Statistical machine translation method and system

Abstract

The invention discloses a statistic machine translation method and a statistic machine translation system. The method comprises the following steps that: firstly, phrase division of a source language statement is performed and bilingual phrases are searched from a bilingual phrase table according to divided phrases; secondly, the matching degree of the divided phrases and the bilingual phrases is inspected; under the condition of complete matching, the bilingual phrases are added into a candidate phrase table and the fourth step is executed; under the condition of partial matching, the third step is executed; thirdly, a translation template is constructed according to the divided phrases and the bilingual phrases, and word translations of the divided phrases which are different from the bilingual phrases are filled into the translation template to generate novel bilingual phrases which are then added into the candidate phrase table; fourthly, the source language statement to be translated is translated according to the candidate phrase table. The statistic machine translation method and the statistic machine translation system can effectively improve the translation quality under the condition that bilingual corpuses are limited and solve the problem of data sparseness of the statistic machine translation system.

Description

technical field [0001] The invention relates to the technical field of machine translation, in particular to a phrase-based statistical machine translation method and system. Background technique [0002] With the continuous progress of society and the rapid development of economy, international exchanges and cooperation are becoming increasingly close, which puts forward higher requirements for translation between different languages. The translation between natural languages ​​(also known as machine translation) with the help of powerful storage and computing power of computers can greatly reduce translation costs and improve work efficiency. In addition, the booming Internet and multilingual documents provide us with a large number of parallel corpora, laying a solid foundation for statistical machine translation. [0003] Statistical machine translation is a corpus-based translation method. Its main idea is to construct a mathematical model for the translation process, ...
