【摘要】 简要介绍了统计机器翻译的国内外现状,对当前统计机器翻译的主流方法进行了理论上的探讨。首先讨论了对数线性模型,然后进一步描述了对数线性模型的特征选择、参数训练和搜索算法,最后在此基础上进行了初步的实验。实验结果表明:基于短语的统计机器翻译方法能够取得较好的翻译效果,值得做更深一步的研究。更多还原

【Abstract】 This paper briefly introduces the research status of statistical machine translation,and mainly focused on the log-linear model at the basis of the current dominating research methods.We describes the feature selection,parameter training,decoding algorithm,and makes some primary experiments on the log-linear model,the results show that this kind of model can achieve good performance in translation task.更多还原
