摘要 浅层句法分析是近年来自然语言处理领域出现的一个新的语言处理策略。它不要求得到完全的句法分析树,只要求识别其中的某些结构相对简单的成分。它将句法分析分解为两个子任务:(1)语块的识别和分析;(2)语块之间的依附关系分析。浅层句法分析的主要任务是语块的识别和分析。90年代以来,国外在英语的浅层句法方面做了不少工作,国内也有一些学者采用英语中的方法探索汉语的浅层句法分析问题。本文着重介绍英语浅层句法分析中所应用的一些技术,包括基于统计的方法和基于规则的方法。 This paper presents an introductory overview of the studies on shallow parsing for both English and Chinese. The major methods within two paradigms, statistics-based and rule-based, are discussed in detail. Statistics-based methods include HMM-based method, mutual information, chi-square statistics,and dependency probability of heads. Rule-based methods include incremental approach, reductionalist approach, and the methods for learning rules.
