借助汉-越双语词对齐语料构建越南语依存树库

由于对越南语的研究工作相对较少,因此还没有建立规模相对较大的依存树库。相对于已经拥有了形态丰富、语料成熟的汉语,越南语的依存句法分析要困难得多,所以该文提出了一种借助汉-越双语词对齐语料构建越南语依存树库的方法。首先对汉语-越南语句子对进行词对齐处理,然后对汉语句子进行依存句法分析。最后结合越南语本身的语言特点和有关的语法规则将汉语的依存关系通过汉-越双语词对齐关系映射到越南语句子中,从而生成越南语的依存树库。实验表明,该方法简化了人工收集和标注越南语依存树库的过程,节省了人力和构建树库的时间。实验结果表明,该方法相比采用机器学习的方法准确率明显提高。

Vietnamese Dependency Treebank Construction Via Chinese-Vietnamese Bilingual Corpus

To leverage the rich and mature Chinese corpus for Vietnamese dependency treebank, this paper presents an approach to Vietnamese Dependency Treebank construction via Chinese-Vietnamese bilingual corpus with word alignments. Based on the word alignment information, the Chinese dependency parsing is mapped into Vietnamese Dependency structure. Experimental results show that this approach can simplify the process of manual collection and annotation of Vietnamese Treebank, also can save manpower and time building the Treebank. Experimental results show that the accuracy of this method compared to machine learning methods has improved significantly.
