Method and apparatus for recommending information using a hybrid algorithm

A method of receiving a recommendation of information, the method comprising:

• requesting a server to recommend information on at least one item among items of the server;
• receiving first item information at a client on items preferred by clients of a neighborhood group, the neighborhood group selected based on first preference information which represents an item preference of the client from the server;
• and
• generating second item information on items to be recommended to a user by filtering the received first item information based on second preference information which represents an item preference of the client,
• wherein the neighborhood group is a group of clients having preferences similar to a preference corresponding to the first preference information.

A server device for recommending information, the server device comprising:

• a request receiving unit receiving a request from a client for recommending information on at least one item among items of the server;
• a preference generation unit generating first preference information by analyzing an item preference of the client;
• a group selection unit selecting a neighborhood group including clients having preferences similar to a preference of the client;
• and
• an information generation unit transmitting first item information on at least one item preferred by the clients of the neighborhood group to the client,
• wherein the client receives the first item information and extracts second item information to be recommended for a user by filtering the first item information with second preference information which represents an item preference of the client.

A client device for receiving a recommendation of information, the client device comprising:

• a request transmission unit requesting a server to recommend information on at least one item among items of the server;
• an information receiving unit receiving first item information on items preferred by clients of a neighborhood group, the neighborhood group selected based on first preference information which represents an item preference of the client;
• a preference generation unit generating second preference information which represents an item preference of the client;
• and
• an information generation unit generating second item information on items to be recommended for a user by filtering the received first item information with the second preference information,
• wherein the neighborhood group is a group of clients having preferences similar to a preference corresponding to the first preference information.

A method of recommending information, the method comprising:

• generating first recommendation information by allowing a server to filter information with a first information filtering algorithm;
• generating second recommendation information by allowing a client to filter the first recommendation information with a second information filtering algorithm;
• and
• displaying the second recommendation information to a user.

A computer program product for recommending information, the computer program product embodied on a computer readable medium and when executed by a computer system, performs the method comprising:

• receiving a request from a client for recommending information on at least one item among items of the server;
• generating first preference information by analyzing an item preference of the client;
• selecting a neighborhood group including clients having preferences similar to a preference of the client;
• and
• transmitting first item information to the client on at least one item preferred by the clients of the neighborhood group,
• wherein the client receives the first item information and extracts second item information to be recommended to a user by filtering the first item information with second preference information which represents an item preference of the client.
