PROBLEM TO BE SOLVED: To prevent the deterioration of the accuracy of estimating a click rate.SOLUTION: A distribution server 10 calculates the feature amount of an image having a history of being selected by a user. In addition, the distribution server 10 generates a user estimation model 17 for estimating the attribute information of the user who has selected the image, from the feature amount of the image, on the basis of both the calculated feature amount and the attribute information indicating the attribute of the user who has selected the image. Thus, even when the attribute information of a user which is a distribution destination of an advertisement is unclear such as in a cold start state, the distribution server 10 can accurately estimate the attribute information of the user, thereby allowing the accuracy of estimating the click rate to be improved and allowing an advertisement as a distribution target to be appropriately selected.SELECTED DRAWING: Figure 1
