Abstract

Terminal devices of a plurality of users and a server apparatus are connected via a communication network. First search step performed by the server apparatus searches a database, on the basis of information about a particular user, for one or more other users. For example, the first search step specifies at least one artist (e.g., favorite artist) or work from the database, and then searches the database for one or more other users using the specified artist or work as an augment. Second search searches the database for one or more artists (e.g., favorite artist) or works, using, as augments, the one or more other users searched out from the database. Then, the thus searched-out favorite artists or works of the other users are presented to the particular user.

Claims

1. An information search method for use in a system including a database storing pieces of information about a plurality of users and artists and/or works registered in association with the plurality of users, said information search method comprising:

a first search step of, on the basis of information about a particular user, searching said database for one or more other users;

a second search step of searching said database for one or more artists or works, using, as augments, the one or more other users searched out from said database by said first search step; and

a step of presenting, to the particular user, a search result based on the one or more artists or works searched out from said database by said second search step.

2. An information search method as claimed in claim 1 wherein said first search step includes a step of specifying at least one artist or work in relation to the particular user, and a step of searching said database for the one or more other users using the specified at least one artist or work as an augment.

3. An information search method as claimed in claim 1 wherein said step of presenting includes a step of extracting, in accordance with a predetermined extraction criterion, at least one recommendable artist or recommendable work from among the one or more artists or works searched out from said database by said second search step, and said step of presenting presents the extracted recommendable artist or recommendable work to the particular user.

4. An information search method as claimed in claim 3 wherein the predetermined extraction criterion is based on a predetermined statistical algorithm.

5. An information search method as claimed in claim 4 wherein the predetermined statistical algorithm is designed to select, as the at least one recommendable artist or recommendable work, an artist or work having been designated most frequently by the one or more other users.

6. An information search method as claimed in claim 3 wherein, when said step of extracting could not extract any recommendable artist or recommendable work from among the one or more artists or works searched out from said database, said step of presenting a predetermined recommendable artist or recommendable work to the particular user.

7. An information search method as claimed in claim 2 wherein said step of specifying selects and specifies the at least one artist or work from among artists or works registered in said database in relation to the particular user.

8. An information search method as claimed in claim 2 wherein said step of specifying specifies the at least one artist or work in response to selection operation by the particular user.

9. An information search method as claimed in claim 1 wherein said second search step not only searches said database for one or more artists using, as augments, the one or more other users searched out from said database by said first step, and but also searches said database for works in which the one or more artists searched out from said database took part, and

wherein said step of presenting presents, to the particular user, both the one or more artists searched out from said database and the works in which the searched-out artists took part, as the search result.

10. An information search method as claimed in claim 1 wherein said first search step searches said database for one or more other users having a commonality in personal characteristic with the particular user.

11. An information search method as claimed in claim 2 wherein said first search step further includes a step of, when said first search step could not search out the one or more other users from said database using, as augments, the specified artist or work, searching said database for one or more other users having a commonality in personal characteristic with the particular user.

12. An information search method as claimed in claim 1 wherein said system is a system that sells or lends content of the works to the users or allows the users to use the content of the works.

13. An information search method as claimed in claim 12 wherein the works are music pieces, karaoke music pieces, movies, novels, comics, or cartoon films.

14. An information search method as claimed in claim 1 which is performed by a computer of a server connected to terminal devices of the plurality of users via a communication network.

15. An information search method as claimed in claim 14 wherein said step of presenting includes a step of transmitting the search result to the terminal device of the particular user via the communication network.

16. A program containing a group of instructions to cause a computer to perform the information search method of claim 1.

17. A machine-readable storage medium containing the program of claim 16.

18. An information search apparatus for use in a system including a database storing pieces of information about a plurality of users and artists and/or works registered in association with the plurality of users, said information search apparatus comprising a processor coupled with said database, said processor being adapted to:

search said database for one or more other users on the basis of information about a particular user;

search said database for one or more artists or works, using, as augments, the one or more other users searched out from said database; and

present, to the particular user, a search result based on the one or more artists or works searched out from said database.

19. An information search apparatus as claimed in claim 18 which is provided in a server connected to terminal devices of the plurality of users via a communication network.

20. An information search apparatus as claimed in claim 19 wherein the search result is presented to the particular user by said processor transmitting the search result to the terminal device of the particular user via the communication network in response to a request from the particular user.
