基于组合范畴语法的现代汉语两种结构歧义的消解

摘要

Structural ambiguity resolution is a key and difficult area in the field of natural language information processing. The two kinds of structural ambiguities produced by different jurisdictions of adjectives, and by noun phrases consisting of more than two nouns in modern Chinese can be disambiguated by using the proof tree in compostional category grammar. The purpose of disambiguation can be achieved by assigning different categories to entries in structural ambiguity sentences and adopting different sequences for the contiguous expressions in deductive trees.%结构歧义消解是自然语言信息处理的重点和难点研究领域.利用组合范畴语法的推演树,可以对现代汉语中由形容词的不同管辖范围、两个以上的名词组成的名词短语所产生的两种结构歧义句进行消解.可以通过对结构歧义句中词条指派不同的范畴,以及对推演树中表达式的毗连采取不同的先后顺序,达到歧义消解的目的.
