[data structure]
Next, specific examples of the data structures of the product information DB 131, the privilege granting condition DB 132, and the purchase history DB 133 stored in the server device 1 will be described.

  FIG. 4A is an example of the data structure of the product information DB 131. In the product information DB 131 shown in FIG. 4A, a point return rate for calculating the title, author, price, and return points of a book as a product is associated with each product ID. Here, the “price” in FIG. 4A indicates the price of the book before the privilege based on the purchase history is reflected, and the “point return rate” in FIG. 4A is given to the price. Indicates the rate of power reduction points. For example, when the book “XX Case 1st volume” with the product ID “B10001” is purchased and the privilege based on the purchase history is not applied, the price is “500 yen” and the return point is “5 points” (= 500 × 0.01). In addition to the items shown in FIG. 4A, the product information DB 131 may be associated with various information such as book genre information, publisher information, and publication date information. Note that the price does not necessarily have to be a fixed price, and when a discount is implemented for reasons other than the application of the privilege based on the purchase history, the price after the discount is indicated.

  FIG. 4B is an example of the data structure of the privilege grant condition DB 132. In the privilege granting condition DB 132 shown in FIG. 4B, the target product ID that is the product ID of the product that is the subject of the privilege grant, the related product ID that is the product ID of the product related to the product, and the privilege content. Associated.

  Here, when the first record of the privilege granting condition DB 132 is to purchase the electronic book “XX case first volume (electronic version)” with the product ID “E10001”, the book “○ with the product ID“ B10001 ”which is a related product. ○ Indicates that the price will be 70% discount when there is a purchase history of “Case 1st volume”. As described above, by giving a privilege to the purchase of an electronic book having the same title to a user who has purchased a paper book, it is possible to favorably promote the sale of the electronic book.

  Further, the second record of the privilege granting condition DB 132 indicates that when purchasing the electronic book “XX case 2” of product ID “B10002”, the book “XX case 1” of product ID “B10002”, which is a related product, is purchased. This indicates that when there is a purchase history, a reduction point corresponding to 10% of the price is added. Further, the third record of the privilege granting condition DB 132 indicates that, when purchasing the electronic book “Invitation to Vol. 3” with the product ID “B10005”, the book “ΔΔ” with the product ID “B10003” which is a related product. No. 1 ”or the book“ Invitation to △△ Volume 2 ”with the product ID“ B10004 ”has a purchase history of 2 points. In this way, when one of the books of the same title (ie, books in series) that differ only in the number of volumes (volume name) has been purchased, it is based on the purchase history when purchasing other books in the same series. By attaching a privilege, book sales can be favorably promoted.

  FIG. 4C is an example of the data structure of the purchase history DB 133. In the purchase history DB 133 shown in FIG. 4C, a product ID corresponding to a purchased product is associated with each user ID. The server device 1 updates the purchase history DB 133 every time a product transaction is established. For example, when there is a product purchase procedure on the product screen, the server device 1 registers the product ID of the purchased product in the purchase history DB 133 in association with the user ID corresponding to the purchaser. In the case of store sales, the server device 1 receives the purchaser's user ID read by the POS register from the membership card, etc., and the product ID read by the POS register from the tag attached to the product. The purchase history DB 133 is updated.

[Processing flow]
Next, the display method of the product screen based on this embodiment will be described with reference to the flowcharts of FIGS.

(1) Process Overview FIG. 5 is an example of a flowchart showing a process procedure executed by the server device 1 and the user terminal 3 when displaying a product screen.

  First, the user terminal 3 transmits login information such as a user ID necessary for login to the server device 1 (step S101). For example, the user terminal 3 displays a login screen or the like based on the display information received from the server device 1, thereby accepting input such as a user ID for performing login, and transmits the input information to the server device 1. To do. In this case, the server device 1 performs user authentication based on the received login information (step S201). Thereby, the server device 1 recognizes the user ID of the user of the user terminal 3.

  Next, the user terminal 3 receives an input for designating the display target product Ctag and transmits the input information to the server device 1 (step S102). In this case, the input for specifying the display target product Ctag may be a keyword for searching for each product stored in the product information DB 131, and the product ID, publisher, publication year for specifying a desired book. Month and / or genre may be used. The server device 1 that has received the input information designating the display target product Ctag from the user terminal 3 recognizes the display target product Ctag by performing a product search on the product information DB 131 based on the input information, and displays the display target. The product information of the product Ctag is acquired from the product information DB 131 (step S202).

  And the server apparatus 1 performs the privilege provision process mentioned later for every display object goods Ctag (step S203). Thereby, the server apparatus 1 determines the price or return point of the display target product Ctag to which the privilege based on the purchase history is applied. And the server apparatus 1 produces | generates the display information of a goods screen based on the product information of the display object goods Ctag acquired at step S202, and the result of the privilege provision process at step S203, and transmits to the user terminal 3 (step) (step S202). S204). The user terminal 3 that has received the display information of the product screen displays the product screen based on the display information (step S103). A display example of the product screen in step S103 will be described later with reference to FIG.

  Thereafter, when the product to be purchased is designated on the product screen, the server device 1 performs a settlement for purchasing the designated product. In this case, when the product to be purchased is the application target of the privilege based on the purchase history, the server device 1 performs settlement with the price or the reduction point after the privilege is applied.

(2) Bonus Granting Process FIG. 6 is an example of a flowchart showing the procedure of the privilege granting process. The server apparatus 1 performs the privilege provision process shown in FIG. 6 for every display object product Ctag in step S203.

  First, the server device 1 refers to the privilege granting condition DB 132 and determines whether there is a related product ID associated with the product ID of the display target product Ctag (step S211). And the server apparatus 1 advances a process to step S212, when the related goods ID linked | related with goods ID of display object goods Ctag is registered into privilege provision condition DB132 (step S211: Yes). On the other hand, when the related product ID linked to the product ID of the display target product Ctag is not registered in the privilege granting condition DB 132 (step S211: No), the server device 1 is based on the purchase history for the display target product Ctag. It is determined that there is no privilege, and the process of the flowchart ends.

  Next, the server device 1 determines whether or not the related product ID recognized in step S211 is associated with the target user ID in the purchase history DB 133 (step S212). Here, the “target user ID” is the user ID recognized by the user authentication in step S201 of FIG. Thereby, the server device 1 determines whether or not there is a purchase history of a book related to the display target product Ctag.

  If the related product ID is associated with the target user ID in the purchase history DB 133 (step S212; Yes), the server device 1 changes the price or return point of the display target product Ctag (step S213). Specifically, the server apparatus 1 determines the price or return point of the display target product Ctag registered in the product information DB 131 based on the privilege content associated with the product ID of the display target product Ctag and the privilege granting condition DB 132. change. Thereby, the server apparatus 1 can display the product screen in which the privilege based on the purchase history is appropriately reflected on the display target product Ctag related to the purchased product on the user terminal 3. On the other hand, when the identified related product ID is not associated with the target user ID in the purchase history DB 133 (step S212; No), the server device 1 determines that there is no purchase history of the related book of the display target product Ctag, The process of the flowchart is terminated without reflecting the privilege based on the purchase history.

[Display example]
FIG. 7 shows a display example of a product screen on which a privilege based on the purchase history is reflected. In the example of FIG. 7, the user terminal 3 used by the user with the user ID “1001”, after logging in to the server apparatus 1, the server apparatus 1 displays the input information with “XX” as a search condition together with a display information request signal. The product screen is displayed by sending to. In the example of FIG. 7, the server device 1 preferentially displays the display target product Ctag to which the privilege based on the purchase history is given (that is, at the top).

  Here, the process which produces | generates the display information of the goods screen shown in FIG. 7 is demonstrated concretely.

  First, when the server apparatus 1 receives input information using “XX” as a search condition, the server apparatus 1 searches for a title in the product information DB 131 using “XX” as a keyword, and stores the product ID “E10001” shown in FIG. ”Is recognized as a display target product Ctag (see step S202 in FIG. 5). The product including the electronic book“ XX case first volume (electronic version) ”and the product ID“ B10002 ”book“ XX case second volume ”is recognized.

  Then, the server apparatus 1 performs the determination process of the presence or absence of application of the privilege based on a purchase history, and the application process of a privilege with respect to each display object goods Ctag by the privilege provision process of FIG.

  For example, in the case of the electronic book “XX case first volume (electronic version)” of the product ID “E10001” which is one of the display target products Ctag, the server device 1 sets the corresponding related product ID “B10001” to the privilege granting condition DB 132. (See step S211 in FIG. 6), and recognizes that the related product ID “B10001” is registered in the purchase history DB 133 related to the user ID “1001” (see step S212). Accordingly, the server device 1 reflects the “price 70% OFF”, which is the privilege content registered in the privilege granting condition DB 132, in the price of the electronic book “XX case first volume (electronic version)” (see step S213). As a result, in the example of FIG. 7, the price of the electronic book “XX case 1st volume (electronic version)” is set to “150 yen”, which is 7 discounts of the price “500 yen” registered in the product information DB 131. Yes. In the example of FIG. 7, the server device 1 displays that the privilege based on the purchase history is applied together with the price and the return point.

  Further, in the case of the book “XX case second volume” with the product ID “B10002”, the server apparatus 1 extracts the corresponding related product ID “B10001” from the privilege granting condition DB 132, and the related product ID “B10001” is It is recognized that the user ID “1001” is registered in the purchase history DB 133. Therefore, the server apparatus 1 reflects the “point return for 10% of the price”, which is the privilege content registered in the privilege granting condition DB 132, in the return point. As a result, in the example of FIG. 7, the reduction point of the book “XX Case Volume 2” is normally “5 points” (1% of the price of 500 yen), whereas “55 points” (the price of 500 yen) 11%). In the example of FIG. 7, the server device 1 displays that the privilege based on the purchase history is applied together with the price and the return point.

  In the example of FIG. 7, the server device 1 displays only the price or return point after applying the privilege based on the purchase history for each display target product Ctag. Instead of this, the server device 1 may write the price or return point before applying the privilege based on the purchase history and the price or return point after applying the privilege based on the purchase history on the product screen. For example, in the case of the electronic book “XX case first volume (electronic version)” with the product ID “E10001”, the server device 1 gives the price “500 yen” before applying the privilege based on the purchase history, and the privilege based on the purchase history. You may display on the goods screen of FIG. 7 with the price "150 yen" after application. Similarly, in the case of the book “XX case, second volume” with the product ID “B10002”, the server device 1 uses the return point “5 points” before applying the benefit based on the purchase history, and applies the benefit based on the purchase history. You may display on the goods screen of Drawing 7 with return point "55 points".

[Effects of trading system]
According to the transaction system 100 of the embodiment, the server device 1 suitably sells related books of purchased books by applying a privilege based on a purchase history such as a discount to books related to the purchased books. Can be promoted.

[Modification]
Next, a modification of the embodiment will be described. The following modifications may be applied in any combination to the above-described embodiment.

(Modification 1)
In the example of the privilege granting condition DB 132 shown in FIG. 4B, the privilege object based on the purchase history is set to an electronic book having the same title with respect to a paper book or a book in the same series as a purchased book. . However, the privilege target based on the purchase history is not limited to this.

  For example, benefits based on purchase history include back numbers for purchased books, purchased books and authors with the same book, or purchased books and books with the same age (age), purchased books and publication date May be the same book or the like. Examples of books with the same age (age) for sale include magazines for first graders and teaching materials for university entrance exams. Moreover, as an example of a book with the same publication time, for example, a comic published in the same age corresponds.

  In another example, the privilege target based on the purchase history may be a book whose title and title completely or partially match in a sentence explaining the purchased book, such as a product description of the purchased book or a user review. Good. In yet another example, the privilege target based on the purchase history may be a book whose title partially matches the purchased book. As described in the second modification, the server device 1 may automatically perform registration processing in the privilege granting condition DB 132 regarding these books by referring to the product information DB 131.

(Modification 2)
The server device 1 may automatically generate each record in the privilege granting condition DB 132 by referring to the product information DB 131.

  For example, the server device 1 refers to the item “title” in the product information DB 131 and performs registration processing in the privilege granting condition DB 132 for books of the same series. In this case, for example, the server device 1 sets the product ID of the book with the larger number of turns as the target product ID and the product ID of the book with the smaller number of turns as the related product ID for two books with the continuous number of turns. . In addition, the server apparatus 1 may set the privilege content set in this case to a predetermined content, for example, and may determine for every user based on the modification 4 mentioned later.

  In another example, the server device 1 automatically searches for a book name that appears in a sentence explaining or evaluating a product, such as a product description or a user review, and a product ID corresponding to the book name detected more than a predetermined number of times. The product ID of the book whose description is the search target is registered in association with the privilege granting condition DB 132.

  In yet another example, the server device 1 searches for books whose titles match at a predetermined rate or more, sets each product ID of the book as a target product ID, and sets the product IDs of other searched books as related product IDs. As, you may register into privilege grant condition DB132.

  Note that the server device 1 refers to the product information DB 131 after recognizing the display target product Ctag instead of automatically generating each record of the privilege granting condition DB 132 and includes the purchased book registered in the purchase history DB 133. It may be determined whether there is a book related to the display target product Ctag. That is, the server device 1 refers to only the product information DB 131 without referring to the privilege granting condition DB 132 in which related products are associated with each other, thereby determining whether there is a purchased book related to each display target product Ctag. You may judge. When the server device 1 determines that there is a book related to the display target product Ctag among the purchased books registered in the purchase history DB 133, the server device 1 applies a privilege based on the purchase history to the display target product Ctag. To do. The privilege content set in this case may be predetermined content, for example, or may be privilege content based on Modification Example 4 described later.

(Modification 3)
When two or more books are designated as books to be purchased, the server device 1 corresponds to a combination of a target product ID registered in the privilege granting condition DB 132 and a related book indicated by the related product ID among these books. When there is a book set that satisfies the conditions for granting a privilege, the privilege may be applied.

  For example, a user who does not have a purchase history can read a book “XX case first volume” with a product ID “B10001” and a book “XX case first volume (electronic version)” with a product ID “E10001” in the product information DB 131 shown in FIG. A case where a plurality of books including "" are designated on the product screen as products to be purchased will be described.

  In this case, the server device 1 corresponds to the combination of the related product indicated by the target product ID and the related product ID registered in any record of the privilege granting condition DB 132 for any two books selected as the products to be purchased. It is determined whether or not (a combination that satisfies a condition for granting a privilege). In this example, the server device 1 recognizes that the combination of the book indicated by the target product ID and the related product ID of the first record in the privilege granting condition DB 132 shown in FIG. To do. Therefore, in this case, the server apparatus 1 recognizes that the book “XX case first volume (electronic version)” with the product ID “E10001” is a privilege object, and the book “XX case first volume (electronic) with the product ID“ E10001 ”. Version) "is turned off by 70%.

  As described above, the server device 1 is a case where two or more books are purchased at the same time, and when there are books related to each other, that is, when there is a combination of books satisfying a condition for granting a privilege, By giving a privilege to at least one of them, it is possible to favorably promote simultaneous purchase (that is, bulk purchase) of related books.

(Modification 4)
The server device 1 may change the content of the privilege based on the purchase history based on the purchase history of the user.

  In the first example, the server device 1 changes the privilege content stepwise or continuously in accordance with the cumulative number of logged-in users. In this case, for example, the server device 1 gives a discount (for example, 30% off) to a user whose cumulative purchase number registered in the purchase history DB 133 is a predetermined number (for example, 100) or more, and the cumulative purchase number is less than the predetermined number. Greater than discounts for users (eg 20% off). That is, when purchasing a product for which a privilege is to be granted, the privilege to be granted can be set stepwise or continuously in accordance with the cumulative number of purchases by the user.

  In the second example, when a book with the same title that differs only in the number of turns is the display target product Ctag, the server device 1 changes the privilege content stepwise or continuously according to the number of purchases of the book with the same title. . For example, the server device 1 has a purchase history of the ninth volume, which is the number of volumes immediately before the tenth volume, in the case where the tenth volume is a purchase target in a book of a series having a volume number of up to “10”. If there is a purchase history of all books from Volume 1 to Volume 9 before Volume 10, discount 50%. The books having the same titles in the first to tenth volumes in this example are examples of “a product with matching attributes” in the present invention.

  Similarly to the second example, the server device 1 provides the privilege content stepwise or continuously according to the number of books purchased by the same author as the display target product Ctag and the number of books purchased by the same publisher as the display target product Ctag. May be varied. In this case, the book of the same author and the book of the same publisher are examples of the “product with matching attributes” in the present invention.

  That is, when purchasing a product for which a privilege is to be granted, a privilege to be granted can be set stepwise or continuously in accordance with the number of purchases of a product having the same attribute such as the same title and the same author.

(Modification 5)
Instead of applying a privilege based on the purchase history to electronic commerce using the user terminal 3, a privilege based on the purchase history may be applied to purchase at the store.

  FIG. 8 shows a trading system 100A according to a modification. As shown in FIG. 8, the transaction system 100 </ b> A includes a POS register terminal device 4 that is connected to the server device 1 via the communication network 2. The POS register terminal device 4 has a reader / writer 40 and reads a membership number (that is, a user ID) when a membership card or a portable terminal owned by a purchaser is held over the reader / writer 40.

  The POS register terminal device 4 transmits the product ID and the user ID to the server device 1 when the product ID of the product to be purchased is read by a bar code reader (not shown) or the like. In this case, the server device 1 performs the privilege granting process of FIG. 6 for the received product ID, and when there is a purchase history of related products, the privilege content registered in the privilege granting condition DB 132 is stored in the POS register terminal. Notify the device 4. Then, the POS register terminal device 4 reflects the notified privilege content on the payment amount and the return point. Instead of the above example, the server device 1 may calculate a price or return point after reflecting a privilege based on the purchase history, and notify the POS register terminal device 4 of the price information.

  Thus, discounts for books related to purchased books can be suitably executed for purchases in stores.

(Modification 6)
The products handled by the transaction system 100 need not be limited to books. For example, in addition to or instead of a book, the transaction system 100 may target a movie / music-related product such as music or movie playback media or download data thereof, or other various products.

  In this case, the server device 1 may associate a product with a different type (that is, category) with the privilege granting condition DB 132 as a target product ID and a related product ID as a privilege target. For example, the server device 1 registers a book and a media for reproducing the content in which the book is turned into a movie as a related product in the privilege granting condition DB 132, and when one of the books has been purchased, You may apply the privilege based on purchase history. Similarly, the server device 1 registers the movie playback media and the movie soundtrack album playback media as related products in the privilege granting condition DB 132, and when either one has been purchased, You may apply the privilege based on a purchase history with respect to the other.

(Modification 7)
The server device 1 may be composed of a plurality of servers. For example, the server device 1 may be composed of a server having the product information DB 131, a server having the privilege granting condition DB 132, a server having the purchase history DB 133, and a server that executes the processes of FIGS. In this case, the server that executes the processes of FIGS. 5 and 6 functions as a “transaction apparatus” in the present invention, and exchanges information necessary for the allocated process with other servers via the communication network 2. .
