Embodiment Construction

[0023] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only parts related to the present invention are shown in the drawings but not all content.

[0024] figure 1 A first embodiment of the invention is shown.

[0025] figure 1 It is a schematic flowchart of the bilingual corpus data expansion method provided by the first embodiment of the present invention. This method is suitable for expanding the bilingual corpus of the source language-target language corpus based on the source language-pivot language corpus and the pivot language-target language corpus. Specifically, it can be realized by the data expansion device of the bilingual corpus , the device can be configu...

Abstract

The invention discloses a data expansion method and device for a bilingual corpus. The data expansion method of the bilingual corpus includes: searching in the source language-pivot language corpus for at least one first pivot language phrase that matches the semantics of the first source language phrase; at least one second source language phrase that semantically matches the first pivot language phrase; searching the pivot language-target language corpus for at least one first target language phrase that semantically matches each of the first pivot language phrases; Combining the second source language phrase in the source language phrase set with the first target language phrase in the target language phrase set; storing the phrase pair between the source language phrase and the target language phrase formed by the combination in the source language‑target language corpus. The invention expands the data in the bilingual corpus and solves the data sparse problem in the bilingual corpus.

Description

technical field [0001] The invention relates to the technical field of machine translation, in particular to a data expansion method and device for a bilingual corpus. Background technique [0002] Machine translation systems can be divided into rule-based machine translation systems, instance-based machine translation systems, and statistical-based machine translation systems. The machine translation system based on statistics is a kind of machine translation system that emerged in the 1990s, and it is also the most important machine translation system at present. It does not need to manually write rules, and is applicable to all languages, so it is widely used. [0003] The translation quality of statistical-based machine translation systems largely depends on the quality of the corpus. That is, the more data in the corpus and the higher the quality, the higher the translation quality of the machine translation system based on statistics. At the beginning of the establi...
