PROBLEM TO BE SOLVED: To introduce items in which a small number of clients are commonly interested.;SOLUTION: Item identifiers whose number of clients are not present between the upper limit value and lower limit value of the number of client accesses of analysis origin items are deleted, and the list of client identifiers accessing the remaining item identifiers is extracted as a relevant client group from an access history map. The relevant client group is narrowed down, and the list of the item identifiers accessed by each client of the narrowed relevant client group extracted as a relevant item group from the access history map. The relevant item group is narrowed down, and the number of clients of each item identifier of the narrowed relevant item group is obtained from the access history map, and the item identifiers whose number of client accesses is not present between the upper limit value and lower limit value of the number of clients of the relevant items are deleted, and the remaining item identifiers are transmitted to a provider server as a correlation item detection response.;COPYRIGHT: (C)2002,JPO
