Method of recommending friends, and server and terminal therefor

Abstract

A method of recommending a friend in a first terminal is provided. The method includes generating first interest keyword information by analyzing event information of the first terminal, receiving second interest keyword information of a second terminal, comparing the first interest keyword information and the second interest keyword information, and displaying information recommending a user of the second terminal as a friend based on a result of the comparing.

         2 . The method of  claim 1 , wherein the determined friend recommendation information includes a plurality of friend recommendation information arranged in an order determined according to the obtained similarity. 
     
     
         3 . The method of  claim 1 , further comprising:
 receiving, by the processor from a terminal, at least one friend information selected based on the provided friend recommendation information; and   based on the receiving the selected at least one friend information, forming, by the processor, a user of the terminal and at least one user corresponding to the selected at least one friend information into a group.   
     
     
         4 . The method of  claim 3  further comprising:
 receiving, by the processor, content based on a content sharing operation from at least one of the user of the terminal and the at least one user; and 
 transmitting, by the processor, the content to remaining terminals except for a terminal of a user who has transmitted the content among the plurality of users included in the group so that the received content is shared by the plurality of users included in the group. 
 
     
     
         5 . The method of  claim 1 , wherein the method of recommending the friend is performed by using a virtual interest keyword collection space generated in the server,
 further comprising:   deleting, by the processor, information stored in the virtual interest keyword collection space when a predetermined time has passed.   
     
     
         6 . The method of  claim 5 , wherein the predetermined time is determined according to the at least one from among the location information and the time information. 
     
     
         7 . The method of  claim 1 , wherein the interest keyword information includes a keyword generated by generalizing at least one keyword obtained from each of the plurality of terminals using the at least one of the location information and the time information. 
     
     
         8 . A server for recommending a friend, the server comprising:
 a communication interface;   a storage storing a program; and   a processor which is configured to:   by executing the program,   receive, through the communication interface, interest keyword information from each of a plurality of terminals connected to the server through the communication interface, wherein the interest keyword information includes at least one from among location information and time information corresponding to the interest keyword information,   store the received interest keyword information into the storage,   obtain a similarity between the interest keyword information received from each of the plurality of terminals,   determine friend recommendation information on each terminal included in the plurality of terminals according to the obtained similarity, and   provide the determined friend recommendation information to the each terminal included in the plurality of terminals through the communication interface.   
     
     
         9 . The server of  claim 8 , wherein the determined friend recommendation information includes a plurality of friend recommendation information arranged in an order determined according to the obtained similarity. 
     
     
         10 . The server of  claim 8 , wherein the processor is configured to:
 receive, through the communication interface from a terminal, at least one friend information selected based on the provided friend recommendation information; and   based on the receiving the selected at least one friend information, form a user of the terminal and at least one user corresponding to the selected at least friend information into a group.   
     
     
         11 . The server of  claim 10 , wherein the processor is configured to:
 receive, through the communication interface, content based on content sharing operation from at least one of the user of the terminal and the at least one user; and   transmitting, through the communication interface, the content to remaining terminals except for a terminal of a user who has transmitted the content among the plurality of users included in the group so that the received content is shared by the plurality of users included in the group.   
     
     
         12 . The server of  claim 8 , wherein the processor is further configured to:
 perform an operation of recommending the friend by using a virtual interest keyword collection space generated in the storage, and   delete information stored in the virtual interest keyword collection space when a predetermined time has passed.   
     
     
         13 . The apparatus of  claim 12 , wherein the predetermined time is determined according to the at least one from among the location information and the time information. 
     
     
         14 . The apparatus of  claim 8 , wherein the interest keyword information includes a keyword generated by generalizing at least one keyword obtained from each of the plurality of terminals using the at least one of the location information and the time information. 
     
     
         15 . A computer program product comprising one or more computer-readable recording media having a computer readable program stored therein, wherein the computer readable program, when executed on a computer device, causes the computing device to perform a method of recommending a friend, wherein the method comprises:
 receiving interest keyword information from each of a plurality of terminals connected to the server, wherein the interest keyword information includes at least one from among location information and time information corresponding to the interest keyword information;   obtaining a similarity between the interest keyword information received from each of the plurality of terminals;   determining friend recommendation information on each terminal included in the plurality of terminals according to the obtained similarity; and   providing the determined friend recommendation information to the each terminal included in the plurality of terminals.   
     
     
         16 . The computer program product of  claim 15 , wherein the determined friend recommendation information includes a plurality of friend recommendation information arranged in an order determined according to the obtained similarity. 
     
     
         17 . The computer program product of  claim 15 , wherein the method further comprises:
 receiving, from a terminal, at least one friend information selected based on the provided friend recommendation information; and   based on the receiving the selected at least one friend information, forming a user of the terminal and at least one user corresponding to the selected at least friend information into a group.   
     
     
         18 . The computer program product of  claim 17 , wherein the method further comprises:
 receiving content based on content sharing operation from at least one of the user of the terminal and the at least one user; and   transmitting the content to remaining terminals except for a terminal of a user who has transmitted the content among the plurality of users included in the group so that the received content is shared by the plurality of users included in the group.   
     
     
         19 . The computer program product of  claim 15 , wherein the method of recommending the friend is performed by using a virtual interest keyword collection space generated in the server,
