In addition, the recommendation unit 116 can suggest products to the user according to both the favorability rating and the purchase intention. FIG. 5 is a diagram for explaining the determination of products to be proposed according to both favorable ratings and purchase intentions.

As shown in the figure, the recommendation unit 116 proposes the same product as the product purchased by the user when the favorable impression is good (“like”) and the user intends to purchase again (“purchase again”). can be done. Also, even when the favorable impression is good (“like”), when there is no intention to purchase again (“never buy again”), the recommendation unit 116 proposes a product similar to or a substitute for the product purchased by the user. can do.

The recommendation unit 116 can also suggest the same product as the product purchased by the user when there is a repurchase intention (“purchase again”) even if the favorable impression is poor (“dislike”). You can also suggest similar or alternative products. In addition, the favorable impression is poor (“dislike”
), when there is no intention to purchase again (“Never buy again”), the recommendation unit 116
can suggest products that are similar to or substitute for the product purchased by the user.

In addition, the recommendation unit 116 can propose a similar product or a substitute product for each purpose when recommending products. For example, the recommendation unit 116 uses the product ID of the purchase data
It is possible to read the category for each purpose included in the product information corresponding to , and propose other products in the same category (middle class or small class) as the read category (middle class or small class).

Also, the recommendation unit 116 can estimate the purchase interval at which the user purchases products based on the purchase data. The recommendation unit 116 can propose a product to the user when a period corresponding to the estimated purchase interval has elapsed from the date of the latest purchase data corresponding to the user. For example, the recommendation unit 116 selects, from the purchase history storage unit 131, among the purchase data corresponding to the user ID and the product ID, the past predetermined period (the entire period may be used, or the past one year may be used. , may be a predetermined number in order of newest), arranging the extracted purchase data in order of purchase date, and summarizing the interval between the purchase dates of two consecutive purchase data (which may be an average value) However, it may be the median value or the expected value of the distribution estimated by Bayesian learning or the like.) can be estimated as the purchase interval. The recommendation unit 116 can recommend products on a date obtained by adding the estimated purchase interval to the date of the latest purchase data.

In addition, the recommendation unit 116, based on the purchase data, determines the number of times the product was purchased during a predetermined period (for example, one month, six months, one year, or any other arbitrary period) (purchase frequency).
is equal to or greater than a predetermined threshold, it is possible to propose the product even when the favorable impression of the product is low (“dislike”). In addition, when the favorable impression is poor, the recommendation unit 116 can propose products similar to the product in question (products in the same minor classification). again,
If the favorable impression is poor, the recommendation unit 116 recommends alternative products (products with the same middle classification) for the product in question.
can also be proposed. In addition, if the favorable impression is not good and there is an intention to purchase again ("want to buy again"), other products (similar products or alternative products) having the same purpose as the product concerned can be proposed.

In addition, the recommendation unit 116 detects information specifying a product (product name, etc.) and keywords related to the product (eg, “broken”, “unusable”, “lost”) from the e-mail data. As an opportunity, the product concerned, a similar product, or a substitute product can be proposed.

In addition, the recommendation unit 116 is triggered by the start of a campaign such as a discount by a product seller, and the user who has set a high favorable rating for the target product or the intention to purchase again for the target consumption (“want to buy again”). ) can be proposed to the target product.
