摘要 首先介绍了短语结构句法树和依存树,比较了两者的差别。然后通过构建基于短语结构句法分析和基于依存句法分析的两个不同的语义角色标注系统,在实验数据的基础上,重点分析短语结构句法分析和依存句法分析的差别以及两者对语义角色标注的影响。实验结果表明,基于依存句法分析的语义角色标注系统的性能略好于基于短语结构句法分析的语义角色标注系统。 Firstly, two different syntactic forms, phrase structure-based syntactic tree and dependency tree are introduced in this paper with the comparison of their differences, Then by constructing two different SRL systems based on the above syntactic forms, and according to a series of experiment data, the difference of two syntactic forms and their effects on SRL are analysed as the focus. Our experimental results show that the dependency relation-based SRL performs slightly better than the phrase structure-based SRL.
