Syntactic Structures is an important work in linguistics by American linguist Noam Chomsky, originally published in 1957.A short monograph of about a hundred pages, it is recognized as one of the most significant and influential linguistic studies of the 20th century.
If we illustrate the structure of the sentence above in accordance with the X-bar schema, we obtain the structure in Figure 2 [FN 1] [FN 2] [FN 3].. Figure 2. Under the X-bar theory, a node necessarily divides into two branches because of the binarity principle.
A sentence, in turn, is formed as a sequence of symbols, beginning with a designated non-terminal symbol and culminating in a terminal string. Every terminal node is part of a constituent, as constituents form the interconnected structure leading from the root to the smallest, indivisible unit of the tree.
In the past, feature-based classifiers were also common, with features chosen from part-of-speech tags, sentence position, morphological information, etc. This is an O ( n ) {\displaystyle O(n)} greedy algorithm, so it does not guarantee the best possible parse or even a necessarily valid parse, but it is efficient.

In the first b-sentence, the constituent which story likewise serves as the object of the verb, but appears at the beginning of the sentence rather than in its canonical position following the verb. Movement-based analyses explain this fact by positing that the constituent is base-generated in its canonical position but is moved to the ...
This sentence was constructed by Noam Chomsky as an illustration that phrase structure rules are capable of generating syntactically correct but semantically incorrect sentences. Phrase structure rules break sentences down into their constituent parts. These constituents are often represented as tree structures (dendrograms). The tree for ...
This means if the sentence read "you handed Courtney the notebook", the participants were faster to push the button that was farther away from them when this button meant the sentence was logical. The depicted motion in these sentences affected the amount of time required to understand the sentences that described the motion that is in the same ...
Treebanks can be created completely manually, where linguists annotate each sentence with syntactic structure, or semi-automatically, where a parser assigns some syntactic structure which linguists then check and, if necessary, correct. In practice, fully checking and completing the parsing of natural language corpora is a labour-intensive ...
