Abstract
A validity determination apparatus according to one embodiment includes: circuitry configured to acquire a natural sentence; output a semantic representation by executing semantic parsing with the natural sentence as an input; calculate a first alignment score representing a relationship between input/output tokens of the natural sentence and the semantic representation; calculate a second alignment score of a word unit from a relationship between a token included in the input/output tokens and a word; extract natural sentence content words by executing part-of-speech parsing on the natural sentence; a grammar parser configured to extract semantic representation content words by executing grammar parsing on the semantic representation; and determine whether the semantic representation is valid on the basis of the second alignment score, the natural sentence content words, and the semantic representation content words.
