摘要
自动句法分析中需要确定短语实例的语法功能。文章试图在大规模汉语树库统计的基础上对汉语短语的语法功能分布进行定量分析,以此评估确定短语实例语法功能的三种方法。首先描述了汉语短语结构类充当11种语法功能的情况,然后对短语功能类充当各种语法功能进行统计与分析,最后使用了核心词来估计定中短语的语法功能。在比较分析了不同方法估计短语实例的语法功能的效果后得出结论:汉语短语的语法功能表现出一定的聚合性,但自动句法分析中以类标记来估计短语语法功能效果欠佳。
The grammatical function Based on the large-scale treebank corpus, of a phrase instance should be determined while parsing. the paper makes an investigation into the grammatical functions of Phrases in Mandarin Chinese. The paper first describes the distribution of the grammatical functions of six kinds of phrases categorized by structure with statistical data based large-scale tree corpus. And then the distribution of the grammatical functions of 11 kinds of phrases categorized by function is explored. Finally, The paper compares several methods which are used to distinguish the grammatical function of an instance of np-DZ phrase, and the conclusion that a parser would hardly performance well if it distinguishes the grammatical function of an instance of phrase only by category.
