Lexical Item
In lexicography, a lexical item is a single word, a part of a word, or a chain of words (catena (linguistics), catena) that forms the basic elements of a language's lexicon (≈ vocabulary). Examples are ''cat'', ''traffic light'', ''take care of'', ''by the way'', and ''it's raining cats and dogs''. Lexical items can be generally understood to convey a single meaning, much as a lexeme, but are not limited to single words. Lexical items are like seme (semantics), semes in that they are "natural units" translating between languages, or in learning a new language. In this last sense, it is sometimes said that language consists of grammaticalized lexis, and not lexicalized grammar. The entire store of lexical items in a language is called its lexis (linguistics), lexis. Lexical items composed of more than one word are also sometimes called ''lexical chunks'', ''gambits'', ''lexical phrases'', ''lexicalized stems'', or ''speech formulae''. The term ''polyword listemes'' is also ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lexicography
Lexicography is the study of lexicons and the art of compiling dictionaries. It is divided into two separate academic disciplines: * Practical lexicography is the art or craft of compiling, writing and editing dictionaries. * Theoretical lexicography is the scholarly study of semantic, orthography, orthographic, syntagma (linguistics), syntagmatic and paradigmatic features of lexemes of the lexicon (vocabulary) of a language, developing theories of dictionary components and structures linking the data in dictionaries, the needs for information by users in specific types of situations, and how users may best access the data incorporated in printed and Electronic dictionary, electronic dictionaries. This is sometimes referred to as "metalexicography". There is some disagreement on the definition of lexicology, as distinct from lexicography. Some use "lexicology" as a synonym for theoretical lexicography; others use it to mean a branch of linguistics pertaining to the inventor ...

Constituent (linguistics)
In syntactic analysis, a constituent is a word or a group of words that function as a single unit within a hierarchical structure. The constituent structure of sentences is identified using ''tests for constituents''. These tests apply to a portion of a sentence, and the results provide evidence about the constituent structure of the sentence. Many constituents are phrases. A phrase is a sequence of one or more words (in some theories two or more) built around a head lexical item and working as a unit within a sentence. A word sequence is shown to be a phrase/constituent if it exhibits one or more of the behaviors discussed below. The analysis of constituent structure is associated mainly with phrase structure grammars, although dependency grammars also allow sentence structure to be broken down into constituent parts. Tests for constituents in English Tests for constituents are diagnostics used to identify sentence structure. There are numerous tests for constituents that are ...

Lexical Semantics
Lexical semantics (also known as lexicosemantics), as a subfield of linguistics, linguistic semantics, is the study of word meanings.Pustejovsky, J. (2005) Lexical Semantics: Overview' in Encyclopedia of Language and Linguistics, second edition, Volumes 1-14Taylor, J. (2017) Lexical Semantics'. In B. Dancygier (Ed.), The Cambridge Handbook of Cognitive Linguistics (Cambridge Handbooks in Language and Linguistics, pp. 246-261). Cambridge: Cambridge University Press. It includes the study of how words structure their meaning, how they act in grammar and Principle of compositionality, compositionality, and the relationships between the distinct senses and uses of a word. The units of analysis in lexical semantics are lexical units which include not only words but also sub-words or sub-units such as affixes and even compound words and phrases. Lexical units include the catalogue of words in a language, the lexicon. Lexical semantics looks at how the meaning of the lexical units correl ...

Set Phrase
A phraseme, also called a set phrase, fixed expression, multiword expression (in computational linguistics), or idiom, is a multi-word or multi-morphemic utterance whose components include at least one that is selectionally constrained or restricted by linguistic convention such that it is not freely chosen. In the most extreme cases, there are expressions such as ''X kicks the bucket'' ≈ ‘person X dies of natural causes, the speaker being flippant about X’s demise’ where the unit is selected as a whole to express a meaning that bears little or no relation to the meanings of its parts. All of the words in this expression are chosen restrictedly, as part of a chunk. At the other extreme, there are collocations such as ''stark naked'', ''hearty laugh'', or ''infinite patience'' where one of the words is chosen freely (''naked'', ''laugh'', and ''patience'', respectively) based on the meaning the speaker wishes to express while the choice of the other (intensifying) word (''sta ...

Outline Of Linguistics
The following outline is provided as an overview and topical guide to linguistics: Linguistics is the scientific study of language. Someone who engages in this study is called a linguist. Linguistics can be theoretical or applied. Branches of linguistics Subfields of linguistics * General linguistics ** Phonetics – the study of the speech faculty ** Phonology – the usage of vocalized sounds and systems of sounds to form language ** Morphology – the property of sound and meaning dynamics in language ** Syntax – the property of grammar that governs sentence structure ** Semantics – the study of meaning as encoded in grammar ** Pragmatics – the study of how context contributes to meaning ** Graphemics – the study of writing systems *** Graphetics – the study of writing shapes as assigned to sounds or ideas * Theoretical linguistics – the study of language as an abstract object ** Generative linguistics – an approach which seeks to ground grammar in ...

Lexical Chain
The sequence between semantic related ordered words is classified as a lexical chain. A lexical chain is a sequence of related words in writing, spanning narrow (adjacent words or sentences) or wide context windows (an entire text). A lexical chain is independent of the grammatical structure of the text and in effect it is a list of words that captures a portion of the cohesive structure of the text. A lexical chain can provide a context for the resolution of an ambiguous term and enable disambiguation of concepts that the term represents. Examples include: * Rome → capital → city → inhabitant * Wikipedia → resource → web About Morris and Hirst introduce the term ''lexical chain'' as an expansion of ''lexical cohesion.'' A text in which many of its sentences are semantically connected often produces a certain degree of continuity in its ideas, providing good cohesion among its sentences. The definition used for lexical cohesion states that coherence is a result of c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dependency Grammar
Dependency grammar (DG) is a class of modern Grammar, grammatical theories that are all based on the dependency relation (as opposed to the ''constituency relation'' of Phrase structure grammar, phrase structure) and that can be traced back primarily to the work of Lucien Tesnière. Dependency is the notion that linguistic units, e.g. words, are connected to each other by directed links. The (finite) verb is taken to be the structural center of clause structure. All other syntactic units (words) are either directly or indirectly connected to the verb in terms of the directed links, which are called ''dependencies''. Dependency grammar differs from phrase structure grammar in that while it can identify phrases it tends to overlook phrasal nodes. A dependency structure is determined by the relation between a word (a Head (linguistics), head) and its dependents. Dependency structures are flatter than phrase structures in part because they lack a finite verb, finite verb phrase constit ...

Catena (linguistics)
In linguistics, a catena (English pronunciation: , plural catenas or catenae; from Latin for "chain") is a unit of syntax and morphology, closely associated with dependency grammars. It is a more flexible and inclusive unit than the constituent and its proponents therefore consider it to be better suited than the constituent to serve as the fundamental unit of syntactic and morphosyntactic analysis. The catena has served as the basis for the analysis of a number of phenomena of syntax, such as idiosyncratic meaning, ellipsis mechanisms (e.g. gapping, stripping, VP-ellipsis, pseudogapping, sluicing, answer ellipsis, comparative deletion), predicate-argument structures, and discontinuities (topicalization, wh-fronting, scrambling, extraposition, etc.). The catena concept has also been taken as the basis for a theory of morphosyntax, i.e. for the extension of dependencies into words; dependencies are acknowledged between the morphs that constitute words. While the catena concep ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Semantic Relation
Contemporary ontologies share many structural similarities, regardless of the ontology language in which they are expressed. Most ontologies describe individuals (instances), classes (concepts), attributes, and relations. List Common components of ontologies include: ;Individuals: instances or objects (the basic or "ground level" objects; the tokens). ;Classes: sets, collections, concepts, types of objects, or kinds of things.See Class (set theory), Class (computer science), and Class (philosophy), each of which is relevant but not identical to the notion of a "class" here. ; Attributes: aspects, properties, features, characteristics, or parameters that individuals (and classes and relations) can have. ; Relations: ways in which classes and individuals can be related to one another. Relations can carry attributes that specify the relation further. ;Function terms: complex structures formed from certain relations that can be used in place of an individual term in a statement. ...
