句法分析在自然语言处理的实际应用中扮演着重要的角色。当前各少数民族语言包括蒙古语的句法分析研究还处在相对滞后的阶段。同时给其他相关研究带来了相应的困难。该文提出了一种基于双语约束的蒙语的无监督依存分析方法。能够在无需蒙语依存树库及蒙语句法的情况下,对蒙语进行无监督的依存句法分析。并且获得了较好的效果,在人工标注的测试集上有向及无向的正确率分别达到了67.2%及73.3%,可以实际应用到自然语言处理中了。
Syntax parsing plays important role in natural language processing.However,there is less research on syntax parsing of minority languages,including Mongolian,which brings some difficulty to other related research.We present an unsupervised dependency parsing method for Mongolian based on bilingual constraint in this paper.Our method can parse Mongolian without Mongolian tree bank and syntax characteristic.And we get a result of 73.3%(undir) and 66.2%(dir) on test set.And it is applicableto practical application.
