| 摘 要： | 语义角色标注是自然语言处理的一个重要研究内容,性能对机器翻译等研究有重大影响。实现了一个基于依存关系的中文名词性谓词语义角色标注平台,并对名词性谓词进行识别,使用最大熵分类模型在Chinese NomBank的转换语料上进行系统实验,对各种词法特征、结构特征及其组合进行了测试,标准语料上F1值达到78.09,基于自动句法树的语料上的F1值达到67.42。

| Abstract: | Semantic Role Labeling is an important component of Natural Language Processing.It plays a critical role in machine translation.This paper explores a Chinese dependency-based Semantic Role Labeling system for Nominal Predicate by using a maximum entropy classifier.In particular,various kinds of lexical,syntactic and semantic features are incorporated to improve the performance with systematic evaluation on the dataset which is transferred from constituent-based corpus(Chinese NomBank).Experiments with vario... |
