a sixth information corresponding to the third terminal to a fourth terminal of the second waiting user.

3. The method of claim 1 , wherein the at least two lists include a second list that is different from the first list;

at least one waiting user included in the second list is associated with a second value of the specific feature; and

after the adding of the user of the first terminal to the first list, the method further comprises adding the user of the first terminal to the second list when the user of the first terminal is not matched until a specific time has elapsed.

4. The method of claim 1 , wherein the first list corresponds to a first value of the specific feature; and

at least one waiting user included in the first list is associated with the first value.

5. The method of claim 4 , wherein the at least two lists include a second list that is different from the first list;

at least one waiting user included in the second list is associated with a second value of the specific feature; and

the method further comprises:

when it is determined that the first waiting user is not present in the first list, determining whether the first waiting user is present in the second list using the first information; and

when it is determined that the first waiting user is present in the second list, facilitating matching between the user of the first terminal and the first waiting user for online conversations by transmitting at least one selected from the group consisting of:

the second information corresponding to the first waiting user in the second list to the first terminal; and

the third information corresponding to the first terminal to the second terminal of the first waiting user.

6. The method of claim 5 , wherein the first value and the second value have an inclusion relation.

7. The method of claim 5 , further comprising, when it is determined that the first waiting user is not present in the second list, adding the user of the first terminal to the first list or the second list.

8. The method of claim 1 , wherein the first information comprises at least one of location information of the first terminal, and location information, gender information, age information, job information, interest information, ethnicity information, religion information, command-of-language information, or favorite partner condition information of the user of the first terminal.

9. The method of claim 8 , wherein the favorite partner condition information of the user of the first terminal comprises at least one of location information, gender information, age information, job information, interest information, ethnicity information, religion information, command-of-language information, and favorite partner condition information of a partner whom the user of the first terminal wants to match.

10. The method of claim 1 , further comprising:

determining whether the first waiting user matching the user of the first terminal based on the first information is present in the first list;

calculating correspondences between the user of the first terminal and waiting users included in the first list using the first information;

determining whether a correspondence having a threshold value or more is present in the calculated correspondences; and

determining whether the first waiting user is present in the first list based on the calculated correspondences.

11. The method of claim 10 , wherein

each of the at least one waiting user includes information about the waiting user; and

the calculating of the correspondences comprises:

selecting a specific waiting user from among the at least one waiting user included in the first list;

selecting at least one first factor from among factors included in the first information;

calculating correspondence scores of the at least one first factor by comparing the at least one first factor with a second factor corresponding to the at least one first factor among factors included in information about the waiting user; and

calculating a correspondence between the user of the first terminal and the specific waiting user by calculating a weighted sum of the calculated correspondence scores.

12. The method of claim 1 , wherein the specific feature comprises location, gender, age, job, interest, ethnicity, religion, language, favorite partner condition, or a combination thereof.

13. A non-transitory computer-readable recording medium storing a program for executing the method of claim 1 .

14. A system for matching users for online conversations comprising:

a device, comprising a processor, for matching users for online conversations; and

at least two terminals connected to the device;

wherein the device:

stores at least two lists that respectively correspond to different values of a specific feature and that each of which includes at least one waiting user;

receives first information about a first terminal or a user of the first terminal among the at least two terminals;

derives a value for the specific feature using the received first information;

selects a first list from among the at least two lists using the derived value;

determines whether a first waiting user matching the user of the first terminal based on the first information is present in the first list;

when it is determined that the first waiting user is not present in the first list, adds the user of the first terminal to the first list; and

when it is determined that the first waiting user is present in the first list, removes the first waiting user from the first list and facilitates matching between the user of the first terminal and the first waiting user for online conversations by transmitting at least one of:

a second information corresponding to the first waiting user to the first terminal; and

a third information corresponding to the first terminal to a second terminal of the first waiting user.

15. A device for matching users for online conversations comprising:

a set of one or more processors communicatively coupled to a memory, an input interface, and an output interface;

the memory readable by the set of processors; and

instructions stored in the memory that when read by the set of processors direct the set of processors to perform operations, the operations including:

preparing at least two lists that respectively correspond to different values of a specific feature and that each of which includes at least one waiting user;

receiving a first information from a first terminal about at least one of:

the first terminal; and

a user of the first terminal;
