SENTENCE STRUCTURE VECTORIZATION DEVICE, SENTENCE STRUCTURE VECTORIZATION METHOD, AND STORAGE MEDIUM STORING SENTENCE STRUCTURE VECTORIZATION PROGRAM

摘要

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.
