A grammar that uses phrase structure rules is a type of phrase structure grammar. Phrase structure rules as they are commonly employed operate according to the constituency relation, and a grammar that employs phrase structure rules is therefore a constituency grammar ; as such, it stands in contrast to dependency grammars , which are based on ...
When presented with phrase-structure violations in Jabberwocky sentences, however, preschoolers demonstrate activity analogous to a N400, typically associated with the extraction of meaning from words in adults, along with a diminished P600. This implies that semantics plays a role in syntactic processing in children and provides ...
The term phrase structure grammar was originally introduced by Noam Chomsky as the term for grammar studied previously by Emil Post and Axel Thue (Post canonical systems). Some authors, however, reserve the term for more restricted grammars in the Chomsky hierarchy : context-sensitive grammars or context-free grammars .
A semantic treebank is a collection of natural language sentences annotated with a meaning representation. These resources use a formal representation of each sentence's semantic structure . Semantic treebanks vary in the depth of their semantic representation.
In generative grammar and related approaches, the logical form (LF) of a linguistic expression is the variant of its syntactic structure which undergoes semantic interpretation. It is distinguished from phonetic form , the structure which corresponds to a sentence's pronunciation.
This is noise that is often caused by the sender (also known as either the encoder or the source). [10] This type of noise occurs when grammar or technical language is used that the receiver (the decoder) cannot understand, or cannot understand it clearly. It occurs when the sender of the message uses a word or a phrase that we don't know the ...
Generalized phrase structure grammar (GPSG) is a framework for describing the syntax and semantics of natural languages. It is a type of constraint-based phrase structure grammar . Constraint based grammars are based around defining certain syntactic processes as ungrammatical for a given language and assuming everything not thus dismissed is ...
