Abstract

An interactive system, an first server and a control method thereof are provided. According to a method for controlling the interactive system, the first server includes storing query data generated by inputting a keyword to a pre-analyzed utterance pattern by an first server, receiving a user'"'"'s voice, converting the user'"'"'s voice to voice data and transmitting the voice data to the first server by a display apparatus and in response to the voice data being received, performing a search regarding the user'"'"'s voice by being the first server using the stored query data.

1. A method of controlling an interactive system, the method comprising:

parsing, by a server, a plurality of voice data received from a plurality of users;

identifying, by the server, an utterance pattern based on the parsed plurality of voice data, and obtaining a plurality of keywords corresponding to at least one from among contents and a searching word list of a search engine;

obtaining, by the server, query data comprising a plurality of queries by combining at least one keyword of the obtained plurality of keywords with the identified utterance pattern;

storing, by the server, the obtained query data; and

based on a voice data being received from a display apparatus of a user, performing, by the server, a search related to a voice of the user by comparing the voice data with the stored query data.

2. The method as claimed in claim 1, wherein the performing the search comprises:

in response to the voice data received from the display apparatus being consistent with the one of the plurality of queries stored in a cache memory of a first server, performing the search with the one of the plurality of queries; and

in response to the voice data received from the display apparatus being inconsistent with the one of the plurality of queries stored in the cache memory of the first server, performing natural language processing related to the voice data and performing the search according to a result of the natural language processing.

3. The method as claimed in claim 1, wherein the analyzing the utterance pattern comprises collecting utterances of the plurality of users and parsing the utterances.

4. The method as claimed in claim 3, wherein the storing comprises:

collecting the voice of the user, analyzing the utterance pattern by parsing the voice of the user, and generating the query data by a second server; and

receiving the query data from the second server and storing the query data in a cache memory by a first server.

5. The method as claimed in claim 4, wherein the second server performs analyzing the utterance pattern and generating the query data in response to the voice of the user being received less than a predetermined number of times.

6. The method as claimed in claim 1, wherein each keyword of the plurality of keywords is related to at least one of first content generated within a time period or second content searched more than a predetermined number of times within the time period.

7. The method as claimed in claim 1, further comprising;

deleting, from the query data, a query which is not used for the search within a time period.

8. An interactive system comprising:

a first server; and

a display apparatus configured to receive a voice of a user, convert the voice to voice data and transmit the voice data to the first server,

wherein the first server is configured to;

parse a plurality of voice data received from a plurality of users,

identify an utterance pattern based on the parsed plurality of voice data and obtaining a plurality of keywords corresponding to at least one from among contents and a searching word list of a search engine,

obtain query data comprising a plurality of queries by combining at least one keyword of the obtained plurality of keywords with the identified utterance pattern,

store the obtained query data, and

based on the voice data being received from the display apparatus of the user, perform, by the first server, a search related to the voice of the user by comparing the voice data with the stored query data.

9. The interactive system as claimed in claim 8, wherein the first server is further configured to:

in response to the voice data being consistent with the one of the plurality of queries stored in a cache memory, perform the search with the one of the plurality of queries; and

in response to the voice data being inconsistent with the one of the plurality of queries stored in the cache memory, perform a natural language processing related to the voice data, and perform the search according to a result of the natural language processing.

10. The interactive system as claimed in claim 8, further comprising a second server configured to collect the voice of the user, parse the voice of the user and analyze the utterance pattern.

11. The interactive system as claimed in claim 8, further comprising a second server;

wherein the second server is configured to collect the voice of the user, analyze the utterance pattern by parsing the voice of the user, generate the query data, and transmit the query data to the first server; and

wherein the first server is further configured to receive the query data from the second server and store the received query data in a cache memory.

12. The interactive system as claimed in claim 11, wherein the second server is further configured to analyze the utterance pattern and generate the query data in response to a number of the voice of the user being less than a predetermined number.

13. The interactive system as claimed in claim 11, wherein each keyword of the plurality of keywords is related to at least one of first content generated within a time period or second content searched more than a predetermined number of times within the time period.

14. The interactive system as claimed in claim 11, wherein the first server is further configured to delete, from the query data, a query which is not used for the search within a time period.

15. The interactive system of claim 11, wherein the first server is further configured to delete, from the query data, a query which is not used for the search within a time period.

16. The interactive system of claim 8, further comprising a second server configured to compare the stored query data, and in response to the voice data being received, perform the search related to the voice of the user by comparing the voice data with the stored query data.

17. The interactive system of claim 16, wherein the second server is further configured to analyze the utterance pattern and generate the query data in response to a number of the voice of the user being less than a predetermined number.

18. The interactive system of claim 16, wherein each keyword of the plurality of keywords is related to at least one of first content generated within a time period or second content searched more than a predetermined number of times within the time period.

19. A method for controlling a server, the method comprising:

parsing, by the server, a plurality of voice data received from a plurality of users;

identifying, by the server, an utterance pattern based on the parsed plurality of voice data and obtaining a plurality of keywords corresponding to at least one from among contents and a searching word list of a search engine;

obtaining, by the server, query data comprising a plurality of queries by combining at least one keyword of the obtained plurality of keywords with the identified utterance pattern;
