These all only support projective trees so far, wherein edges do not cross given the token ordering from the sentence. For non-projective trees, Nivre in 2009 modified arc-standard transition-based parsing to add the operation Swap (swap the top two tokens on the stack, assuming the formulation where the next token is always added to the stack ...
The predicate calculus goes a step further than the propositional calculus to an "analysis of the inner structure of propositions" [4] It breaks a simple sentence down into two parts (i) its subject (the object (singular or plural) of discourse) and (ii) a predicate (a verb or possibly verb-clause that asserts a quality or attribute of the object(s)).
The difference between an Oxford comma and a regular comma is that an Oxford comma refers to the final comma in a series that would come before the last conjunction of a sentence.
In an ordinary English clause, the subject is normally the same as the topic/theme (example 1), even in the passive voice (where the subject is a patient, not an agent: example 2): The dog bit the little girl. The little girl was bitten by the dog. These clauses have different topics: the first is about the dog, and the second about the little ...
The word problem for an algebra is then to determine, given two expressions (words) involving the generators and operations, whether they represent the same element of the algebra modulo the identities. The word problems for groups and semigroups can be phrased as word problems for algebras. [1]
Word problem from the Līlāvatī (12th century), with its English translation and solution. In science education, a word problem is a mathematical exercise (such as in a textbook, worksheet, or exam) where significant background information on the problem is presented in ordinary language rather than in mathematical notation.
Scrambling is a syntactic phenomenon wherein sentences can be formulated using a variety of different word orders without a substantial change in meaning. Instead the reordering of words, from their canonical position, has consequences on their contribution to the discourse (i.e., the information's "newness" to the conversation).
This is a comma before "and" or "or" at the end of a series, regardless of whether it is needed for clarification purposes. For example: X, Y, and Z (with an Oxford comma) X, Y and Z (without an Oxford comma) Wikipedia has no preference between the two styles, but requests that the chosen style be used consistently within an article.
