句式结构树库的自动构建研究

Automatic Construction of Sentence Pattern Structure Treebank

句式结构树库是以句本位语法为理论基础构建的句法资源,对汉语教学以及句式结构自动句法分析等研究具有重要意义。目前已有的句式结构树库语料主要来源于教材领域,其他领域的标注数据较为缺乏,如何高效地扩充高质量的句法树库是值得研究的问题。人工标注句法树库费时费力,树库质量也难以保证,为此,该文尝试通过规则的方法,将宾州中文树库(CTB)转换为句式结构树库,从而扩大现有句式结构树库的规模。实验结果表明,该文提出的基于树库转换规则的方法是有效的。

Sentence pattern structure treebank is developed according to the theory of sentence-based grammar,which is of great significance to Chinese teaching.To further expand such treebank from Chinese as second language textbooks and Chinese textbooks to other domains,we propose a rule-based method to convert a phrase structure treebank named Penn Chinese Treebank(CTB)into a sentence pattern structure treebank so as to increase the size of the existing treebank.The experimental results show that our proposed method is effective.
