Extension (semantics) In any of several fields of study that treat the use of signs — for example, in linguistics, logic, mathematics, semantics, semiotics, and philosophy of language — the extension of a concept, idea, or sign consists of the things to which it applies, in contrast with its comprehension or intension, which consists very ...
The extension of a sentence can be interpreted as its truth value while its intension is the set of all possible worlds in which it is true. [123] Truth-conditional semantics is closely related to verificationist theories , which introduce the additional idea that there should be some kind of verification procedure to assess whether a sentence ...
For example, the sentences "Pat loves Chris" and "Chris is loved by Pat" mean roughly the same thing and use similar words. Some linguists, Chomsky in particular, have tried to account for this similarity by positing that these two sentences are distinct surface forms that derive from a common (or very similar [ 1 ] ) deep structure.
In-text attribution is the attribution inside a sentence of material to its source, in addition to an inline citation after the sentence. In-text attribution may need to be used with direct speech (a source's words between quotation marks or as a block quotation ); indirect speech (a source's words modified without quotation marks); and close ...
Lexical semantics also explores whether the meaning of a lexical unit is established by looking at its neighbourhood in the semantic network, [7] (words it occurs with in natural sentences), or whether the meaning is already locally contained in the lexical unit. In English, WordNet is an example of a semantic
Second-order logic. In logic and mathematics, second-order logic is an extension of first-order logic, which itself is an extension of propositional logic. [ 1] Second-order logic is in turn extended by higher-order logic and type theory . First-order logic quantifies only variables that range over individuals (elements of the domain of ...
The reference of a sentence is its truth value, whereas its sense is the thought that it expresses. [ 1] Frege justified the distinction in a number of ways. Sense is something possessed by a name, whether or not it has a reference. For example, the name "Odysseus" is intelligible, and therefore has a sense, even though there is no individual ...
An extensional definition gives meaning to a term by specifying its extension, that is, every object that falls under the definition of the term in question.. Forget example, an extensional definition of the term "nation of the world" might be given by listing all of the nations of the world, or by giving some other means of recognizing the members of the corresponding class.
