A Chinese Parser Based on Probabilistic Context Free Grammar 一种基于概率上下文无关文法的汉语句法分析
Our syntactic parser is based on Probabilistic Context Free Grammar, for this mode is the better one in the syntactic pattern. 本文的句法分析器是基于概率上下文无关语法的,这种方法是统计分析模型中比较成功的一种模式。
An inference approach for Chinese probabilistic context-free grammar 汉语概率型上下文无关语法的自动推导
For example, when a Probabilistic Context Free Grammar and the sentence are given, we use the Inside Algorithm to pick-up the probability of the rule; 即采用向内向外算法,在给定一部概率上下文无关语法的前提下,计算句子的概率;
Probabilistic context-free grammar can provide a solution to this problem: select the one whose probability is maximum from the ambiguity. 概率上下文无关语法可以提供对这个问题的解决方法:从歧义中选择概率最大的解释。
