| English Abstract | 针对为汉藏辅助翻译系统建立汉藏多词单元翻译词典这一任务,该文提出了CMWEPM模型。该模型首先依据关联度和结合度来确定汉语语料中多词单元的边界,然后根据词对齐信息分别抽取严格和约束多词单元等价对,从而形成汉藏多词单元等价对。CMWEPM模型根据不同长度和频次对多词单元进行分类,并为不同类型设定不同阈值,最终提高了汉藏多词单元等价对的召回率,从而能够间接地提高汉藏辅助翻译系统的翻译质量。 |
| Abstract | This paper aims to construct Chinese-Tibetan multi-word equivalence dictionary for machine-aided translation system.It proposes CMWEPM model which can extract multi-word equivalences in two phases.First,CMWEPM defines the boundary of Chinese multi-word units by collocation and binding degree.Then it extracts strict and constrained multi-word equivalences based on word alignments,respectively.CMWEPM model classifies multi-word units according to its lengths and frequency,and set different thresholds for different types.This strategy can improve the translation quality with higher recall of multi-word equivalent pairs that play a significant role in Chinese-Tibetan machine-aided translation system. |
