An information processing device includes an acquisition unit that acquires a plurality of character strings, a morphological analysis execution unit that executes morphological analysis on the plurality of character strings, and a generation unit that generates a learned model for inferring meaning of a first word included in a plurality of words among a plurality of speech-parted words obtained by executing the morphological analysis on the plurality of character strings based on a plurality of words as a plurality of predicates among the plurality of speech-parted words and a plurality of words among the plurality of speech-parted words.

Information processing device, and generation method

A sentence structure vectorization device includes processing circuitry to generate a plurality of morphemes by performing morphological analysis on an input sentence; to generate a dependence structure graph regarding the plurality of morphemes by performing dependency parsing on the plurality of morphemes; and to generate a sentence structure vector by extracting a plurality of pieces of partial structure information from the dependence structure graph and converting a morpheme string corresponding to the plurality of pieces of partial structure information into a numerical sequence.

Sentence structure vectorization device, sentence structure vectorization method, and storage medium storing sentence structure vectorization program

A similar expression collecting unit () collects a word/phrase of an expression similar to an analysis viewpoint word/phrase and a word embedding corresponding the word/phrase from distributed representations of words data. A dimension selecting unit () selects a dimension of a word embedding depending on the analysis viewpoint word/phrase, and compresses a word embedding corresponding to the word/phrase collected by the similar expression collecting unit () in the selected dimension.

Data analyzer and data analysis method

A language model generating device according to the present invention includes: a paraphrase generating unit to generate, by using morphemes of a phrase included in learning example sentences that include a plurality of sentences and using synonyms for original expressions of the morphemes, a plurality of paraphrases that include a combination of an original expression of a morpheme and a synonym for an original expression of a morpheme and a combination of synonyms for original expressions of morphemes; and a language model generating unit to generate a language model that is based on an n-gram model from the plurality of paraphrases generated and the learning example sentences.
