Abstract:

Based on the current statistical machine translation，the size of corpus and the accuracy of word alignment mainly affect the performance of SMT systems.Though large bilingual corpus can improve the accuracy of word alignment and the performance of the system，at the cost of increasing the load of the system at the same time.So nowdays the research about statistical machine translation is not only on the basis of using large bilingual corpus，but also seeks other methods to improve the performance of the system.This paper proposes an approach，in which the bilingual dictionary is integrated in the SMT system.The approach can improve the accuracy of word alignment，and can also get a better result，and to a certain extent，the problem of Sparse Data is eased.

Key words: statistical machine translation, bilingual dictionary, bilingual corpus
