Patent ID: 10049105

Abstract:
[Object] An object is to provide an apparatus for attaining highly precise word alignment.[Solution] The apparatus includes: selecting means receiving a bilingual sentence pair and a word alignment for the bilingual sentence pair, for successively selecting words fj of a sentence in a first language in a prescribed order; and a recurrent neural network (RNN) 100, computing, for all words of the sentence in the first language, a score 102 representing a probability that a word pair consisting of the word fj and a word ea_{j} aligned with the word fj by a word alignment aj in a second language of the bilingual sentence pair is a correct word pair, and based on this score, for computing a score of the word alignment aj. When computing a score of word pair (fj, ea_{j}), RNN 100 computes a score 102 of the word pair (fj, ea_{j}) based on all word alignments a1j-1 selected by the selecting means prior to the word fj of the word pair (fj, ea_{j}), of the word alignments aj, by means of a recurrent connection 118.
