Semantic Scholar. Semantic Scholar is a research tool for scientific literature powered by artificial intelligence. It is developed at the Allen Institute for AI and was publicly released in November 2015. [ 2] Semantic Scholar uses modern techniques in natural language processing to support the research process, for example by providing ...
The universal quantifier "for every" in this sentence expresses the idea that the claim "if x is a philosopher, then x is a scholar" holds for all choices of x. The negation of the sentence "For every x , if x is a philosopher, then x is a scholar" is logically equivalent to the sentence "There exists x such that x is a philosopher and x is not ...
Semantics is the study of linguistic meaning. It examines what meaning is, how words get their meaning, and how the meaning of a complex expression depends on its parts. Part of this process involves the distinction between sense and reference. Sense is given by the ideas and concepts associated with an expression while reference is the object ...
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 ...
The semantics of logic refers to the approaches that logicians have introduced to understand and determine that part of meaning in which they are interested; the logician traditionally is not interested in the sentence as uttered but in the proposition, an idealised sentence suitable for logical manipulation. [citation needed] Until the advent ...
t. e. The theory of descriptions is the philosopher Bertrand Russell 's most significant contribution to the philosophy of language. It is also known as Russell's theory of descriptions (commonly abbreviated as RTD ). In short, Russell argued that the syntactic form of descriptions (phrases that took the form of "The aardvark" and "An aardvark ...
In traditional semantics, the meaning of a sentence is the situation it represents, and the situation can be described in terms of the possible world that it would be true of. Moreover, sentence meanings may be dependent upon propositional attitudes : those features that are relative to someone's beliefs, desires, and mental states.
In semantics and pragmatics, a truth condition is the condition under which a sentence is true. For example, "It is snowing in Nebraska " is true precisely when it is snowing in Nebraska. Truth conditions of a sentence do not necessarily reflect current reality. They are merely the conditions under which the statement would be true.
