Abstract

A method, system, and a computer-readable recording medium for improving a set of at least one semantic unit are provided. According to the present invention, a set of at least one semantic unit may be improved by using a phonetic sound or text.

Claims

1. A method for improving a set including at least one semantic unit, in which the set including the at least one semantic unit is a captured semantic unit set, the method comprising:

receiving an improvement phonetic sound according to utterance of a user;

specifying an improvement semantic unit set on the basis of the improvement phonetic sound;

specifying, as a matched semantic unit set, a semantic unit set to be actually improved within the captured semantic unit set, on the basis of correlation thereof with the improvement semantic unit set; and

replacing the matched semantic unit set within the captured semantic unit set with the improvement semantic unit set.

2. The method of claim 1, wherein

the specifying of an improvement semantic unit set comprises measuring a length of the improvement semantic unit set.

3. The method of claim 2, wherein

the specifying of a matched semantic unit set comprises dividing the captured semantic unit set into a plurality of portions on the basis of intervals between units or the length of the improvement semantic unit set, and expanding the divided portions.

4. The method of claim 3, wherein

the specifying of a matched semantic unit set further comprises comparing each of the plurality of portions of the captured semantic unit set with the improvement semantic unit set.

5. The method of claim 4, wherein

the comparing comprises comparing features of a digital phonetic signal corresponding to each of the plurality of portions of the captured semantic unit set with those of a digital phonetic signal corresponding to the improvement semantic unit set.

6. The method of claim 4, wherein

the comparing comprises comparing a text corresponding to each of the plurality of portions of the captured semantic unit set with a text corresponding to the improvement semantic unit set.

7. The method of claim 6, wherein

the comparing of texts comprises sequentially comparing the two texts in terms of phonetic values or spellings.

8. The method of claim 6, wherein

the comparing of texts comprises comparing the two texts as to whether they belong to the same category or have similar meanings.

9. The method of claim 6, wherein

the comparing of texts comprises comparing the two texts on the basis of key position correlation.

11. A computer-readable recording medium storing a computer program for executing the method according to claim 1.

10. A method for improving a set including at least one semantic unit, in which the set including the at least one semantic unit is a semantic unit set captured from a voice according to utterance of a user, the method comprising:

receiving an improvement text inputted by the user;

specifying an improvement semantic unit set on the basis of the improvement text;

specifying, as a matched semantic unit set, a semantic unit set to be actually improved within the captured semantic unit set, on the basis of correlation thereof with the improvement semantic unit set; and

replacing the matched semantic unit set within the captured semantic unit set with the improvement semantic unit set.

12. An apparatus for improving a set including at least one semantic unit, in which the set including the at least one semantic unit is a captured semantic unit set, the apparatus comprising:

a voice sensing unit configured to receive an improvement phonetic sound according to utterance of a user; and

a semantic unit improving unit configured to specify an improvement semantic unit set on the basis of the improvement phonetic sound, to specify, as a matched semantic unit set, a semantic unit set to be actually improved within the captured semantic unit set, on the basis of correlation thereof with the improvement semantic unit set, and to replace the matched semantic unit set within the captured semantic unit set with the improvement semantic unit set.

13. An apparatus for improving a set including at least one semantic unit, in which the set including the at least one semantic unit is a semantic unit set captured from a voice according to utterance of a user, the apparatus comprising:

a means configured to receive an improvement text inputted by the user; and

a semantic unit improving unit configured to specify an improvement semantic unit set on the basis of the improvement text, to specify, as a matched semantic unit set, a semantic unit set to be actually improved within the captured semantic unit set, on the basis of correlation thereof with the improvement semantic unit set, and to replace the matched semantic unit set within the captured semantic unit set with the improvement semantic unit set.
