<First embodiment>
<Overview of First Embodiment>
In the first embodiment, when a purchase user requests browsing of a product page, a server generates a product description based on the product information and information on the purchase user in a system for trading products between users performed via a network. This is an embodiment of a description generating method for transmitting a product page including the product description to the terminal of the purchase user.

  In the present embodiment, the “selling user” is a user who sells a product, and the “purchasing user” is a user who purchases a product. Further, in this embodiment, unless otherwise described, the user A will be described as an exhibiting user, and the users B and C will be described as purchasing users. Note that the same user can be both the exhibiting user and the purchasing user.

  First, the outline of the description generating method according to the first embodiment will be described with reference to FIG. As shown in FIG. 3, in the first embodiment, a communication system 1 for buying and selling goods by the server 110 and the terminal 120 is constructed. In the present embodiment, the terminal used by user A is terminal 120A, and the terminals used by user B and user C are terminal 120B and terminal 120C, respectively. When selling a product, the user A transmits the product information of the product to be sold to the server 110A using the terminal 120A. In the present embodiment, a case where the user A submits a book will be described as an example. In order to assist the user A in inputting product information, a screen for inputting product information is displayed on the screen of the terminal 120A. The user A inputs product information according to the input screen, and transmits the product information to the server 110A. As shown in FIG. 3, in the present embodiment, the user A inputs the rarity of the book “rare” as the product information and inputs the product image. The server 110A stores the product information received from the user A.

  On the other hand, when purchasing a product, the user B and the user C can browse the product page on which the product information is posted. When the user B and the user C make a display request of the product page to the server 110A, the server 110A generates a product description based on the product information and the information on the purchasing users (users B and C). After that, the server 110A transmits the product page including the generated product description to the terminal 120B and the terminal C, respectively. At this time, since the product description is generated based on information about the purchase user such as the product page browsed by the purchase user in the past and the age of the purchase user, a product description different for each purchase user is displayed. For example, as shown in FIG. 3, the product description displayed on the terminal 120B has a polite style such as "It is a very rare book", whereas the product description displayed on the terminal 120C. Is a different text with a rough style, such as "It's a very rare book!"

  It should be noted that the products traded using the communication system 1 are not necessarily limited to articles, and services such as agency of cleaning work can also be traded.

<Effect of First Embodiment>
According to the description generating method according to the first embodiment, the server 110A generates the product description based on not only the product information but also the information on the purchasing user. The effect that a high product description can be provided can be obtained. Further, even if the selling user does not input the product information in detail, a product description with a high appealing power matching the attributes and preferences of the purchasing user is provided, so that the burden of the selling user on the selling operation is reduced. Furthermore, the processing load and communication load on the server are reduced as compared with the case where the exhibiting user generates a large number of product pages according to the attributes and preferences of the purchasing user, and a smooth transaction is realized.

<Functional Configuration of First Embodiment>
The functional configuration of the server 110 and / or the terminal 120 will be described with reference to FIG. The functional unit disclosed in FIG. 4 is realized by cooperation of a processor 201, a memory 202, a storage 203, an input / output I / F 204, and a communication I / F 205 included in the information processing apparatus 200. FIG. 4 is a block diagram showing a functional configuration of a communication system 1 for performing a sales transaction of a product between an exhibiting user and a purchasing user. The communication system 1 includes servers 110A and 110B and terminals 120A, 120B and 120C. including.

(1) Functional Configuration of Server The server 110A includes an input / output I / F 311, a communication I / F 312, a control unit 313, and a storage unit 314. The server 110A includes a communication I / F 312, a control unit 313, and a storage unit 314. The control unit 313 includes a generation unit 315, an acquisition unit 316, and an update unit 317. The storage unit 314 stores product information 410, action history information 420, and user attribute information 430 in addition to the program 400. The configuration of the server 110B is the same as that of the server 110A, and a description thereof will be omitted.

  The communication I / F 312 transmits and receives information to and from the terminal 120 and another server 110B via the network 130. For example, the product information of the exhibited product is received from the terminal 120A, and the product page is transmitted to the terminals 120B and 120C. Note that the communication I / F 312 corresponds to the communication I / F 205 in FIG. 2 described above.

  The generation unit 315 generates a product description based on the product information 410 and information on the purchasing user. The generated product description forms a product page together with other product information.

  Here, the “product information” is various information related to the product, and includes, for example, a category of the product, a size of the product, a rarity of the product, an identifier attached to each product for sale, and the like. The “information on the purchase user” is user information on the purchase user, and includes information on the past behavior of the purchase user (action history information) and attribute information of the purchase user. For example, the action history information includes the number of browsing times and browsing times of the product pages browsed by the purchasing user in the past, and the attribute information includes gender, age, and location information of the purchasing user. The “product page” is a page for introducing a product, and includes a product description, a product image, and the like. The product page is displayed on the terminal (120B, 120C) of the purchasing user as shown in FIG.

  The acquisition unit 316 acquires from the storage unit 314 information used when the generation unit 315 generates the product description. For example, when the generation unit generates the product description sent to the user B, the storage unit 314 acquires the product information of the product for which the description is generated and the information on the user B.

  The updating unit 317 updates the information stored in the storage unit 314. For example, when the server 110A receives new product information from the terminal 120A, the information is additionally updated based on the received product information. What the updating unit 317 performs is not limited to adding information. For example, when the server 110A receives an instruction to reduce product information from the user, the server 110A reduces the product information stored in the storage unit 314 based on the received instruction.

  Further, the update unit 317 may automatically update information as well as when receiving an instruction from the user. For example, when the generation unit 315 estimates other product information such as a category, a model number, and a material of a product based on the product image stored in the product information 410 of the storage unit 314, the updating unit 317 performs processing based on the estimated information. The product information may be updated.

  The storage unit 314 stores product information 410, action history information 420, and user attribute information 430 in addition to the program 400. The product information 410, action history information 420, and user attribute information 430 will be described with reference to FIGS.

  First, the product information 410 will be described. Part of the product information 410 is managed in the product information table 410A. FIG. 5 is a diagram illustrating an example of the product information table 410A. The merchandise information table 410A has columns of "exhibitor name", "exhibition identifier", "category", "rareness", "image", and "version information", and information corresponding to each column is managed. ing. The information included in the product information table 410A is not limited to these, and may include arbitrary product information.

  The column of “seller name” manages the names of the users who have sold the products. Using the name of the user as an identifier, it is possible to identify which user exhibited each product. In the present embodiment, it can be seen that each of the user A and the user B has exhibited a product.

  In the column of “exhibition identifier”, an identifier for identifying a commodity for sale is managed. Even if the products are of the same category or model number, a different exhibition identification is assigned to each product, and it is possible to identify the exhibited product by the exhibition identifier. In this example, the selling identifier is “123” for the selling of the user A and “124” for the selling of the user B.

  The column of “category” manages the category of the exhibited product. Not only the category of “books” shown in FIG. 5 but also a category of a higher concept and a category of a lower concept may be managed. In the case of this example, the category of the merchandise with the exhibition identifiers “123” and “124” is “book”.

  The column of “rareness” manages information on the rarity of exhibited products. The determination of the rarity of the product may be performed based on the user's subjectiveness, or may be performed based on a criterion determined on the management side that manages the server 110A. In the case of this example, the merchandise with the exhibition identifiers "123" and "124" both have a rareness of "rare".

  In the column of "image", information on the image of the exhibited product is managed. The product information table 410A illustrated in FIG. 5 manages information on which side of the product the product image stored in the storage unit 314 is. In this example, both the user A and the user B input three types of images of “front, side, and back”. The product image may be stored in the storage unit 314 separately from the product information table 410A.

  In the column of “version information”, information on the version of the book that has been exhibited is managed. The product information table 410A shown in FIG. 5 does not include the version information of the book exhibited by the user A. Therefore, it is understood that the user A has not input the book version information. On the other hand, the user B has input “first edition” for the edition information.

  Next, the action history information 420 will be described. Part of the action history information 420 is managed by the page browsing information table 420A. The page browsing information table 420A manages information on product pages browsed by the user in the past. FIG. 6 is a diagram showing an example of the page browsing information table 420A, and the table shown in FIG. 6 manages information on a product page browsed by the user B in the past.

  The page browsing information table 420A includes columns of “page identifier”, “language”, “style”, “number of times”, “total browsing time”, and “evaluation”, and information corresponding to each column is managed. I have. Note that information included in the page browsing information table 420A is not limited to these.

  The “page identifier” column manages identifiers for identifying product pages. The page identifier shown in FIG. 6 is a number assigned to each product page. The product page that the user browsed in the past can be identified by the page identifier.

  The “language” column manages information on the language used in the product page. Here, the language used for the product page may be the language of the product description included in the product page. In the case of this example, it is shown that "Japanese" is used in the pages with the page identifiers "300" and "302", and "English" is used in the page with the page identifier "301". When a plurality of languages are used, the column of “language” may include information of a plurality of languages.

  In the column of “style”, information on the style of the product description sentence included in the product page is managed. The information on the style includes all information on the sentence style, the vocabulary included in the sentence, the sentence expression, and the like. In the present embodiment, information on the style is stored as to whether the product description is a “polite” style or a “rough” style. If the language of the item description is Japanese, "attentive" is stored when the sentence ends in a so-called "masu-tona", otherwise "rough" is stored. If the language of the product description is English, the determination is made based on the words included in the text. Specifically, it is determined whether a word giving a polite impression such as “Thank you” or a word giving a rough impression such as “Thanks” is more present in the sentence. Note that the information on the style is not limited to whether the style is “attentive” or “rough”. For example, the words used in the first person, the average number of characters per sentence, and the like may be managed as information about the style.

  The column of “number of times” manages a total value of the number of times the user has viewed the product page in the past. The number of times managed may be the total number of times of browsing during a predetermined number of days. In the case of this example, the user B browsed the page with the page identifier “300” “8” times, the page with the page identifier “301” “1” times, and viewed the page with the page identifier “302” “3” times. It is shown.

  The column of “total browsing time” manages the total time of the user browsing the product page in the past. In addition, the total time managed may be the total time browsed during a predetermined number of days. In the case of this example, it is indicated that the user B browsed the page with the page identifier “300” for 30 minutes, the page with the page identifier “301” for 3 minutes, and the page with the page identifier “302” for 14 minutes.

  The column of “evaluation” manages the evaluation results performed by the user on the product page. The evaluation of the product page by the user may be performed by the evaluating user using an arbitrary standard such as appropriateness of the amount of information included in the product page and readability of the product description. In the case of this example, the user B numerically evaluates the page with the page identifier “300” as “5”, the page with the page identifier “301” as “2”, and the page with the page identifier “302” as “4”. It is shown. Also, in the present embodiment, the product page is evaluated by numerical values, but the evaluation may be performed by the user selecting a character such as “like” or a specific design displayed on the product page. . In this case, whether or not the user has selected a character such as “like” or a specific symbol is stored in the page browsing information table 420A.

  FIG. 7 is a diagram illustrating an example of the user attribute information table 430A. Part of the user attribute information is managed by the user attribute information table 430A. The user attribute information table 430A manages attribute information of users who use the communication system 1. In the present embodiment, columns of “user name”, “sex”, “age”, and “location information” exist, and information corresponding to each column is managed. Note that the information included in the user attribute information table 430A is not limited to these.

  The column of “user name” manages the names of the respective users. The name of the user functions as an identifier for identifying the user. In the case of this example, “user A”, “user B”, and “user C” are managed as user names.

  The column of “sex” manages user gender information. In the case of this example, it is shown that “user A” and “user C” are “female” and “user B” is “male”.

  In the “age” column, user age information is managed. In the case of this example, it is indicated that “user A” is “17”, “user B” is “55”, and “user C” is “23”.

  The column of “location information” manages information on the location of the user. The position information may be address information input when the user uses the communication system 1 to buy and sell goods. In the case of this example, it is shown that the location information of “user A” is “Tokyo”, the location information of “user B” is “Osaka”, and the location information of “user C” is “USA”.

(2) Functional Configuration of Terminal Next, returning to FIG. 4, the functional configuration of the terminal 120A will be described. The terminal 120A has an input / output I / F 321, a communication I / F 322, a control unit 323, and a storage unit 324. The terminal 120B and the terminal 120C have the same configuration as the terminal 120A, and a description thereof will be omitted.

  The input / output I / F 322 receives input of information and outputs information. For example, the input / output I / F 322 receives an input of product information from the user A. Further, when the user A uses the terminal 120A as a purchasing user, a product page is output. The input / output I / F 321 corresponds to the input / output I / F 204 in FIG.

  The communication I / F 322 transmits and receives information to and from the server 110 and the other terminals 120B and 120C via the network 130. For example, it transmits product information and the like to the server 110A. The communication I / F 322 corresponds to the communication I / F 205 in FIG.

  The control unit 323 controls various processes executed by the terminal 120A. For example, when the input / output I / F 322 receives the input of the product information from the exhibiting user, the input / output I / F 322 controls the communication I / F 322 to transmit the product information.

  The storage unit 324 stores the program 500. When the program 500 stored in the storage unit is executed by the processor 201, the user A can access the communication system 1 and receive a service.

<Operation Processing of First Embodiment>
With reference to FIG. 8, the processing of the communication system 1 according to the first embodiment will be described. FIG. 8 shows an example of a processing sequence of the communication system 1 according to the first embodiment. FIG. 8 shows a sequence of a process of generating a product description in a case where the user B requests display of a product page using the terminal 120B after the user A inputs product information using the terminal 120A.

  First, an exhibition request is transmitted from the terminal 120A to the server 110A (S10). The selling request is an indication of the user's intention to sell the product. For example, the selling request can be made by the user selecting a specific icon or the like displayed on the terminal 120A.

  Next, the server 110A generates a product information input screen (S11). The input screen of the product information may be configured by items of information to be input to the user A, information entry columns, and the like, like the screen of the terminal 120A shown in FIG. The generated product information input screen is transmitted to terminal 120A (S12).

  Next, the user A inputs the product information according to the product information input screen received by the terminal 120A (S13), and transmits the product information to the server 110A. The server 110A that has received the product information stores the product information in the storage unit 314 (S14). For example, the product information table 410A shown in FIG. 5 is updated based on the received product information.

  On the other hand, the purchasing user transmits a display request for the product page from the terminal 120B to the server 110A (S15). The request to display the product page may be made, for example, by selecting a product for which the user wants to view the product page from a list of exhibited products displayed on the terminal 120B. Upon receiving the display request, the acquisition unit 316 of the server 110A acquires the product information and the information on the purchase user from the storage unit 314 (S16). For example, the merchandise information of the merchandise for which the display request of the merchandise page has been received is acquired from the merchandise information table 410A shown in FIG. 5, and the information on the user B is obtained from the page browsing information table 420A shown in FIG. 430A.

  The generation unit 315 of the server 110A generates a product description based on the product information acquired by the acquisition unit 316 and the information on the purchasing user, and further generates a product page including the product description (S17). Thereafter, the communication I / F of the server 110A transmits the generated product page to the terminal 120B (S18).

  The product page received by the communication I / F of the terminal 120B is output by the input / output I / F of the terminal 120B (S19). The server 110A updates the behavior history information 420 of the purchasing user (S20). For example, the number of times of browsing of the page browsing information table 420A shown in FIG. 6 is updated.

  Thereafter, when the user B purchases a product (S21), a notification that the product has been purchased by the user B is sent to the terminal 120A via the server 110A (S22).

<Product Information Input Process of First Embodiment>
With reference to FIG. 9, an input process of the product information in the server 110A will be described. FIG. 9 is a flowchart illustrating an example of the input process of the product information according to the first embodiment. Here, a case where the user A sells a product using the terminal 120A will be described as an example.

  First, the communication I / F 312 of the server 110A receives an exhibition request from the terminal 120A (S100). Then, the generation unit 315 of the server 110A generates an input screen for product information, and the communication I / F 312 transmits the input screen to the terminal 120A (S110). On the other hand, the user inputs the product information according to the product information input screen received by the terminal 120A, and transmits the product information to the server 110A. Here, the server 110A may infer other product information based on the product image input by the user A, and display the estimated product information as an input candidate on the product information input screen. For example, when a product image of a book is input, category information and version information of the product may be estimated from the product image and displayed on the product information input screen. At this time, the user A may input the product information by selecting the product information displayed as the input candidate.

  The communication I / F 312 of the server 110A receives the product information from the terminal 120A (S120). If the received product information is insufficient (S130: Yes), the generation unit 315 of the server 110A generates a message prompting the addition of the product information, and the communication I / F 312 transmits the message to the terminal 120A (S140). ). If the received product information is insufficient, it means that some or all of the items listed on the product information input screen have not been entered or that the product information has already been exhibited. And the amount of information is small. For example, in the product information table 410A shown in FIG. 5, "version information" is not input for the product with the exhibition identifier "123" exhibited by the user A. On the other hand, "version information" is input for the product with the exhibition identifier "124" exhibited by the user B. At this time, the generation unit 315 may determine that the product information input by the user A is insufficient, and may generate a message prompting the addition of the product information. At this time, the generated message for adding the product information may be, for example, a message such as “Please input version information” requesting the user to input version information. Further, the generation unit 315 may generate a message including options such as “first edition” and “second edition”.

  If the product information is not insufficient (S130: No), the received product information is stored in the storage unit 314 without transmitting a message prompting the addition of the product information (S150). Specifically, the product information table 410A shown in FIG. 5 is updated based on the received product information. Thus, the input processing of the product information is completed.

  Note that the determination as to whether or not the input product information is insufficient may not be performed after the user A has finished inputting all the product information. For example, in parallel with the input of the product information by the user A, the server 110A may determine whether the product information is insufficient. At this time, information on the amount of the product information input by the user A may be displayed on the terminal 120A in real time using a gauge, color, or the like. By doing so, the user A can input the product information while checking whether the product information is insufficient.

  Further, when the user A is inputting the product information, the content of the product information for which additional input is required may be output to the terminal 120A based on the already input product information or other similar product information. For example, when category information “book” is input, the generation unit 315 may generate a message requesting input of version information and output the message to the terminal 120A. At this time, the generation unit 315 may generate a message including options such as “first edition” and “second edition”.

<Product page generation processing of the first embodiment>
With reference to FIG. 10, a process of generating a product page in the server 110A will be described. FIG. 10 is a flowchart illustrating an example of a product page generation process according to the first embodiment. Here, a case where user B browses a product page using terminal 120B will be described as an example.

  First, the communication I / F 312 of the server 110A receives a display request for a product page from the terminal 120B (S200). If the condition for generating the product description is satisfied (S210: Yes), the generation unit 315 generates a product description based on the product information 410 and information on the purchaser (S220). Here, the condition for generating the product description is a condition for determining whether the generation unit 315 newly generates a product description. For example, the condition may be whether or not the product page has not been browsed by the user B in the past. In the case of a page browsed in the past, the product introduction sentence has already been generated, so the product description need not be generated. The product page including the generated product description is transmitted to the terminal 120B by the communication I / F 312 (S230).

  On the other hand, if the generation condition of the product description is not satisfied (S210: No), for example, if the product page requested to be browsed by the user B in the above example is a product page that has been viewed in the past, a new product The product description generated in the past is transmitted without generating the description (S230). As described above, the product description that is the same as the product description viewed in the past is output to the terminal of the purchasing user, so that the purchasing user can use the same product as the product viewed in the past. It is possible to recognize that there is something uncomfortable. If the product description generated in the past is not stored in the storage unit 314, a product description may be newly generated and transmitted. After transmitting the product page, the storage unit 314 stores action history information such as the number of times the purchase user has viewed the product page and the viewing time. Specifically, the page browsing information table 420A shown in FIG. 6 is updated. Further, the generated product description may be stored as the product information 410.

  Note that the above-described process of generating a product page may be performed not only when a user browses a product page related to a product exhibited by another user but also when a user browses a product page related to a product exhibited by the user.

<< 1st Example >>
The first example of the first embodiment is based on information on the style of a product description included in a product page frequently viewed by a purchase user or a product page viewed for a long time. This is an example of generating.

<< Effect of First Embodiment >>
The product description is generated based on the information on the style of the product description included in the product page where the purchase user views the product page many times or the product page that has long viewing time. For example, a product page that is frequently viewed or a product page that has been viewed for a long time has a high probability of containing a product introduction sentence preferred by the purchaser. Therefore, products based on the style of the product introduction sentence included in these product pages are considered. By generating the description, it is possible to obtain an effect that it is possible to provide a description of the product that more closely matches the taste of the purchaser.

<< Functional Configuration of First Embodiment >>
(1) Functional Configuration of Server The acquisition unit 316 specifies, from the action history information 420 stored in the storage unit 314, a product page that the user B has browsed many times or a product page that has been browsed for a long time. For example, by referring to the page browsing information table 420A, the product page that has been browsed the most or the product page that has been browsed a predetermined number of times or more may be specified as the product page that has been browsed many times. Alternatively, the product page that has been viewed for the longest time or the product page that has been viewed for a predetermined time or more may be specified as the product page that has been viewed for a long time.

  The acquisition unit 316 acquires information (style information) on the style of the product description sentence included in the specified product page. For example, the style information may be acquired by referring to the page browsing information table 420A.

  Further, the obtaining unit 316 obtains the product information of the product for which the display request of the product page has been received from the user B from the product information 410 stored in the storage unit 314. For example, the product information may be acquired by referring to the product information table 410A.

  The generation unit 315 generates a product description based on the product information and style information acquired by the acquisition unit 316.

<< Operation Processing of First Embodiment >>
With reference to FIG. 11, a description process of the product description in the server 110A will be described. FIG. 11 is a flowchart illustrating an example of a product page generation process performed by the server 110A according to the first embodiment. Here, an example will be described in which a product description is newly generated based on a product description included in a product page most frequently viewed by the user B. Note that the product description generation process shown in FIG. 11 is an example of a process performed in the product description generation step (S220) shown in FIG. In the present embodiment, a case will be described as an example where the user B makes a display request for a product page for the product with the exhibition identifier “123” that the user A has exhibited.

  First, when the process is started, the acquisition unit 316 of the server 110A specifies a product page that has been frequently viewed (S221A). For example, referring to the page browsing information table 420A shown in FIG. 6, the product page that has been browsed most frequently by the user B in the past is specified. In this example, the product page with the largest number of browsing times is the product page with the page identifier “300”.

  Next, the acquisition unit 316 acquires the style information of the product description sentence included in the product page (S222A). For example, style information is acquired with reference to the page browsing information table 420A shown in FIG. In this example, the style information of the product description sentence included in the product page with the page identifier “300” is “attentive”.

  After that, the obtaining unit 316 obtains product information on the product for which the display request for the product page has been received (S223A). For example, the product information is acquired with reference to the product information table 410A shown in FIG. In the present example, the product information about the product with the exhibition identifier “123” that the user A has exhibited is acquired.

  The generation unit 315 generates a product description based on the product information and style information acquired by the acquisition unit (S224A). In this example, a product description sentence with a style of “attentive” is generated for the product with the exhibition identifier “123” that the user A has exhibited. This completes the product description generation process.

  Note that the generation unit 315 may generate a product description based on a product description included in a product page to which a purchase user has given an evaluation equal to or higher than a predetermined evaluation. For example, referring to the page browsing information table 420A shown in FIG. 6, the product page with the highest evaluation may be specified, and a product description having the same style as the product description included in the product page may be generated. In the case of this example, the product page with the page identifier “300” has the highest evaluation, and the style of the product description included in the product page is “Polite”. Generate an explanatory note.

<< 2nd Example >>
The second example of the first embodiment is an example in which a product description is generated based on information (language information) on a language used in a product page viewed by a purchase user.

<< Effect of Second Embodiment >>
For example, if the purchasing user browses many product pages written in English, it can be assumed that the purchasing user is a user who uses English, and the English product description may be a sentence that is easy for the purchasing user to understand. Is high. That is, by generating the product description based on the language used in the product page browsed by the purchase user in the past, it is possible to provide a product description with high appeal that is easy for the purchase user to understand. Is obtained.

<< Functional Configuration of Second Embodiment >>
(1) Functional Configuration of Server The acquisition unit 316 acquires language information of a product page browsed by the user B. For example, the language information of the product page that the user B browses most may be acquired. For example, by referring to the page browsing information table 420A shown in FIG.

  The generation unit 315 generates a product description based on the language information acquired by the acquisition unit 316.

<< Operation Process of Second Embodiment >>
With reference to FIG. 12, a description process of the product description in the server 110A will be described. FIG. 12 is a flowchart illustrating an example of a product page generation process performed by the server 110A according to the first embodiment. Here, a case will be described as an example where a product description is generated based on language information of a product page that the user B has browsed most in the past. The product description generation process shown in FIG. 12 is an example of the process performed in the product description generation step (S220) shown in FIG. In the present embodiment, a case will be described as an example where the user B makes a display request for a product page for the product with the exhibition identifier “123” that the user A has exhibited.

  First, when the process is started, the acquisition unit 316 of the server 110A specifies a product page that has been frequently viewed (S221B). For example, referring to the page browsing information table 420A shown in FIG. 6, the product page with the largest number of browsing times is specified. In this example, referring to the page browsing information table 420A, the product page with the largest number of browsing times can be identified as the product page with the page identifier "300" having the browsing frequency of "8" times.

  Next, the acquisition unit 316 acquires information on the language used for the product page (S222B). For example, the language information of the page identifier "300" is acquired with reference to the page browsing information table 420A shown in FIG. In this example, referring to the page browsing information table 420A, it can be seen that the language is "Japanese".

  After that, the acquisition unit 316 acquires the product information about the product for which the display request for the product page has been received (S223B). For example, the product information is acquired with reference to the product information table shown in FIG. In the present example, the product information about the product with the exhibition identifier “123” that the user A has exhibited is acquired.

  The generation unit 315 generates a product description based on the product information and the language information acquired by the acquisition unit 316 (S224B). In this example, a product description in Japanese is generated for the product with the exhibition identifier “123” that the user A has exhibited. This completes the product description generation process.

<<< 3rd Example >>>
The third example of the first embodiment is an example in which a description of a product is generated based on information on a product that a purchasing user has previously exhibited as a selling user.

<< Effect of Third Embodiment >>
According to the present embodiment, an effect is obtained that a product description with an information amount suitable for a purchasing user can be provided. For example, if the purchasing user has previously exhibited a product of the same type as the product for which a display request for the product page has been made as a exhibiting user, it is considered that the purchasing user has a wealth of knowledge about the product. On the other hand, if the same type of product has never been exhibited, knowledge about the product may be poor. Therefore, a product description with a wealth of information is generated for purchasers who have previously sold the same type of product, and a product description with carefully selected moderate information is generated for users who have not exhibited the same type of product. By doing so, it is possible to provide a product description with an information amount suitable for the purchasing user.

<< Functional Configuration of Third Embodiment >>
(1) Functional Configuration of Server The acquisition unit 316 specifies a product that the user B has previously exhibited as an exhibiting user. For example, with reference to the product information table 410A shown in FIG. 5, a product that the user B has exhibited in the past may be specified. Further, the acquisition unit 316 acquires the product information of the specified product. For example, with reference to the product information table 410A shown in FIG. 5, the product information of the products that the user B has exhibited in the past may be acquired.

  The generation unit 315 determines whether the product specified by the acquisition unit 316 and the product requested by the user B to display the product page are the same type of product, and generates a product description based on the determination result. For example, if the product is of the same type, a product description with a large amount of information is generated. If the product is not of the same type, a product description with an appropriately reduced amount of information is generated. The determination as to whether or not the products are the same type may be made based on whether or not the products have a common point. For example, when the category of the product, the model number of the product, and the like are common, the products may be determined to be the same type of product.

<< Operation Process of Third Embodiment >>
With reference to FIG. 13, a description will be given of a process of generating a product description sentence in the server 110A. FIG. 13 is a flowchart illustrating an example of a product page generation process performed by the server 110A according to the first embodiment. Note that the product description generation process shown in FIG. 13 is an example of the process performed in the product description generation step (S220) shown in FIG. In this example, a case will be described as an example where the user B makes a display request for a product page for a product with an exhibition identifier “123” in the product information table 410A shown in FIG.

  First, when the process is started, the acquisition unit 316 of the server 110A acquires the product information of the product that the purchasing user has previously exhibited as the exhibiting user (S221C). For example, with reference to the product information table 410A shown in FIG. 5, a product that the user B has exhibited in the past may be specified. In this example, the product with the exhibition identifier “124” is a product that the user B has previously exhibited as a selling user. The acquisition unit 316 transmits to the generation unit 315 the product information of the product with the exhibition identifier “123” for which the display request of the product page has been received and the product with the exhibition identifier “124” previously exhibited by the user B.

  The generation unit 315 determines whether the product specified by the acquisition unit 316 and the product requested by the user B to display the product page are the same type of product (S222C). In this example, products having the same category are assumed to be the same type of product. Referring to the product information table 410A shown in FIG. 5, the category of the product having the exhibition identifier "123" and the product having the exhibition identifier "124" is the same "book", and thus is determined to be the same type of product. Thereafter, the generation unit 315 generates a product description based on the product information and the determination result (S223C). In this example, a product description with a large amount of information is generated for the product with the exhibition identifier “123”. This completes the product description generation process.

<< 4th Example >>
The fourth example of the first embodiment is an example in which a comment used for communication between users is generated based on at least one of the content of the comment, information on the purchasing user, and information on the exhibiting user.

<< Effect of Fourth Embodiment >>
Comments exchanged between the purchasing user and the selling user are automatically generated. Therefore, the work load of each user in the sale transaction of the product is reduced. In addition, since the comment is generated based on information about each user such as age and gender, an effect that a comment with less discomfort is generated is obtained.

<< Functional Configuration of Fourth Embodiment >>
(1) Functional Configuration of Server The acquiring unit 316 acquires at least one of the information on the purchasing user and the information on the exhibiting user. For example, the information may be obtained by referring to the user attribute information table 430A shown in FIG.

  The generation unit 315 generates a comment used for communication between users. The generation unit 315 generates a comment based on at least one of the content of the comment, information on the purchasing user, and information on the exhibiting user. The content of the comment is the subject of the comment that the user wants to send to another user. For example, thanks for the user who purchased the product, the status of delivery, and the like. The content of the comment is sent from the terminal of the user sending the comment to the server 110A. Since the comment generated by the generation unit 315 is generated based on the information on the purchasing user and the information on the exhibiting user, even if the content of the comment is the same, the text of the generated comment is different if the user is different. For example, when sending a comment from a low-age user to a high-age user, a polite style comment is generated, and when sending a comment from a low-age user to a low-age user of the same age, , A comment with a rough style may be generated.

<< Operation Processing of Fourth Embodiment >>
With reference to FIG. 14, the process of generating a comment in the server 110A will be described. FIG. 14 is a flowchart illustrating an example of a comment generation process performed by the server 110A according to the first embodiment. Here, a case will be described as an example in which a comment for product purchase thanks sent from user A to user B is generated.

  First, the content of the comment is received from the terminal 120A of the user A (S221D). In this example, it is assumed that “purchase thanks” has been received as the content of the comment. The input of the comment content by the user A may be performed via a comment content input screen as shown in FIG.

  Next, the acquisition unit 316 acquires information on the purchasing user and the selling user (S222D). For example, information may be acquired with reference to the user attribute information table 430A shown in FIG. In this example, the attribute information of the user A and the user B is acquired with reference to the user attribute information table 430A.

  The generation unit 315 generates a comment based on the content of the comment, information on the purchasing user, and information on the exhibiting user (S223D). In this example, the user A who sends the comment is 17 years old, and the user B who purchased the product is 55 years old. That is, since the comment is sent from a young user to a high user, a polite style comment such as “Thank you for purchasing this time” may be generated. On the other hand, if the purchasing user is also young, the comment may be generated in a rough style such as “Thank you for buying!”. This completes the comment generation processing.

  With reference to FIG. 15, a description will be given of the work of the user A performed from the time when the user A generates a comment to the time when the comment is transmitted to the user B. FIG. 15A is a diagram illustrating an example of a comment content input screen 121, and FIG. 15B is a diagram illustrating an example of a generated comment editing / transmission screen 122. First, the user A inputs the content of the comment on the input screen 121. At this time, the contents of the comment to be transmitted may be selected from the candidates displayed as shown in FIG. In this example, it is assumed that “purchase thanks” is selected. Then, the content of the selected comment is sent from the terminal 120A to the server 110A, and the generating unit 315 of the server 110A generates the comment.

  The generated comment is transmitted from the server 110A to the terminal 120A, and output by the terminal 120A as shown in FIG. The user A selects the transmission button if the output comment is acceptable, and transmits the comment to the user B. To edit the output comment, the comment can be edited by selecting an edit button.

  Note that the generation unit 315 may generate a plurality of comments. At this time, the generation unit 315 may generate a plurality of comments by changing the degree of importance of the information regarding the purchasing user and the information regarding the exhibiting user. For example, consider a case where the age of the purchasing user is high and the age of the exhibiting user is low. Increasing the degree of importance of the information about the purchasing user generates a comment that is polite in style. On the other hand, if the degree of importance of the information on the exhibiting user is increased, a comment with a rougher style is generated. The user A can select a comment to be transmitted from a plurality of generated comments.

  In addition, the generation unit 315 may generate a comment based on past transaction information between the purchasing user and the selling user. For example, a comment sent to a user with a small number of transactions may be generated in a polite style, and a comment sent to a user with a large number of transactions may be generated in a rough style.

  The above-described process of generating the product description and the comment may be performed in the terminal 120A instead of the server 110A. For example, the terminal 120A may receive, from the server 110A, information serving as a text generation parameter such as product information or user information, and generate a product description or a comment based on the information.

<Second embodiment>
<Overview of Second Embodiment>
In the second embodiment, in a merchandise trading system between users performed via a network, the merchandise information input by the exhibiting user about the exhibited merchandise is compared with the merchandise information of other merchandise, so that an appropriate amount of information on the exhibited merchandise is obtained. It is an embodiment of a method for inputting product information for generating a product page.

  The outline of the invention according to the second embodiment will be described with reference to FIG. As shown in FIG. 16, in the second embodiment, a communication system 1 for buying and selling goods by the server 110 and the terminal 120 is constructed. In the present embodiment, a terminal used by a user (user A) who wants to sell a product is a terminal 120A, and terminals used by already-sold users (user B and user C) are a terminal 120B and a terminal 120C, respectively. . The screen of each terminal shown in FIG. 16 is a screen when each user is inputting product information at the time of selling. As illustrated in FIG. 16, the product image input by the user A is only the front image, and the product information is insufficient compared with the user B and the user C inputting the front and side images. At this time, a message prompting addition of product information (product image on the side) is output to terminal 120A of user A.

<Effect of Second Embodiment>
According to the information input method according to the second embodiment, the product information of the product input by the exhibiting user is compared with the product information of another product, and the difference is specified. The product information of the product sold by the selling user is updated so as to reduce at least a part of the difference. That is, a product page having an appropriate amount of information is generated based on the updated product information. For this reason, the selling user can generate a product page only by inputting a part of the information, or the selling user needs to adjust the amount of information by comparing the product page of the product sold by himself with other product pages. When it disappears, the effect of reducing the burden of product listing work can be obtained. In addition, since a product page with an appropriate amount of information is generated from the beginning when the selling user performs a listing, the frequency at which the product page is corrected afterward is reduced, and the processing load and communication load on the server can be reduced. A smooth transaction is realized.

<Functional Configuration of Second Embodiment>
The functional configuration of the server 110 and / or the terminal 120 will be described with reference to FIG. The functional unit disclosed in FIG. 17 is realized by cooperation of a processor 201, a memory 202, a storage 203, an input / output I / F 204, and a communication I / F 205 included in the information processing apparatus 200. FIG. 17 is a block diagram showing a functional configuration of a communication system 1 for performing a sales transaction of a product between an exhibition user and a purchase user. The communication system 1 includes servers 110A and 110B and terminals 120A, 120B and 120C. including.

(1) Functional Configuration of Server The server 110A includes an input / output I / F 311, a communication I / F 312, a control unit 313, and a storage unit 314. The control unit 313 includes a generation unit 315, an acquisition unit 316, an update unit 317, and a comparison unit 318. The storage unit 314 stores product information 410 and user evaluation information 440 in addition to the program 400. The configuration of the server 110B is the same as that of the server 110A, and a description thereof will be omitted.

  The communication I / F 312 transmits and receives information to and from other terminals and servers including the terminal 120A and the server 110B via the network 130. For example, the product information of the exhibited product is received from the terminal 120A. The communication I / F 312 corresponds to the communication I / F 205 in FIG. 2 described above.

  Generation section 315 generates a message to be transmitted to terminal 120A. For example, when the information input by the user A is insufficient, a message prompting the addition of the product information is generated, and when the information is excessive, a message prompting the reduction of the product information is generated.

  The acquisition unit 316 acquires various information from the storage unit 314. For example, the obtaining unit 316 obtains, from the storage unit 314, product information to be compared in order to determine whether the product information input by the user A is insufficient or excessive. Specifically, the acquisition unit 316 acquires the product information of the product (first product) exhibited by the user A from the product information 410 stored in the storage unit 314. In addition, the same type of product (second product) as the first product is specified, and the product information of the second product is acquired from the product information 410 stored in the storage unit 314. Hereinafter, the product information of the first product is referred to as first product information, and the product information of the second product is referred to as second product information.

  Here, the product of the same type (second product) as the first product refers to a product having a common feature with the first product. For example, when the category of the first product is “wallet”, a product having the same category of “wallet” may be set as the second product. The common point is not limited to the category, but may be a product brand, an exhibitor name, or the like. Note that the acquisition unit 316 may specify one product as the second product, or may specify a plurality of products as the second product.

  The acquisition unit 316 may specify the second product based on a predetermined criterion. For example, a product that has been purchased (a sold product) or a product that has been purchased for a predetermined amount or more may be specified as the second product. Further, a product exhibited by a user who has obtained a rating equal to or higher than a predetermined rating may be specified as a second product. The evaluation of the user will be described later with reference to FIG.

  The update unit 317 updates the first product information so as to reduce at least a part of the difference between the first product information and the second product information specified by the comparison unit 318. Specifically, when the first product information is insufficient compared with the second product information, information is added to the first product information. On the other hand, if the first product information is excessive compared to the second product information, the first product information is reduced.

  The comparing unit 318 compares the first product information and the second product information acquired by the acquiring unit 316, and specifies a difference. Specifically, it is determined whether the information amount of the first information is insufficient or excessive as compared with the information amount of the second information. For example, referring to the product information table 410B shown in FIG. 18, the product information of the product with the exhibition identifier “124” already exhibited by the user 2 includes the information of “category” and “state”. It is not included in the merchandise information of the merchandise with the exhibition identifier “123” exhibited by the user A. As described above, when the specific information included in the second product information is not included in the first information, it may be determined that the first product information is insufficient. On the other hand, although the product information of the product with the exhibition identifier “123” includes the information of “year of use”, it is not included in the product information of the product with the exhibition identifier “124”. As described above, when specific information that is not included in the second product information is included in the first information, it may be determined that the first product information is excessive. It is possible to arbitrarily determine which information is used as a reference to determine whether the first information is insufficient or excessive.

  The storage unit 314 stores product information 410 and user evaluation information 440 in addition to the program 400. The product information 410 and the user evaluation information 440 will be described with reference to FIGS.

  First, the product information 410 will be described. Part of the product information 410 is managed in the product information table 410B. FIG. 18 is a diagram illustrating an example of the product information table 410B. The product information table 410B includes “product identifier”, “exhibition identifier”, “product model number”, “category”, “state”, “image”, “seller name”, “purchase record”, “purchase amount”, There is a column of “years of use”, and corresponding information is managed for each column. The information included in the product information table 410B is not limited to these, and may include arbitrary product information.

  In the column of "product identifier", a product identifier assigned to each product is managed. The product identifier is information for identifying the product, and the same product is provided with the same product identifier. Since the same product identifier “111” is assigned to all the products shown in FIG. 18, it can be seen that the products are the same.

  In the column of “exhibition identifier”, an identifier for identifying a commodity for sale is managed. Even if the products are of the same product type number or category, a different exhibition identification is assigned to each product. Although the products shown in FIG. 18 are all the same products as described above, different exhibition numbers from "123" to "126" are assigned to each product.

  The column of “product name” manages the names of the products for sale. Since the product names input by the respective users are managed as they are, different product names may be managed even for the same product (product having the same product identifier). In the case of this example, the product name of the product with the exhibition identifier “123” is “Ari 001”, the product name of the product with the exhibition identifier “124” is “Ari001”, and the product name of the product with the exhibition identifiers “125” and “126” Is “Yes-001”.

  In the column of "product model number", product model numbers are managed. The model number is a number assigned by a manufacturer that manufactures the product, and is determined based on, for example, the date and place where the product was manufactured. Note that the product model number may include a character string. In the case of this example, it is indicated that the product model number of the products with the exhibition identifiers “123”, “124”, “125”, and “126” is “Ally001”.

  The column of “category” manages the category of the exhibited product. Not limited to the categories shown in FIG. 18, categories such as “small articles” which is a superordinate concept of “wallet” and “long purse” which is a subordinate concept may be managed. In the case of this example, it is indicated that the category information is not managed for the product with the exhibition identifier “123”. On the other hand, it is shown that the category of the products with the exhibition identifiers “124”, “125”, and “126” is “wallet”.

  In the column of “state”, information on the use state of the product is managed. In the column of “state” of the product information table 410B shown in FIG. 18, information as to whether the exhibited product is new or used is managed.

  In the column of "image", information on the image of the exhibited product is managed. The product information table 410B shown in FIG. 18 manages information on which side of the product the product image stored in the storage unit 314 is. In the case of this example, only the image of “front” is input for the product with the exhibition identifiers “123” and “126”, and the image of “front / side” is input for the product with the exhibition identifiers “124” and “125”. Is entered. The product image may be stored in the storage unit 314 separately from the product information table 410B.

  The column of “seller name” manages the names of the users who have sold the products. Since the information is included in the product information, it is possible to specify which user has sold each product. In the case of this example, the products with exhibition identifiers "123", "124", "125", and "126" are exhibited by "User A", "User B", "User C", and "User D", respectively. I have.

  In the column of “purchase record”, information as to whether or not the product has already been purchased is managed. In the product information table 410B shown in FIG. 18, "sold out" is displayed for products already purchased, and "sold" for products not yet purchased. In the case of this example, it is indicated that the products with the exhibition identifiers “123” and “126” are “sold” and the products with the exhibition identifiers “124” and “125” are “sold out”.

  The column of “purchase amount” manages the amount of the purchased item. In the product information table 410B shown in FIG. 18, the purchase price is displayed in the record of the product already purchased, and the price is not displayed in the record of the product not yet purchased. In the case of this example, since the products with the exhibition identifiers "123" and "126" are on sale, the purchase price is not shown. On the other hand, it is shown that the products with the exhibition identifiers “123” and “124” were purchased at “5500 yen” and “2700 yen”, respectively. Naturally, the price at the time of exhibition may be included in addition to the purchase price.

  The column of “years of use” manages the number of years that the user has used the product. In the case of this example, the exhibition identifier “123” indicates that the number of years of use is “2 years”. On the other hand, the years of use of the products with the exhibition identifiers “124”, “125”, and “126” are not managed.

  Next, the user evaluation information will be described. FIG. 19 is a diagram illustrating an example of the user evaluation information table 440B. The user evaluation information 440 will be described with reference to FIG.

  The user evaluation information table 440B shown in FIG. 19 manages the user evaluation information of each user. In the user evaluation information table 440B in the present embodiment, “user name” and “user evaluation information” are managed.

  “User evaluation information” is a result of an evaluation performed by another user on a user. In the present embodiment, the evaluation is performed by giving numbers from 0 to 5, and the average value of the numerical values is stored in the user evaluation information table 440B as the user evaluation information. The target of the evaluation may be the quality of the response of the user, the richness of the information included in the product page, or the like. In the case of this example, the evaluations of “user A”, “user B”, “user C”, and “user D” are “4.7”, “1.4”, “3.8”, and “2. 7 ".

  Further, in the present embodiment, the user evaluation is performed using numerical values, but the present invention is not limited to the evaluation method using numerical values. For example, a character such as “like” or a specific design may be displayed on a terminal used by the user performing the evaluation, and the evaluation may be performed by the user performing the evaluation selecting the character or the design. In that case, the number of users who have selected characters such as “like” or a specific symbol may be stored in the user evaluation information table 440B.

  As described above, the acquisition unit 316 may specify, as a second product, a product exhibited by a user who has obtained an evaluation equal to or higher than a predetermined evaluation.

(2) Functional Configuration of Terminal The functional configuration of the terminal 120 according to the second embodiment is the same as the functional configuration of the terminal 120 according to the first embodiment, and a description thereof will not be repeated.

<Operation Processing of Second Embodiment>
The processing of the communication system 1 according to the second embodiment will be described with reference to FIG. FIG. 20 illustrates an example of a processing sequence of the communication system 1 according to the second embodiment. FIG. 20 shows that after the first product information is input by the terminal 120A, the server compares the first product information and the second product information to identify a difference, and performs the first process so as to reduce at least a part of the difference. This is a sequence for updating product information.

  First, an exhibition request is transmitted from the terminal 120A to the server 110A (S50). The exhibition request is an indication of a user's intention to sell the product, and for example, the user can make an exhibition request by selecting a specific icon or the like displayed on the terminal 120A.

  Next, the server 110A generates an input screen for the first product information (S52) and transmits it to the terminal 120A (S54). The product information input screen may be configured with information items required to be input by the exhibiting user, information entry columns, and the like.

  The user A inputs the product information according to the first product information input screen received by the terminal 120A (S56), and transmits the first product information to the server 110A. Here, the first product information may be transmitted from the terminal 120A to the server 110A each time each input item is input. At this time, the server 110A may guess or specify other first product information from some of the received first product information, and update the input screen of the first product information based on the guessed information. . For example, when the product model number is input by the user A, the server 110A estimates or specifies other product information such as size information or a product name based on the product model number, and adds the information to the first product information input screen. May be. By doing so, the burden on the user A for inputting the first product information is reduced. The acquisition unit 316 of the server 110A that has received the first product information specifies a second product of the same type as the first product from among other exhibited products based on the first product information (S58). For example, referring to the product information table 410B shown in FIG. 18, a product in the same category as the first product may be specified as the second product.

  Thereafter, the acquisition unit 316 acquires the first product and the second product information (S60). For example, the second product information may be acquired with reference to the product information table 410B shown in FIG.

  Next, the comparison unit 318 of the server 110A compares the first product information with the second product information and specifies a difference (S62). The update unit 317 of the server 110A updates the first product information so as to reduce at least a part of the difference (S64). At this time, the server 110A may transmit a message prompting the addition or reduction of the first product information to the terminal 120A, or may perform the addition or reduction of the information on the first product information without transmitting the message. Good.

  Thereafter, the generation unit 315 of the server 110A generates a product page of the first product based on the first product information (S66).

<< 1st Example >>
In the first example of the second embodiment, when the first product information received from the user A is insufficient compared with the second product information, a message prompting the addition of the product information is transmitted to the terminal 120A. It is an example.

<< Effect of First Embodiment >>
When the first product information is insufficient compared to the second product information, a message urging the addition of the first product information is transmitted from server 110A to terminal 120A. Therefore, the user A can recognize that the first product information is insufficient through the terminal 120A. In addition, by adding the first product information in accordance with the message prompting the addition, an effect that an exhibition page with an appropriate amount of information is generated is obtained.

<< Functional Configuration of First Embodiment >>
(1) Functional Configuration of Server When the first product information is insufficient compared with the second product information, the generation unit 315 generates a message prompting the addition of product information. For example, in the product information table 410B shown in FIG. 18, if the product with the exhibition identifier "123" is the first product and the product with the exhibition identifier "124" in the same category "Wallet" is the second product, the second product It is assumed that the information includes the side image of the product, whereas the first product information does not include the side image of the product, so the first product information is assumed to be insufficient. At this time, the generation unit 315 generates a message prompting the addition of the first product information. For example, a message such as “Let's take a picture of the side!” Displayed on the terminal 120A shown in FIG. 16 may be generated.

<< Operation Processing of First Embodiment >>
With reference to FIG. 21, a message generation process according to the present embodiment will be described. FIG. 21 is a flowchart illustrating an example of a message generation process performed by the server 110A.

  First, the comparison unit 318 compares the first product information with the second product information (S300). Specifically, the records managed in the product information table 410B are compared with each other. In this example, the merchandise information with the merchandise with the exhibition identifier “123” is set as the first merchandise and the merchandise with the merchandise identifier “124” is set as the second merchandise, and the merchandise information is compared.

  When the first product information is insufficient (S301: Yes), the generation unit 315 generates a message urging the addition of the product information, and the communication I / F 312 transmits the message to the terminal 120A (S302). In the case of this example, the second product information includes the side image of the product, whereas the first product information does not include the side image of the product. Therefore, the generation unit 315 determines that the first product information is insufficient, and sends a message prompting the addition of product information such as “Let's take a picture of the side!” Displayed on the terminal 120A in FIG. Generate.

  Thereafter, the communication I / F 312 receives additional first product information (additional information) from the terminal 120A (S303). The updating unit 317 additionally updates the first product information based on the additional information (S304). Specifically, the product information table 410B shown in FIG. 18 is updated based on the additional information. In the case of this example, when the side image of the first product is received from the user A, the updating unit 317 updates the column of “image” for the record of the exhibition identifier “123” in the product information table 410B.

  The generation unit 315 generates a product page based on the updated first information (S305). If the first product information is not insufficient (S301: No), a message page is generated based on the first product information without generating and transmitting a message (S305). This completes the product page generation processing by the server 110A.

  FIG. 22 shows a state where the generated message is output to terminal 120A. The message generated by the generation unit 315 that prompts the addition of the product information may include an input candidate sentence generated based on a word included in the second product information. In the product information table 410B shown in FIG. 18, a case will be described as an example where the first product is a product with the exhibition identifier "123" and the second product is a product with the exhibition identifiers "124" and "125". Referring to the product information table 410B, the product information of the product (second product) with the product identifiers “124” and “125” includes the product status information, whereas the product identifier of the product identifier “123” (first product) is included. The product information of the product does not include the status information of the product. At this time, the generation unit 315 may generate a message in which the words “new” and “used” included in the state information of the second product information as shown in FIG. 22 are input candidate sentences. The user A can easily add product information by selecting any of the input candidate sentences.

<< 2nd Example >>
The second example of the second embodiment is an example of automatically adding product information when the first product information received from the user A is insufficient compared with the second product information.

<< Effect of Second Embodiment >>
When the first product information is insufficient compared with the second product information, the server 110A estimates the missing product information based on the first product information, and automatically adds the first product information. For this reason, an exhibition page having an appropriate amount of information is generated without the user himself / herself adding missing product information, and the effect of reducing the burden of the exhibition operation can be obtained.

<< Functional Configuration of Second Embodiment >>
(1) Functional Configuration of Server When the first product information received from the user A is insufficient compared with the second product information, the generation unit 315 determines that the first product information is insufficient from the input first product information. Estimate additional information that supplements the information. For example, in the product information table 410B shown in FIG. 18, if the product with the exhibition identifier "123" is the first product and the product with the exhibition identifier "124" is the second product, the category information of the product is included in the second product information. While the first product information is included, the first product information is insufficient because the first product information does not include the category information of the product. At this time, the generation unit 315 may estimate the category information of the first product as additional information from the product model number information of the first product. Specifically, the category may be specified by referring to the product information of the product having the same product model number. When the product information includes a product image, missing information may be generated based on the product image.

  The update unit 317 adds the first product information based on the additional information estimated by the generation unit 315. Specifically, the product information table 410B shown in FIG. 18 is updated.

<< Operation Process of Second Embodiment >>
With reference to FIG. 23, updating of product information according to the present embodiment will be described. FIG. 23 is a flowchart illustrating an example of updating product information executed by the server 110A. Here, when the comparison unit 318 compares the first product information input by the user A with the second product information acquired by the acquisition unit 316, additional information is estimated when the first product information is insufficient. An example of addition will be described.

  First, the comparison unit 318 compares the first product information with the second product information (S300). Specifically, the records managed in the product information table 410B are compared with each other. In this example, the merchandise information with the merchandise with the exhibition identifier “123” is set as the first merchandise and the merchandise with the merchandise identifier “124” is set as the second merchandise, and the merchandise information is compared.

  When the first product information is insufficient (S301: Yes), the generation unit 315 estimates additional information that supplements the missing first product information from the input first product information (S310). In this example, the generation unit 315 may estimate the category information from the information of the product model number. For example, since the category of the second product having the product model number “Ally001” is “wallet”, the category of the first product having the same product model number may be estimated as “wallet”.

  The update unit 317 additionally updates the first product information with the additional information (S312). Specifically, the product information table 410B shown in FIG. 18 is updated based on the additional information. In the present example, the update is performed such that the category information of the first product is “wallet”.

  The generation unit 315 generates a product page based on the updated first product information (S313). If the first product information is not insufficient (S301: No), a product page is generated based on the first product information without estimating additional information (S313). This completes the product page generation processing by the server 110A.

<<< 3rd Example >>>
A third example of the second embodiment is an example in which, when the first product information received from the user A is excessive compared to the second product information, a message urging the reduction of the product information is transmitted to the terminal 120A. It is.

<< Effect of Third Embodiment >>
When the input first product information is excessive compared to the second product information, a message urging the reduction of the first product information is transmitted from the server 110A to the terminal 120A. Therefore, the user A who has put up the first product can easily recognize that the first product information is excessive. In addition, by performing the reduction of the first product information in accordance with the message prompting the reduction, an effect that an exhibition page with an appropriate information amount is generated is obtained.

<< Functional Configuration of Third Embodiment >>
(1) Functional Configuration of Server When the first product information received from the user A is excessive compared to the second product information, the generation unit 315 generates a message that prompts the user to reduce product information. For example, in the product information table 410B shown in FIG. 18, when the product with the exhibition identifier “123” is the first product and the product with the exhibition product “124” is the second product, the information on the number of years of use is included in the first product information. While it is included, it is not included in the second product information. At this time, the generation unit 315 may generate a message urging the user A to reduce the first product information (information on the number of years of use). Note that the information reduction includes deletion and reduction of information.

<< Operation Process of Third Embodiment >>
With reference to FIG. 24, a message generation process according to the present embodiment will be described. FIG. 24 is a flowchart illustrating an example of a message generation process performed by the server 110A. Here, an example of transmitting a message urging the user A to reduce the product information when the first product information is excessive as a result of the comparison unit 318 comparing the first product information and the second product information is described. explain.

  First, the comparison unit 318 compares the first product information with the second product information (S300). Specifically, the records managed in the product information table 410B are compared with each other. In this example, the merchandise information with the merchandise with the exhibition identifier “123” is set as the first merchandise and the merchandise with the merchandise identifier “124” is set as the second merchandise, and the merchandise information is compared.

  When the first product information is excessive (S320: Yes), the generation unit 315 generates a message urging the reduction of the product information, and the communication I / F 312 transmits the message to the terminal 120A (S321). In the case of this example, the first product information includes information on the years of use of the product, whereas the second product information does not. Therefore, the comparison unit 318 determines that the first product information is excessive, and the generation unit 315 generates a message urging deletion of the information on the number of years of use.

  Thereafter, the communication I / F 312 receives a reduction instruction from the terminal 120A for instructing reduction of the product information (S322). The update unit 317 reduces and updates the first product information based on the reduction instruction (S323). Specifically, the product information table 410B shown in FIG. 18 is updated based on the reduction instruction. In the case of this example, when receiving an instruction to delete the information on the number of years of use from the terminal 120A, the updating unit 317 deletes the information on the number of years of use from the record of the first product information in the product information table 410B.

  The generation unit 315 generates a product page based on the updated first information (S324). If the first product information is not excessive (S320: No), a message page is generated based on the first product information without generating and transmitting a message (S324). This completes the product page generation processing by the server 110A.

<< 4th Example >>
The fourth example of the second embodiment is an example in which a message urging the addition of product information is transmitted to the terminal 120B when the first product information received from the user A is excessive compared to the second product information. It is.

<< Effect of Fourth Embodiment >>
When the input first product information is excessive compared to the second product information, a message urging the addition of the second product information is transmitted from server 110A to terminal 120B. That is, when the product information of the second product already sold is less than the product information of the first product newly sold, the fact is notified to the user B who has sold the second product. Therefore, the user B who has exhibited the second product can easily recognize that the second product information is insufficient. Further, by adding the second product information in accordance with the message prompting the addition of the product information, an effect is obtained that an exhibition page having an appropriate information amount for the second product is generated.

<< Functional Configuration of Fourth Embodiment >>
(1) Functional Configuration of Server When the first product information is excessive compared with the second product information, the generation unit 315 generates a message prompting the addition of the second product information. For example, in the product information table 410B shown in FIG. 16, if the product with the exhibition identifier “123” is the first product and the product with the exhibition product “124” is the second product, the information on the years of use is included in the first product information. While it is included, it is not included in the second product information. At this time, a message is generated that prompts the user to add information on the number of years of use of the second product information.

<< Operation Processing of Fourth Embodiment >>
With reference to FIG. 25, a process of generating a product page according to the present embodiment will be described. FIG. 25 is a flowchart illustrating an example of a product page generation process performed by the server 110A. Here, as a result of the comparison unit 318 comparing the first product information input by the user A with the second product information acquired by the acquisition unit 316, if the first product information is excessive, An example of transmitting a message prompting the addition of information will be described.

  First, the comparison unit 318 compares the first product information with the second product information (S300). Specifically, the records managed in the product information table 410B are compared with each other. In this example, the merchandise information with the merchandise with the exhibition identifier “123” is set as the first merchandise and the merchandise with the merchandise identifier “124” is set as the second merchandise.

  When the first product information is excessive (S320: Yes), the generation unit 315 generates a message prompting the addition of the second product information, and the communication I / F 312 transmits the message to the terminal 120B (S330). In the case of this example, the first product information includes information on the years of use of the product, whereas the second product information does not. Therefore, the generation unit 315 generates a message that prompts the user to add information on the number of years of use.

  Thereafter, the communication I / F 312 receives additional information for adding the second product information from the terminal 120B (S331). The updating unit 317 updates the second product information based on the additional information (S332). Specifically, the product information table 410B shown in FIG. 16 is updated based on the additional information. In the case of this example, when the information on the years of use is received from the terminal 120B, the updating unit 317 adds the information on the years of use to the record of the second product information in the product information table 410B.

  The generation unit 315 generates a product page based on the updated second product information (S333). If the first product information is not excessive (S320: No), the generation and transmission of the message are not performed. This completes the product page generation processing by the server 110A.
