  The category relation structure T3 stores the product ID associated with the tag that refers to the leaf node in association with the leaf node. That is, a list of products associated with the category indicated by the leaf node can be acquired from the leaf node of the tree structure. By this reference, it is possible to acquire a list of products corresponding to the category and higher-level categories, that is, the ancestor nodes of the tree structure.

  FIG. 6 is a diagram showing an example of such an entry in the category table T2. This product having the product ID “ID20099092401” has three tags “A1”, “B4”, and “C13”, and the reference to the relationship structure of the category by these information is indicated by a solid line arrow. . These tags are references to the leaf nodes of the tree structure that manage the category, and point to the categories “language-English”, “humanities-linguistics”, and “learning reference book-high school-English”, respectively. On the other hand, the leaf node side of the tree structure that manages the category has a product ID “ID20099092411” as a reference to the product belonging to the corresponding category, and is indicated by a dashed arrow. However, in FIG. 6, reference to products other than the product whose product ID is “ID20099092411” is omitted. Actually, the leaf nodes “A1”, “B4”, and “C13” also hold references to other products belonging to the same category.

  FIG. 7 is a flowchart for explaining gift certificate purchase processing. FIG. 8 is a diagram illustrating an example of a screen displayed on the user terminal device 101 used by the gift certificate purchaser during the gift certificate purchase process. Unless otherwise specified, numbers beginning with S enclosed in parentheses “(” and “)” indicate corresponding steps in the figure. Before entering the flowchart of FIG. 7, when the gift certificate purchaser logs in to the electronic merchandise sales system 200 using the user terminal device 101 and performs an operation to instruct the start of the gift certificate purchase process, the user terminal device 101 and An instruction to start gift certificate purchase processing is input to the electronic merchandise sales system 200 via the network 100. When the communication processing unit 207 receives an instruction to start the gift certificate purchase process and outputs the instruction to the conditional expression generation unit 202, the conditional expression generation unit 202 starts the gift certificate purchase process.

  First, the conditional expression generation unit 202 causes the user terminal device 101 to display a screen that allows the gift certificate purchaser to select a condition to be set for the gift certificate, and acquires the condition to be set for the gift certificate (S701). In FIG. 8, the screen G81 is a screen that causes the gift certificate purchaser to select a condition to be set for the gift certificate. On the screen G81, for example, a product category list C81 for two layers from the top is displayed. The gift certificate purchaser selects a check box of a category that can be purchased with a gift certificate from the list C81, and decides this with the decision button B81. As shown in FIG. 8, when the check boxes of the categories “French” and “Learning reference book” are selected, when the determination button B81 is pressed, the user terminal device 101 displays information indicating these selected categories. (For example, the tag in FIG. 5) is transmitted to the electronic merchandise sales system 200 via the Internet 100. The communication processing unit 207 of the electronic merchandise sales system 200 receives this transmitted information and outputs it to the conditional expression generation unit 202 as a condition to be set for the gift certificate.

  Upon receiving the condition set on the gift certificate (information indicating the selected category), the conditional expression generation unit 202 causes the user terminal device 101 to display a screen for confirming the content of the condition set on the gift certificate, and the product Confirmation by the ticket purchaser is acquired (S702). In FIG. 8, a screen G82 displaying the selected categories “French” and “Learning reference book” is a screen for confirming the contents of the conditions set for the gift certificate. When acquiring the confirmation by the gift certificate purchaser, the conditional expression generation unit 202 generates a conditional expression to be set for the gift certificate based on the conditions set for the previously acquired gift certificate. For example, if the conditions set for the gift certificate acquired earlier are the categories “French” and “Learning reference book” as shown in the screen G82 in FIG. 8, and these tags are “A3” and “C”. The conditional expression generation unit 2020 concatenates these tags with “||” indicating a logical sum (OR), generates a conditional expression “A3 || C”, and outputs it to the gift certificate issuing unit 204.

  Upon receiving the conditional expression from the conditional expression generation unit 202, the gift certificate issuing unit 204 displays a screen for selecting or inputting a partner to which the gift certificate is given on the user terminal device 101, and acquires the gift certificate recipient ( S703). FIG. 8 shows an example in which user management in the user information storage unit 209 is performed based on a mail address and a gift certificate is sent by mail. A screen G83 is a screen for selecting or inputting a partner to whom the gift certificate is given. On the screen G83, the users (“Taro-san”, “Hanako-san”) who have been designated as gift recipients in the past and stored in association with the gift certificate purchaser in the user information recording unit 209 are the recipients (send destinations). Are displayed in the selection candidate list C83. Further, an input box A83 for inputting the mail address of the user for designating a new recipient is displayed on the screen G83. The gift certificate purchaser selects a user of the selection candidate list C83 or designates a gift certificate recipient by entering an e-mail address in the input box A83, and presses the decision button B83. Determine this.

  When the gift recipient is specified, the gift certificate issuing unit 204 causes the user terminal device 101 to display a screen for final confirmation of the gift certificate purchase for the gift certificate purchaser (S704). In FIG. 8, G84 is an example of the screen. Since the conditions set for the gift certificate are once confirmed on the screen G82, they are not displayed here again, but may be displayed on the screen G84. When the determination button B84 is pressed and the contents of the gift certificate to be purchased are determined, the gift certificate issuing unit 204 performs a settlement process for the purchased gift certificate price (S705). There are various payment methods for gift certificates depending on the payment method. For example, when making a payment with a credit card, an input of a card number or a personal identification number may be requested. When using electronic money operated in the electronic merchandise sales system 200, necessary electronic money and balance are calculated. You may ask for confirmation. Further, when the gift certificate purchaser inputs information necessary for the settlement process, it may be displayed and input before the final confirmation screen G84 for gift certificate purchase, and presented at the same time.

When the settlement is completed, the gift certificate issuing unit 204 actually generates electronic gift certificate data and issues a gift certificate (S706). The gift certificate includes information indicating the conditional expression generated in step S701. The conditional expression only needs to indicate a logical relationship between events, and for example, there is a condition described in a category (classification information) using a Boolean logic operator. The data format may be anything. For example, if a text representation is used, the condition specified on the screen G81 is “A3 || C” as described above. Here, “||” represents the OR of the logical expression. Similarly, if a logical expression using “&&” expressing AND and “¬” of negative, “(”, “)” expressing priority, etc., a more flexible expression is possible. In this embodiment, an event (here, a category) is uniquely described by using a tag name. However, an ambiguous notation such as a category name using a regular expression or the like may be used.
Next, the gift certificate issuing unit 204 delivers the issued gift certificate to the user selected in step S703 (S707). As described above, here, delivery is performed by e-mail, but the delivery method and medium are not particularly limited, such as e-mail or a paper medium on which a two-dimensional barcode is printed, and can be read electronically. Anything is acceptable.

  In the example shown on the screen G81 in FIG. 8, only the two-tier categories from the top are displayed to select the conditions set for the gift certificate. However, the gift certificate purchaser may want to specify a more detailed category. FIG. 9 is a diagram showing an example of a screen for specifying the category of the gift certificate in more detail for such a case. The screens G91, G92, and G93 displayed by the condition generation unit 202 show that the purchaser of the gift certificate selects detailed categories one by one and specifies the category to be selected as the condition.

  However, in the screens G91 to G94 displayed by the condition generation unit 202, a “confirm and continue” button B91 for confirming one category and specifying the next category is shown. When the purchaser of the gift certificate presses this button, the condition generating unit 202 repeats the procedures such as the screens G91, G92, and G93 a plurality of times to determine a plurality of categories. Screen G94 is an example of a screen displayed by condition generation unit 202 when the second category “travel-travel conversation-English” is selected in this way. The screen G94 displays a list A94b of categories that have been determined so far by pressing the “Confirm and Next” button B91, together with the hierarchy A94a of the currently selected category.

  When the “confirm” button B94 is pressed after selecting a plurality of categories in this way, the condition generating unit 202 displays a list C95 of a plurality of categories selected so far, as shown in the screen G95. The purchaser of the gift certificate can select which of the presented list C95 is permitted and which is not permitted. When the “OK” button B95 is pressed after selection, the condition generation unit 202 displays a screen G96 for displaying the result of the specified condition and final confirmation of the condition. In the example of FIG. 9, products belonging to the categories “Business-Self-development-Language” and “Language-English” checked by the purchaser of the gift certificate on the screen G95 can be purchased. Conditions are set so that products belonging to “travel-travel conversation-English” cannot be purchased. Even in such flexible condition setting, as described above, the condition generation unit 202 can generate a conditional expression expressing this using data using a text format and include it in the gift certificate. For example, if the tags indicating the categories “business-self-development-language”, “language-English”, and “travel-travel conversation-English” are “D22”, “A1”, and “E22”, respectively, FIG. In the example, the conditional expression generated by the condition generation unit 202 is “(D22 || A1) && ¬E22”.

In FIG. 9, the example which sets a flexible condition to a gift certificate using the combination of a some category was shown. However, the gift certificate purchaser does not know all the configurations of the categories managed by the electronic merchandise sales site 200. In such a case, purchase of an unintended product may be permitted. FIG. 10 is a diagram showing an example of a screen that enables the setting of a condition suitable for the intention of the gift certificate purchaser by automatically displaying the category that the gift certificate purchaser should pay attention to.
The screen G100 in FIG. 10 is displayed by the condition generation unit 202 in a state where the gift certificate purchaser follows the subcategory based on the category tree structure TR101 and selects the category “Language-English-Business English”. It is an example of a screen. That is, the product classifications that the gift certificate buyer purchases are the category CT100a “language”, the category CT100b “English” selected next, and the category CT101 “business English” to be selected.

  Here, a plurality of tree structures for managing categories may have nodes having the same name or similar names. In the example of FIG. 10, the name “language” matches the category CT102 in the node of the tree structure TR102, and the name “English” matches the category CT103 in the leaf node of the tree structure TR103. . Therefore, in order to present information related to the category (product classification) to which the gift certificate purchaser pays attention, the condition generation unit 202 searches for another category in the other tree structure. Here, in the tree structure TR102, a category 1002a “language” matching the focused classification information is found, and a category 1003a “English” is found in the tree shown in 1003. The condition generation unit 202 searches for these using a reference between nodes having the same category name and a reference between nodes having similar category names stored in the category information storage unit 201 described in FIG.

  When such a node is found, the condition generation unit 202 traces the tree structure from the found node to the upper level so that the related category RC100a (business-self-development-language), RC100b (travel-travel conversation-English) The category name of the corresponding node, the category name of the root node of the tree structure to which the node belongs, and the category name of the node existing between them are displayed in order from the top. The purchaser of the gift certificate selects the check box displayed next to the related categories RC100a and RC100b, so that the related category can be added to the condition without a complicated procedure, or the corresponding product can be excluded from the condition. can do.

If the tags “Category-English”, “Business-Self-development-Language”, and “Travel-Travel Conversation-English” are “A2”, “D22”, and “E22”, respectively, the related category RC100a presented. When the RC 100b is not used, the conditional expression generated by the condition generation unit 202 is “A2”, whereas when the validity of the related category RC 100a is checked, “A2 && D22” is checked, and further, the invalidity of the related category RC 100b is checked. When it is done, “A2 && D22 && ¬E22” is generated.
By combining the category information thus selected in the same manner as in the screen G96 of FIG. 9, it is possible to set detailed conditions for the gift certificate.

  So far, the purchase process of gift certificates has been described. Next, processing for purchasing a product using a gift certificate will be described. When a product purchaser selects a product under the conditions set in the gift certificate, as with online shopping sites that are currently widely used, searching for products using keywords, etc. You may choose In the following example, an example of searching for a product by searching is shown.

A product is searched (S1103).

  First, the purchaseable product presentation unit 206 outputs the conditional expression set in the gift certificate to the compatible product list generation unit 205. The compatible product list generation unit 205 receives this conditional expression, generates a list of products satisfying the conditional expression from the product storage unit 203, and outputs the list to the purchaseable product presentation unit 206. For example, the compatible product list generation unit 205 refers to the category configuration storage unit 201, generates a list of leaf node categories that satisfy the conditional expression, and stores the products stored in the product storage unit 203 in association with those categories. By extracting, a list of products satisfying the conditional expression is generated. When the purchaseable product presentation unit 206 receives a list of products satisfying the conditional expression, the purchaseable product presentation unit 206 searches the list of products using the search formula input on the screen G123. The purchaseable product presentation unit 206 displays the search result on the user terminal device 102 as a product selection screen, for example, like a screen G124. Conventionally, since the selection condition intended by the product purchaser is the search expression, all the products that satisfy this are displayed, but in this embodiment, only the products that satisfy both the conditions set for the gift certificate are displayed. Display.

  When the merchandise purchaser selects a merchandise to be purchased from the displayed merchandise (S1104), the merchandise sales processing unit 208 receives this, performs merchandise sales processing, and ends the merchandise purchase processing.

The ISBN table T3 in FIG. 17 includes a product ID “ID20090909241” that is information for identifying a product at each site, and an ISBN number “ISBN978-4-0123-4567” that is information for identifying a product (book) in common to all sites. −8 ”is stored in association with each other. Note that since the product ID is assigned a different value for each site for the same product, the ISBN table also differs for each site.

If the site that sells the gift certificate and the site that sells the product are the same as in the first and second embodiments, the category information set in the gift certificate matches that of the product purchase site. When selling, it is easy to determine whether the product meets the conditions specified on the gift certificate. However, when the site for selling the gift certificate (electronic gift certificate sales site 500a ...) and the site for selling the product (electronic product sales site 400a ...) are different sites as in the present embodiment, normally This is not easy because the category information managed by the product storage unit does not match.
FIG. 18 is a flowchart for explaining the product purchase processing in such a case. In this flowchart, the electronic merchandise sales site 400a solves this problem by inquiring of the electronic merchandise certificate sales site 500a a list of products that satisfy the conditions specified in the gift certificate.

  When the product purchaser logs in to the electronic product sales site 400a via the user terminal device 102 and the product purchase process is started, the purchaseable product presentation unit 206b stores the data of the gift certificate designated by the product purchaser. The information is read from the gift certificate storage unit 211b of the electronic gift certificate sales site 500a, and the conditions set in the gift certificate are acquired (S1301). At this time, from which electronic gift certificate sales site the gift certificate data is read may be specified by the product purchaser, or the information identifying the electronic gift certificate sales site is included in the identification information of the gift certificate. It may be determined based on the information.

  The purchaseable product presentation unit 206b passes the conditions set for the gift certificate to the compatible product list generation unit 205 of the electronic gift certificate sales site 500a via the communication processing unit 207, and the ISBN number of the product that conforms to this condition. (S1302). Next, the purchaseable product presentation unit 206b satisfies a search condition such as a category specified by the product purchaser via the user terminal device 102, and obtains a list of ISBN numbers of products stored in the sales product storage unit 212b. Compared with the list acquired in step S1302. As a result of the comparison, the purchaseable product presentation unit 206b generates a list of products included in both lists, and displays the list on the user terminal device 102 as a list of products that can be purchased (S1303). At this time, the purchaseable product presentation unit 206b converts the ISBN number list into the product ID list using the ISBN table stored in the sales product storage unit 212b. Next, the purchaseable product presentation unit 206b causes the user terminal device 102 to display a list of products that can be purchased using information on each product stored in the sales product storage unit 212b in association with these product IDs. . The rest is the same as steps S1104 and S1105 in FIG.

In addition, you may perform as follows after step S1302. The purchaseable product presentation unit 206b communicates with the electronic gift certificate sales site 500a via the communication processing unit 207, passes the conditions set in the gift certificate, and requests a list of products that match this ( S1302).
The compatible product list generation unit 205b of the electronic gift certificate sales site 500a that has received this request via the communication processing unit 207 processes the specified category information and uses the product information stored in the product storage unit 203b. The corresponding product list is acquired and converted into a list of common IDs that can be identified by the electronic product sales site 400a that made the inquiry. In the present embodiment where the product is a book, the product is converted into a list of ISBN numbers. This is sent back to the requesting electronic merchandise sales site 400a via the communication processing unit 207. The list of products acquired in this way is called an acquired product list.

The purchaseable product presentation unit 206b converts the acquired product list into a product list that is converted into a list of products managed on its own site (S1304). This converted product list is referred to as a converted product list. Furthermore, the information of the category to which the converted product list belongs is generated. Information on this category is called a purchaseable category.
More specifically, the purchaseable product presentation unit 206b generates a converted product list that can be purchased at the electronic product sales site 400a using the acquired product list and the product information stored in the sales product storage unit 212b. To do.

Here, the information stored in the sales merchandise storage unit 212b includes a category name and its relationship, and a difference in the number and type of products, but the product storage unit 203b and the category configuration storage unit of the electronic gift certificate sales site 500a. It is assumed that the product information is the same as that stored in 201.
Therefore, the ISBN table shown in FIG. 17 is used for this conversion. In addition, the compatible product list generation unit 205b generates a purchaseable category list that can be purchased with the gift certificate using the converted product list and the category information stored in the category configuration storage unit 201.
When the conditions set in the gift certificate are converted into a converted list and a purchaseable category list that can be purchased at the electronic merchandise sales site 400a, a screen when the purchaser of the gift certificate selects a product category (FIG. 9). In the same manner as in), the product purchaser narrows down the desired product based on the category and selects the product (S1305).

  In the first to third embodiments described above, when displaying a purchaseable category or product on the user terminal device 102, only a purchaseable item such as a product included in the converted product list or the purchaseable category list is available. However, it is possible to purchase by displaying that all products and categories handled by the electronic merchandise sales site 400a are not displayed by displaying them in gray out except for valid ones. You may make it display a thing.

  In particular, it is normal that the assortment of goods is different between the electronic gift certificate sales site and the electronic product sales site. For example, in the case of a book, there may be a case where a revised version or translated version of a certain product is handled only at an electronic merchandise sales site. In such a case, since these products are not included in the acquisition list, they are not included in the converted list. However, since these products are related products that may attract the purchaser's interest, they may be displayed even if they cannot be purchased with the gift certificate. By doing so, it is possible to increase the possibility of purchasing at the expense of the product purchaser himself.

  In the first to third embodiments described above, a book is taken as an example of a product, and ISBN (International Standard Book Number) is used as product identification information commonly used between sites. However, in the case of a gift certificate for purchasing other products such as clothing and home appliances, other product identification information is used. For example, a barcode, Auto-ID, or the like can be used.

In general, businesses that issue gift certificates often have a settlement function. The business operator who operates the electronic merchandise sales site may pay the compensation for the settlement function by paying a part of the sales to the business operator who issues the gift certificate.
Or, if the business that issues the gift certificate is different from the business that operates the electronic gift certificate sales site, the business that issues the gift certificate will return the profit to the business operator that operates the electronic gift certificate sales site. You may pay a part.
As another example, one of the electronic gift certificate sales sites may be the same as one of the electronic product sales sites and the business operator that issues the gift certificates. In particular, when the price of an electronic gift certificate is purchased with electronic money managed and operated by such an operator, in addition to the payment function for the electronic money that the operator already has, a new payment method is provided. There is no need to prepare.

  Also, a program for realizing the functions of the respective units in FIGS. 2, 13, and 16 is recorded on a computer-readable recording medium, and the program recorded on the recording medium is read into a computer system and executed. You may process each part by. Here, the “computer system” includes an OS and hardware such as peripheral devices.

Further, the “computer system” includes a homepage providing environment (or display environment) if a WWW system is used.
The “computer-readable recording medium” refers to a storage device such as a flexible medium, a magneto-optical disk, a portable medium such as a ROM and a CD-ROM, and a hard disk incorporated in a computer system. Furthermore, the “computer-readable recording medium” dynamically holds a program for a short time like a communication line when transmitting a program via a network such as the Internet or a communication line such as a telephone line. In this case, a volatile memory in a computer system serving as a server or a client in that case, and a program that holds a program for a certain period of time are also included. The program may be a program for realizing a part of the functions described above, and may be a program capable of realizing the functions described above in combination with a program already recorded in a computer system.

  The embodiment of the present invention has been described in detail with reference to the drawings. However, the specific configuration is not limited to this embodiment, and includes design changes and the like within a scope not departing from the gist of the present invention.
