Phrase-structure Grammar

短语结构语法

A type of grammar discussed by Noam Chomsky in his book Syntactic Structures (1957) as an illustration of a generative device. Phrase-structure grammars contain rules (PS-rules) which are capable not only of generating strings of linguistic elements, but also of providing a constituent analysis of the strings, and hence more information than finite-state grammars.

诺姆·乔姆斯基在其《句法结构》（1957）一书中讨论的一类语法，作为例子来说明一种生成机制。短语结构语法包含的规则（PS-规则）不仅能生成语言成分语符列，还能对语符列提供组构成分分析，因而比有限状态语法能提供更多的信息。
