  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. The embodiment described below is an embodiment when the present invention is applied to a C2C (Customer to Customer) online market system in which merchandise is bought and sold at a price determined by the seller. The present invention can also be applied to electronic commerce such as auction, B2C (Business-to-Consumer), B2B (Business-to-Business).

[1. Overview of market system configuration and functions]
First, the configuration and functional overview of the market system S according to the present embodiment will be described with reference to FIG. FIG. 1 is a diagram illustrating an example of a schematic configuration of a market system S according to the present embodiment.

  As shown in FIG. 1, the market system S includes a market server 1 and a plurality of user terminals 2. And the market server 1 and each user terminal 2 can mutually transmit / receive data via the network NW, for example using TCP / IP etc. as a communication protocol. The network NW is constructed by, for example, the Internet, a dedicated communication line (for example, a CATV (Community Antenna Television) line), a mobile communication network (including a base station), a gateway, and the like.

  The market server 1 is a server device that executes various processes related to electronic commerce for buying and selling products between users in the market system S. The user can sell the product and purchase the product. In the market system S, various types of merchandise can be bought and sold. For example, commodities that can be bought and sold may include at least one of clothes, books, CDs, DVDs, toys, furniture, bags, accessories, beauty supplies, electrical appliances, and the like. In the following, the buying and selling of clothes will be mainly described.

  The user terminal 2 is a terminal device of a user who uses the market system S. As the user terminal 2, for example, a personal computer, a PDA (Personal Digital Assistant), a portable information terminal such as a smartphone, a mobile phone, a game machine, or the like is used. The user terminal 2 stores a market application. The market application is an application program for causing the user terminal 2 to execute processing for the user to perform product listing, search, purchase, and the like. By executing the market application, the user terminal 2 accesses the market server 1 and transmits / receives information to / from the market server 1.

  When the user sells a product, the product information is registered in the market system S. The user uploads the product image to the market server 1 by the user terminal 2. The product image is an image representing a product. For example, when the user terminal 2 has a camera function, the user may photograph a product with the user terminal 2. Alternatively, the user may transfer a product image taken by the digital camera from the digital camera to the user terminal 2. The user also selects a product category. Furthermore, the user inputs a product name, a product description, a price, and the like. The product name is the title of the product or product information. The product description indicates a description of the product. The market server 1 stores product information including a product image, a category ID indicating a product category, a product name, a product description, a price, and the like in a product DB 12d described later.

[2. Market server configuration]
Next, the structure of the market server 1 is demonstrated using FIG.2 and FIG.3. FIG. 2 is a block diagram illustrating an example of a schematic configuration of the market server 1 according to the present embodiment. As shown in FIG. 2, the market server 1 includes a communication unit 11, a storage unit 12, an input / output interface 13, and a system control unit 14. The system control unit 14 and the input / output interface 13 are connected via a system bus 15.

  The communication unit 11 is connected to the network NW and controls the communication state with the user terminal 2 and the like.

  The storage unit 12 is configured by, for example, a hard disk drive. The storage unit 12 is an example of attribute storage means and product information storage means in the present invention. The storage unit 12 stores databases such as a member DB 12a, a category DB 12b, an attribute value DB 12c, and a product DB 12d. “DB” is an abbreviation for database.

  FIG. 3 is a diagram illustrating an example of contents stored in the database. In the member DB 12a, member information related to users registered as members in the market system S is stored. Specifically, user attributes such as user ID, password, name, postal code, address, telephone number, and e-mail address are stored in the member DB 12a in association with each user. The user ID is user identification information.

  The category DB 12b stores category information related to categories for classifying products. Specifically, the category DB 12b stores category attributes such as category ID, category name, category level, parent category ID, child category list, and attribute list in association with each category.

  Categories may be defined hierarchically in a tree structure. Specifically, each node of the tree structure corresponds to a category. The depth of the node corresponds to the level (hierarchy) of the category corresponding to the node. The depth of the node is a distance from a node located at the root (hereinafter referred to as “root node”). The larger the level value, the deeper the node, and the smaller the level value, the shallower the node. A category corresponding to a child node of the root node is a level 1 category. Level 1 category is the highest category. For each level 1 category, a category corresponding to a child node is defined as a level 2 category. Here, the category J2 corresponding to a child node of a certain category J1 is referred to as a “child category” of the category J1. The category J1 at this time is referred to as a “parent category” of the category J2. The child category is a range to which similar products belong when the parent category is further divided into a plurality of categories. Therefore, the child category belongs to the parent category. A category corresponding to an ancestor node of a certain category is referred to as an “ancestor category”. For example, assume that category J3 is a child category of category J2. In this case, the categories J1 and J2 are ancestor categories of the category J3. The product of category J3 belongs to category J3 and also belongs to the ancestor category of category J3. Therefore, the product of category J3 belongs to any of categories J1 to J3. A category corresponding to a descendant node of a certain category is referred to as a “descendant category”. Categories J2 and J3 are descendant categories of category J1.

  Level 1 categories include, for example, “Ladies Fashion”, “Kids / Baby”, “Men's Fashion”, “Hobby Entertainment”, and the like. Child categories of “Women's Fashion” include “Tops”, “Skirt”, “Pants”, “Jacket / Outerwear”, “Others”, etc. Products that belong to “Ladies' fashion” but do not belong to a specific category such as “Tops”, “Skirt”, “Pants”, “Jacket / Outer” are classified as “Other”. Child categories of “Tops” include, for example, “T-shirts”, “Shirts / blouses”, “Polo shirts”, “Tunics”, “Others”, and the like.

  The category ID is identification information of the category of interest. The category ID is an example of category information indicating a category. The category names are “tops”, “one piece”, and the like. The parent category ID is the category ID of the parent category of the category of interest. The child category list is a list of category IDs of child categories of the category of interest. The child category list is stored when the category of interest has child categories.

  The attribute list is a list of attribute names of attributes of products belonging to the category of interest. For example, attribute names included in the attribute list of categories belonging to “Ladies' fashion” and “Men's fashion” include “shape”, “color”, “pattern”, “size”, “material”, “brand” “Coordinate examples” and the like. Examples of attribute names included in the attribute list of the category belonging to “Tops” include “length”, “shoulder width”, “width of the body”, “sleeve length”, and the like in addition to the attribute names described above. Examples of attribute names included in the attribute list of the category belonging to “skirt” include “waist size”, “skirt length” and the like in addition to the attribute names described above.

  The attribute value DB 12c stores information on attribute values corresponding to product features that can be extracted from the product image. Specifically, the attribute value DB 12c stores an attribute value, an attribute name, a feature amount, and the like in association with each attribute value. The attribute name is the name of the attribute corresponding to the attribute value. Examples of attribute names stored in the attribute value DB 12c include “shape”, “color”, “pattern”, “material”, “brand”, and the like. Examples of attribute values corresponding to “shape” include “T-shirt”, “shirt”, “blouse”, “polo shirt”, “tunic”, and the like. Examples of attribute values corresponding to “color” include “red”, “white”, “yellow”, “black”, “red-white”, “white-red”, and the like. “Red-white” and “white-red” indicate that the product color includes red and white. In “red and white”, the red area is larger than the white area. In “white red”, the white area is larger than the red area. Examples of attribute values corresponding to “pattern” include “plain”, “check”, “stripe”, “border”, “polka dot”, “picture”, and the like. Examples of attribute values corresponding to “material” include “cotton” and “knit”. As for “brand”, for example, a corresponding attribute value may be specified from a logo, a pattern, or the like attached to a product. As the attribute name, the attribute name of a predetermined element that the product may have may be further stored in the attribute value DB 12c. For example, there is a case where an element that is not necessarily possessed by a product belonging to a predetermined category is attached to the product. An example of such an element is a picture. Among products belonging to the same category, there are products with a picture and products without a picture. An example of an attribute name related to a picture is “picture motif”. The picture motif may be, for example, some character, landscape, thing, person, or the like. The picture in this case is specified as one of the above patterns. The feature amount is information indicating the feature of the attribute value of interest in the image. For example, by analyzing a typical image having a feature indicated by the attribute value, the feature amount may be extracted from the image. For example, the feature amount may be extracted using a known method. For example, an algorithm such as SIFT (Scale Invariant Feature Transform), SURF (Speeded Up Robust Features), or a deep neural network such as CNN (Convolutional Neural Network) may be used.

  In the product DB 12d, product information related to products that have been exhibited in the market system S is stored. In the product DB 12d, a product ID, a user ID, a category ID, a product image, a price, a product name, a product description, an exhibition state, and the like are stored in association with each product. The product ID is product identification information. The user ID indicates a user who sells a product. The category ID indicates the category to which the product belongs. The category ID stored in the product DB 12d may be, for example, the category ID of the lowest category. In the exhibition state, any of “being exhibited”, “sales completed”, and “exhibition canceled” is stored. “Exhibiting” indicates that the item is being exhibited. “Buy / sell” indicates that the sale of the product has been established. “Exhibition stop” indicates that a product has been exhibited once, but the user has canceled the exhibition for some reason.

  The storage unit 12 further stores various programs such as an operating system, a DBMS (Database Management System), and a server program. The server program is a program that causes the system control unit 14 to execute various processes related to the market system S. The various programs may be acquired from, for example, another server device or the like via the network NW, or may be recorded on a recording medium such as a magnetic tape, an optical disk, or a memory card and read via the drive device. You may be made to do. The server program or the like may be a program product.

  The input / output interface 13 performs interface processing between the communication unit 11 and the storage unit 12 and the system control unit 14.

  The system control unit 14 includes a CPU (Central Processing Unit) 14a, a ROM (Read Only Memory) 14b, a RAM (Random Access Memory) 14c, and the like. The CPU 14a is an example of a processor. The present invention can also be applied to various processors different from the CPU. Each of the storage unit 12, the ROM 14b, and the RAM 14c is an example of a memory. The present invention can also be applied to various memories different from the hard disk, ROM, and RAM.

  The market server 1 may be composed of a plurality of server devices. For example, a server device that performs processing related to product listing in the market system S, a server device that performs processing for providing product information to the user terminal 2, a server device that manages a database, and the like may be connected to each other via a LAN or the like.

[3. Overview of system control functions]
Next, the functional outline of the system control unit 14 will be described with reference to FIGS. 4 to 11. FIG. 4 is a diagram illustrating an example of functional blocks of the system control unit 14 of the market server 1 according to the present embodiment. As shown in FIG. 4, the system control unit 14 reads and executes various program codes included in a program such as a server program by the CPU 14 a, so that an image / category acquisition unit 141, an attribute list acquisition unit 142, an attribute value specification Functions as a unit 143, a presentation control unit 144, a product information registration unit 145, and the like. The image / category acquisition unit 141 is an example of an image information acquisition unit in the present invention. The attribute list acquisition unit 142 is an example of a list acquisition unit in the present invention. The attribute value specifying unit 143 is an example of specifying means in the present invention. The presentation control unit 144 is an example of a presentation control unit in the present invention. The merchandise information registration unit 145 is an example of a storage control unit in the present invention.

  A user who wants to sell a product is called an “exhibitor”. When listing a product, the exhibitor uploads a product image and registers information about the product. It takes time and effort for the exhibitor to manually register all the various information related to the product. Therefore, the system control unit 14 specifies the attribute value of the product based on the product image. The attribute value specified based on the product image is referred to as “first attribute value”. The system control unit 14 causes the user terminal 2 to present an attribute that does not correspond to the first attribute value. The system control unit 14 acquires the attribute value input by the exhibitor in response to this presentation. This attribute value is referred to as a “second attribute value”. The system control unit 14 stores product information including the first attribute value and the second attribute value in the product DB 12d. I want to register as many attributes as possible for all products in the same category. Therefore, for each category, an attribute list indicating the attributes of the products belonging to the category is prepared in advance. Then, the system control unit 14 registers the attribute value information that can be specified from the product image without the user's input, and in the attribute list, the remaining attribute whose attribute value is not specified from the product image is displayed to the user. Prompt for attribute value. Thereby, the exhibitor need not input the first attribute value specified from the product image, and can register a lot of information including the first attribute value and the second attribute value.

  The image / category acquisition unit 141 acquires a product image representing a product and a category ID of the product. Specifically, the image / category acquisition unit 141 acquires a product image uploaded from the user terminal 2 of the exhibitor. The image / category acquisition unit 141 may acquire only one product image or may acquire a plurality of product images. The image / category acquisition unit 141 may acquire a category ID from the user terminal 2 of the exhibitor. For example, the user terminal 2 displays a screen for selecting a category. The user terminal 2 transmits the category ID of the category selected by the exhibitor to the market server 1. Alternatively, the image / category acquisition unit 141 may acquire the category ID based on the first attribute value specified from the product image by the attribute value specifying unit 143 described later. For example, when the first attribute value corresponding to the shape is specified from the product image, the image / category acquisition unit 141 may search the category DB 12b for a category name that matches the first attribute value. The image / category acquisition unit 141 may acquire a category ID corresponding to the category name that matches the first attribute value from the category DB 12b. Alternatively, the image / category acquisition unit 141 may cause the user terminal 2 to present a plurality of candidates for the product category based on the result of specifying the first attribute value from the product image by the attribute value specifying unit 143. The image / category acquisition unit 141 may acquire the category ID of the category selected by the exhibitor from the candidates from the user terminal 2.

  FIG. 5 is a diagram illustrating an example of an outline of processing by the system control unit 14. As shown in FIG. 5, it is assumed that the product image acquired by the image / category acquisition unit 141 represents the tunic P1. The image / category acquisition unit 141 acquires a category ID of “tunic” of “tops” of “ladies fashion” based on, for example, selection of an exhibitor.

  The attribute list acquisition unit 142 acquires an attribute list corresponding to the category ID acquired by the image / category acquisition unit 141 from the category DB 12b. In the example illustrated in FIG. 5, the attribute list acquisition unit 142 acquires an attribute list corresponding to the category ID “tunic”.

  The attribute value specifying unit 143 specifies the first attribute value of the product from the product image acquired by the image / category acquisition unit 141. For example, the attribute value specifying unit 143 specifies the first attribute value indicating the feature of the product through image recognition. For example, the attribute value specifying unit 143 extracts one or more feature amounts from the product image. For example, an algorithm such as SIFT or SURF or a deep neural network may be used for extracting the feature amount. The attribute value specifying unit 143 may extract a feature amount for each attribute such as a shape, a color, a pattern, and a material. The attribute value specifying unit 143 compares the extracted feature quantity with the feature quantity stored in the attribute value DB 12c, and calculates the similarity of the feature quantity. For example, the attribute value specifying unit 143 may calculate a cosine similarity, a correlation function, a deviation pattern similarity, or the like. The attribute value specifying unit 143 may specify the attribute value having the highest similarity among the attribute values corresponding to the attribute as the first attribute value. The attribute value specifying unit 143 may not specify the first attribute value for the attribute when the attribute value corresponding to the attribute does not include an attribute value with a similarity equal to or greater than the predetermined value. The attribute value specifying unit 143 may specify a character string attached to the product from the product image by character recognition, for example, and may specify the first attribute value corresponding to the brand based on the character string. Multiple product images may be uploaded. In this case, the attribute value specifying unit 143 may specify the first attribute value, for example, from the product image uploaded first. Alternatively, the attribute value specifying unit 143 may specify the first attribute value from each of the plurality of product images, and determine the most appropriate first attribute value based on each specifying result. As this determination method, for example, there is a method in which the attribute value specified from each of two or more product images among a plurality of product images overlaps with each other, that is, the attribute value is determined as the first attribute when there are two or more times.

  In the example shown in FIG. 5, “tunic” corresponding to the shape, “red and white” corresponding to the color, “border” corresponding to the pattern, and “knit” corresponding to the material are specified as the first attributes. Depending on the characteristics of the image, for example, the material or other attributes may not be specified, or more attributes than the above four attributes may be specified.

  The presentation control unit 144 causes the user terminal 2 to present an attribute that does not correspond to the first attribute value specified by the attribute value specifying unit 143 among the attributes included in the attribute list acquired by the attribute list acquiring unit 142. The attribute corresponding to the first attribute value is referred to as “first attribute”, and its name is referred to as “first attribute name”. The attribute corresponding to the second attribute value is called “second attribute”, and the name is called “second attribute name”. The presentation control unit 144 may cause the user terminal 2 to display the attribute name of the second attribute on the product information input screen. The product information input screen is a screen for inputting information related to the product to be exhibited.

  In the example shown in FIG. 5, the tunic attribute list includes “shape”, “color”, “pattern”, “material”, “size”, and “coordinate example”. In this case, the attribute names of the second attribute that do not correspond to the first attribute value are “size” and “coordinate example”.

  FIG. 6 is a diagram illustrating an example of a product information input screen. The product information input screen includes a product name input area 110, a product description input area 120, a price input area 130, an exhibition button 140, and the like. The product name input area 110 is an area for inputting a product name. The product description input area 120 is an area for inputting a product description. The price input area 130 is an area for inputting a price. The exhibition button 140 is a button for listing products by registering product information.

  The first attribute value specified by the attribute value specifying unit 143 may be input in advance in at least one of the product name input area 110 and the product description input area 120. Thereby, the exhibitor can save the trouble of inputting the first attribute. In the example illustrated in FIG. 6, the first attribute value is input in the product description input area 120. In association with the input first attribute value, at least one of the change button 151 and the delete button 152 may be displayed. The change button 151 is a button for changing the first attribute value included in the product name or the product description to another attribute value. Thereby, the exhibitor can specify an attribute value more appropriate than the first attribute value specified by the attribute value specifying unit 143 as a new first attribute value. For example, when the change button 151 is pressed, the user terminal 2 displays a candidate for the first attribute value. The candidate for the first attribute value is, for example, an attribute value having a relatively high feature value similarity or an attribute value having a similarity greater than or equal to a predetermined value. For example, “white red”, “red”, “white”, and the like are displayed as candidates for the first attribute value of the color. The delete button 152 is a button for deleting the corresponding first attribute value from the product name or the product description. The exhibitor can delete the unnecessary first attribute value. For example, the exhibitor can delete the current first attribute value in order to input an attribute value not included in the candidate as a new first attribute value. The change button 151 and the delete button 152 may not be displayed. Even in this case, the exhibitor can change and delete the first attribute value by editing the product description in the product description input area 120. Further, the exhibitor can freely input additional characters in the product description input area 120.

  The system control unit 14 may function so as to reflect the result of the review of the first attribute value by the seller in the specification of the first attribute value from the product information by the attribute value specifying unit 143. The review of the first attribute value includes consideration of whether to change the first attribute value and consideration of whether to delete the first attribute value. The first attribute value finally registered as product information through the specification by the attribute value specifying unit 143 and the review by the exhibitor is considered to be the optimal first attribute value corresponding to the target product image. Therefore, the system control unit 14 performs machine learning with the product image as an input and the final first attribute value as an output. Based on the learning result, the attribute value specifying unit 143 specifies the first attribute value from the product image. Thereby, the specific accuracy of the first attribute value can be increased.

  When the second attribute exists, second attribute information 160 is further displayed on the product information input screen. The second attribute information 160 includes at least a second attribute name. The second attribute information 160 may be a message that prompts the user to input a second attribute value, such as “Would you like to enter a coordination example?”. Thereby, an exhibitor can recognize the 2nd attribute which may need to input a 2nd attribute value corresponding to the category of goods. However, the exhibitor may or may not input the second attribute. In the example shown in FIG. 6, second attribute information 160-1 and 160-2 are displayed. The second attribute information 160-1 is a message that prompts input of a size. The second attribute information 160-2 is a message that prompts input of a coordinate example. The second attribute value input area 170 may be displayed according to each second attribute information 160. The second attribute value input area 170 is an area for inputting a second attribute value. In the example shown in FIG. 6, second attribute value input areas 170-1 and 170-2 are displayed. The second attribute value input area 170-1 is an area for inputting a size. The second attribute value input area 170-2 is an area for inputting a coordination example. The second attribute value input area 170 may not be displayed. Even in this case, the exhibitor can input the second attribute value in the product name input area 110 and the product description input area 120.

  The presentation control unit 144 may cause the user terminal 2 to present the second attribute before displaying the product information input screen or without displaying the product information input screen. At this time, the presentation control unit 144 may cause the first attribute value to be presented together with the second attribute so that the first attribute value can be changed by the exhibitor. The exhibitor inputs the second attribute value according to the presented second attribute. When the first attribute value is presented, the exhibitor may or may not change the first attribute value. The presentation control unit 144 may display a product information input screen in which each of the first attribute value and the second attribute value is input in advance in the product name input area 110 or the product description input area 120. When the first attribute value is changed, the changed first attribute value is input in advance in the product name input area 110 or the product description input area 120. When the product information input screen is not displayed, product information including the identified first attribute value and the input second attribute value as it is is stored in the product DB 12b by the product information registration unit 145.

  The presentation control unit 144 includes, in the product information of the products that have been exhibited so far, the first sale establishment rate of the product corresponding to the product information including the attribute value corresponding to the second attribute, and the attribute corresponding to the second attribute You may control presentation of a 2nd attribute based on the difference with the 2nd sale completion rate of the goods corresponding to the goods information which does not contain a value.

  An example of a method for calculating the sale completion rate is shown. When product information is stored in the product DB 12b, the product information registration unit 145 identifies an attribute name corresponding to an attribute value included in the product name and the product description, associates the product with the product information, and identifies the identified attribute name. You may memorize | store in goods DB12b. The presentation control unit 144 obtains, for each second attribute, product information including an attribute value corresponding to the second attribute among the product information corresponding to the category ID acquired by the image / category acquisition unit 141 from the product DB 12b. get. The presentation control unit 144 counts the number of pieces of product information in which the exhibition state is “sales completed” and the number of pieces of product information in which the exhibition state is “being exhibited” or “exhibition stopped” in the acquired product information. . The presentation control unit 144 divides the number of product information whose listing status is “selling completed” by the number of product information whose listing status is “currently exhibiting” or “selling stopped”, thereby obtaining the first sales rate. calculate. In addition, the presentation control unit 144 acquires product information that does not include the attribute value corresponding to the second attribute from the product DB 12b among the product information corresponding to the category ID acquired by the image / category acquisition unit 141. Thereafter, the presentation control unit 144 calculates the second sale completion rate by the same method as that for the first sale establishment rate.

  The example of the control method of presentation of the 2nd attribute is shown. When the first sale completion rate is higher than the second sale establishment rate by a predetermined value or more, the presentation control unit 144 displays the second attribute information 160 indicating that the sale establishment rate increases when the second attribute value is input. May be displayed. In the example shown in FIG. 6, it is assumed that the first sale completion rate is higher than the second sale establishment rate by a predetermined value or more. In this case, as the second attribute information 160-1, for example, a message such as “When a size is input, sales are improved.” May be displayed. As for the coordinate example, it is assumed that the first sale completion rate is not higher than the second sale establishment rate by a predetermined value or more. In this case, as the second attribute information 160-2, for example, a message such as “Would you like to input a coordination example?” May be displayed.

  The presentation control unit 144 may cause the user terminal 2 to present only an attribute of the second attribute in which the first sale completion rate is higher than the second sale establishment rate by a predetermined value or more. In the example shown in FIG. 6, second attribute information 160-1 corresponding to a size in which the first sale completion rate is higher than the second sale establishment rate by a predetermined value or more is displayed. In this case, the second attribute information 160-1 may be either “Would you like to enter a size?” Or “If you enter a size, sales will improve.” The second attribute information 160-2 (and the second attribute value input area 170-2) corresponding to the coordinate example is not displayed.

  Regardless of which method is used, the user can recognize the second attribute that is likely to increase the rate of sale completion when the second attribute value is input.

  The presentation control unit 144 may cause the user terminal 2 to display the reference information of the input price. For example, the presentation control unit 144 identifies, from the product DB 12b, product information whose exhibition state is “buying and selling completed” among the product information corresponding to the category ID acquired by the image / category acquisition unit 141. The presentation control unit 144 calculates an average value of prices included in the specified product information. The presentation control unit 144 may display an average price value as reference information on the product information input screen. For example, information such as “the average price of a tunic that has been sold and sold is 4,000 yen” is displayed. Alternatively, the presentation control unit 144 may display the product information input screen on the user terminal 2 in a state where the calculated average price is input in the price input area 130 in advance.

  The merchandise information registration unit 145 stores the merchandise information including the first attribute value specified by the attribute value specifying unit 143 and the second attribute value input by the seller in response to the presentation of the second attribute in the merchandise DB 12d. Let For example, the merchandise information registration unit 145 is input to the merchandise name input area 110, the merchandise description input area 120, and the second attribute value input area 170 on the merchandise information input screen in response to pressing of the exhibition button 140, respectively. The product name, the product description, and the second attribute value are received from the user terminal 2. The product information registration unit 145 adds the received second attribute value to the product name or product description. The product information registration unit 145 generates product information including a product name and a product description. Since the first attribute value is input in advance in the product name input area 110 or the product description input area 120, unless the seller changes or deletes the first attribute, the product information has an attribute value specification. The first attribute value specified by the unit 143 is included. Even if the product information input screen does not include the second attribute value input area 170, the seller can view the second attribute information 160 in the product name input area 110 or the product description input area 120. There is a probability of inputting attribute values. Accordingly, the product information has a probability of including the second attribute value.

  The product information registration unit 145 may include the second attribute value in the product name and include the first attribute value in the product description. This is because the priority for displaying the product image and the product name is higher than the priority for displaying the product description. As screens for displaying information about products in the market application, there are a product detail screen and a product list screen. On the product detail screen, information related to the product selected by the user from the product list screen is displayed. All information included in the product information is basically displayed on the product detail screen. A list of products searched based on the user's request is displayed on the product list screen. For example, the product image, product name, price, etc. of each product are displayed. On the product list screen, all or part of the product description is not displayed. On the product list screen, information on as many products as possible is displayed, so the types of information displayed are limited. The first attribute value specified from the product image is an attribute value that is likely to be recognized by the user by looking at the product image. For example, the shape, color, pattern, etc. can be recognized from the product image. Therefore, the necessity for displaying the first attribute value on the product list screen is low. Therefore, by including the second attribute value in the product name, the user can recognize more attribute values. The number of characters in the character string of the second attribute value may be long. For example, the number of characters in the coordinate example may be long. The merchandise information registration unit 145 includes the second attribute value whose number of characters is a predetermined value or more in the merchandise description without including it in the merchandise name, or extracts the keyword from the second attribute value and uses only the keyword as the merchandise name. May be included. In order to include the first attribute value in the product description, the product information registration unit 145 may be in a state where the first attribute value has already been input in the product description input area 120 as shown in FIG. Alternatively, the product information registration unit 145 may display the first attribute value at a place other than the input area on the product information input screen. Corresponding to the displayed first attribute, for example, information such as “these attribute values are added to the product description” may be displayed. The product information registration unit 145 may add the first attribute value to the product description received from the user terminal 2.

  Fig.7 (a) is a figure which shows an example of the goods detail screen of tunic P1. As shown in FIG. 7A, the product detail screen includes a category 210, a product name 220, a product image 230, a product description 240, a price 250, a purchase button 260, and the like. It is assumed that the seller inputs “Shipping included! Cute tunic” as the product name on the product information input screen. In addition, the exhibitor inputs the second attribute value “M size” corresponding to the size and the second attribute value “Match hoodie and tight pants for this tunic.” To do. In this case, for example, “Shipping included! Coordination of cute tunic M size parka and tight pants” is displayed as the product name 220. The product name 220 includes first attribute values “tunic”, “red”, “border”, and “knit”. Since the number of characters in the coordination example is long, the keyword extracted from the coordination example and “coordination between parker and tight pants”, which is a part of the first attribute name, are included in the product name 220.

  FIG. 7B is a diagram illustrating an example of a product list screen. As shown in FIG. 7A, the product list screen displays simple information 300 for each product. The simple information 300 includes a product image 310, a product name 320, and a price 330.

  A priority order may be set in advance for each attribute. If at least one second attribute value among the input second attribute values cannot be included in the product name due to the limitation on the maximum number of characters in the product name, the product information registration unit 145 determines that the number of characters in the product name is the maximum number of characters. The second attribute value having a high priority may be preferentially included in the product name so as not to exceed the value. The product information registration unit 145 includes the second attribute value that is not included in the product name in the product description. When the second attribute value is included in the product description, the product information registration unit 145 may include the second attribute value at the head of the product description. In this case, the second attribute value included in the product description can be displayed in a mode in which the top part of the product description is displayed on the product list screen.

  The product information registration unit 145 may include the first attribute value in the product name when the second attribute does not exist or when any second attribute value is not input. Further, the product information registration unit 145 may have the number of characters of the product name less than the maximum number of characters even if all the second attribute values are included in the product name. In this case, the product information registration unit 145 may include all the second attribute values in the product name and also include the first attribute value in the product name so that the number of characters of the product name does not exceed the maximum number of characters. That is, the second attribute value is included in the product name preferentially over the first attribute value. When there are a plurality of first attribute values, the merchandise information registration unit 145 may preferentially include the first attribute value having a higher priority set in the merchandise name from among the first attribute values. Good. Alternatively, the product information registration unit 145 may preferentially include the first attribute value having a high similarity calculated by the attribute value specifying unit 143 in the product name when specifying the first attribute value. That is, the first attribute value having a high specific accuracy is preferentially included in the product name. The product information registration unit 145 may include the first attribute value changed by the exhibitor in the product name and include the first attribute value not changed by the exhibitor in the product description. For the first attribute corresponding to the first attribute value changed by the seller, the attribute value specifying unit 143 specifies the erroneous first attribute value from the product image, and the seller is correct with the specified first attribute value. There is a probability of changing to the first attribute value. By including the changed first attribute value in the product name, the correct first attribute value is displayed together with the product image on the product list screen. Thereby, the user who views the product list screen can recognize the correct first attribute value from the product name without recognizing the erroneous first attribute value from the product image.

  The product information registration unit 145 may include the first attribute value in the product name and include the second attribute value in the product description. In this case, the product information registration unit 145 may be in a state where the first attribute value has already been input to the product name input area 110. Alternatively, an attribute that includes an attribute value in the product name and an attribute that includes an attribute value in the product description may be determined in advance.

  An element that is not necessarily possessed by all the products belonging to a predetermined category may be attached to the product represented by the product image. When such an element is recognized as the first attribute value from the product image, the attribute value specifying unit 143 may specify an attribute value corresponding to a predetermined attribute of the element from the product image. The predetermined element may be a picture and the predetermined attribute may be a picture motif. For example, when specifying the attribute value of the pattern from the product image, the attribute value specifying unit 143 determines whether or not any picture is attached to the product from the product image. The attribute value specifying unit 143 extracts the feature amount of the picture, and compares the extracted feature amount with the feature amount corresponding to the attribute name “picture motif” stored in the attribute value DB 12c, thereby obtaining the attribute value. Is identified. The merchandise information registration unit 145 may include the extracted attribute value as the first attribute in the merchandise information. The presentation control unit 144 may cause the user terminal 2 to present the predetermined attribute as the second attribute when the attribute value corresponding to the predetermined attribute cannot be specified. For example, if it is recognized that some kind of picture is attached to the product, but the picture motif cannot be specified, the presentation control unit 144 may cause the attribute name “picture motif” to be presented. . For the elements that are not necessarily possessed by all products, the exhibitor can arbitrarily input information on the elements in the product name input area 110 or the product description input area 120.

  FIG. 8 is a diagram illustrating an example of an outline of processing performed by the system control unit 14. As shown in FIG. 8, the product image represents a T-shirt P2. A picture D is printed on the T-shirt P2. The category is “T-shirts”. From the product image, the attribute value specifying unit 143 uses “T-shirt” corresponding to the shape, “white” corresponding to the color, “plain, picture” corresponding to the pattern, and “cotton” corresponding to the material as the first attribute value. Was identified. However, although the attribute value specifying unit 143 recognizes that the portion of the T-shirt P2 of the product image includes a certain picture, the attribute value specifying unit 143 cannot specify the motif of the picture. The attribute list of the T-shirt includes “shape”, “color”, “pattern”, “material”, “size”, and “coordinate example”. In this case, the second attributes are “size”, “coordinate example”, and “picture motif”.

  FIG. 9 is a diagram illustrating an example of a product information input screen. 9 differs from FIG. 6 in that the first attribute values “T-shirt”, “white”, “plain”, and “cotton” are input in the product description input area 120, and the second attribute information. 160-3 and the second attribute value input area 170-3 are added. The second attribute information 160-3 is a message such as “Would you like to input a T-shirt picture motif?”, For example. The second attribute value input area 170-3 is an input area for inputting a picture motif.

  When selling a plurality of products as one set of products, the seller has a probability of uploading a product image including the plurality of products. Therefore, the attribute value specifying unit 143 may recognize a plurality of products from one product image. In this case, the attribute value specifying unit 143 may specify the first attribute value for each of a plurality of products from the product image. In this case, the attribute list acquisition unit 142 acquires the attribute list without using the category ID acquired by the image / category acquisition unit 141 by the category selection by the exhibitor. This is because a person is likely to select “Other” as the category, and the category of the product itself becomes “Other”. The attribute list acquisition unit 142 may acquire an attribute list corresponding to the category ID of the category to which each of the plurality of products belongs from the category DB 12b. The presentation control unit 144 may cause the user terminal 2 to present the second attribute for each of the plurality of products. Thereby, about the set containing a some goods, an appropriate 2nd attribute can be shown corresponding to each goods.

  FIG. 10 is a diagram illustrating an example of an outline of processing performed by the system control unit 14. As shown in FIG. 10, the product image represents a T-shirt P3 and a skirt P4. The exhibitor selected “Others” in “Ladies Fashion” as the category. The attribute value specifying unit 143 specifies “T-shirt” and “knee length skirt” as the first attribute value corresponding to the shape from the product image. The attribute value specifying unit 143 further specifies “red gray” corresponding to the color and “border” corresponding to the pattern as the first attribute value of the T-shirt P3. The attribute value specifying unit 143 further specifies “navy” corresponding to the color and “plain color” corresponding to the pattern as the first attribute value of the skirt P4. The attribute list acquisition unit 142 acquires an attribute list of the T-shirt and an attribute list of the knee length skirt. The attribute list of the T-shirt includes “shape”, “color”, “pattern”, “size”, and “length”. Assume that the knee length skirt attribute list includes “shape”, “color”, “pattern”, and “size”. Accordingly, the second attribute for the T-shirt P3 is size and length, and the second attribute for the skirt P4 is size.

  FIG. 11 is a diagram illustrating an example of a product information input screen. In FIG. 11, the first attribute of each of the T-shirt P <b> 3 and the skirt P <b> 4 is input in the product description input area 120. In addition, on the product information input screen, second attribute information 160-4 to 6 and second attribute value input areas 170-4 to 7 are displayed. The second attribute information 160-4 is information that prompts the user to input the size of the T-shirt P3. The second attribute information 160-5 is information that prompts the user to input the length of the T-shirt P3. The second attribute information 160-6 is information that prompts the user to input the size of the skirt P4. The second attribute value input areas 170-4 to 170-6 correspond to inputs of the size of the T-shirt P3, the length, and the size of the skirt P4, respectively.

[4. Operation of the market system]
Next, operation | movement of the market system S is demonstrated using FIG.12 and FIG.13.

  FIG.12 and FIG.13 is a flowchart which shows an example of the exhibition process of the system control part 14 of the market server 1 which concerns on this embodiment. 12 and 13 show an example of processing when the first attribute value is included in the product description and the second attribute value is included in the product name. The system control unit 14 executes the processes shown in these drawings according to various codes included in the server program.

  The exhibitor activates the market application by the user terminal 2 and then selects an exhibit from the menu. Then, the user terminal 2 displays a screen for uploading a product image. The exhibitor takes a product image using the camera function of the user terminal 2 or selects a product image from the images stored in the user terminal 2. The user terminal 2 transmits the product image to the market server 1. When the market server 1 receives the product image, the system control unit 14 executes an exhibition process.

  As shown in FIG. 12, the image / category acquisition unit 141 acquires a product image received from the user terminal 2 via the communication unit 11 (step S11). Next, the attribute value specifying unit 143 specifies the first attribute value from the product image (step S12). For example, the attribute value specifying unit 143 extracts the feature amount of the attribute from the product image for each attribute. The attribute value specifying unit 143 calculates the similarity between each feature quantity corresponding to the attribute and the extracted feature quantity in the attribute value DB 12c. Of the attribute values corresponding to the attribute, the attribute value specifying unit 143 determines, for example, the attribute value having the highest similarity and having the highest similarity as the first attribute value of the attribute. The attribute value specifying unit 143 may specify the first attribute value corresponding to the shape first from the product image. When the shape of a plurality of products is specified from the product image, the attribute value specifying unit 143 specifies the first attribute value from the image portion of the target product among the product images for each product.

  Next, the image / category acquisition unit 141 determines a category candidate for the product to be exhibited (step S13). For example, the image / category acquisition unit 141 obtains, for each attribute, an attribute value whose feature value similarity is equal to or greater than a predetermined value or a predetermined number of attribute values having a relatively high similarity value from the attribute value corresponding to the attribute. Extract. The image / category acquisition unit 141 identifies, for each attribute value extracted for all attributes, a category name that matches the attribute value from the category DB 12b. The image / category acquisition unit 141 acquires a category ID corresponding to the specified category name as a category candidate category ID from the category DB 12b.

  Next, the image / category acquisition unit 141 displays a category selection screen on the user terminal 2 (step S14). On the category selection screen, the exhibitor can select the category of the product to be exhibited from the candidates determined in step S13. When there is no appropriate category among candidates, the exhibitor can select a category of the product to be exhibited from all categories. When the shapes of a plurality of products are specified in step S12, the image / category acquisition unit 141 causes the user terminal 2 to display a category selection screen for selecting a category from all categories. When the exhibitor selects a category, the user terminal 2 transmits the category ID of the selected category to the market server 1. The image / category acquisition unit 141 acquires the category ID received from the user terminal 2 via the communication unit 11 (step S15). At this time, the attribute value specifying unit 143 may change the first attribute value corresponding to the shape to an attribute value that matches the category name corresponding to the acquired category ID.

  Next, the attribute list acquisition unit 142 acquires an attribute list from the category DB 12b (step S16). When the shape of the plurality of products is not specified in step S12, the attribute value specifying unit 143 acquires an attribute list corresponding to the category ID acquired in step S15. When the shape of a plurality of products is specified, the attribute list acquisition unit 142 specifies a category name that matches the first attribute value of the specified shape for each of the plurality of products from the category DB 12b. The attribute list acquisition unit 142 acquires an attribute list corresponding to the specified category name from the category DB 12b.

  Next, the presentation control unit 144 deletes the attribute name corresponding to the first attribute value specified in Step S12 from the attribute list (Step S17). For example, the presentation control unit 144 acquires the attribute name corresponding to the first attribute value from the attribute value DB 12c. When the attribute list includes the same attribute name as the acquired attribute name, the presentation control unit 144 deletes the attribute name. When the shape of a plurality of goods is specified at Step S12, presentation control part 144 deletes the attribute name corresponding to the 1st attribute value from an attribute list for every goods.

  Next, the presentation control unit 144 determines whether or not a predetermined element is attached to the product in the product image based on the first attribute value specified in Step S12 (Step S18). At this time, if the presentation control unit 144 determines that the predetermined element is not attached (step S18: NO), the process proceeds to step S31. On the other hand, if the presentation control unit 144 determines that a predetermined element is attached (step S18: YES), the presentation control unit 144 advances the process to step S19. In step S19, the presentation control unit 144 determines whether or not an attribute value corresponding to a predetermined attribute of a predetermined element has been specified based on the identification result of the first attribute value in step S12. At this time, when it is determined that the attribute value corresponding to the predetermined attribute has not been specified (step S19: NO), the presentation control unit 144 advances the process to step S31. On the other hand, when it is determined that the attribute value corresponding to the predetermined attribute has been specified (step S19: YES), the presentation control unit 144 advances the process to step S20. In step S20, the presentation control unit 144 adds the attribute name of the predetermined attribute to the attribute list, and advances the process to step S31. When the shape of a plurality of goods is specified at Step S12, presentation control part 144 performs Steps S18-20 for every goods.

  In step S31, the presentation control unit 144, as shown in FIG. 13, for each attribute name included in the attribute list, the first sale completion rate of the product whose product information includes the attribute value corresponding to the attribute name, and A second sale establishment rate is calculated for a product that does not include product information for the attribute value corresponding to the attribute name. Next, the presentation control unit 144 subtracts the second sale establishment rate from the first sale establishment rate for each attribute name, and calculates the difference between the sale establishment rates. Next, the presentation control unit 144 deletes, from the attribute list, the attribute name having a difference in the sale completion rate that is less than the predetermined value among the attributes included in the attribute list (step S32).

  Next, the presentation control unit 144 generates a product description including the first attribute value specified in step S12 (step S33). Next, the presentation control unit 144 displays a product information input screen on the user terminal 2 (step S34). For example, the presentation control unit 144 transmits a product information input screen display command including an attribute list and a product description to the user terminal 2. Upon receiving the product information input screen display command, the user terminal 2 displays a product information input screen. In addition, the user terminal 2 acquires an attribute list from the product information input screen display command. For each attribute name included in the attribute list, the user terminal 2 displays the second attribute information 160 and the second attribute value input area 170 corresponding to the attribute name. In addition, the user terminal 2 displays the product description included in the product information input screen display command in the product description input area 120.

  The exhibitor inputs a product name in the product name input area 110. In addition, the exhibitor adds a description to the product description input area 120 or edits the product description. The exhibitor inputs the second attribute value in the second attribute information 160. The exhibitor inputs a price in the price input area 130. When the exhibitor presses the display button 140, the user terminal 2 transmits the input product name, product description, second attribute value, price, and the like to the market server 1. The product information registration unit 145 acquires the product name, product description, second attribute value, price, and the like received from the user terminal 2 via the communication unit 11 (step S35). Next, the product information registration unit 145 adds the second attribute value to the product name (step S36). Next, the merchandise information registration unit 145 generates merchandise information including a merchandise image, a merchandise name, a merchandise description, a price, the category ID acquired in step S15, the user ID of the exhibitor, and an exhibition status indicating “being exhibited”. To do. And the merchandise information registration part 145 memorize | stores merchandise information in merchandise DB12d (step S37), and complete | finishes an exhibition process.

  As described above, according to the present embodiment, the system control unit 14 acquires a product image and a category ID. Further, the system control unit 14 acquires an attribute list corresponding to the acquired category ID from the category DB 12b. Further, the system control unit 14 specifies the first attribute value of the product from the product image. Further, the system control unit 14 presents a second attribute that does not correspond to the first attribute value among the attributes included in the acquired attribute list. Further, the system control unit 14 stores product information including the first attribute value and the second attribute value input by the exhibitor in response to the presentation of the second attribute in the product DB 12d. Therefore, it is possible to register a large amount of information regarding the product while reducing the time and effort required by the seller.

  In addition, the system control unit 14 stores product information including a product name including the second attribute value input by the seller in response to the presentation of the second attribute and a product description including the first attribute value in the product DB 12d. It may be memorized. In this case, on the screen displaying the list of products, the buyer can recognize more attribute values with less information. Specifically, the buyer can recognize the first attribute value from the product image and can recognize the second attribute value from the product name.

  In addition, the system control unit 14 includes, in the product information stored in the product DB 12d, the first sale establishment rate of the product corresponding to the product information including the attribute value corresponding to the second attribute, and the attribute corresponding to the second attribute. You may control presentation of a 2nd attribute based on the difference with the 2nd sale completion rate of the goods corresponding to the goods information which does not contain a value. In this case, by controlling the presentation of the second attribute based on the difference in the sale completion rate, the exhibitor may recognize the second attribute that increases the sale establishment rate by inputting the second attribute value among the second attributes. it can.

  Further, when a predetermined element included in the product is recognized from the product image, the system control unit 14 may specify an attribute value corresponding to a predetermined attribute of the predetermined element from the product image. Further, when the system control unit 14 cannot identify the attribute value corresponding to the predetermined attribute, the predetermined attribute may be presented.
