| 摘 要： | 针对纳西语、汉语因句法结构差异较大而导致双语词语自动对齐较为困难的问题,提出一种融合特征约束模型的纳西-汉语双语词语对齐算法.首先在语料中统计纳西-汉语词语区间扭曲和位置转换特性,并由此建立2个双语词语对齐的特征约束模型;然后将提出的特征约束模型融入词语对齐的对数线性模型框架,并结合最小错误率算法训练模型参数;最终搜索出最佳的词语对齐结果.实验以IBM Model3为词语对齐比较模型,结果表明,该双语词语对齐算法可以使纳西-汉语词语的对齐准确率提升21.9%. |

| Abstract: | A bilingual word alignment algorithm of Naxi-Chinese based on feature constraint models is proposed to reduce the difficulty of bilingual word alignment for Naxi-Chinese which has huge difference in syntactic structure.Two feature constraint models- interval distortion model and position transformation model are established by counting the traits of interval distortion and position transformation in corpus,and are integrated into a log-linear framework of word alignment. Then parameters in the models are tr... |
