Spoken language understanding apparatus, method, and program
First Claim
1. A spoken language understanding apparatus comprising processing circuitry coupled to a memory, the processing circuitry configured to:
- store first situation information about a situation assumed in advance, a first semantic representation representing a meaning of a sentence assumed as an input from a user, intention information representing an intention to be estimated, and a first value representing a degree of application of the first semantic representation to the first situation information and the intention information in association with each other;
acquire a natural sentence;
acquire second situation information about a situation when acquiring the natural sentence;
analyze the natural sentence and generate a second semantic representation representing a meaning of the natural sentence; and
obtain an estimated value based on the first value associated with the first situation information and the first semantic representation, the estimated value corresponding to the second situation information and the second semantic representation.

Abstract
According to one embodiment, an apparatus includes a storage unit, a first acquisition unit, a second acquisition unit, an analyzer, and a recognition unit. The storage unit stores first situation information about a situation assumed in advance, a first representation representing a meaning of a sentence assumed, intention information representing an intention to be estimated, and a first value representing a degree of application of the first representation to the first situation information and the intention information. The first acquisition unit acquires a natural sentence. The second acquisition unit acquires second situation information about a situation when acquiring the natural sentence. The analyzer analyzes the natural sentence and generates a second representation representing a meaning of the natural sentence. The recognition unit obtains an estimated value based on the first value associated with the first situation information and the first representation.

16. A spoken language understanding method comprising:
-
storing in a first storage unit first situation information about a situation assumed in advance, a first semantic representation representing a meaning of a sentence assumed as an input from a user, intention information representing an intention to be estimated, and a first value representing a degree of application of the first semantic representation to the first situation information and the intention information in association with each other; acquiring a natural sentence; acquiring second situation information about a situation when acquiring the natural sentence; analyzing the natural sentence and generating a second semantic representation representing a meaning of the natural sentence; and obtaining, from the first storage unit, an estimated value based on the first value associated with the first situation information and the first semantic representation corresponding to the second situation information and the second semantic representation.

17. A non-transitory computer readable medium storing a computer program which is executed by a computer to provide the steps of:
-
storing in a first storage unit first situation information about a situation assumed in advance, a first semantic representation representing a meaning of a sentence assumed as an input from a user, intention information representing an intention to be estimated, and a first value representing a degree of application of the first semantic representation to the first situation information and the intention information in association with each other; acquiring a natural sentence; acquiring second situation information about a situation when acquiring the natural sentence; analyzing the natural sentence and generating a second semantic representation representing a meaning of the natural sentence; and obtaining, from the first storage unit, an estimated value based on the first value associated with the first situation information and the first semantic representation corresponding to the second situation information and the second semantic representation.

18. A spoken language understanding apparatus comprising processing circuitry coupled to a memory, the processing circuitry configured to:
-
store a first situation ID corresponding to first situation information about a situation assumed in advance, a first semantic representation representing a meaning of a sentence assumed as an input from a user, an intention ID corresponding to intention information representing an intention to be estimated, and a first value of conditional probability of the first semantic representation to the first situation ID and the intention ID; acquire a natural sentence; acquire a second situation ID about a situation when acquiring the natural sentence; analyze the natural sentence and generate a second semantic representation representing a meaning of the natural sentence; and obtain an estimated value based on the first value associated with the first situation ID and the first semantic representation, the estimated value corresponding to the second situation ID and the second semantic representation.
