semantics

A semantic link is a typed link where the element itself provides meaningful information about the link (semantics). For instance, in XML, you might have a BookTitle element <BookTitle isbn="0812511816"/>. You can use the semantic information provided in the element (the ISBN number) to create a link from this element to an online bookseller. The link describes some external relationship or issue. An example of a semantic link would be (any syntax expressing) "A is-mother-of B". Some other relations like "B is-child-of A" may be implied by it.

In philosophical semantics or philosophy of language, the extension of a concept or expression is the set of things it extends to, or applies to, if it is the sort of concept or expression that a single object by itself can satisfy. (Concepts and expressions of this sort are monadic or "one-place" concepts and expressions.) The extension of a whole statement, as opposed to a word or phrase, is defined (by convention) as its truth-value. So the extension of "Lassie is famous" is the truth- ...

Semantics is a subfield of linguistics that is traditionally defined as the study of meaning of (parts of) words, phrases, sentences, and texts. Semantics can be approached from a theoretical as well as an empirical (for example psycholinguistic and neuroscientific) point of view. The decompositional perspective towards meaning holds that the meaning of words can be analyzed by defining meaning atoms or primitives, which establish a language of thought. An area of study is the meaning of compounds, another is the study o ...

Kripke semantics for the intuitionistic logic follows the same principles as the semantics of modal logic, but it uses a different definition of satisfaction. An intuitionistic Kripke model is a triple <W,≤,>, where <W,≤> is a transitive and reflexive Kripke frame (i.e., the accessibility relation is a preorder), and satisfies the following conditions: if p is a propositional variable, w ≤ u, and w p, then u p ( ...

The Semantic Web is comprised of the standards and tools of XML, XML Schema, RDF, RDF Schema and OWL. The OWL Web Ontology Language Overview describes the function and relationship of each of these components of the Semantic Web: XML provides a surface syntax for structured documents, but imposes no semantic constraints on the meaning of these documents. XML Schema is a language for restricting the structure of XML documents. RDF is a simple data model for referring to objects ("resources") and how they are rel ...

Today, much of the world wide web is stored as Hypertext Markup Language. Search engines are severely hampered by their inability to understand the meaning of published web pages. These limitations have created a movement called the Semantic web. In the past, many organizations that created custom database application used isolated teams of developers that did not formally publish their data definitions. These teams frequently used internal data definitions that were incompatible with other computer systems. This made Enterprise Appli ...

In mathematics, the extension of a mathematical concept is the set that is specified by that concept. For example, the extension of a function is a set of ordered pairs that pair up the arguments and values of the function; in other words, the function's graph. The extension of an object in abstract algebra, such as a group, is the underlying set of the object. The extension of a set is, of course, the set itself. That a set can capture the notion of the extension of anything is the idea behin ...

The four main types of semantic change are extension, narrowing, amelioration, and pejoration. However, there are many other types as well. Extension is where a word widens its meaning. For example, virtue used to just be a man's quality. In contemporary society, it applies to women as well. Narrowing is where a word's meaning becomes more specialised. For example, in old English, meat, (or rather mete), referred to food in general. Amelioration is ...

The denotational theory of computational system semantics is concerned with finding mathematical objects that represent what systems do. The theory makes use of a computational mathematical domains. Examples of such computational domains are partial functions and Actor event diagram scenarios. The relationship x≤y means that x can computationally evolve to y. If the denotations are partial functions, for example, f≤g may mean that f agrees with g on all values for which fSee also:

For our purposes, the language of modal logic consists of propositional variables, the reader's favorite complete set of Boolean connectives (such as {→,¬} or {∨,∧,¬}), and the modal operator (“necessity”). The dual modal operator (“possibility”) is defined as an abbreviation: . See the page on modal logic for more background. Kripke semantics - Basic definitions. A Kripke frame or modal frame is a pair <W,R>, where W is a non-empty set, and RSee also:

Korzybski's most well-known student was S. I. Hayakawa, who wrote Language In Thought And Action (1941), which became an alternative Book-of-the-Month Club selection. An earlier and less influential book in 1938 was The Tyranny of Words, by Stuart Chase. A current book is Drive Yourself Sane, by Susan and Bruce Kodish, published in 2000. Two major groups were formed in the United States to promote the system: the Institute of General Semantics, in 1938, and the International Society for General Semantics, in 1943. ...

In semantics, reference is generally construed as the relation between nouns or pronouns and objects that are named by them. Hence the word "John" refers to John; the word "it" refers to some previously specified object. The objects referred to are called the "referents" of the word. Sometimes the word-object relation is called "denotation"; the referent denotes the object. Reference is not in general the same as meaning, as words can often be meaningful without having a referent. Fictional and mythological names such as ...

As mentioned earlier, the field was initially developed by Christopher Strachey and Dana Scott in the 1960s and then Joe Stoy in the 1970s at the Programming Research Group, part of the Oxford University Computing Laboratory. Montague grammar is a form of denotational semantics for idealized fragments of English. According to Clinger [1981], Plotkin's original power domain construction was simplified in [Smyth 1978] which remains the standard introduction to the subject. A number of nondeterministic programming lan ...

Most people are capable of using the web to, say, find the Swedish word for "car", renew a library book, or find the cheapest DVD and buy it. But if you ask a computer to do the same thing, it wouldn't know where to start. That is because web pages are designed to be read by humans, not machines. The Semantic Web is a project aimed to make web pages understandable by computers, so that they can search websites and perform actions in a standardized way. The potential benefits are that computers can harness the enormous network of infor ...

In linguistics and semantics contrast is a relationship between two discourse segments. Contrast is often overtly marked by contrastive markers like but or however, such as in the following examples: (1) It's raining but I am taking an umbrella. (2) We will be giving a party for our new students. We won't, however, be serving drinks. In (1) the first clause, It's raining implies that the speaker will get wet, while the second clause I am taking an umbrella implies that the speaker ...

The concept of full abstraction is concerned with whether the denotational semantics for a program is an exact match for its operational semantics. Key properties of full abstraction are: Abstractness: The denotational semantics must be formalised using mathematical structures that are independent of the representation and operational semantics of the programming language; Soundness: All observably distinct programs have distinct denotations; Completeness: Any two programs wi ...

There is some ambiguity among English speaking Muslims on the use of Tawrat versus Torah. The Arabic of the Qur'an and hadith have only one word, Tawrat. Torah is natively a Hebrew word. Generally, in English as well, they are used interchangeably. However, some Muslims prefer to reserve Tawrat to refer only to the original revelation of Allah to Musa which was later corrupted. They use Torah to refer to the current, corrupted text. Ideally, this usage is preferred because the corrupted and uncorrupted texts are obviously very different and bo ...

Kripke semantics does not originate with Kripke, but instead the idea of giving semantics in the style given above, that is based on valuations made that are relative to nodes, predates Kripke by a long margin: Carnap seems to have been the first to have the idea that one can give a possible world semantics for the modalities of necessity and possibility by means of giving the valuation function a parameter that ranges over Leibnizian possible worlds. Bayart develops this idea further, but neither gave recursive definitio ...
