Description

  The present technology relates to a technology for providing information related to books.

  Usually, bookshelves in a library are arranged by field and by writer, but popular books are always lent out and rarely exist on bookshelves. Even if you make a reservation without having the book in hand just because it is popular, it may be different from the book you thought after borrowing. Specifically, the size is larger than expected, the number of pages is larger than expected. For this reason, it may occur that reading becomes abundant and abandoned on the way, or that it is difficult to return. Also, there is a problem that another person waiting for the reservation cannot be borrowed until the person returns.

  For this reason, you may see the book in advance in the bookstore instead of the library, but if you go to the bookstore and see the actual thing, but wait for the reservation of the library, you will buy it at the bookstore There is also a case. This contributes to leaving the library.

  An overview of a system according to an embodiment of the present technology is shown in FIG. For example, one or a plurality of library terminals 5 and a library server 3 that executes main processing in the present embodiment are connected to a network 1 that is the Internet or a LAN (Local Area Network) in a library. When the network 1 is connected to a network outside the library such as the Internet or when the library LAN is released, the user terminal 7 may be connected.

  The library terminal 5 is installed in a library, for example, and includes, for example, a touch panel display unit, a barcode reader 8 and the like. May have a hardware keyboard. The library terminal 5 is assumed to be running a Web browser. It is assumed that the user terminal 7 is also executing a Web browser.

  FIG. 2 shows a functional block diagram of the library server 3. The library server 3 includes a request processing unit 31, a data extraction unit 32, a user DB 33, a lending DB 34, a book DB 35, a reservation DB 36, a lending history DB 37, and a terminal position DB 38. The request processing unit 31 receives a request from the library terminal 5 or the like, requests the data extraction unit 32 for data corresponding to the request, and returns display data to the requesting library terminal 5 or the like. The data extraction unit 32 extracts data from the lending DB 34 and the book DB 35 in response to a request from the request processing unit 31.

  In the present embodiment, the user DB 33 is used for user authentication, for example, and at least a user ID and a password are registered.

  The book DB 35 stores data as shown in FIG. 3, for example. In the example of FIG. 3, the book ID (for example, ISBN (International Standard Book Number) or a unique book ID assigned by the library), title, author name, sample screen storage address, size, number of pages, The thickness of the spine and the number of the shelf on which the book is placed are registered. In the size field of the book DB 35, names corresponding to size names such as A6 size, A7 size, and 46 size may be stored. The book DB 35 also stores actual size data. In addition, it is assumed that the library DB 35 also stores shelf layout data in the library. The shelf layout diagram includes the layout position of each library terminal 5.

  Further, for example, data as shown in FIG. 4A is stored in the lending DB 34. In the example of FIG. 4A, the real ID, the real title, the user ID of the borrower, the loan date, and the scheduled return date are stored. A book with a book ID that is not registered in the loan DB 34 is “available for loan”. FIG. 4B shows an example of data stored in the loan history DB 37. Past loan data is registered in the loan history DB. That is, a past rental destination user ID, a past rental date, and a past return date are registered in association with the main ID and the main title. When the book that is being loaned is returned, the record corresponding to the book is deleted from the loan DB 34, and the loan history and the return date are associated with the book ID and title of the record in the loan history DB 37. The date is registered. Further, at the time of lending, a record corresponding to the lent book is newly registered in the lending DB 34, and a lending destination user ID, a lending date, and a scheduled return date are registered.

  As shown in FIG. 4C, the reservation DB 36 registers, for example, a book ID of a book to be reserved, a book title, a user ID of a reservation person, a reservation ID, and a reservation date. The reservation number may also indicate the reservation priority for the book.

  The terminal position DB 38 stores data as shown in FIG. 4D, for example. In the example of FIG. 4D, the terminal ID of the library terminal 5 and the adjacent shelf number are stored in association with each other.

  Next, processing contents of the system shown in FIG. 1 will be described with reference to FIGS. It is assumed that the user grasps the user ID on the library server 3 side after operating the library terminal 5 and the like and performing user authentication with respect to the library server 3. The search condition input page is already displayed on the display unit of the library terminal 5 or the like. Here, it is assumed that the user searches for a book.

  The library terminal 5 or the like accepts input of search conditions from the user, and transmits a search request including the search conditions to the library server 3 (FIG. 5: Step S1). The request processing unit 31 of the library server 3 receives a search request including a search condition from the library terminal 5 or the like (step S3), and outputs the search condition to the data extraction unit 32. Then, the data extraction unit 32 searches the book DB 35 with the search condition to extract data that matches the search condition, searches the lending DB 34 with the book ID included in the data that matches the search condition, and Data associated with the real ID is extracted (step S5). As a result, it is possible to obtain book data that matches the search condition and data indicating whether or not the book is being lent. The data extraction unit 32 outputs such a search result to the request processing unit 31.

  The request processing unit 31 generates page data including such a search result and transmits it to the requesting library terminal 5 or the like (step S7). The Web page includes, for example, a list including a book title, a writer, a sample image, a status, and a check box, a reservation button for reserving any book, and a lending detail display page unique to the present embodiment. And a button for displaying.

  Then, the library terminal 5 or the like receives page data including the search result from the library server 3 and displays it on the display unit (step S9). For example, a search result display page as shown in FIG. 6A is displayed. The search result display page includes a comparison request button in addition to the reservation button for books that are being lent. There are no buttons on books that can be borrowed. There is also a button for displaying a list of materials on loan. Here, when the user clicks the reservation button (step S11: Yes route), the processing shifts to the processing of FIG.

  On the other hand, when the rented material list display button is clicked instead of the reservation button (step S12: Yes route), the library terminal 5 or the like transmits a request for the lent material list display page to the library server 3 (step S12). S13). When the request processing unit 31 of the library server 3 receives the request for the list of materials being rented from the library terminal 5 or the like (step S15), the request processing unit 31 narrows down to the books that are lent out of the books extracted in step S5, Lending list display page data for the book is generated and transmitted to the requesting library terminal 5 or the like (step S17). The on-lending list display page includes a list including a title, a writer, a cover image, and a check box, and a comparison request button. On the other hand, when any of the book comparison request buttons is clicked on the search result display page (step S12: No route), the process proceeds to step S21.

  On the other hand, the library terminal 5 or the like receives the rented material list display page data from the library server 3 and displays it on the display unit (step S19). An example of the lent material list display page is shown in FIG. 6B. The example of FIG. 6B shows a loan detail display page for the search condition “writer = Taro Yamada”, and three books are being loaned. The user clicks a comparison request button after checking a check box for one book.

  The library terminal 5 or the like receives a book selection input and a comparison request instruction from the user, and transmits a selected book comparison request to the library server 3 (step S21). For example, it is assumed that “Kobe Ferry Incident” is selected. The request processing unit 31 of the library server 3 receives the selected book comparison request from the library terminal 5 or the like (step S23). The processing shifts to the processing in FIG. 7 via terminals B and C.

  Shifting to the processing of FIG. 7, the request processing unit 31 generates comparison menu page data for the selected book and transmits it to the library terminal 5 or the like (step S25). At this time, the comparison menu page data can be made different depending on whether or not the user ID is registered in the lending DB 34. For example, when the ID of the user is registered in the loan DB 34 (when the user borrows a book), “Compare with borrowed book” is displayed as the menu of the comparison menu page data, and the loan DB 34 is displayed. When the user's ID is not registered (when the user has not borrowed a book at present), “comparison with recently borrowed book” can be displayed as the menu of the comparison menu page data. This recently borrowed book can be extracted by searching for a book borrowed during a predetermined period (for example, two months) using the loan history DB 37. Furthermore, if the user ID is not registered in the loan DB 34 and there is no history of borrowing a book within the predetermined period of the loan history DB 37, this menu item ("Compare with borrowed book"). Or “Compare with recently borrowed books”) can be hidden. The library terminal 5 or the like receives the comparison menu page data for the selected book from the library server 3 and displays it on the display unit (step S27). For example, a display as shown in FIG. 8 is performed. In the example of FIG. 8, as comparison methods with the selected book “Kobe Ferry Incident”, there are 3 methods of “Compare with borrowed books”, “Compare with arbitrary books”, and “Teach books of similar size”. Two methods are shown, each with a button.

  The library terminal 5 or the like accepts a selection input by a user clicking a button, and transmits selection data representing the selected menu to the library server 3 (step S29). The request processing unit 31 of the library server 3 receives selection data representing the selected menu from the library terminal 5 or the like (step S31). Then, the request processing unit 31 determines whether comparison with the borrowed book is requested based on the selection data (step S33). When the comparison with the borrowed book is not requested, the processing shifts to the processing of FIG.

  On the other hand, when the comparison with the borrowed book is requested, the request processing unit 31 outputs the logged-in user ID to the data extraction unit 32. Then, the data extraction unit 32 searches the loan DB 34 with the user ID, and specifies the book ID of the book borrowed by the user, that is, the book whose loan destination user ID matches the user ID of the search condition (step S31). S35). As a general rule, the book ID of the book currently borrowed is specified.

  Then, the data extraction unit 32 searches the book DB 35 with the book ID of the book borrowed by the user, that is, the book ID specified in step S35, and reads the detailed data of the book borrowed by the user (step S37). . The data extraction unit 32 outputs the extracted detailed data of the book to the request processing unit 31.

  The request processing unit 31 generates comparison page data between the selected book and the book borrowed by the user, and transmits it to the library terminal 5 or the like (step S39). Then, the library terminal 5 or the like receives comparison page data between the selected book and the book borrowed by the user, and displays it on the display unit (step S41). For example, a comparison page as shown in FIG. 9 is displayed.

  The example in FIG. 9 shows an example of borrowing the books “Tokyo Murder Case” and “Hirota no Hito”, comparing the size with the “Kobe Ferry Case” and the number of pages for each. And comparison of the spine cover thickness and comparison results.

  The size comparison represents a comparison of the sizes included in the detailed data. In the example of FIG. 9, the selected book “Kobe Ferry Incident” is represented by a solid rectangle having a vertical and horizontal standard length. The target book is represented by a dotted rectangle with a length and width determined by the product of the ratio of the length and width of the comparison target to the length and width of the selected book and the length of the standard length and width. It is represented by a figure that is overlapped so that the vertices overlap. That is, the two are reduced at a predetermined reduction rate and overlapped into different destination rectangles.

  The comparison of the number of pages includes comparison data based on the number of pages included in the detailed data. Specifically, the number of pages borrowed by the user and the number of pages of the book borrowed by the user are selected. And the percentage of the number of pages in the book.

  Further, the thickness of the spine cover represents a comparison of the spine cover thickness included in the detailed data, and a solid line rectangle having a vertical length corresponding to the thickness of the book borrowed by the user and the selected book Dotted rectangles (rectangles reduced to the same scale) corresponding to the thickness of each are arranged in the vertical direction.

  The comparison result includes a size determination result for the size of the book borrowed by the user, a size determination result for the number of pages, and a size determination result for the thickness.

  In addition, a button for reserving the selected book after viewing this result is also provided.

  The request processing unit 31 executes processing for performing such display. That is, a figure for size comparison is generated, the ratio of the number of pages is calculated, a figure for back cover thickness comparison is generated, and the size, page number, and thickness are determined.

  By making such a display, a book that has been borrowed by other users and does not exist on the bookshelf in the library can be compared with a book that the person currently borrows (or a book that has been borrowed recently). By showing it before and giving it a feeling, you can avoid giving it the impression that it is different from the book you were thinking after borrowing.

  Here, when the user clicks the reservation button (that is, when “Kobe Ferry Murder Case” is reserved) (step S43: Yes route), the process proceeds to the process of FIG. On the other hand, if the reservation button is not clicked (step S43: No route), it is determined whether or not the user has clicked the end button on the comparison page, and if clicked (step S44: Yes route), the process proceeds to FIG. The process ends. If not clicked, the process returns to step S43. In short, it waits until the reservation button is pressed or the end button is pressed.

  Next, processing after the terminal D will be described with reference to FIG. If the request from the library terminal 5 or the like is not a comparison request with the book that has been borrowed, the request processing unit 31 determines whether or not the comparison is with any book based on the received selection data. (Step S45). If the request is not a comparison with an arbitrary book, the processing shifts to the processing in FIG.

  On the other hand, when the request is a comparison with an arbitrary book, the request processing unit 31 transmits the barcode input request page data to the library terminal 5 or the like (step S47). The library terminal 5 or the like receives the barcode input request page data from the library server 3 and displays it on the display unit (step S49). The barcode input request page is provided as hardware on the keyboard displayed on the touch panel, the library terminal 5, etc., for example, the barcode value attached to the book held by the user (ie, the book ID). This is a page for inputting to the library server 3 by reading the barcode attached to the book with the barcode reader provided in the library terminal 5 or the like. For example, a message as shown in FIG. 11A is displayed.

  The library terminal 5 or the like receives the input of the barcode data (that is, the book ID) and transmits the barcode data to the library server 3 (step S51). Then, the request processing unit 31 of the library server 3 receives the barcode data from the library terminal 5 or the like (step S53). Then, the request processing unit 31 outputs the book ID, which is barcode data, to the data extraction unit 32, and extracts detailed data about the book ID. That is, the data extraction unit 32 searches the book DB 35 with the received book ID, extracts detailed data associated with the book ID (step S55), and outputs it to the request processing unit 31. The request processing unit 31 generates comparison page data between the selected book and the book specified by the barcode data, and transmits it to the library terminal 5 or the like (step S57). The library terminal 5 or the like receives comparison page data between the selected book and the book specified by the barcode, and displays it on the display unit (step S59).

  The comparison page displayed here is basically the same as the comparison page shown in FIG. 9 except that the comparison target is not a book borrowed by the user but an arbitrary designated book. It is. For example, a comparison page as shown in FIG. 11 is displayed. Here, a case where the designated book is “a man of Awaji Island” is shown. The method of comparison is the same as in FIG.

  By displaying such a book, borrowed by other users, books that do not exist on the bookshelf in the library, compared with the book specified by the user before booking, gave a sense of reality You can avoid giving the impression that it is different from the book that you thought later.

  Here, when the user clicks the reservation button (step S61: Yes route), the processing shifts to the processing in FIG. On the other hand, if the reservation button is not clicked (step S61: No route), it is determined whether or not the user has clicked the end button on the comparison page, and when the user clicks (step S62: Yes route), FIG. The process ends. If not clicked, the process returns to step S61. In short, it waits until the reservation button is pressed or the end button is pressed.

  Next, processing after the terminal F will be described with reference to FIG. If the request from the library terminal 5 is not a comparison with an arbitrary book, it is a request to teach a book of the same size. Therefore, the request processing unit 31 extracts size data from the detailed data of the selected book, and outputs the data to the data extraction unit 32 to request extraction of a book of similar size. At this time, the spine cover thickness and the number of pages may also be extracted and output to the data extraction unit 32.

  Then, the data extraction unit 32 searches the book DB 35 with the received size (including the back cover thickness and the number of pages in some cases), and details of the book having a size similar to the size of the selected book. Data is extracted (step S63). For similar sizes, a similar range is defined for each size in advance, and a book that matches a size that falls within the similar range of the selected book sizes is extracted. In addition, when considering the thickness of the spine and the number of pages, detailed data of a book having a numerical value within plus or minus a predetermined percentage from the spine thickness or the number of pages of the selected book, such as within plus or minus 10%. Extract. The data extraction unit 32 outputs such an extraction result to the request processing unit 31. Note that the loan DB 34 may be further searched and limited to books whose status is “loanable”.

  Further, the request processing unit 31 extracts detailed data of a book close to the position of the communication partner (here, the library terminal 5 or the like) from the extracted books (step S65). In the shelf layout diagram in the library stored in the book DB 35 or the like, the books arranged on the shelves within a predetermined range are narrowed down with the requesting library terminal 5 or the like as the center. You may limit to the book arrange | positioned on the nearest shelf. Specifically, it is possible by searching the book DB 35 for a book placed in the adjacent shelf number corresponding to the requesting terminal ID from the terminal position DB 38.

  Then, the request processing unit 31 generates page data including a shelf number of a book similar in size from the extracted detailed data of the book, and transmits it to the library terminal 5 or the like (step S67). The library terminal 5 or the like receives page data including a shelf number of a book similar in size from the library server 3, and displays it on the display unit (step S69). For example, a page as shown in FIG. 13 is displayed. In the example of FIG. 13, a title and author name of a similar size, a cover image, a shelf number, and a reservation button are provided. In order to make the shelf number easy to understand, a shelf layout drawing may be included. Further, in the shelf layout diagram, the current position (position of the library terminal 5 or the like) and the position of the shelf with the displayed shelf number may be highlighted.

  By displaying in this way, books that are borrowed by other users and do not exist on the bookshelf in the library can be replaced with similar-sized books and the size etc. can be realized before booking, after borrowing You can avoid giving the impression that it is different from the book you were thinking of.

  If the reservation button is not clicked (step S71: No route), it is determined whether or not the end button is clicked (step S82). If the end button is clicked, the main menu is returned to. The process is terminated. If the end button has not been clicked, the process returns to step S71. In short, it waits until the reservation button or the end button is clicked. On the other hand, when the user clicks the reservation button (step S71: Yes route), the library terminal 5 or the like transmits a reservation request for the selected book to the library server 3 (step S73). When the request processing unit 31 of the library server 3 receives a reservation request for the selected book from the library terminal 5 or the like (step S75), the reservation data of the selected book is registered in the reservation DB 36 (step S77). ). For example, a record including a user ID, a real ID, a reservation number, and a reservation date / time is registered. The reservation number is preferably assigned so as to indicate the priority order for the same book.

  Then, the request processing unit 31 generates reservation completion page data including the reservation number and transmits it to the library terminal 5 or the like (step S79). The library terminal 5 or the like receives the reservation completion page data including the reservation number and displays it on the display unit (step S81).

  This allows the user to obtain a reservation number.

  Although the embodiment of the present technology has been described above, the present technology is not limited to this. For example, the processing flow described above is an example, and as long as the processing result does not change, the processing order may be changed or a plurality of steps may be executed in parallel. Furthermore, the functional block configuration may not match the program module configuration. The same applies to the database configuration. Further, the library server 3 may be configured by a plurality of computers instead of the computer. The screen configuration is merely an example, and other screen configurations and expression methods for presenting substantially the same information may be adopted. Furthermore, as a comparison target, in the above-described embodiment, the size, the number of pages, and the back display are used. However, when the number of characters is registered in the book DB 35, the comparison of the number of characters may be included. Further, a non-contact tag or the like may be used as the barcode in the embodiment described above. Further, the library server 3 generates a web page and the library terminal 5 displays the page using a web browser. However, the library server 3 is not limited to the web page or the browser, and is determined in advance between the server and the terminal depending on the situation. It is also possible to exchange screen data.

  In addition, as described above, the user terminal 7 may be used instead of the library terminal 5, but when processing is performed based on the installation location, for example, a shelf layout diagram for designating the current position is given first. Processing may be performed after distribution and having the user specify the position in the shelf layout drawing.

  The library server 3, library terminal 5, and user terminal 7 described above are computer devices, and as shown in FIG. 14, a memory 2501, a CPU (Central Processing Unit) 2503, a hard disk drive (HDD: Hard). Disk Drive) 2505, a display control unit 2507 connected to the display device 2509, a drive device 2513 for the removable disk 2511, an input device 2515, and a communication control unit 2517 for connecting to a network are connected by a bus 2519. . An operating system (OS) and an application program for executing the processing in this embodiment are stored in the HDD 2505, and are read from the HDD 2505 to the memory 2501 when executed by the CPU 2503. The CPU 2503 controls the display control unit 2507, the communication control unit 2517, and the drive device 2513 according to the processing content of the application program, and performs a predetermined operation. Further, data in the middle of processing is mainly stored in the memory 2501, but may be stored in the HDD 2505. In an embodiment of the present technology, an application program for performing the above-described processing is stored in a computer-readable removable disk 2511 and distributed, and installed from the drive device 2513 to the HDD 2505. In some cases, the HDD 2505 may be installed via a network such as the Internet and the communication control unit 2517. Such a computer apparatus realizes various functions as described above by organically cooperating hardware such as the CPU 2503 and the memory 2501 described above and programs such as the OS and application programs. .

  The above-described embodiment can be summarized as follows.

  In the information processing method according to the present embodiment, (A) the first book identifier selected by the user is specified, and (B) the book identifier and the borrower user identifier are stored in association with each other. The second book identifier associated with the user identifier is extracted from the data storage unit, and (C) at least one of the book size and quantity and the book identifier are stored in association with each other. Extract at least one of the size and quantity associated with the second book identifier from the second data storage unit, and (D) use the second data storage unit as the first book identifier. It includes processing for generating and outputting data representing the difference between at least one of the associated size and quantity and at least one of the second book size and quantity.

  In this way, it is possible to easily grasp the actual book to be borrowed.

  The information processing method according to this embodiment specifies (E) the third book identifier selected or input by the user, and (F) corresponds to the third book identifier from the second data storage unit. Extract at least one of the attached size and quantity, and (G) the difference between at least one of the first book size and quantity and at least one of the third book size and quantity It is also possible to further include a process of generating and outputting data representing. Even in this way, it is possible to easily grasp the actual book to be borrowed.

  Furthermore, the second data storage unit described above may further store an identifier of the book arrangement location in association with the book identifier. In the information processing method according to the present embodiment, (H) from the second data storage unit, at least one of the size and the amount similar to at least one of the size and the amount of the first book is obtained. (I) identifying an identifier of another book whose placement location is in the vicinity of the user's location among the extracted identifiers of other books, and (J) A process of outputting an identifier of another identified book and an identifier of an arrangement location may be further included. In this way, when the user goes to the arrangement location, he / she can take a real book having the same size as that of the book to be borrowed and determine whether or not to make a reservation.

  The data representing the difference described above is a diagram comparing the size of the first book and the size of the second book, and a diagram comparing the amount of the first book and the amount of the second book. And at least one of them may be included. The difference can be grasped more specifically.

  It is possible to create a program for causing a computer to carry out the processing described above, such as a flexible disk, an optical disk such as a CD-ROM, a magneto-optical disk, and a semiconductor memory (for example, ROM).
