phrase structure rule造句

• Phrase structure rules break sentences down into their constituent parts.
• The constituency tree on the left could be generated by phrase structure rules.
• Instead of " phrase structure rules"
• The Projection Principle therefore obviates the need for phrase structure rules in the generative component.
• Phrase markers are generated by applying phrase structure rules, and themselves are subject to further transformational rules.
• The phrase structure rules of context free grammar, for instance, were generating sentence structure top down.
• Phrase structure rules and the tree structures that are associated with them are a form of immediate constituent analysis.
• In the Extended Standard Theory and government and binding theory, GTs were abandoned in favor of recursive phrase structure rules.
• This sentence was constructed by Noam Chomsky as an illustration that phrase structure rules are capable of generating syntactically correct but semantically incorrect sentences.
• In Generalized Phrase Structure Grammar ( GPSG ), many of the phrase structure rules generate the class of verbs with a particular valence.
• In terms of phrase structure rules, phrasal categories can occur to the left of the arrow while lexical categories cannot, e . g.
• According to more recent theories, phrase structures are not generated by phrase structure rules, but are'projected'from the lexical entries.
• However, phrase structure rules are supposed to be universal, therefore this new rule would also allow us to generate " I happy " in English.
• The dependency tree on the right could not, in contrast, be generated by phrase structure rules ( at least not as they are commonly interpreted ).
• Among the more technical innovations are the use of recursive phrase structure rules and the introduction of syntactic features in lexical entries to address the issue of subcategorization.
• Particularly in early incarnations, transformational syntax adopted the view that phrase structure grammar must be enriched by a transformational grammar, with syntactic rules or syntactic operations that alter the base structures created by phrase structure rules.
• In transformational grammar, systems of phrase structure rules are supplemented by transformation rules, which act on an existing syntactic structure to produce a new one ( performing such operations as negation, passivization, etc . ).
• These transformations are not strictly required for generation, as the sentences they produce could be generated by a suitably expanded system of phrase structure rules alone, but transformations provide greater economy and enable significant relations between sentences to be reflected in the grammar.
• For example, a typical phrase structure rule might say S-> NP \; VP, indicating that an S-node dominates an NP-node and a VP-node, and that the NP precedes the VP in the surface string.
• Beginning with the sentence symbol S, and applying the phrase structure rules successively, finally applying replacement rules to substitute actual words for the abstract symbols, it is possible to generate many proper sentences of English ( or whichever language the rules are specified for ).
