Abstract

A display apparatus and a method for questions and answers includes a display unit includes an input unit configured to receive user'"'"'s speech voice; a communication unit configured to perform data communication with an answer server; and a processor configured to create and display one or more question sentences using the speech voice in response to the speech voice being a word speech, create a question language corresponding to the question sentence selected from among the displayed one or more question sentences, transmit the created question language to the answer server via the communication unit, and, in response to one or more answer results related to the question language being received from the answer server, display the received one or more answer results. Accordingly, the display apparatus may provide an answer result appropriate to a user'"'"'s question intention although a non-sentence speech is input.

Claims

1. A display apparatus including a display unit, the display apparatus comprising:

an input unit configured to receive a user'"'"'s speech;

a communication unit configured to perform data communication with an answer server; and

a processor configured to;

create and display at least one question sentence using the speech in response to the speech being a word speech,

create a question language corresponding to a question sentence selected from among the displayed at least one question sentence,

transmit the question language to the answer server via the communication unit, and,

in response to at least one answer result related to the question language being received from the answer server, display the received at least one answer result.

2. The display apparatus as claimed in claim 1, further comprising:

a storage unit configured to store a plurality of sentences, and keywords corresponding to characteristic vectors for the plurality of respective sentences,

wherein the processor compares a similarity in a pronunciation column between the stored keywords corresponding to the characteristic vectors for the plurality of respective sentences and the word speech, determines a sentence including a keyword having a high similarity with the word speech, and displays the determined sentence as the at least one question sentence.

3. The display apparatus as claimed in claim 2, wherein, in response to a plurality of sentences being determined as the at least one question sentence, the processor displays the plurality of sentences determined as the at least one question sentence in order of a highest number of times the respective at least one question sentence has been previously selected based on selection history information for each of the plurality of sentences.

4. The display apparatus as claimed in claim 2, wherein, in response to a plurality of sentences being determined as the at least one question sentence, the processor selects and displays a predetermined number of sentences having a highest number of times the respective at least one question sentence has been previously selected based on selection history information for each of the plurality of sentences.

5. The display apparatus as claimed in claim 1, wherein, in response to keywords related to the word speech being received from the answer server, the processor combines the received keywords, creates the question sentence with respect to the speech, and displays the question sentence.

6. The display apparatus as claimed in claim 5, wherein the answer server is a triple structure knowledge base server and extracts the keywords related to the word speech using attribute information related to the word speech.

7. The display apparatus as claimed in claim 2, wherein, when there is no sentence including the keyword having the highest similarity with the word speech, the processor receives the word speech and the keywords from the answer server, combines the received keywords, and creates a question sentence related to the word speech.

8. The display apparatus as claimed in claim 1, wherein, in response to the user'"'"'s speech being a sentence speech, the processor extracts an object name from the user'"'"'s speech using a natural language processing based algorithm and creates a question language based on the extracted object name.

9. A method, performed by a display apparatus, of providing questions and answers, the method comprising:

receiving a user'"'"'s speech;

in response to the user'"'"'s speech being a word speech, creating and displaying at least one question sentence using the user'"'"'s speech;

creating a question language corresponding to a question sentence selected from among the displayed at least one question sentence and transmitting the question language to an answer server;

receiving at least one answer result related to the question language from the answer server; and

displaying the received at least one answer result.

10. The method as claimed in claim 9, wherein the creating and displaying of the one or more question sentences includes:

comparing a similarity in a pronunciation column between keywords corresponding to characteristic vectors for each of a plurality of previously stored sentences and the word speech,

determining a sentence including a keyword having a high similarity with the word speech, and

displaying the determined sentence as the at least one question sentence.

11. The method as claimed in claim 10, wherein the creating and displaying of the one or more question sentences includes:

in response to a plurality of sentences being determined as the at least one question sentence, displaying the plurality of sentences determined as the at least one question sentence in order of a highest number of times the respective at least one question sentence has been previously selected based on selection history information for each of the plurality of sentences.

12. The method as claimed in claim 10, wherein the creating and displaying of the one or more question sentences includes:

in response to a plurality of sentences being determined as the at least one question sentence, selecting and displaying a predetermined number of sentences having a highest number of times the respective at least one question sentence has been previously selected based on selection history information for each of the plurality of sentences.

13. The method as claimed in claim 9, wherein the creating and displaying of the one or more question sentences includes:

in response to keywords related to the word speech being received from the answer server, combining the received keywords, creating the question sentence with respect to the speech, and displaying the created question sentence.

14. The method as claimed in claim 13, wherein the answer server is a triple structure knowledge base server and extracts keywords associated with the core vocabulary using attribute information related to the core vocabulary.

15. The method as claimed in claim 10, wherein the creating and displaying of the one or more question sentences includes:

when there is no sentence including the keyword having the highest similarity with the word speech, receiving the keywords associated with the word speech from the answer server, combining the received keywords, and creating and displaying a question sentence related to the word speech.

16. The method as claimed in claim 9, further comprising:

determining whether the user'"'"'s speech is a word speech or a sentence speech,

wherein the transmitting includes, in response to the user'"'"'s speech being a sentence speech, extracting an object name from the user'"'"'s speech using a natural language processing based algorithm, creating a question language based on the extracted object name, and transmitting the created question language to the answer server.

17. A non-transitory computer-readable storage medium coupled to a display apparatus that provides questions and answers, and storing a computer program for executing the following operations of:

receiving a user'"'"'s speech;

if the user'"'"'s speech is a word speech, creating and displaying at least one question sentence using the user'"'"'s speech;

creating a question language corresponding to the question sentence selected from among the displayed at least one question sentence and transmitting the question language to an answer server;

receiving at least one answer result related to the question language from the answer server; and

displaying the received at least one answer result.
