Similarly, an information requested database is added to a URL as URL information and published on a communications circuit network. Using a computer connected to the communications circuit network, the information about each item of the information providing database is sequentially compared with the information about each item of the information requested database from an item of the highest priority in the narrowest and lowest concept gradually to an item of a lower priority in a broader and upper concept until a matching combination can be detected. When a matching combination is detected, the information that a matching combination has been detected is displayed on the home pages of an information provider and an information requester, and the home page of the partner is directly displayed. Additionally, in the second invention, the information providing database and the information requested database are separately designed in advance, and a retrieval identifier is set.
