewal rate, reservation quantity, timely return rate, and reader rating are w1, w2, w3, w4, and w5 respectively, and w1>w2>w3>w4>w5. Then the first borrowing score of the book = borrowing frequency × w1 + renewal rate × w2 + reservation quantity × w3 + timely return rate × w4 + reader rating × w5. In the actual application process, the values of w1, w2, w3, w4, and w5 can be preferably 0.35, 0.25, 0.2, 0.1, and 0.1 respectively.

[0041] Step A212: Determine the second borrowing scores of the books based on the second borrowing indicators of the books within the second preset borrowing period.

[0042] Among them, the second borrowing indicators may include the second borrowing frequency, the second renewal rate, the second reservation quantity, the second timely return rate, and the second reader rating.

[0043] Continuing with the previous example, count the borrowing frequency, renewal rate, reservation quantity, timely return rate, and reader rating of a certain book in a primary and secondary school library within one quarter. The weights of the borrowing frequency, renewal rate, reservation quantity, timely return rate, and reader rating are w1’, w2’, w3’, w4’, and w5’ respectively, and w1’>w2’>w3’>w4’>w5’. Then the second borrowing score of the book = borrowing frequency × w1’ + renewal rate × w2’ + reservation quantity × w3’ + timely return rate × w4’ + reader rating × w5’. In the actual application process, the values of w1’, w2’, w3’, w4’, and w5’ can be preferably 0.35, 0.25, 0.2, 0.1, and 0.1 respectively.

[0044] Step A213: Assign a first weight to the first borrowing score of each book, assign a second weight to the second borrowing score of each book, and determine the comprehensive borrowing score of each book based on the first borrowing score of each book and its first weight, and the second borrowing score of each book and its second weight.

[0045] Continuing with the previous example, after obtaining the first borrowing score and the second borrowing score of a certain book in a primary or secondary school library, a weight W1 can be assigned to the first borrowing score, and a weight W2 can be assigned to the second borrowing score, where W2 > W1. Furthermore, calculate the comprehensive borrowing score of the book = first borrowing score × W1 + second borrowing score × W2. In the actual application process, the respective values of W1 and W2 can be preferably 0.4 and 0.6.

[0046] Step A214: Determine the popular books as those with a comprehensive borrowing score greater than the first score threshold, and determine the unpopular books as those with a comprehensive borrowing score less than the second score threshold.

[0047] Among them, the first score threshold is greater than the second score threshold.

[0048] Continuing with the previous example, after obtaining the comprehensive borrowing score of a certain book in a primary or secondary school library, if the comprehensive borrowing score is greater than the first score threshold, then determine the book as a popular book; if the comprehensive borrowing score is less than the second score threshold, then determine the book as an unpopular book.

[0049] As a possible implementation manner, the collection data may include the existing number of copies of the book; based on this, the determination of the number of procurement copies of the target book based on the target borrowing data, the target classification information, and the collection data in the above step S108 may include:

[0050] Step a1: Use the target borrowing data and the target classification information to count the borrowing rate and the number of people waiting to borrow the target book within a preset time range.

[0051] Among them, the borrowing rate = the number of borrowed copies / the total number of borrowers.

[0052] Step a2: If the borrowing rate of the popular book is greater than the first borrowing rate threshold and the ratio between the number of people waiting to borrow the popular book and the existing number of copies is greater than the first threshold, then determine the first number of procurement copies of the popular book based on the preset safety factor and the borrowing rate of the popular book.

[0053] Among them, the preset safety factor is determined based on the book purchase budget and the collection capacity of the target library. In the actual application process, the preset safety factor can take values from 1.5 to 2.

[0054] Step a3, if the borrowing rate of the unpopular books is less than the second borrowing rate threshold or the ratio between the number of people waiting to borrow the unpopular books and the existing number of copies is less than the second threshold, then determine the second number of copies to be purchased for the unpopular books based on the preset safety factor and the borrowing rate of the unpopular books.

[0055] Step a4, determine the third number of copies to be purchased for the emerging demand books based on the preset safety factor and the borrowing rate of the emerging demand books.

[0056] For the sake of easy understanding, the above-mentioned method for determining the number of copies to be purchased for the target books is described exemplarily with a specific application as follows.

[0057] The borrowing rate threshold can be set in advance (such as 2 copies / person per month) to reflect the actual usage frequency of the books through the relationship between the borrowing rate of the books and the borrowing rate threshold. If the borrowing rate of a certain book in a month exceeds the borrowing rate threshold, it means that the existing number of copies of this book can no longer meet the daily circulation needs. For example, if the monthly average borrowing rate of a single copy of a book is 2 copies / person and the monthly average total number of borrowers is 10 people, then the monthly average borrowing volume of this book is 20 copies. If a month is calculated as 30 days, then this book is borrowed once every 1.5 days on average, indicating that this book is in a high-frequency usage state. The waiting number threshold can also be set in advance (such as 10 people) to reflect the actual supply and demand situation of the books through the relationship between the number of people waiting for the books and the waiting number threshold. If the monthly average reservation number of a single copy of a book exceeds 2 times the current available number of copies, it means that the monthly average supply and demand contradiction of this book is prominent. For example, if there are 3 available copies of a certain book in the library and the reservation number (i.e., the number of people waiting) of this book reaches 10 people, which is equivalent to each copy serving 3.3 people, exceeding the reasonable service number range of 2 people per copy.

[0058] To determine the supplementary number of copies of the books, the following copy increment model can be constructed:

[0059] Theoretical supplementary number of copies = (monthly average borrowing rate × monthly average total number of borrowers × average borrowing cycle) / 30 days × safety factor - existing number of copies;

[0060] Among them, the safety factor usually takes 1.5 - 2 to cope with sudden demands.

[0061] For example, the monthly average borrowing rate is 2 copies / person, the monthly average total number of borrowers is 10 people, the average borrowing cycle is 30 days, the safety factor takes 1.5, and the existing number of copies is 3 copies. Then the theoretical supplementary number of copies = 2 copies / person × 10 people × 30 days ÷ 30 days × 1.5 - 3 copies = 27 copies.

[0062] The actual supplementary number of copies needs to consider the procurement cost and the library's collection capacity. Therefore, the theoretical supplementary number of copies can be adjusted to a suitable range as the actual supplementary number of copies. For example, the theoretical supplementary number of copies of 27 copies is adjusted to the range of 5 - 10 copies as the actual supplementary number of copies.

[0063] To ensure the rationality of the actual replenishment copy quantity, the library also needs to balance between the book guarantee rate and the book procurement cost. For example, if the procurement cost per single copy of a book is 100 yuan and 10 copies need to be replenished, it will cost 1000 yuan. If the annual circulation volume of this book is 240 copies (the average monthly borrowing volume is 20 copies), then each copy serves 24 people per year, and the cost-benefit ratio is 24:1, meeting the library's procurement standard (usually requiring that the number of people served per single copy per year is not less than 10).

[0064] To further ensure the accuracy of borrowing data, a dynamic monitoring mechanism can also be introduced. Specifically, this dynamic monitoring mechanism can be: real-time capture of borrowing data through the OPAC (Online Public Access Catalog) system, and set automatic warnings (such as triggering an alarm when the weekly increase in borrowing volume exceeds 50% so that relevant personnel can manually verify the borrowing data after receiving the alarm).

[0065] To facilitate the determination of the replenishment copy quantity of books, a hierarchical response mechanism can also be introduced. This hierarchical response mechanism can be divided into a first-level response and a second-level response. The first-level response means that if the average monthly borrowing volume is 15 - 20 copies and the average monthly reservation number is 5 - 10 people), then 3 - 5 copies need to be replenished (that is, the actual replenishment copy quantity is 3 - 5 copies). The second-level response means that if the average monthly borrowing volume is greater than 20 copies and the average monthly reservation number is greater than 10 people, then 5 - 10 copies need to be replenished (that is, the actual replenishment copy quantity is 5 - 10 copies).

[0066] To evaluate the effect after replenishing the copies, the borrowing data of the books after replenishing the copies can be tracked for 3 months. If the average monthly borrowing rate in 3 months drops by 30% compared to before replenishing the copies and the reservation number is zero, it is regarded as a reasonable replenishment; otherwise, the relevant thresholds (that is, the borrowing rate threshold and the waiting number threshold) need to be reset.

[0067] As a possible implementation method, updating the initial book purchase list based on the procurement copy quantity of the target book in step S108 above can include: if the procurement copy quantity includes the first procurement copy quantity, then adjust the initial procurement copy quantity of the corresponding popular books in the initial book purchase list based on each obtained first procurement copy quantity; if the procurement copy quantity includes the second procurement copy quantity, then adjust the initial procurement copy quantity of the corresponding unpopular books in the initial book purchase list based on each obtained second procurement copy quantity; if the procurement copy quantity includes the third procurement copy quantity, then generate corresponding book purchase information for the corresponding emerging demand books based on each obtained third procurement copy quantity, and add the obtained book purchase information to the initial book purchase list.

[0068] For example, when the initial purchase copy quantity of a popular book is already included in the initial book purchase list, if it is determined that the actual purchase copy quantity of the popular book is 5 - 10 copies, the initial purchase copy quantity of the popular book in the initial book purchase list can be randomly adjusted to a value within 5 - 10 copies (such as 8 copies). For another example, when the initial purchase copy quantity of an unpopular book is already included in the initial book purchase list, if it is determined that the actual purchase copy quantity of the unpopular book is 0 copies, the initial purchase copy quantity of the unpopular book in the initial book purchase list can be adjusted to 0 copies or the relevant information of the unpopular book in the initial book purchase list can be deleted. For still another example, when the initial purchase copy quantity of a book with emerging demand is not included in the initial book purchase list, if it is determined that the actual purchase copy quantity of the book with emerging demand is 10 copies, a new purchase information of the book with emerging demand can be added to the initial book purchase list according to the relevant information of the book with emerging demand (including the actual purchase copy quantity, book title, unit price, author, ISBN number, etc.) to represent the purchase demand of the book with emerging demand.

[0069] As a possible implementation manner, before the above step S104 (i.e., classifying and storing the borrowing data of the target library corresponding to different data sources into the target database to associatively store the borrowing data of the same book through the target database), the above book purchase regulation method based on borrowing data further includes: cleaning the borrowing data.

[0070] Among them, cleaning may include removing error data, removing duplicate data, removing incomplete data, etc. For example, correcting the borrowing date error caused by system failure, deleting test data, etc.

[0071] As a possible implementation manner, the above book purchase regulation method based on borrowing data may further include: classifying and storing the actual borrowing data of the newly purchased books in the target library corresponding to different data sources into the target database, and adjusting the updated book purchase list based on the actual borrowing data in the target database, its bound classification information, and preset expected data; where the preset expected data includes the basic expected borrowing rate of the newly purchased books and its adjustment coefficient.

[0072] For example, after a new book is purchased and put on the shelves of a library, the actual borrowing situation of the new book is continuously tracked (such as classifying and storing the actual borrowing data of the new book in the target database and calculating the average monthly borrowing volume of the new book and other information), and the actual borrowing situation of the new book is compared with the expected borrowing situation of the new book (such as the expected average monthly borrowing volume and other information). If it is found that the actual borrowing situation does not match the expected borrowing situation, the subsequent purchase strategy of the new book is adjusted in time (that is, the purchase information of the new book in the updated book purchase list is adjusted). In addition, the relevant staff of the library can also analyze the reasons why the actual borrowing situation does not match the expected borrowing situation (such as insufficient publicity, the content of the book does not meet the expectations of readers, etc.), and then adjust the subsequent purchase decision of the new book according to the analyzed reasons (such as reducing the number of purchased copies of similar books in the updated book purchase list or changing the type distribution of purchased books in the updated book purchase list, etc.).

[0073] In order to accurately reflect the expected borrowing situation of books, the following expected borrowing volume model can be established:

[0074] Basic expected borrowing volume = number of students in the corresponding grade × book correlation coefficient × grade adaptation coefficient;

[0075] Expected borrowing volume = basic expected borrowing volume × adjustment coefficient;

[0076] Among them, the values ​​of the subject correlation coefficient and the grade adaptation coefficient are both between 0 and 1. For example, the subject correlation coefficient of Chinese books is 0.6, the subject correlation coefficient of science books is 0.3, the grade adaptation coefficient of lower grades (such as elementary school) is 0.4, and the grade adaptation coefficient of higher grades (such as junior high school and high school) is 0.7.

[0077] In actual application, the basic expected borrowing volume of books can be adjusted according to the time range of reading activities such as World Book Day, campus reading festival, and class reading club. The adjustment coefficient is 1 during non-reading activities, and the adjustment coefficient is 1.5-2 during reading activities (that is, the expected borrowing volume during reading activities will increase by 50%-100%). For example, if the shelf time of a book coincides with "World Book Day", the expected borrowing volume of the book = basic expected borrowing volume × 1.5.

[0078] For ease of understanding, the implementation of the above-mentioned book purchasing and control method based on borrowing data is described as follows by taking a specific application as an example.

[0079] The above-mentioned book purchase control method based on borrowing data is mainly implemented by the following steps:

[0080] Step 1: Generate an initial book purchase list.

[0081] Relevant personnel can generate an initial book purchase list for the library based on the Regulations for Primary and Secondary School Libraries and the collection data recorded in the library system (including the existing number of copies of the books in the collection, etc.). This initial book purchase list includes book purchase information (including book title, unit price, initial purchase quantity of copies, etc.) to provide basic data for subsequent optimization of book purchase decisions.

[0082] Step 2: Collection and collation of borrowing data.

[0083] To ensure that the library's borrowing system can accurately record the borrowing information of each book (including book title, author, ISBN number, borrowing time, return time, etc.), the borrowing data of the same book from different branches and different borrowing channels can be collected and integrated into a unified database for associated storage, so as to conduct a comprehensive analysis of the borrowing data subsequently; then, the borrowing data in the database can be cleaned to remove incorrect records, duplicate records, and incomplete records; after that, the cleaned borrowing data in the database can be classified according to classification criteria such as book category (such as literature, science and technology, history, social science, etc.), reader group (such as primary school, junior high school, senior high school, etc.), borrowing frequency (such as high borrowing frequency, medium borrowing frequency, low borrowing frequency, etc.), book series (such as literary novels, science fiction novels, etc.), new or old (such as new books, old books, etc.) so that relevant personnel can more clearly understand the borrowing situation of different types of books after a comprehensive analysis of the borrowing data subsequently.

[0084] Step 3: Analysis of borrowing data.

[0085] Analysis of popular books: Popular books can be identified by statistically analyzing the borrowing indicators of each book (including borrowing frequency, renewal rate, reservation volume, timely return rate, reader rating, etc.). Specifically, the borrowing indicator data (i.e., borrowing frequency, renewal rate, reservation volume, timely return rate, reader rating) of each book can be calculated for one month and one quarter respectively. The weight of the monthly borrowing indicator data is 40%, and the weight of the quarterly borrowing indicator data is 60%. And in the weight distribution, the weight of borrowing frequency (35%) > the weight of reservation volume (25%) > the weight of renewal rate (20%) > the weight of timely return rate (10%) > the weight of reader rating (10%). Then, the comprehensive borrowing score of each book can be calculated using the monthly borrowing indicator data, quarterly borrowing indicator data, and the corresponding weights, and the comprehensive borrowing scores of similar books can be compared in combination with the type of each book. Furthermore, books with a borrowing number exceeding a certain value (such as 100 times) or a borrowing number significantly greater than that of other books of the same type can be regarded as popular books.

[0086] Borrowing trend analysis: By analyzing the changing trend of book borrowing data over time, it is possible to determine whether the popularity of a book is increasing, decreasing, or remaining stable. Specifically, tools such as line charts can be used to visually display the borrowing trend of books. For example, the borrowing volume of a certain series of popular science books has shown a gradually increasing trend in the past few quarters, which may indicate an increasing demand for the knowledge covered in this series of popular science books among readers.

[0087] Reader demand analysis: By using the borrowing data stored in categories in the database, combined with the attribute information of readers such as age, gender, grade, and the borrowing behavior data of readers (such as the data generated after readers browse the book web pages and perform actions such as liking, collecting, and purchasing), as well as preference data such as questionnaire survey data, the borrowing preferences of different reader groups can be analyzed.

[0088] Step 4: Formulate procurement control strategies.

[0089] Supplementary purchase of popular books: For books with high borrowing frequencies and continuous popularity, increase the number of copies to update the initial procurement list. For example, if a popular English tutoring book is frequently borrowed, and the existing number of copies in the library cannot meet the needs of readers, resulting in many readers having to wait to borrow, more copies should be considered for purchase. Specifically, the number of supplementary copies can be determined based on the borrowing rate, the number of people waiting to borrow, and the existing number of copies in the library. For example, if the borrowing rate results in an average monthly borrowing frequency exceeding a certain threshold (such as more than 20 times per month) and the number of people waiting to borrow is relatively large (such as more than 10 people), 5 - 10 additional copies can be added, and the initial procurement list can be updated according to the number of additional copies. The method for determining the number of supplementary copies can refer to the relevant content above and will not be elaborated here.

[0090] Response to emerging demands: When it is found that the borrowing trend of a certain type of book is on the rise, relevant new books, classic works, etc. are regarded as emerging demand books, and the procurement information of emerging demand books is added to the initial procurement list. Generally, emerging demand books are purchased in a timely manner subsequently.

[0091] Optimization of unpopular books: For unpopular books that have not been borrowed for a long time, reduce their procurement volume or remove them to update the initial procurement list. Specifically, a standard can be set to determine unpopular books (such as books that have not been borrowed for more than one year are determined as unpopular books). The procurement quantity of unpopular books in the initial procurement list can be reduced to update the initial procurement list, or the procurement information of unpopular books can be deleted from the initial procurement list to update the initial procurement list, or unpopular books can be moved to the warehouse for storage to make room for more popular books. For some professional books with academic value but low borrowing rates, a certain number of copies can be appropriately retained to meet the needs of specific readers.

[0092] Step 5: Implement procurement and feedback adjustment.

[0093] Procurement implementation: Communicate with book suppliers according to the formulated procurement control strategy, and implement book procurement based on the updated book procurement list. During the procurement process, pay attention to factors such as the quality, version, and price of books. For example, ensure that the purchased books are the latest version, avoid buying pirated books, and strive for reasonable prices and favorable conditions.

[0094] Feedback and adjustment: After the newly purchased books are shelved, continuously track their actual borrowing situations, and compare them with the previous borrowing data and the expected borrowing situations. If it is found that the actual borrowing situation does not match the expected borrowing situation, promptly adjust the procurement information of the new book in the updated book procurement list.

[0095] The beneficial effects of the above book procurement control method based on borrowing data are mainly reflected in the following aspects:

[0096] (1) Precise procurement decision-making: By deeply analyzing borrowing data, it is possible to accurately determine the demand levels of different categories of books, optimize the allocation of book procurement resources as a whole, and ensure that funds are used to purchase appropriate books; and borrowing data can reflect the reading preferences of different reader groups (such as readers of different ages, genders, and grades). When purchasing books, different types of books can be purchased targeted according to the composition and demand characteristics of the reader group, better meeting the diverse reading needs and improving readers' satisfaction with the library's collection.

[0097] (2) Improving the efficiency of fund use: The previous book procurement methods may be blind due to the lack of sufficient data support. Adopting the above book procurement control method based on borrowing data can help the library clearly understand which books are truly needed by readers and which books may be neglected, thus avoiding purchasing unpopular books, reducing waste of funds, and increasing the proportion of funds used to purchase popular books and high-demand books; and borrowing data can help determine the reasonable number of copies of books. By analyzing borrowing data, the number of copies to be purchased can be accurately calculated, which can not only meet readers' borrowing needs, reduce readers' waiting time, but also avoid over-purchasing resulting in library inventory backlogs, thereby improving the efficiency of fund use in copy procurement.

[0098] (3) Enhancing the adaptability and timeliness of the collection: By continuously tracking borrowing data, changes in reading trends can be detected in a timely manner, facilitating the library to adjust procurement decisions promptly according to changes in reading trends, enabling the collection to quickly adapt to changes in reading trends and maintaining a close combination between the collection of books and readers' interests; for some fields with rapid knowledge updates, borrowing data can help the library update the knowledge content of the collection of books, ensuring that the collection of books can provide readers with the latest and most accurate knowledge and improving the knowledge timeliness of the collection of books.

[0099] (4) Improve the quality of reader services: When the library purchases books reasonably according to the borrowing data, the inventory of popular books can be effectively guaranteed, and the waiting time for readers to borrow these books will be greatly shortened, improving the satisfaction of the reader borrowing experience.
