Learning apparatus and method
First Claim
1. A learning apparatus that uses utterance intention of a user, the utterance intention being inferred from a first text representing results of speech recognition of the user'"'"'s utterances, the learning apparatus comprising:
- a first storage which stores a plurality of similarity information items, each including at least (i) a second text representing results of speech recognition of a set of similar utterances included in a dialog history, (ii) intention candidates inferred based on utterances included in the similar utterances and considered to result in successful dialogs, and (iii) certainty degrees representing a certainty with which the intention candidates are regarded as being identical to intentions of the second text; and
a processing circuitry configured to;
detect a similarity information item as a corresponding similarity information item from the plurality of similarity information items, the corresponding similarity information item including a second text identical to the first text; and
correct the utterance intention to an intention candidate included in the corresponding similarity information item when a certainty degree included in the corresponding similarity information item is not less than a threshold.

Abstract
According to one embodiment, a learning apparatus includes a first storage and a processing circuitry. The first storage stores a plurality of similarity information items, each including at least a second text, intention candidates and certainty degrees representing a certainty with which the intention candidates are regarded as being identical to intentions of the second text. The processing circuitry detects corresponding similarity information item including the second text identical to a first text from the plurality of similarity information items, corrects a utterance intention to an intention candidate included in the corresponding similarity information item where a certainty degree included in the corresponding similarity information item is not less than a threshold.

14. A learning method that uses utterance intention of a user, the utterance intention being inferred from a first text representing results of speech recognition of the user'"'"'s utterances, the learning method comprising:
-
storing, in a first storage, a plurality of similarity information items, each including at least (i) a second text representing results of speech recognition of a set of similar utterances included in a dialog history, (ii) intention candidates inferred based on utterances included in the similar utterances and considered to result in successful dialogs, and (iii) certainty degrees representing a certainty with which the intention candidates are regarded as being identical to intentions of the second text; detecting a similarity information item as a corresponding similarity information item from the plurality of similarity information items, the corresponding similarity information item including a second text identical to the first text; and correcting the utterance intention to an intention candidate included in the corresponding similarity information item when a certainty degree included in the corresponding similarity information item is not less than a threshold.

15. A non-transitory computer readable medium including computer executable instructions, wherein the instructions, when executed by a processor, cause the processor to perform a method that uses utterance intention of a user, the utterance intention being inferred from a first text representing results of speech recognition of the user'"'"'s utterances, the method comprising:
-
storing, in a first storage, a plurality of similarity information items, each including at least (i) a second text representing results of speech recognition of a set of similar utterances included in a dialog history, (ii) intention candidates inferred based on utterances included in the similar utterances and considered to result in successful dialogs, and (iii) certainty degrees representing a certainty with which the intention candidates are regarded as being identical to intentions of the second text; detecting a similarity information item as a corresponding similarity information item from the plurality of similarity information items, the corresponding similarity information item including a second text identical to the first text; and correcting the utterance intention to an intention candidate included in the corresponding similarity information item when a certainty degree included in the corresponding similarity information item is not less than a threshold.
