自然语言解析器是一个制定语法结构句子的程序.概率解析器使用语言知识获得hand-parsed句子来产生最可能的分析新句子.斯坦福大学的自然语言解析器是一个实现英语、德语、汉语、阿拉伯语概率PCFG和依存解析器.链接语法解析器是根据链接文法和英语语法理论的一个英语语法解析器(包括其他语言).PC-PATR是一个语法解析器,使用PARTII作为一项规则描述语言.这是一个实现了PARTII形式主义计算语言.%A natural language parser is a program that works out the grammatical structure of sentences. The Stanford natural language parser is a Java implementation of a probabilistic PCFG and dependency parser for English, German, Chinese, and Arabic. The link grammar parser is a syntactic parser of English, based on link grammar, an original theory of English syntax. PC-PATR is a syntax analyzer, using PART-II as a rule description language. It is an implementation of the PART-II computational linguistic formalism ( plus a few enhancements) for personal computers.
