  Embodiments will be described below with reference to the drawings. FIG. 1 is a diagram showing an example of a disposal scheduled book sorting system.

  The scheduled disposal system 100 according to the present embodiment includes an information processing device 200 and a terminal device 300. In the scheduled disposal system 100, the information processing device 200 and the terminal device 300 are connected via a network or the like.

  The planned disposal system 100 according to the present embodiment is introduced into a facility that stores a large number of books, such as a library, and is a book to be discarded and a book to be stored by a manager of the facility such as a librarian. Assist in sorting.

  The information processing apparatus 200 according to the present embodiment includes a collection database 210, a planned disposal book database 220, a rare value database 230, a keyword database 240, and a planned disposal book output unit 250.

  In the information processing apparatus 200 of the present embodiment, the collection database 210 stores information on books (hereinafter simply referred to as books) stored in the facility. The to-be-discarded book database 220 stores information related to books selected as to be discarded. In the book database 220 to be discarded, information on a book selected by a manager of a facility such as a librarian is stored.

  The scarce value database 230 stores information on the distribution status of books. More specifically, the scarcity value database 230 stores information related to books whose distribution volume is less than a certain amount and generally considered difficult to obtain. The rare value database 230 is created with reference to information or the like held by, for example, a seller who sells books.

  The keyword database 240 stores information indicating specific keywords. The specific keyword is, for example, a name of an event or the like to be held in the future, a word related to a matter currently attracting attention, or the like.

  In addition, the information processing apparatus 200 according to the present embodiment uses the planned disposal book output unit 250 to collate the planned disposal book database 220 with the rare value database 230, and arranges the books scheduled to be discarded in order from the book with the highest rare value. Output a sorted list.

  The list output from the information processing device 200 may be displayed on the terminal device 300. In the present embodiment, for example, when a list output instruction is given in the terminal device 300, the terminal device 300 transmits a list output request to the information processing device 200, and the information processing device 200 displays the list on the terminal device 300. You may let them.

  In the present embodiment, a book with a high scarcity value means a book that is difficult to purchase. In other words, the scarce value in the present embodiment means the degree of difficulty in obtaining. For example, a book that has a large distribution volume and can be easily purchased at a general bookstore or store is a book with low rarity value. On the other hand, it can be said that a book with a small amount of distribution in the market and a limited number of stores selling has higher scarcity value than a book with a large amount of distribution.

  As described above, in the present embodiment, by referring to the scarcity value database 230, the books that are scheduled to be discarded are displayed on the terminal device 300 in descending order of scarcity value, thereby assisting the selection of books to be discarded. More specifically, in the present embodiment, the books that are scheduled to be discarded are displayed in the order in which they are considered difficult to obtain, so that the books that are difficult to obtain and that should be properly stored are discarded by mistake. Can be suppressed.

  Note that the information processing apparatus 200 and the terminal apparatus 300 according to the present embodiment may be provided in a facility such as a library that stores collections, for example. In this case, the collection database 210 and the disposal scheduled book database 220 relate to books stored in this facility.

  In the present embodiment, the information processing apparatus 200 may be a server apparatus on a network, and the terminal apparatus 300 may be provided in a facility such as a library. In this case, the collection database 210 and the planned disposal book database 220 are provided for each facility such as a library.

  In FIG. 1, each database is provided in the information processing apparatus 200, but the present invention is not limited to this. Each database shown in FIG. 1 may be provided in an apparatus other than the information processing apparatus 200. For example, the collection database 210 and the planned disposal database 220 may be provided in the terminal device 300 or may be provided in a device other than the terminal device 300.

  Below, the information processing apparatus 200 of this embodiment is demonstrated. FIG. 2 is a diagram illustrating an example of a hardware configuration of the information processing apparatus.

  The information processing apparatus 200 according to the present embodiment includes an input device 21, an output device 22, a drive device 23, an auxiliary storage device 24, a memory device 25, an arithmetic processing device 26, and an interface device 27 that are connected to each other via a bus B.

  The input device 21 is a device for inputting various information, and is realized by, for example, a keyboard or a pointing device. The output device 22 is for outputting various kinds of information, and is realized by, for example, a display. The interface device 27 includes a LAN card or the like and is used for connecting to a network.

  The planned disposal main output program that realizes the planned disposal main output unit 250 is at least a part of various programs that control the information processing apparatus 200. The scheduled output program is provided, for example, by distributing the storage medium 28 or downloading it from the network. The storage medium 28 on which the output program to be discarded is recorded is a storage medium such as a CD-ROM, a flexible disk, a magneto-optical disk, etc. for recording information optically, electrically or magnetically, a ROM, a flash memory, etc. Various types of storage media such as a semiconductor memory that electrically records information can be used.

  Further, the scheduled disposal main output program is installed from the storage medium 28 to the auxiliary storage device 24 via the drive device 23 when the storage medium 28 storing the planned disposal main output program is set in the drive device 23. The scheduled disposal output program downloaded from the network is installed in the auxiliary storage device 24 via the interface device 27.

  The auxiliary storage device 24 stores the installed scheduled disposal book output program, and stores files, data, and the like necessary for various processes performed by the scheduled disposal book output unit 250. The memory device 25 reads and stores the scheduled output program from the auxiliary storage device 24 when the information processing apparatus 200 is activated. Then, the arithmetic processing unit 26 implements various processes as will be described later in accordance with the scheduled disposal output program stored in the memory device 25.

  Next, each database included in the information processing apparatus 200 will be described with reference to FIGS. 3 to 6. Each database included in the information processing apparatus 200 may be provided in the auxiliary storage device 24, the memory device 25, or the like, for example.

  FIG. 3 is a diagram illustrating an example of a collection database. The collection database 210 of this embodiment has a book ID, book ID, book name, ISBN (International Standard Book Number), material introduction, and status as information items.

  In the collection database 210, the item “book ID” is associated with the other items, and information including the value of the item “book ID” and the values of the other items is referred to as collection information.

  The value of the item “book ID” indicates identification information for specifying the type of book. The value of the item “book ID” indicates identification information for specifying each book. The value of the item “book name” indicates the name of the book. The value of the item “ISBN” indicates the ISBN of the book. ISBN is a number for specifying a book (book) in common throughout the world.

  The value of the item “material introduction” indicates information for introducing the book. The value of the item “state” indicates the state of the book.

  The items of information stored in the collection database 210 and the information structure are not limited to the example shown in FIG. The collection database 210 is created for each facility that stores books, and the items and structure of information may be different for each facility.

  FIG. 4 is a diagram illustrating an example of the book database to be discarded. The planned disposal book database 220 of the present embodiment has book ID, book name, ISBN, material introduction, remarks, scarcity value, scarcity value forecast, and demand forecast as information items.

  In the to-be-discarded book database 220, the item “book ID” is associated with other items. In the following description, in the planned disposal book database 220, information including the value of the item “book ID” and the values of other items is referred to as planned disposal information.

  The value of the item “Remarks” indicates whether or not the corresponding book is not for sale. Specifically, as the value of the item “remarks”, when the corresponding book is not for sale, “not for sale” may be input to the value of the item “remarks” by an administrator such as a librarian.

  The value of the item “rare value” indicates the rarity value of the book. The value of the item “rare value prediction” indicates a factor that increases the future rare value of the book. The value of the item “demand forecast” indicates the relationship between a book and an event to be held in the future or a matter that is currently attracting attention.

  The values of the items “remarks”, “rare value”, “rare value forecast”, and “demand forecast” are input by processing of the scheduled disposal output unit 250 described later.

  For example, in the example of FIG. 4, it can be seen that the book with the book ID “11”, the book name “AAA”, and the ISBN “978-4-111111-0” is scheduled to be discarded. Moreover, in the example of FIG. 4, it turns out that this book is not for sale.

  FIG. 5 is a diagram illustrating an example of a rare value database. The rare value database 230 of the present embodiment has ISBN, book name, state, inventory quantity, sales price, and correct price as information items, and the item “ISBN” is associated with other items.

  In the following description, information including the value of the item “ISBN” and the values of other items in the scarcity value database 230 is referred to as scarcity value information.

  The value of the item “state” indicates the state of distribution of the corresponding book. The value of the item “stock quantity” indicates the circulation amount of the corresponding book in the market. The value of the item “sales price” indicates the selling price of the corresponding book. The value of the item “Price” indicates the list price of the corresponding book.

  In the example of FIG. 5, for example, the ISBN is “978-4-99-11111-1”, the distribution state of the book name “BBB” is “out of print”, and the stock quantity is “0”. I understand.

  The rare value database 230 of the present embodiment is created by pre-processing before the processing of outputting a list of books scheduled to be discarded by the planned disposal book output unit 250 is executed.

  FIG. 6 is a diagram illustrating an example of a keyword database. The keyword database 240 of this embodiment stores a plurality of keywords. The keywords stored in the keyword database 240 include, for example, words that appear more than a certain number of times in news, popular words, names of upcoming events, and the like.

  The keyword database 240 of the present embodiment may be created, for example, in the pre-processing when creating the rare value database 230, or may be created by an administrator such as a librarian. Further, the keyword database 240 may be updated periodically.

  Next, functions of the information processing apparatus 200 according to the present embodiment will be described with reference to FIG. FIG. 7 is a diagram illustrating functions of the information processing apparatus.

  The information processing apparatus 200 according to the present embodiment includes a scheduled disposal book output unit 250. The planned disposal main output unit 250 is realized by the arithmetic processing unit 26 of the information processing apparatus 200 reading and executing the planned disposal main output program stored in the auxiliary storage device 24, the memory device 25, or the like.

  The scheduled disposal main output unit 250 of the present embodiment includes an input receiving unit 251, a pre-processing unit 252, a scarcity value determination unit 253, a scarcity value prediction unit 254, a specific field determination unit 255, a price determination unit 256, a demand prediction unit 257, It has a sort unit 258, an output unit 259, and an update unit 260.

  The input receiving unit 251 receives various inputs to the information processing apparatus 200. Specifically, the input receiving unit 251 may receive, for example, an instruction to output a list of books scheduled to be discarded, which is input in the terminal device 300, as a list output request. Further, the input receiving unit 251 of the present embodiment may receive, for example, an input of a book that is scheduled to be discarded. In the following description, a book that is scheduled to be discarded is called a book that is scheduled to be discarded.

  The pre-processing unit 252 performs pre-processing that is performed before processing for outputting a list of books to be discarded. Specifically, the pre-processing unit 252 creates the rare value database 230. Further, the preprocessing unit 252 may create the keyword database 240. Details of processing by the pre-processing unit 252 will be described later.

  The rare value determination unit 253 determines the rare value of the book to be discarded by comparing the book information to be discarded stored in the book database 220 with the rare value information in the rare value database 230. In other words, the scarcity value determination unit 253 functions as a determination unit that determines the degree of difficulty in inputting a book to be discarded from the book information to be discarded and the value information to be discarded.

  The rare value predicting unit 254 collates the planned disposal information with the rare value information, and identifies a factor that is thought to increase the rare value of the future planned book.

  The specific field determination unit 255 determines whether the book to be discarded is a book of a specific field registered in advance. In the specific field determination unit 255, field information indicating a specific field may be set in advance. This field information may be information indicating a specific keyword or information indicating a specific field, for example.

  The price determination unit 256 determines whether the sales price of the book to be discarded is higher than the regular price from the book information to be discarded and the rare value information. That is, the price determination unit 256 determines whether or not the book to be discarded has a higher price than the original publication.

  The demand prediction unit 257 predicts whether future demand for the book to be discarded will increase from the book information to be discarded and the keyword database 240. Specifically, the demand prediction unit 257 determines whether the book is related to the keyword stored in the keyword database 240. In other words, the demand prediction unit 257 determines whether or not the book to be discarded is related to an event to be held in the future or a matter that is currently attracting attention. We expect that future demand will increase.

  The sorting unit 258 sorts the planned disposal information stored in the planned disposal book database 220 in the order in which the scarce value is estimated based on the determination result by each determination unit described above.

  The output unit 259 outputs the scheduled disposal book information rearranged by the sorting unit 258 as a list.

  The update unit 260 updates each database. Specifically, for example, the update unit 260 may periodically update the rare value database 230 and the keyword database 240. Further, for example, when the input receiving unit 251 receives an input of a new book to be discarded, the updating unit 260 stores the book to be discarded corresponding to the book to be discarded in the book to be discarded database 220, and is to be a book to be discarded book database. 220 may be updated.

  Next, the operation of the information processing apparatus 200 according to the present embodiment will be described with reference to FIGS. FIG. 8 is a first flowchart for explaining processing of the information processing apparatus.

  FIG. 8 shows processing for creating the rare value database 230 by the preprocessing unit 252.

  The pre-processing unit 252 of the present embodiment accesses a plurality of sites that sell books on the network, and identifies books whose inventory quantity is equal to or less than a predetermined number (step S801). In other words, the scarce value database 230 stores information obtained from a site that includes a book to be discarded stored in the book to be discarded database 220 as a transaction target.

  Here, the book is specified from the site on the network, but the present invention is not limited to this. In the present embodiment, for example, in an actual bookstore or the like, provision of information regarding a book whose stock quantity is a predetermined number or less may be received.

  Subsequently, the pre-processing unit 252 acquires information indicating the distribution state of the identified book (step S802). Specifically, the pre-processing unit 252 acquires information indicating the state of books at a plurality of accessed sites. The information acquired here is the value of the item “state” in the scarcity value database 230.

  Subsequently, the pre-processing unit 252 acquires information indicating the sales price and the correct price of the identified book (step S803). Specifically, the pre-processing unit 252 acquires the sales price of books from a plurality of sites, for example. At this time, if the sales price is different at each site, the highest or lowest sales price may be acquired, or the average value of the sales prices at each site may be acquired. The information indicating the sales price and the net price acquired here is the value of the item “sales price” and the item “net price” in the scarcity value database 230.

  Subsequently, the pre-processing unit 252 associates the ISBN of the book identified in step S801 with information indicating the state of the book, the selling price, and the net price, and stores them in the scarce value database 230 as scarce value information (step S804), the process is terminated.

  As described above, in the present embodiment, by collecting information related to books whose stock quantity is a predetermined number or less and storing it in the scarce value database 230, it is possible to collect information related to books that have a small distribution volume and are difficult to purchase. A book whose stock quantity is a predetermined value or less is, for example, a book that is out of print or whose supply cannot keep up with demand.

  For example, when creating the keyword database 240, the pre-processing unit 252 of the present embodiment extracts words whose appearance frequency is equal to or higher than a predetermined value from a news site on the network, for example. What is necessary is just to store in 240.

  FIG. 9 is a second flowchart for explaining the operation of the information processing apparatus. FIG. 9 shows a process of outputting a list of planned disposal books by the planned disposal book output unit 250.

  When the input request unit 251 receives an output request for the list of planned books to be discarded, the scarce value determination unit 253 stores the value of the item “remarks” in the planned disposal book database 220. It is determined whether or not there is a book to be discarded that is “not for sale” (step S901).

  In step S901, if there is a corresponding book to be discarded, the scarcity value determination unit 253 registers “not for sale” as the value of the item “rare value” in the book to be discarded book information of the book to be discarded (step S902). ), The process proceeds to step S903 to be described later.

  In step S901, when there is no corresponding book to be discarded, the scarce value determination unit 253 compares (collates) the book to be discarded database 220 with the scarce value database 230 (step S903).

  Subsequently, the rarity value determination unit 253 determines whether or not the book to be discarded that is out of print exists in the book to be discarded (step S904).

  Specifically, the scarcity value determination unit 253 determines whether or not scarcity value information including the same ISBN as the ISBN included in the scheduled disposal information exists in the scarcity value database 230. Then, when the corresponding rare value information exists, the rare value determination unit 253 determines whether the value of the item “state” of the rare value information is “out of print”.

  If there is a corresponding book to be discarded in step S904, the scarcity value determining unit 253 registers “out of print” as the value of the item “rare value” in the book to be discarded information of the book to be discarded (step S905). The process proceeds to step S906 described later.

  In step S904, when there is no corresponding book to be discarded, the scarcity value determination unit 253 determines whether there is a book to be discarded that is not in stock among the books to be discarded (step S906).

  Specifically, the scarcity value determination unit 253 determines whether or not scarcity value information including the same ISBN as the ISBN included in the scheduled disposal information exists in the scarcity value database 230. And the rare value determination part 253 determines whether the value of the item "stock quantity" of this rare value information is "0", when applicable rare value information exists.

  In step S906, if there is a corresponding book to be discarded, the scarcity value determination unit 253 registers “sold out” as the value of the item “rare value” in the book to be discarded book information of the book to be discarded (step S907). The process proceeds to step S908 described later.

  In step S906, if there is no corresponding book to be discarded, the book to be discarded output unit 250 uses the scarcity value predicting unit 254 to find a book to be discarded whose inventory quantity is one remaining among the books to be discarded. It is determined whether or not to perform (step S908).

  Specifically, the scarcity value determination unit 253 determines whether or not scarcity value information including the same ISBN as the ISBN included in the scheduled disposal information exists in the scarcity value database 230. And the rare value determination part 253 determines whether the value of the item "stock quantity" of this rare value information is "1", when applicable rare value information exists.

  In step S908, if there is a corresponding book to be discarded, the book to be discarded output unit 250 uses the scarce value predicting unit 254 to set the value of the item “rare value prediction” in the book to be discarded book information of the book to be discarded to “ "Remaining 1 book" is registered (step S909), and the process proceeds to step S910 described later.

  That is, the scarcity value prediction unit 254 determines that the remaining inventory quantity is small and input becomes difficult in the near future as a factor that increases the scarcity value of the book to be discarded.

  In step S909, when there is no corresponding book to be discarded, the scarcity value predicting unit 254 determines whether there is a book to be discarded that is out of print in the book to be discarded (step S910).

  Specifically, the scarcity value determination unit 253 determines whether or not scarcity value information including the same ISBN as the ISBN included in the scheduled disposal information exists in the scarcity value database 230. Then, when the corresponding rare value information exists, the rare value determination unit 253 determines whether or not the value of the item “state” of the rare value information is “out of print”.

  In step S910, if there is a corresponding book to be discarded, the scarcity value predicting unit 254 registers “scheduled out of print” in the value of the item “rare value forecast” in the book to be discarded book information of the book to be discarded (step S910). S911), the process proceeds to step S912 described later.

  That is, the scarcity value prediction unit 254 is scheduled to be out of print, and input difficulty in the near future is a factor that increases the scarcity value of the book to be discarded.

  In step S910, if there is no book to be discarded, the book to be discarded output unit 250 uses the specific field determination unit 255 to determine whether the book to be discarded in the specific field exists in the book to be discarded. Determination is made (step S912).

  Specifically, the specific field determination unit 255 may determine whether or not a word in a specific field set in advance is included in the item “material introduction” of the book information to be discarded. Further, the specific field determination unit 255 may determine whether there is a book to be discarded in a specific field, for example.

  In step S912, when there is a corresponding book to be discarded, the specific field determination unit 255 registers “specific field” in the value of the item “rare value prediction” in the book to be discarded information of the book to be discarded (step S912). S913), the process proceeds to step S914 described later.

  In other words, the scarcity value prediction unit 254 determines that the book in a specific limited field is a factor that increases the scarcity value of the book to be discarded.

  In step S912, when there is no corresponding book to be discarded, the book to be discarded output unit 250 uses the price determination unit 256 to determine whether there is a book to be discarded whose sales price is higher than the regular price. (Step S914).

  Specifically, the price determination unit 256 determines whether or not the scarce value database 230 includes scarce value information including the same ISBN as the ISBN included in the scheduled disposal information. Then, when the corresponding rare value information exists, the rare value determination unit 253 determines whether or not the value of the item “sales price” of the rare value information is larger than the value of “net price”.

  In step S914, if there is a corresponding book to be discarded, the price determination unit 256 registers “higher price than the list price” as the value of the item “rare value prediction” in the book to be discarded information of the book to be discarded (step S914). S915), the process proceeds to step S916 described later.

  That is, the scarcity value prediction unit 254 determines that the sale price is higher than the original price at the time of publication as a factor that increases the scarcity value of the book to be discarded.

  In step S914, if there is no corresponding planned disposal book, the planned disposal book output unit 250 compares the planned disposal book database 220 with the keyword database 240 (step S916).

  Subsequently, the planned disposal book output unit 250 determines whether or not there is a planned disposal book corresponding to the keyword stored in the keyword database 240 by the demand prediction unit 257 (step S917).

  Specifically, the demand prediction unit 257 compares the value of the item “book name” and the value of the item “material information” of the book information to be discarded with each keyword included in the keyword database 240. Then, the demand prediction unit 257 determines whether or not a keyword in the keyword database 240 exists in the value of the item “book name” and the value of the item “material information”.

  In step S917, when there is a corresponding book to be discarded, the demand prediction unit 257 registers a keyword corresponding to the book to be discarded in the value of the item “demand forecast” in the book to be discarded information of the book to be discarded ( Step S918), the process proceeds to Step S919 described later.

  In other words, in the present embodiment, a book in which a keyword stored in the keyword database 240 is included in a book name or a document introduction is a book related to a matter that may become a topic in the future, and thus the demand may increase. Let there be a book.

  Note that the processing from step S901 to step S917 is performed on all planned disposal book information stored in the planned disposal book database 220.

  In step S917, if there is no corresponding book to be discarded, the book planned output unit 250 sorts the book information to be discarded in descending order of the rare value by the sorting unit 258 (step S919). Details of the processing of the sorting unit 258 will be described later.

  Next, the scheduled disposal book output unit 250 causes the output unit 259 to output a list in which the scheduled disposal books are arranged in the order sorted by the sorting unit 258 to the terminal device 300 (step S920), and ends the process.

  Hereinafter, with reference to FIG. 10, the sorting of the scheduled disposal information by the sorting unit 258 will be described. FIG. 10 is a third flowchart for explaining processing of the information processing apparatus. FIG. 10 shows a process of sorting the scheduled book information by the sorting unit 258.

  The sorting unit 258 of this embodiment groups the scheduled disposal book information in the disposal planned book database 220 according to the priority of the value of the item “rare value” (step S1001).

  It should be noted that the priority of the value of the item “rare value” is held in the sort unit 258 in advance. Here, the priority of the value of the item “rare value” will be described.

  In the present embodiment, the scarce value is considered difficult to purchase. Therefore, a book that is not for sale has the highest scarcity value, and the next book with the highest scarcity value is a book that has a limited number of stocks and is out of print. Following these, books with high scarcity value are books that are not in stock, that is, books that are not in circulation at the present time.

  Therefore, the sorting unit 258 of the present embodiment groups the scheduled disposal information whose item “rare value” is “not for sale” as the group with the highest rarity value. Next, the sorting unit 258 groups the scheduled disposal information whose item “rare value” is “out of print” as a group with the next highest rarity value. Then, the sorting unit 258 groups the scheduled disposal information whose item “rare value” has a value of “insufficient” as a group with the third highest rarity value.

  Subsequently, the sorting unit 258 groups the scheduled disposal book information other than the scheduled disposal book information grouped in step S1001 according to the priority of the value of the item “rare value prediction” (step S1002).

  In the sorting unit 258, the priority of the value of the item “rare value prediction” is set in advance. In the present embodiment, the rare value prediction is to predict a book whose rare value will increase, that is, it will be difficult to obtain (purchase).

  In the present embodiment, the priority of the value of the item “rare value prediction” is given according to the difficulty of acquisition, similarly to the priority of the value of the item “rare value”. Specifically, for example, the book with the value “Rare Value Forecast” of the item “Rare Value Prediction” has less circulation than the book with the value “Rare Value Forecast” of the item “Rare Value Forecast”. It is considered difficult to obtain.

  In this embodiment, the information to be discarded is grouped for each value of the item “rare value prediction” set in this way, and a priority for each value of the item “rare value prediction” is given to each group. .

  Subsequently, in each group, the sorting unit 258 rearranges the scheduled disposal book information with the highest priority in order from the scheduled disposal book information having the largest number of item values (step S1003), and ends the processing.

  Below, with reference to FIG. 11, the process by the disposal planned book output part 250 of this embodiment is demonstrated concretely. FIG. 11 is a second diagram showing an example of the book database to be discarded.

  The scheduled disposal book database 220-1 in FIG. 11 shows a state where the scheduled disposal book database 220 is compared with the rare value database 230 and sorted by the sorting unit 258.

  In the to-be-discarded book database 220-1, the to-be-discarded book information 221 is that the book with the book ID “11” is not for sale, and the keyword “rocket” stored in the keyword database 240 is included in the book name or document introduction. Indicates. The to-be-discarded book information 222 indicates that the book with the book ID “12” is out of print.

  The book information 223 to be discarded shows that the book with the book ID “13” is out of stock (the number of inventory is 0), and the selling price is higher than the regular price. The book information 224 to be discarded indicates that the remaining number of books with the book ID “14” is one and is included in the introduction of the word or book name “Olympic” stored in the keyword database 240. .

  In the example of FIG. 11, the sorting unit 258 includes the scheduled disposal book information 221 in the highest priority group from the value of the item “rare value”, and then discards the scheduled book in the next highest priority group. The information to be discarded 223 is included in the third highest priority group including the information 222.

  Further, the sorting unit 258 includes the scheduled disposal information 224 in the fourth highest priority group from the value of the item “rare value prediction”.

  Further, for example, it is assumed that there are a plurality of scheduled disposal book information items whose item “rare value” is “not for sale”. In this case, the sorting unit 258 arranges the items to be disposed of in order starting from the information to be disposed of in order of the number of items in which the value is input among the items to be disposed of in the item “rare value” of “not for sale”.

  Specifically, in addition to the scheduled disposal information 221, the item “rare value” has a value of “not for sale”, and the items “rare value prediction” and “demand prediction” do not have a value to be discarded. Suppose that In this case, the sorting unit 258 sets the scheduled disposal information 221 in which the value of the item “demand prediction” exists in addition to the item “rare value” as information having higher priority.

  Next, with reference to FIG. 12, a list of planned disposal books output by the planned disposal book output unit 250 will be described. FIG. 12 is a diagram illustrating an example of a list of books to be discarded.

  The screen 121 illustrated in FIG. 12 may be a screen displayed on the terminal device 300, for example. The screen 121 includes an operation button 122 for instructing to output a list of books to be discarded, a list 123 of books to be discarded that are output in response to the output instruction, and a book database for reflecting book disposal in the library database 210. An operation button 124 is displayed.

  The list of book to be discarded 123 includes items “book ID”, “book name”, “rare value”, “rare value forecast”, and “demand forecast” among items of information included in the book to be discarded database 220. It is. In addition, the list of book to be discarded 123 includes an input field 125 for selecting whether or not to book the book to be discarded.

  In the list 123 of book to be discarded according to the present embodiment, books to be discarded are displayed in the order sorted by the sorting unit 258. That is, in the list 123 of books to be discarded, the books scheduled to be discarded are displayed in order from the book with the highest scarcity value.

  Furthermore, in the list 123 of the book to be discarded according to the present embodiment, the factors that are expected to increase the scarcity value of the book to be disposed of in the future, the events to be held in the future, and the relationship with the current attention are displayed. The

  As described above, according to the present embodiment, information relating to a book with limited circulation in the market is stored as scarce value information in the scarce value database 230, and the book to be discarded is referred to the scarce value database 230. The result collated with the database 220 is displayed.

  Therefore, according to this embodiment, based on objective information, librarians can predict future scarce value and demand for books to be discarded, and books that will become difficult to obtain in the future. It can suppress that it is discarded.

  In this embodiment, when a book to be discarded is selected from the collection and the book information to be discarded is stored in the book database 220 to be discarded, the rare value database 230 is referred to, and the selected book is to be discarded. You may make it determine whether it corresponds to a book.

  Hereinafter, the processing of the information processing apparatus 200 when storing the planned disposal book information in the planned disposal book database 220 will be described with reference to FIG. FIG. 13 is a fourth flowchart for explaining the operation of the information processing apparatus.

  The information processing apparatus 200 according to the present embodiment determines whether or not the input receiving unit 251 has received an input of a book ID of a book to be discarded (step S1301). If the input is not accepted in step S1301, the information processing apparatus 200 waits until the input is accepted.

  In step S1301, upon receiving the input of the book ID of the book to be discarded, the update unit 260 determines whether or not the book indicated by the input book ID is out of print (step S1302). Specifically, the update unit 260 determines whether or not the value of the item “state” of the rare value information including the ISBN corresponding to the input real ID is out of print in the rare value database 230.

  In step S1302, if it is not out of print, the update unit 260 proceeds to step S1305 described below. If it is out of print in step S1302, the update unit 260 refers to the rare value database 230 and acquires the number of books in stock corresponding to the input book ID (step S1303).

  Specifically, the updating unit 260 acquires the value of the item “stock quantity” of the scarce value information including the ISBN corresponding to the input book ID.

  Subsequently, the update unit 260 determines whether or not the acquired stock quantity is a predetermined number or more (step S1304). Specifically, for example, it is determined whether or not the number of stocks is two or more. The predetermined number may be an arbitrary number.

  In step S1304, when the number of stocks is equal to or larger than the predetermined number, the update unit 260 stores the information related to the book indicated by the input book ID as the scheduled disposal book information in the scheduled disposal book database 220 (step S1305). The process ends.

  If the stock quantity is less than the predetermined number in step S1304, the update unit 260 ends the process without storing the information related to the book indicated by the inputted book ID in the book database 220 to be discarded.

  That is, even if the facility manager such as a librarian selects a book as a book to be discarded even if a facility manager such as a librarian determines that the selected book has a high rare value, the update unit 260 stores information as a book to be discarded. Is not stored in the database to be discarded 220.

  Therefore, in this embodiment, when selecting a book to be discarded, it is possible to suppress a book having a high scarce value from being a book to be discarded, and it is possible to support selection of a book to be discarded.

  In the present embodiment, even when the book indicated by the inputted book ID is not for sale or when the selling price is higher than the regular price, information regarding this book is not stored in the to-be-discarded book database 220. Anyway.

  Further, in the present embodiment, information on books that may be discarded and information on books that should not be discarded (books with high rarity value) are displayed separately from the list 123 of books to be discarded. May be.

  FIG. 14 is a diagram illustrating a display example of information on books that may be discarded. On the screen 141 shown in FIG. 14, a list 142 of books that may be discarded is displayed.

  This list 142 is a book ID in which items “rare value”, “rare value prediction”, and “demand prediction” do not exist in the items of information included in the planned disposal database 220. This is information about the book specified.

  In addition, the list 142 includes information on books not to be discarded in the list 123 of books to be discarded.

  As described above, in the present embodiment, it is possible to identify the book that is easy to obtain as a book to be discarded or to display information on the identified book. In other words, in the present embodiment, a book whose degree of input difficulty satisfies the first condition may be specified as a book to be discarded and information regarding the specified book may be displayed. The first condition is that there are no values in all of the items “rare value”, “rare value prediction”, and “demand prediction” in the scheduled database 220.

  FIG. 15 is a diagram illustrating a display example of information related to a book with a high rare value. On the screen 151 shown in FIG. 15, a list 152 of books with high rare values (books that should not be discarded) is displayed.

  This list 152 has a value in any one of the items “rare value”, “rare value prediction”, and “demand forecast” among the items of information included in the planned disposal database 220. This is information relating to a book specified by an existing book ID.

  The list 152 includes information on the book selected as the book not to be discarded in the list 123 of books to be discarded.

  As described above, in the present embodiment, a book having a high rare value may be specified as a book that should not be discarded, and information regarding the specified book may be displayed. In other words, in the present embodiment, a book whose degree of input difficulty satisfies the second condition is identified as a book with high rare value that should not be discarded, and information on the identified book is displayed. Also good. The second condition is that a value exists in any one of the items “rare value”, “rare value forecast”, and “demand forecast” in the scheduled database 220.

  In the present embodiment, information on books that may be discarded is displayed or information on books that should not be discarded is displayed according to the degree of difficulty of acquisition. That is, according to the present embodiment, the degree of difficulty in obtaining is determined, and information on the book to be discarded is displayed according to the determination result.
