摘要
We propose a method that can achieve the Naxi-English bilingual word automatic alignment based on a log-linear model.This method defines the different Naxi-English structural feature functions,which are English-Naxi interval switching function and Naxi-English bilingual word position transformation function.With the manually labeled Naxi-English words alignment corpus,the parameters of the model are trained by using the minimum error,thus Naxi-English bilingual word alignment is achieved automatically.Experiments are conducted with IBM Model 3 as a benchmark,and the Naxi language constraints are introduced.The final experiment results show that the proposed alignment method achieves very good results:the introduction of the language characteristic function can effectively improve the accuracy of the Naxi-English Bilingual Word Alignment.

This method defines the different Naxi-English structural fea- ture functions, which are English-Naxi interval switching function and Naxi-English bilingual word position transformation function. With the manually labeled Naxi-English words alignment corpus, the parameters of the model are trained by using the minimum error, thus Naxi-English bilingual word alignment is achieved automatical- ly. Experiments are conducted with IBM Model 3 as a benchmark, and the Naxi language con- straints are introduced. The final experiment re- sults show that the proposed alignment method a- chieves very good results： the introduction of the language characteristic function can effectively improve the accuracy of the Naxi-English Bilin- gual Word Alignment.
