4. The electronic device of claim 1 , wherein the processor is further configured to:

identify a specific phrase from the user input;

identify a sub category of the identified category based on the specific phrase; and

identify the second response data from the sub category.

5. The electronic device of claim 1 , wherein the processor is further configured to:

provide third response data in response to not identifying the category corresponding to the identified emotion, and

wherein the third response data is included in a database separate from the main database and the auxiliary database.

6. The electronic device of claim 1 , wherein the processor is further configured to:

extract the first information from the user input based on natural language processing.

7. The electronic device of claim 1 , further comprising:

a speaker,

wherein the processor is further configured to convert the processing result, that is in a text form, into voice data to provide the voice data through the speaker.

8. A method for processing a user input of an electronic device comprising a main database including a plurality of input data and an auxiliary database including a plurality of categories, wherein each of the plurality of input data includes at least one first response data and wherein each of the plurality of categories includes at least one second response data, the method comprising:

receiving the user input, using a user interface;

extracting first information from the user input;

in response to identifying that input data matching the first information is identified among the plurality of input data, providing first response data corresponding to the input data matched the first information as a processing result for the user input; and

in response to identifying that the input data matching the first information is not identified among the plurality of input data,

identifying an emotion for a user based on at least a portion of the user input;

identifying a category corresponding to the identified emotion among the plurality of categories included in the auxiliary database;

identifying second response data corresponding to the identified category; and

providing the second response data as the processing result for the user input.

9. The method of claim 8 , further comprising:

determining a capsule or domain supporting a chatting mode using an utterance of a user, based in part on the user input.

10. The method of claim 8 , further comprising:

providing third response data in response to not identifying the category corresponding to the identified emotion,

wherein the third response data is included in a database separate from the main database and the auxiliary database.

11. The method of claim 8 , further comprising:

converting the processing result, that is in a text form, into voice data to provide an external electronic device with the voice data, using a communication module.

12. The method of claim 8 , further comprising:

identifying a specific phrase from the user input;

identifying a sub category of the identified category based on the specific phrase; and

identifying the second response data from the sub category.

13. The method of claim 8 , wherein the extracting of the first information from the user input includes:

extracting the first information from the user input based on natural language processing.

14. A system comprising:

a first electronic device including a communication module and a user interface; and

a second electronic device configured to communicate with the first electronic device through the communication module and including a processor and a memory,

wherein the memory is configured to store a main database including a plurality of input data and an auxiliary database including a plurality of categories, wherein each of the plurality of input data includes at least one first response data and wherein each of the plurality of categories includes at least one second response data,

wherein the processor is operably coupled to the memory and configured to:

receive a user input entered to the first electronic device using the user interface, from the first electronic device;

extract first information from the user input;

in response to identifying that input data matching the first information is identified among the plurality of input data, transmit, to the first electronic device, first response data corresponding to the input data matched the first information as a processing result for the user input;

wherein the processor is further configured to, in response to identifying that the input data matching the first information is not identified among the plurality of input data:

identify an emotion for a user based on at least a portion of the user input;

identify a category corresponding to an identified emotion among the plurality of categories included in the auxiliary database;

identify second response data corresponding to the identified category; and

transmit the second response data as the processing result for the user input to the first electronic device.

15. The system of claim 14 , wherein the processor is further configured to:

cause a capsule or domain supporting a chatting mode using an utterance of a user to be executed in the first electronic device, based in part on the user input.

16. The system of claim 14 , wherein the processor is further configured to:
