Principle Of Compositionality
In semantics, mathematical logic and related disciplines, the principle of compositionality is the principle that the meaning of a complex expression is determined by the meanings of its constituent expressions and the rules used to combine them. This principle is also called Frege's principle, because Gottlob Frege is widely credited for the first modern formulation of it. The principle was never explicitly stated by Frege, and it was arguably already assumed by George Boole decades before Frege's work. The principle of compositionality is highly debated in linguistics, and among its most challenging problems there are the issues of contextuality, the non-compositionality of idiomatic expressions, and the non-compositionality of quotations. History Discussion of compositionality started to appear at the beginning of the 19th century, during which it was debated whether what was most fundamental in language was compositionality or contextuality, and compositionality was usuall ...

Semantics
Semantics (from grc, σημαντικός ''sēmantikós'', "significant") is the study of reference, meaning, or truth. The term can be used to refer to subfields of several distinct disciplines, including philosophy, linguistics and computer science. History In English, the study of meaning in language has been known by many names that involve the Ancient Greek word (''sema'', "sign, mark, token"). In 1690, a Greek rendering of the term ''semiotics'', the interpretation of signs and symbols, finds an early allusion in John Locke's ''An Essay Concerning Human Understanding'': The third Branch may be called [''simeiotikí'', "semiotics"], or the Doctrine of Signs, the most usual whereof being words, it is aptly enough termed also , Logick. In 1831, the term is suggested for the third branch of division of knowledge akin to Locke; the "signs of our knowledge". In 1857, the term '' semasiology'' (borrowed from German ''Semasiologie'') is attested in Josiah W. Gibb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Logical Truth
Logical truth is one of the most fundamental concepts in logic. Broadly speaking, a logical truth is a statement which is true regardless of the truth or falsity of its constituent propositions. In other words, a logical truth is a statement which is not only true, but one which is true under all interpretations of its logical components (other than its logical constants). Thus, logical truths such as "if p, then p" can be considered tautologies. Logical truths are thought to be the simplest case of statements which are analytically true (or in other words, true by definition). All of philosophical logic can be thought of as providing accounts of the nature of logical truth, as well as logical consequence. Logical truths are generally considered to be ''necessarily true''. This is to say that they are such that no situation could arise in which they could fail to be true. The view that logical statements are necessarily true is sometimes treated as equivalent to saying that l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Semantics (computer Science)
In programming language theory, semantics is the rigorous mathematical study of the meaning of programming languages. Semantics assigns computational meaning to valid strings in a programming language syntax. Semantics describes the processes a computer follows when executing a program in that specific language. This can be shown by describing the relationship between the input and output of a program, or an explanation of how the program will be executed on a certain platform, hence creating a model of computation. History In 1967, Robert W. Floyd publishes the paper ''Assigning meanings to programs''; his chief aim is "a rigorous standard for proofs about computer programs, including proofs of correctness, equivalence, and termination". Floyd further writes: A semantic definition of a programming language, in our approach, is founded on a syntactic definition. It must specify which of the phrases in a syntactically correct program represent commands, and what condi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Componential Analysis
Componential analysis (feature analysis or contrast analysis) is the analysis of words through structured sets of semantic features, which are given as "present", "absent" or "indifferent with reference to feature". The method thus departs from the principle of compositionality. Componential analysis is a method typical of structural semantics which analyzes the components of a word's meaning. Thus, it reveals the culturally important features by which speakers of the language distinguish different words in a semantic field or domain (Ottenheimer, 2006, p. 20). Examples ''man'' = MALE MATUREor ''woman'' = MALE MATUREor ''boy'' = MALE MATUREor ''girl'' = MALE MATUREor ''child'' = /– MALE MATURE In other words, the word ''girl'' can have three basic factors (or semantic properties): human, young, and female. Another example, being edible is an important factor by which plants may be distinguished from one another (Ottenheimer, 2006, p. 20). ...

Context Principle
In the philosophy of language, the context principle is a form of semantic holism holding that a philosopher should "never ... ask for the meaning of a word in isolation, but only in the context of a proposition" (Frege 884/1980x). Analysis The context principle is one of Gottlob Frege's "three fundamental principles" for philosophical analysis, first discussed in his Introduction to ''The Foundations of Arithmetic'' (''Grundlagen der Arithmetik'', 1884). Frege argued that many philosophical errors, especially those related to psychologism in the philosophy of logic and philosophy of mathematics, could be avoided by adhering carefully to the context principle. The view of meaning expressed by the context principle is sometimes called semantic contextualism. This view need not be contrasted with the view that the meanings of words or expressions can (or must) be determined prior to, and independently of, the meanings of the propositions in which they occur, which is often referred t ...

Sarcasm
Sarcasm is the caustic use of words, often in a humorous way, to mock someone or something. Sarcasm may employ ambivalence, although it is not necessarily ironic. Most noticeable in spoken word, sarcasm is mainly distinguished by the inflection with which it is spoken or, with an undercurrent of irony, by the extreme disproportion of the comment to the situation, and is largely context-dependent. Etymology The word comes from the Greek σαρκασμός (''sarkasmós'') which is taken from σαρκάζειν (''sarkázein'') meaning "to tear flesh, bite the lip in rage, sneer".Oxford English Dictionary It is first recorded in English in 1579, in an annotation to '' The Shepheardes Calender'' by Edmund Spenser: However, the word ''sarcastic'', meaning "Characterized by or involving sarcasm; given to the use of sarcasm; bitterly cutting or caustic", doesn't appear until 1695. Usage In its entry on irony, Dictionary.com describes sarcasm thus: In sarcasm, ridicule or mo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Subcategorization
In linguistics, subcategorization denotes the ability/necessity for lexical items (usually verbs) to require/allow the presence and types of the syntactic arguments with which they co-occur. The notion of subcategorization is similar to the notion of valency, although the two concepts (subcategorization and valency) stem from different traditions in the study of syntax and grammar. Argument structure Argument structure is the list of selected arguments associated with a lexical category, such as a verb (SKS, 2015). When every predicate, otherwise known as a verb, is used, it selects a specific set of arguments that need to be fulfilled to create a well-formed sentence (Kroger, 2005). These are arguments such as AGENT, PATIENT, EXPERIENCER, THEME, RECIPIENT, and STIMULUS. To illustrate this, the sentence ''The adults asked if the cats would pee on the sofa'', has been broken down into its semantic roles and argument selections below. It is necessary to understand the fundame ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ray Jackendoff
Ray Jackendoff (born January 23, 1945) is an American linguist. He is professor of philosophy, Seth Merrin Chair in the Humanities and, with Daniel Dennett, co-director of the Center for Cognitive Studies at Tufts University. He has always straddled the boundary between generative linguistics and cognitive linguistics, committed to both the existence of an innate universal grammar (an important thesis of generative linguistics) and to giving an account of language that is consistent with the current understanding of the human mind and cognition (the main purpose of cognitive linguistics). Jackendoff's research deals with the semantics of natural language, its bearing on the formal structure of cognition, and its lexical and syntactic expression. He has conducted extensive research on the relationship between conscious awareness and the computational theory of mind, on syntactic theory, and, with Fred Lerdahl, on musical cognition, culminating in their generative theory ...

Logical Metonymy
Logic is the study of correct reasoning. It includes both formal and informal logic. Formal logic is the science of deductively valid inferences or of logical truths. It is a formal science investigating how conclusions follow from premises in a topic-neutral way. When used as a countable noun, the term "a logic" refers to a logical formal system that articulates a proof system. Formal logic contrasts with informal logic, which is associated with informal fallacies, critical thinking, and argumentation theory. While there is no general agreement on how formal and informal logic are to be distinguished, one prominent approach associates their difference with whether the studied arguments are expressed in formal or informal languages. Logic plays a central role in multiple fields, such as philosophy, mathematics, computer science, and linguistics. Logic studies arguments, which consist of a set of premises together with a conclusion. Premises and conclusions are usually ...

Semantic Memory
Semantic memory refers to general world knowledge that humans have accumulated throughout their lives. This general knowledge (word meanings, concepts, facts, and ideas) is intertwined in experience and dependent on culture. We can learn about new concepts by applying our knowledge learned from things in the past. Semantic memory is distinct from episodic memory, which is our memory of experiences and specific events that occur during our lives, from which we can recreate at any given point. For instance, semantic memory might contain information about what a cat is, whereas episodic memory might contain a specific memory of petting a particular cat. Semantic memory and episodic memory are both types of explicit memory (or declarative memory), that is, memory of facts or events that can be consciously recalled and "declared". The counterpart to declarative or explicit memory is nondeclarative memory or implicit memory. History The idea of semantic memory was first intro ...
