语料库、知识获取和句法分析

【摘要】 在这篇文章中,我们将介绍一种基于语料库的汉语句法分析系统。这里,我们用以进行句法分析的知识主要是从有句法标注的语料库中获得的。我们的工作注重在:(1)知识获取及表达;(2)句法分析的算法。在句法分析中我们也用到了语法知识,即依存语法四公理。此外,我们也提出了依存语法第五公理来支持我们的汉语句法分析系统。更多还原

【Abstract】 In this paper, we will introduce a corpus-based Chinese parsing system. The knowledge for parsing is principally extracted from analyzed corpus. Our efforts are concen-trated on. (1) knowledge acquisition and representation; and (2)the parsing scheme. In the parsing some grammatical knowledge i.e.the four axioms of the Dependency Grammar (DG)are used also.In addition,we propose the fifth axiom of DG to support the parsing of Chinese sentences.更多还原
