WORD ALIGNMENT MODEL CONSTRUCTION APPARATUS, MACHINE TRANSLATION APPARATUS, WORD ALIGNMENT MODEL PRODUCTION METHOD, AND RECORDING MEDIUM
Document Type and Number:
WIPO Patent Application WO/2017/038996
Kind Code:
A1
Abstract:
[Problem] It has hitherto been impossible to accurately perform word alignment of a small-size parallel text corpus. [Solution] This word alignment model construction apparatus is provided with: a probability information calculation unit that, for each word pair included in a parallel text sentence included in small-size parallel text data, repeats a loop twice or more for one word pair to calculate first correspondence probability information that forms a pair with the one word pair, by using an initial value or the first correspondence probability information calculated in a previous loop, second correspondence probability information that forms a pair with one word pair included in a large-size word alignment model, and parallel text sentence word position probability information corresponding to one word pair in a parallel text sentence; and a correspondence probability information accumulation unit that accumulates, in association with each word pair, the first correspondence probability information calculated finally by the probability information calculation unit, in a small-size word alignment model storage unit. Thus, word alignment of the small-size parallel text corpus can be accurately performed.
