Summary of the Invention

Problems to be Solved by the Invention

[0004] A seller may plan to sell different quantities of stock at different prices at different times for a certain item. In this case, if the seller prepares in advance a plurality of sales information in which the basic content of the sales information for selling the item is the same and only a part is different, and only one of the plurality of sales information is made valid and the rest are made invalid, the sales information for the item can be immediately and easily switched.

[0005] New sales information copied from a certain sales information has the same basic content (the same product name and model number), so it is difficult to distinguish in a list. For this reason, there arises a problem that the sales information of a desired item cannot be immediately selected from the list.

[0006] The present invention solves the above problems and aims to easily present a list of a plurality of items with the same basic content but some differences for easy distinction.

Mode for Carrying Out the Invention

[0010] (Relationship between product information management server, terminal, and program) The product information management server according to this embodiment is composed of one or more server devices. The product information management server manages information (hereinafter also referred to as product information) regarding items handled by users who use terminals such as smartphones, tablet computers, and personal computers. The product information management server presents a list of items in response to user operations, and registers, edits, etc. product information.

[0011] The product information management server according to this embodiment can be used, for example, when providing means for managing items to be offered by sellers who enter the electronic market.

[0012] Now, although the product information management server of this embodiment is generally realized by causing a computer to execute a program, it is also possible to execute processing by a dedicated electronic circuit.

[0013] In addition, as an intermediate form of a dedicated electronic circuit of a computer, by applying technologies such as FPGA (Field Programmable Gate Array) that compiles a program into a design script of an electronic circuit and dynamically configures an electronic circuit based on the design script, it is also possible to configure the product information management server of this embodiment.

[0014] The product information management server according to this embodiment is realized by one or more server computers that communicate with a terminal accessing a product information management site provided by the product information management server, executing each function realized by one or more server programs.

[0015] The terminal according to this embodiment is a terminal computer that realizes a smartphone or the like, and can be realized by executing a terminal program provided from a distributor server or the like by an operator or an operator.

[0016] As the terminal program, something corresponding to a so-called "App" can be adopted. Also, the terminal program may be incorporated into other apps such as an app for providing an Internet sales service.

[0017] In addition, as the terminal program, a general browser can be adopted, or a script program operating on the browser can be adopted as the terminal program.

[0018] In these cases, an app or browser operating on the terminal computer serves as an interface for providing a product information management service to the user by communicating with the product information management server that functions as an app server or a web server.

[0019] Generally, programs executed on a server computer or a terminal computer can be recorded on a computer-readable non-transitory information recording medium such as a compact disk, a flexible disk, a hard disk, a magneto-optical disk, a digital video disk, a magnetic tape, a ROM (Read Only Memory), an EEPROM (Electrically Erasable Programmable ROM), a flash memory, a semiconductor memory, etc. This information recording medium can also be distributed and sold independently of the server computer.

[0020] On a server computer or a terminal computer, a program recorded on a non-transitory information recording medium such as a flash memory or a hard disk is read into a RAM (Random Access Memory) which is a temporary storage device, and then the CPU (Central Processing Unit) executes the instructions included in the read program. However, in an architecture where it is possible to map RAM and ROM to one memory space and execute, the CPU directly reads and executes the instructions included in the program stored in ROM.

[0021] Furthermore, server programs and terminal programs can be distributed and sold from distribution servers or the like managed by a business operator or an operator to server computers, terminal computers, etc. via a temporary transmission medium such as a computer communication network, independently of the computer on which the program is executed.

[0022] In addition, when the product information management server is composed of a plurality of computers, the programs operating on each computer are a plurality of different server programs that cooperate while having different functions. Therefore, the combination of the plurality of programs can be considered as a system program for realizing the product information management server.

[0023] Hereinafter, in the present embodiment, the product information management server provides an electronic market, presents a list of item information which is information on items listed in the electronic market, and provides means for registering, editing, etc. item information.

[0024] (Overall Configuration) FIG. 1 is an explanatory diagram showing the cooperation between the product information management server 101 and other devices. Hereinafter, description will be made with reference to this figure.

[0025] The product information management server 101 is connected via a computer communication network 103 such as the Internet to one or more terminals 102. Note that the product information management server 101 and one or more terminals 102 may be connected by various networks such as a line.

[0026] The product information management server 101 is operated by a business operator or an operator who provides an electronic market, and provides means for managing item information regarding items to be listed by users who are sellers using the terminal 102 via the computer communication network 103. Item information is, for example, product name, model number, selling price, stock quantity, sales period, color, and size.

[0027] The terminal 102 is a terminal used by a user who offers products in the electronic market provided by the product information management server 101. The user uses the terminal 102 to perform operations such as presenting a list of item information regarding the items offered by the user, registering and editing item information.

[0028] (Functional Configuration of Product Information Management Server) FIG. 2 is an explanatory diagram showing the functional configuration of the product information management server 101. The product information management server 101 includes a product information registration database (DB) 110, an extraction unit 120, a list presentation unit 130, a specification unit 140, an item registration unit 150, and an editing unit 160.

[0029] The product information registration DB 110 is a database in which detailed information on items handled by each user who offers products in the electronic market is registered. Here, "each user" may indicate each store that offers products. FIG. 3 is an example of a product information record related to items handled by the provider P. Each item information includes items such as line number (#i), product name, model number, selling price, stock quantity, sales period, color, size, and copy flag. In this example, it is assumed that N products handled by the provider P are registered in the product information registration DB 110. The copy flag is an example of copy status information. Note that the product information registration DB 110 may associate the identification information of the user with the detailed information of the item.

[0030] The line number is a number assigned to a row of the product information record, and each item is assigned in the order sorted according to a predetermined criterion. Here, sorting according to a predetermined criterion means sorting each item in the order of 50 - sound order, alphabetical order, or numerical order, and it may be made possible for the user to set. The copy flag is a flag indicating that the item information is registered by copying other item information in an editing operation by the user. A copy flag of "0" is assigned to newly registered item information, and a copy flag of "1" is assigned to item information copied from other item information.

[0031] In this embodiment, in the product information record, the content of each item in each item information is referred to as detailed information DEI. For example, as shown in FIG. 3, the detailed information DEI is the part of each product information record excluding the line number. Note that the detailed information DEI may also be the entire product information record. Note that the product information registration DB 110 may not store the line number. In this case, the product information management server 101 may search for a plurality of detailed information DEIs from the product information registration DB 110, sort them based on a predetermined part of the searched detailed information DEI, assign a line number to the sorted result, and output it to the terminal 102. Also, in each item information, a predetermined part such as a product name and a model number indicating the outline of the item is referred to as outline information OI, and other predetermined parts such as a selling price and an inventory number that are useful for the user to judge the content of the item are referred to as reference information RI. Here, the outline information OI is information that can identify the product. For example, the outline information OI is information that can identify the purchase target. Also, the reference information RI is information that can identify the characteristics of the product. Also, the reference information RI is also referred to as information indicating the management status of the product. For example, the reference information RI is information that identifies what can vary depending on the selling time among information representing the characteristics of the purchase target, such as the selling price and the inventory number.

[0032] Returning to FIG. 2, the extraction unit 120 extracts a predetermined part from the detailed information DEIs of a plurality of items registered in the product information registration DB 110 as outline information OI. The extraction unit 120 extracts the product name or the model number as the predetermined part as the outline information OI. Also, the extraction unit 120 further extracts other predetermined parts from the detailed information DEIs of a plurality of items registered in the product information registration DB 110 as reference information RI. The extraction unit 120 extracts the selling price and the inventory as the other predetermined parts as the reference information RI. The items extracted as the outline information OI and the reference information RI are assumed to be set in advance by a user operation or the like.

[0033] The list presentation unit 130 outputs a list of the summary information OI arranged by the extraction unit 120 to the terminal 102. For example, the list presentation unit 130 presents, via the terminal 102, a list of the summary information OI arranged by the extraction unit 120 to the user. Further, when the summary information OI of each of the plurality of detailed information is common, the list presentation unit 130 outputs information such as differences. Details will be described later.

[0034] When the first summary information extracted from the first detailed information of the first item among the plurality of items in the product information record matches the second summary information extracted from the second detailed information of the second item, the specific unit 140 specifies the different parts between the first detailed information and the second detailed information.

[0035] The item registration unit 150 receives, via the terminal 102, an operation of registering information of a new item in the product information record from the user.

[0036] The editing unit 160 receives, via the terminal 102, an operation of editing the detailed information DEI of the item information included in the product information record from the user. Further, the editing unit 160 receives an operation of copying the item information included in the product information record from the user.

[0037] (Interaction between the product information management server and the terminal) FIG. 4 is a sequence diagram showing the state of interaction between the product information management server 101 and the terminal 102. Hereinafter, with reference to FIG. 4, an outline of the interaction between the product information management server 101 and the terminal 102 will be described.

[0038] First, when the user performs a list display operation for displaying a list of items handled by the user (301), the terminal 102 transmits a list presentation request specifying information (identification information) for identifying the user to the product information management server 101 (302). In the following processes, when the terminal 102 performs various request processes to the product information management server 101, the identification information of the user of the terminal 102 is also transmitted.

[0039] When the product information management server 101 receives a list display request from the terminal 102, it accesses the product information registration DB 110 and refers to the user's product information record related to the information specified in the list display request. Then, the extraction unit 120 extracts the overview information OI and the reference information RI from the user's product information record (303).

[0040] After that, the list display unit 130 creates a list L by arranging the overview information OI and the reference information RI extracted by the extraction unit 120 (304), and transmits a list display response specifying the list L to the terminal 102 (305).

[0041] When the terminal 102 receives the list display response, it displays the list L specified in the list display response (306). FIG. 5 is an example of a list display screen 400 displayed on the terminal 102. On the list display screen 400, a list L, a new registration button 401, an edit button 402, and a copy button 403 are displayed. The edit button 402 and the copy button 403 are respectively displayed on the right side of each item information outside the list L.

[0042] Returning to FIG. 4, here, when the user selects the new registration button 401 (307), the terminal 102 transmits an item registration request for newly registering item information to the product information management server 101 (308). When the product information management server 101 receives the item registration request, the item registration process starts (309), and an item information registration screen 500 shown in the example of FIG. 6 is displayed on the terminal 102. On the item information registration screen 500, an input field 501 for inputting detailed information DEI and a registration button 502 are displayed. When the user edits the input field 501 (331) and selects the registration button 502, the item information is registered and the item registration process ends.

[0043] Then, the product information management server 101 transmits an item registration completion response specifying the list L after item registration to the terminal 102 (310). When the terminal 102 receives the item registration completion response, it displays the list L specified in the item registration completion response (311). The newly registered item information is added to this list L.

[0044] Subsequently, as shown in FIG. 7, when the user selects the edit button 402 of line number 2 (312), the terminal 102 sends an edit request to the product information management server 101 to edit the item information (313). When the product information management server 101 receives the edit request, the edit process starts (314), and an edit screen 700 as shown in FIG. 8 is displayed on the terminal 102. In the edit screen 700, the detailed information DEI of line number 2 can be edited. When the user edits the input field 701 (332) and selects the save button 702, the edited item information is registered and the edit process ends.

[0045] Then, the product information management server 101 sends an edit completion response specifying the list L after editing to the terminal 102 (315). When the terminal 102 receives the edit completion response, it displays the list L specified in the edit completion response (316). The edited item information is displayed in this list L.

[0046] Subsequently, as shown in FIG. 9, when the user selects the copy button 403 of line number 2 (317), the terminal 102 sends a copy request to the product information management server 101 to copy the item information (318). When the product information management server 101 receives the copy request, the copy process starts (319), and a copy screen 800 as shown in the example of FIG. 10 is displayed on the terminal 102.

[0047] On the copy screen 800, the item information copied from the item at line number 2 can be edited. Also, on the copy screen 800, some input fields 801 such as the selling price and the inventory quantity may be left blank. Furthermore, the start date of the selling period may be set to the day after the end date of the selling period of the original item (in this example, December 23, 2023 to January 7, 2024), which is January 8, 2024, and the end date may not be specified. In this way, by leaving blank the items that tend to be edited after the copy operation or specifying predetermined contents, the convenience of the user can be improved. Note that for the items that tend to be edited after the copy operation, the information of the copy source may be displayed in another column on the copy screen as reference information for editing.

[0048] When the user edits the input field 801 (333) and selects the save button 802, the item information after the copy is registered and the copy process ends. Note that the editing unit 160 sets the copy flag in the item information after the copy to "1" and registers it in the product information registration DB 110. Then, the product information management server 101 transmits a copy completion response specifying the list L with the copied item information added to the terminal 102 (320).

[0049] When the terminal 102 receives the copy completion response, it displays the list L specified in the copy completion response (321). As shown in FIG. 11, in this list L, the item information after the copy (line number 3) is added directly below the item information before the copy (line number 2). In the example of FIG. 11, the difference between the item at line number 2 and the item at line number 3 cannot be immediately discerned, but in this embodiment, a device is incorporated to facilitate the discrimination of the items before and after the copy. Details will be described later.

[0050] (Product Information Management Process) FIG. 12 is a flowchart for explaining the flow of product information management processing executed by the product information management server 101 in the present embodiment. The product information management server 101 presents to the user via the terminal 102 in a manner that makes it easy to distinguish the differences between similar items within a list L in which a plurality of items are arranged. Hereinafter, description will be made with reference to FIG. 12.

[0051] The product information management processing starts when the product information management server 101 receives a list presentation request specifying information (similar to the above-described user identification information) for specifying the user from the terminal 102 used by the seller P who is the user. When the product information management processing starts, the extraction unit 120 accesses the product information registration DB 110 and refers to the product information record of the seller P shown in the example of FIG. 13(a). The extraction unit 120 first extracts the product name and model number, which are predetermined parts (step S801). Here, the extracted predetermined parts are used as the outline information OI.

[0052] Thereafter, the extraction unit 120 further extracts other predetermined parts from the detailed information DEI of the plurality of item information registered in the product information registration database (step S802). Here, the extraction unit 120 extracts the selling price and the stock quantity as other predetermined parts. Note that the extraction unit 120 may extract the outline information OI and the reference information RI together.

[0053] Subsequently, the list presentation unit 130 creates a list in which the extracted outline information OI and reference information RI are arranged as shown in the example of FIG. 13(b) (step S803). That is, the list presentation unit 130 further presents the reference information RI extracted from the same detailed information DEI as each outline information OI in association with each outline information OI in the list. Thereafter, the list presentation unit 130 sets the line number i for comparison target to 1 (step S804).

[0054] After that, the specifying unit 140 searches for item information in the created list that matches the item information and the summary information OI at the line number i = 1 of the comparison reference (step S805), and determines whether there is item information (first item) that matches the item information at the line number i = 1 of the comparison reference and the summary information OI (second item) (step S806). That is, the specifying unit 140 determines whether the first summary information OI extracted from the first detailed information DEI of the first item matches the second summary information OI extracted from the second detailed information DEI of the second item.

[0055] If the specifying unit 140 determines that there is no item information that matches the item information and the summary information OI at the line number i = 1 of the comparison reference (No in step S806), the product information management server 101 determines whether the item information currently being calculated is the last item information, that is, whether the line number i is i = N (step S807). Since the item information currently being calculated is the item information at the line number i = 1, the product information management server 101 determines that the line number i of the comparison reference is not i = N (No in step S807), and increments the line number i of the comparison reference (step S808). After that, the process proceeds to step S805.

[0056] Here, if one of the two detailed information DEI that match the summary information OI extracted by the extraction unit 120 is caused by copying the other of the two detailed information DEI, the specifying unit 140 may use the other as the first detailed information DEI and the one as the second detailed information DEI. That is, the specifying unit 140 may use, as the first detailed information DEI, the one with the copy flag of 0 among the detailed information DEI that match the summary information OI, and use, as the second detailed information DEI, the one with the copy flag of 1.

[0057] On the other hand, when the specific part 140 determines that there is item information (second item) that matches the item information (first item) with the line number i = 1 of the comparison reference and the outline information OI (Yes in step S806), it determines whether there are different parts in the detailed information DEI of the two item informations (step S809). That is, the specific part 140 determines whether there are different parts between the first detailed information DEI of the first item and the second detailed information DEI of the second item.

[0058] When the specific part 140 determines that there are different parts in the detailed information DEI of the two item informations (Yes in step S809), the list presentation part 130 adds difference information DII (step S810). Here, the list presentation part 130 presents the second difference information DII related to the different parts of the second detailed information DEI together with the second outline information OI arranged in the list. For example, in the case of the list display screen 400 shown in FIG. 14, the second difference information DII indicating that the sales periods are different is presented on the left side of the product name of the item information (second item) with the line number 3 copied from the item information (first item) with the line number 2. In addition, when the item information is a copy, the fact that it is a copy may be included in the second difference information DII. Further, information for specifying the item information of the copy source may be added.

[0059] In addition, the list presentation part 130 may further present the first difference information DII related to the different parts of the first detailed information DEI together with the first outline information OI arranged in the list. For example, as in the list display screen 400 shown in FIG. 15, the second difference information DII is presented for the item information with the line number 3 which is the second item, and the first difference information DII is presented on the left side of the product name of the item with the line number 2 which is the first item. Here, the sales period of the first item may be displayed in the first difference information DII, and the sales period of the second item may be displayed in the second difference information DII.

[0060] In addition, as shown in the example of FIG. 16, the list presentation part 130 may display the first difference information DII and the second difference information DII in the column of the product name which is the outline information OI.

[0061] Return to FIG. 12. On the other hand, if the specific part 140 determines that there are no different parts in the detailed information DEI of the two item information (No in step S809), the list presentation unit 130 adds warning information WI (step S810). That is, when the specific part 140 cannot identify different parts, the list presentation unit 130 presents the first warning information WI together with the first summary information OI, and presents the second warning information WI together with the second summary information OI.

[0062] FIG. 17 is an example of a list display screen 400 when the specific part 140 cannot identify different parts between the detailed information DEI of the item information in the m-th row and the detailed information DEI of the item information in the n-th row. When the first summary information is in the m-th position and the second summary information is in the n-th position in the list, the first warning information WI may indicate that the content is the same as the item information in the n-th row, and the second warning information WI may indicate that the content is the same as the item information in the m-th row. Also, as shown in the example of FIG. 18, the list presentation unit 130 may display the first warning information WI and the second warning information WI in the column of each product name. Then, the process proceeds to step S807.

[0063] Return to FIG. 12. Subsequently, the specific part 140 determines whether the difference information DII is included in the reference information RI (step S812). If the specific part 140 determines that the difference information DII is included in the reference information (Yes in step S812), the list presentation unit 130 highlights the difference information (step S813). That is, if the second difference information DII is included in the second reference information RI extracted from the second detailed information DEI, the list presentation unit 130 highlights the second difference information DII included in the second reference information RI in the list, and presents the second difference information DII together with the second summary information OI.

[0064] FIG. 19 shows an example of a list display screen 400 when the selling price, which is the difference information DII of the item information (second item) on line number 4 copied from the item information (first item) on line number 2, is included in the reference information RI. The list presentation unit 130 displays the second difference information DII on the left side of the product name, which is the second summary information OI of the second item. At this time, the list presentation unit 130 may display the selling prices of the item information on line number 2 and the item information on line number 4 as the difference information DII. Also, as shown in the example of FIG. 20, the list presentation unit 130 may display the difference information DII within the column of the product name, or may display the first difference information DII within the column of the product name of the first item and the second difference information DII within the column of the product name of the second item. Note that the list presentation unit 130 may emphasize and display the selling price parts of line number 2 and line number 4 as the difference information.

[0065] Thereafter, the process proceeds to step S807. The product information management server 101 determines whether the item information currently being calculated is the last item information, that is, whether line number i is i = N (Yes in step S807). If so, it transmits a list presentation response specifying the created list L to the terminal 102 and ends the process.

[0066] As described above, according to this embodiment, in a list table arranging a plurality of item information with the same basic content and some differences, the specifying unit 140 specifies the different parts, and the list presentation unit 130 presents the different parts. Thereby, for example, even for items that are indistinguishable at a glance by a copy operation, the user can distinguish them without performing a special operation.

[0067] (Modification example) In the above-described embodiment, among the items of the product information record shown in the example of FIG. 3, a line number was adopted as the item assigned to the record. However, in addition to the line number, a record number for identifying item information may be adopted. The line number may shift when new item information is added between lines or specific item information is deleted by a copy operation or the like. However, since the record number is assigned to the item information itself, it does not shift due to these operations.

[0068] Also, in the above-described embodiment, a copy flag of "0" is assigned to the item information before copying and "1" is assigned to the item information after copying. However, as the number of copies increases, the value of the copy flag may be increased. In this case, for example, when copying item information with a copy flag of "1", item information with a copy flag of "2" is added to the list L. Thereby, the specific part 140 can discriminate between the first item and the second item based on the magnitude of the copy flag, and the list presentation unit 130 can clarify the correspondence between the first item and the second item and present the difference information DII. Furthermore, the record number of the copy source may be input to the copy flag. Thereby, the list presentation unit 130 can clarify the correspondence between the first item and the second item and present the difference information DII.

[0069] Also, in the above-described embodiment, the case of using copy flag information has been described. However, as copy status information, not only whether it is a copy but also the information of the copy source may be included. Thereby, the parent-child relationship regarding the copy of each product information record can be defined. Also, such information indicating the parent-child relationship of the copy may be displayed and output as difference information.

[0070] Also, in the above-described embodiment, the case of displaying and outputting summary information, reference information, and difference information has been described.
