目前主流的词汇化句法分析方法仅仅考虑词语之间的语义依存关系
而没有引入语义搭配和语义类等语义信息.配价是词语的一个比较本质的特点
一旦一个词语的配价结构确定下来
它应该和怎样的词进行搭配也就比较清楚了
从而也可以比较直接地导出句子的结构.本文结合中心词驱动句法分析模型
提出了基于配价结构和语义依存关系的句法分析模型.模型在规则的分解及概率计算中引入丰富的语义信息
既包括语义依存信息
也包括配价结构等语义搭配信息.用改进的句法分析模型进行句法分析实验
实验结果表明
精确率和召回率分别为88.76%和87.43%
综合指标F值比Collins的中心词驱动句法分析模型提高了6.65个百分点.
The mainstream lexicalized syntactic parsing models currently only utilized semantic dependency between words
and did not incorporate other semantic information such as semantic collocation and semantic category.valencyis a essential semantic feature of words
once the valency of word is determined
the collocation of the word is clear
and the sentence structure can be directly derived.Thus a syntactic parsing model combining valence structure with semantic dependency is purposed on the base of head-driven statistical syntactic parsing models.The parsing model incorporates rich semantic information including semantic dependency and semantic collocation in the decomposition and probability computation of the rules.Experiments are conducted for the refined statistical parser
it achieves 88.76% precision and 87.43% recall
F measure is improved 6.65% comparing with the head-driven parsing model introduced by Collins.
