2. The method of claim 1, further comprising:

collecting the event information in the first terminal,

wherein the collecting of the event information comprises collecting at least one from among location information of the first terminal, network information, user status information, sent/received message information, phone call history information, social networking service (SNS) usage information, application usage information, web page usage information, and payment information.

3. The method of claim 2, wherein the generating the first interest keyword information comprises selecting at least one first interest keyword by analyzing the event information, and

wherein the first interest keyword information comprises the at least one first interest keyword and at least one from among first location information and first time information corresponding to the first interest keyword.

4. The method of claim 3, wherein the selecting the at least one first interest keyword comprises generalizing the event information into a higher level first interest keyword.

5. The method of claim 4, wherein the generalizing the event information comprises setting a generalization level for the generalizing the event information into a higher level first interest keyword.

6. The method of claim 3, wherein the selecting the at least one first interest keyword comprises:

extracting a plurality of candidate keywords by analyzing the event information; and

selecting the at least one first interest keyword from among the plurality of candidate keywords based on the number of times each of the plurality of candidate keywords is extracted.

7. The method of claim 1, wherein the receiving of the second interest keyword information comprises receiving second interest keyword information comprising a second interest keyword that is generalized as higher level information based on event information of the second terminal.

8. The method of claim 7, wherein the second interest keyword information further comprises at least one from among second location information and second time information mapped to the second interest keyword.

9. The method of claim 1, wherein the receiving of the second interest keyword information from the second terminal is performed through at least one from among a wireless local area network (LAN), a near field communication (NFC), Bluetooth, Zigbee, Wi-Fi Direct (WFD), and ultra wideband (WUB) communication.

10. The method of claim 1, wherein the displaying the information recommending a user of the second terminal as a friend comprises:

calculating a similarity between the first interest keyword information and the second interest keyword information based on the result of the comparing; and

displaying the information recommending the user of the second terminal as the friend if the similarity is a predetermined value or greater.

11. The method of claim 1, further comprising deleting the second interest keyword information after a predetermined time has passed.

12. The method of claim 1, further comprising:

receiving a command to perform a sharing operation for sharing content;

receiving a selection of a zone to perform the sharing operation; and

transmitting a friend request message including information about the sharing operation to the second terminal if the second interest keyword information indicates that the second terminal is located in the selected zone.

13. The method of claim 12, further comprising:

receiving a friend acceptance message from the second terminal in response to the transmitting the friend request message; and

sharing content with the second terminal in response to the receiving of the friend acceptance message.

14. The method of claim 13, wherein the sharing of the content comprises:

transmitting first content shared by the first terminal to the second terminal; and

receiving second content shared by the second terminal, from the second terminal.

15. A non-transitory computer-readable recording medium having embodied thereon a program for executing the friend recommending method of claim 1.

16. A first terminal for recommending a friend, the first terminal comprising:

a display;

a communication unit; and

a controller which is configured to control the communication unit to receive second interest keyword information of a second terminal, generate first interest keyword information by analyzing event information of the first terminal, compare the first interest keyword information and the second interest keyword information, and control the display to display information recommending a user of the second terminal as a friend based on a result of the comparing.

17. The first terminal of claim 16, wherein the controller is further configured to collect the event information in the first terminal, and

wherein the event information comprises at least one from among location information of the first terminal, network information, user status information, sent/received message information, phone call history information, social networking service (SNS) usage information, application usage information, web page usage information, and payment information.

18. The first terminal of claim 17, wherein the controller is further configured to analyze the event information to select at least one first interest keyword, and

wherein the first interest keyword information comprises the at least one first interest keyword and at least one from among first location information and first time information corresponding to the first interest keyword.

19. The first terminal of claim 18, wherein the controller is further configured to select the at least one first interest keyword by generalizing the event information into a higher level first interest keyword.

20. The first terminal of claim 19, wherein the controller is further configured to set a generalization level for the generalizing the event information into the higher level first interest keyword.

21. The first terminal of claim 18, wherein the controller is further configured to select the at least one first interest keyword by extracting a plurality of candidate keywords from the analyzed the event information, and select the at least one first interest keyword from among the plurality of candidate keywords based on the number of times each of the plurality of candidate keywords are extracted.

22. The first terminal of claim 16, wherein the controller is further configured to control the communication unit to receive second interest keyword information comprising a second interest keyword that is generalized as higher level information based on event information of the second terminal.

23. The first terminal of claim 22, wherein the second interest keyword information further comprises at least one from among second location information and second time information mapped to the second interest keyword.

24. The first terminal of claim 16, wherein the communication unit is configured to communicate with the second terminal through at least one from among a wireless local area network (LAN), a near field communication (NFC), Bluetooth, Zigbee, Wi-Fi Direct (WFD), and ultra wideband (WUB) communication.
