Abstract: In order to improve the the results of statistical machine translation in Chinese-English,the paper proposed a language model based on dependency syntax relationship.In the more mature features of phrase-based statistical translation,this new model can further constraint the result of the NBEST sequence by decoding,recalculate the NBEST sequence scores,and adjust the NBEST sequence to get a better translation．Experiments with a test set with baseline of "Pharaoh" in 500English sentences and the final experimental results show that the proposed language model with dependency syntax relationship can improve the accuracy of Chinese-English’s best statistical translation in some extent.
