To do. In addition, it is assumed that the user whose user ID is “07ab” has purchased a hay fever medicine in the past at the site B, and has newly purchased the grapefruit juice at the site A this time.

  In addition, FIG. 2 shows a case where a user using the same user identifier (user ID) “07ab” at the site A and the site B receives the service of the information providing system 1. Even when different user IDs are used for A and Site B, the service of the information providing system 1 can be received.

  Specifically, the user ID (for example, “aaa”) at the site A and the user ID (for example, “bbb”) at the site B are registered in the information providing system 1 and the user for the information providing system 1 is registered. ID (for example, “111”) is registered. The information providing system 1 has a user ID “111”, a site A user ID “aaa”, and a site B user ID “bbb”. It may be converted. Further, even when different login passwords are assigned to the respective user IDs, the same conversion method can be used.

  As shown in the figure, the information providing system 1 collects purchase history information from each site (site A and site B shown in the figure), and generates aggregated information for each user, that is, for each user ID. (See (1) in the figure). Here, this aggregated information includes the site from which purchase history information has been acquired and the collected purchase history information.

  On site A, a user whose user ID is “07ab” has purchase history information indicating that he / she purchased grapefruit juice on January 14, 2008. The user who is “07ab” has purchase history information indicating that he / she purchased a hay fever medicine on December 26, 2007.

  In this case, the information providing system 1 collects purchase history information with the user ID “07ab” from each site for the user with the user ID “07ab”, and displays the “aggregated information (user ID)” shown in FIG. : 07ab) ". Note that aggregate information is generated in the same manner for users corresponding to other user IDs. As described above, the information providing system 1 aggregates purchase history information scattered in a large number of shopping sites for each user, and therefore provides various services to the user using the aggregated information.
