【摘要】 通过汉语到英语的翻译实验以及对结果译文的分析,对基于词的模型、基于短语的模型和基于句法的模型的翻译性能进行了比较。结果表明基于短语的模型性能优于其他两个模型,但是使用的参数较多;基于句法的模型虽然翻译性能不理想,但可以用较少的参数表达更丰富的信息,值得深入研究。更多还原

【Abstract】 According to the linguistics information, there are primary word-basd,phrased-based and syntax-based translation models:By analyzing and comparing the translation results,it’s found that the performance of the phrase-based translation model is the best.The syntax-based model is the worst,but it uses less parameters than the other two.It encodes rich information with a few parameters,so it’s deserved further research.更多还原
