Realization method and realization system for simultaneously identifying bilingual terms and word alignment

Abstract

The invention relates to a realization method and a realization system for simultaneously identifying bilingual terms and word alignment. The realization method comprises the steps of performing word segmentation on a pair of a source language sentence and a target language sentence to obtain a source language word group and a target language word group; performing word alignment on the source language word group and the target language word group to obtain aligned initial words; identifying terms in the source language sentence and the target language sentence, and obtaining initial monolingual terms; performing term alignment in combination with the aligned initial words and the initial monolingual terms to obtain aligned initial terms; taking the aligned initial terms as anchor points, and obtaining a primary bilingual term candidate list; performing bilingual term identification on the primary bilingual term candidate list to obtain a secondary bilingual term candidate list; and performing secondary bilingual term identification and word alignment on the secondary bilingual term candidate list to obtain final bilingual terms and final aligned words. According to the realization method, automatic term identification and word alignment performance can be realized and final machine translated text quality is improved.

Description

technical field [0001] The present invention relates to the technical field of natural language processing, and more specifically, to an implementation method and implementation system for simultaneously recognizing bilingual terms and word alignment. Background technique [0002] Machine translation is the use of computers to convert between different languages. The translated language is usually called the source language, and the resulting language translated into is called the target language. Machine translation is the process of converting from a source language to a target language. Word alignment is a core task of statistical machine translation. It discovers mutually translated language fragments from bilingual parallel corpora, and is the main source of translation knowledge. In short, word alignment is the translation of a word in the source language sentence from which word in the target language. Such as figure 1 As shown, a word can be translated into one o...
