It is. In the present embodiment, the purchaser-specific demand information generation unit 104 generates purchaser-specific demand information (an example of product demand information) based on purchase history information and user family structure information. A specific example of the demand information generation process will be described.

  First, processing for generating purchaser-specific demand information based on purchase history information will be described. The purchaser-specific demand information generation unit 104 extracts a record having a common user ID from the purchase history information table stored in the purchase history information storage unit 102, and selects a record having common product information from the extracted records. Select and calculate the purchase date period (purchase period) in the selected record. The purchase cycle may be an average value of time intervals of purchase days, or may be a statistical value such as, for example, obtaining the purchase frequency for each day of the week and using the most frequent mode value. The purchaser-specific demand information generation unit 104 generates the purchaser-specific demand information with the latest purchase date of the product as the start date and the time when the purchase period of the product passes as the prediction date. In the purchase history information table, when the number of records having the same product information in the records having the same user ID is greater than or equal to a threshold, demand information for each purchaser for the product information may be generated.

  Next, processing for generating purchaser-specific demand information based on the user's family structure information will be described. The demand information generating unit 104 for each purchaser acquires the family configuration information of the target user from the user information storage unit 103, calculates the consumption amount for each product in a predetermined period of the family indicated in the family configuration information, and calculates the calculated amount. The consumption period for each product is calculated based on the consumption for each product. Specifically, the purchaser-specific demand information generation unit 104 uses the attribute information of each member indicated in the family structure information acquired for the target user as a key to calculate the daily consumption amount of the selected product as consumption information. Acquire from the table and total the acquired consumption. Next, the purchaser-specific demand information generation unit 104 calculates the consumption period of the product by dividing the capacity determined for the selected product by the total daily consumption. The demand information generating unit 104 for each purchaser acquires the latest purchase date of the selected product with reference to the purchase history information table, and the elapsed time of the calculated consumption period starting from the acquired latest purchase date Is obtained as the next purchase prediction date of the product. Note that the method for generating purchaser-specific demand information by the purchaser-specific demand information generation unit 104 is not limited to the above-described example, and may be generated based on a bid history of an auction by a user, an information browsing history, or the like. .

  FIG. 7 shows an example of a demand information table for each purchaser that stores the demand information for each purchaser generated by the demand information generation unit 104 for each purchaser. As illustrated in FIG. 7, the purchaser-specific demand information table stores a user ID, product information, and a prediction date in association with each other.

  The auction information presentation unit 106 uses the demand information for each purchase generated by the demand information generation unit 104 for each purchaser, and the product recommendation right for providing recommended information of the product to the user indicated in the demand information for each purchaser Information (auction information) related to the auction is presented to the store.

  The successful bidder determination unit 110 determines the successful bidder (store) of the product recommendation right related to the auction information presented by the auction information presentation unit 106 based on the bid information acquired by the bid information acquisition unit 108. The above-mentioned product recommendation right is given to the successful bidder who has made a successful bid. For example, the successful bidder determination unit 110 may determine the number of successful bidders determined by the auction conditions of the auction information in descending order of the bid amount included in the bid information acquired by the bid information acquisition unit 108. The bidder whose bid amount included in the bid information exceeds the amount determined in the auction conditions of the auction information may be determined as the successful bidder. Furthermore, in addition to the bid information acquired by the bid information acquisition unit 108, the successful bidder determination unit 110 includes at least one of evaluation information related to a product provided by a store that is a bidder of the bid information and a selling price of the product. It is good also as determining a successful bidder based on. In this case, for example, the evaluation value according to the bid amount, the evaluation value according to the evaluation information (for example, the sum of evaluation points for each review), and the evaluation value according to the sales price (for example, the lower the sales price is, It is good also as determining a successful bidder in order with a big sum total with high evaluation.

  The recommended product information acquisition unit 112 acquires information on a product recommended to the user based on the product recommendation right related to the auction information for which a successful bid is made. The recommended product information acquisition unit 112 may acquire product information recommended by accepting input of product information recommended by the store from the store terminal 30 of the store determined as the successful bidder. Based on the product information shown in the purchaser-specific demand information related to the successful product recommendation right and the store ID of the store, the corresponding product information is searched from the product information table stored in the product information storage unit 100. It is good also as acquiring.

  The recommended information providing unit 114 provides the recommended product information acquisition unit 112 to the user indicated in the demand information by purchaser related to the product recommendation right for which the store has made a successful bid at a time according to the prediction date indicated in the demand information by purchaser. The recommendation information that recommends the information of the product acquired in is provided. Here, the time according to the prediction date may be a predetermined period including the prediction date, or may be a predetermined period before the prediction date. The recommended information providing unit 114 may provide the recommended information to the user by displaying the recommended information on the dedicated page of the user, or the user by sending an e-mail including the recommended information to the e-mail address of the user. Recommended information may be provided. In addition, when there are a plurality of successful bidders for product recommendation rights, the recommended information providing unit 114 may provide recommended information to the user in descending order of the bid amount of each successful bidder.
