翻译评价方法的区分度分析

Discriminability Analysis of Translation Evaluation

首先简单介绍了目前被广泛应用的两种翻译评价方法BLEU和NIST,然后着眼于它们对翻译系统实际水平的区分程度,参考教育测量领域中的方法,提出了区分度的概念,并通过实验阐明了基于区分度的性能分析方法。实验结果表明这种性能分析方法能够有效地反映出BLEU方法和NIST方法在区分程度上的优劣。

Firstly,this paper simply introduces two widely-applied methods of translation evaluation:BLEU and NIST.Then it focuses on their capability of discriminating translation systems' practical level,referring to the approach in the field of education measure,and proposes a concept of discriminability.An experiment is given to illustrate the performance analysis method based on discriminability.The experimental results indicate this method can effectively reflect the discriminating degree of BLEU and NIST.
