Diathesis Alternation
In linguistics, diathesis alternation or verb alternationLevin, B. (1993) English Verb Classes and Alternations: A Preliminary Investigation, University of Chicago Press, Chicago, IL occurs when the same verb can be used in different subcategorization frames or with different valency, as in "Fred ate the pizza" (where ''ate'' is transitive, with object "the pizza") vs. "Fred ate" (where ''ate'' is intransitive, with no object). The two usages usually have a slight difference in meaning. Using a single verb, one can also change the position of a phrase's arguments which may or may not change the sentence's meaning as well. It is a hard problem for theoretical linguistics how to encode constraints on the diathesis alternation of a specific verb to a lexicon. It is also claimed that the manner in which verbs undergo diathesis alternation can be used to identify the semantic class they belong to e.g. in a machine learning task. Examples * Fred ate the pizza vs. Fred ate * Mary bro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Linguistics
Linguistics is the scientific study of human language. It is called a scientific study because it entails a comprehensive, systematic, objective, and precise analysis of all aspects of language, particularly its nature and structure. Linguistics is concerned with both the cognitive and social aspects of language. It is considered a scientific field as well as an academic discipline; it has been classified as a social science, natural science, cognitive science,Thagard, PaulCognitive Science, The Stanford Encyclopedia of Philosophy (Fall 2008 Edition), Edward N. Zalta (ed.). or part of the humanities. Traditional areas of linguistic analysis correspond to phenomena found in human linguistic systems, such as syntax (rules governing the structure of sentences); semantics (meaning); morphology (structure of words); phonetics (speech sounds and equivalent gestures in sign languages); phonology (the abstract sound system of a particular language); and pragmatics (how social con ...

Subcategorization Frame
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 fundam ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Valency (linguistics)
In linguistics, valency or valence is the number and type of arguments controlled by a predicate, content verbs being typical predicates. Valency is related, though not identical, to subcategorization and transitivity, which count only object arguments – valency counts all arguments, including the subject. The linguistic meaning of valency derives from the definition of valency in chemistry. The valency metaphor appeared first in linguistics in Charles Sanders Peirce's essay "The Logic of Relatives" in 1897, and it then surfaced in the works of a number of linguists decades later in the late 1940s and 1950s. Lucien Tesnière is credited most with having established the valency concept in linguistics. A major authority on the valency of the English verbs is Allerton (1982), who made the important distinction between semantic and syntactic valency. Types There are several types of valency: #impersonal (= avalent) ''it rains'' #intransitive (monovalent/monadic) ''she s ...

Theoretical Linguistics
Theoretical linguistics is a term in linguistics which, like the related term general linguistics, can be understood in different ways. Both can be taken as a reference to theory of language, or the branch of linguistics which inquires into the nature of language and seeks to answer fundamental questions as to what language is, or what the common ground of all languages is. The goal of theoretical linguistics can also be the construction of a general theoretical framework for the description of language. Another use of the term depends on the organisation of linguistics into different sub-fields. The term theoretical linguistics is commonly juxtaposed with applied linguistics. This perspective implies that the aspiring language professional, e.g. a teacher student, must first learn the ''theory'' i.e. properties of the linguistic system, or what Ferdinand de Saussure called ''internal linguistics''. This is followed by ''practice,'' or studies in the applied field. The dichotomy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lexicon
A lexicon is the vocabulary of a language or branch of knowledge (such as nautical or medical). In linguistics, a lexicon is a language's inventory of lexemes. The word ''lexicon'' derives from Koine Greek language, Greek word (), neuter of () meaning 'of or for words'. Linguistic theories generally regard human languages as consisting of two parts: a lexicon, essentially a catalogue of a language's words (its wordstock); and a grammar, a system of rules which allow for the combination of those words into meaningful sentences. The lexicon is also thought to include bound morphemes, which cannot stand alone as words (such as most affixes). In some analyses, compound words and certain classes of idiomatic expressions, collocations and other phrases are also considered to be part of the lexicon. Dictionary, Dictionaries are lists of the lexicon, in alphabetical order, of a given language; usually, however, bound morphemes are not included. Size and organization Items in the le ...

Semantic Class
A semantic class contains words that share a semantic feature. For example within nouns there are two sub classes, concrete nouns and abstract nouns. The concrete nouns include people, plants, animals, materials and objects while the abstract nouns refer to concepts such as qualities, actions, and processes. According to the nature of the noun, they are categorized into different semantic classes. Semantic classes may intersect. The intersection of ''female'' and ''young'' can be ''girl''. See also * Semantic property * Categorization Categorization is the ability and activity of recognizing shared features or similarities between the elements of the experience of the world (such as objects, events, or ideas), organizing and classifying experience by associating them to a ... * Semantic field References * Semantics {{semantics-stub es:Campo semántico fr:Classe sémantique kk:Семантикалық өріс ru:Семантическое поле ta:ச� ...

Machine Learning
Machine learning (ML) is a field of inquiry devoted to understanding and building methods that 'learn', that is, methods that leverage data to improve performance on some set of tasks. It is seen as a part of artificial intelligence. Machine learning algorithms build a model based on sample data, known as training data, in order to make predictions or decisions without being explicitly programmed to do so. Machine learning algorithms are used in a wide variety of applications, such as in medicine, email filtering, speech recognition, agriculture, and computer vision, where it is difficult or unfeasible to develop conventional algorithms to perform the needed tasks.Hu, J.; Niu, H.; Carrasco, J.; Lennox, B.; Arvin, F.,Voronoi-Based Multi-Robot Autonomous Exploration in Unknown Environments via Deep Reinforcement Learning IEEE Transactions on Vehicular Technology, 2020. A subset of machine learning is closely related to computational statistics, which focuses on making predicti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ambitransitive Verb
An ambitransitive verb is a verb that is both intransitive and transitive.Dixon, R.M.W. & Aikhenvald, Alexendra Y. Changing Valency: Case Studies in Transitivity. Cambridge University Press. This verb may or may not require a direct object. English has many ambitransitive verbs. Examples include ''read'', ''break'', and ''understand'' (e.g., "I read the book", saying what was read, or just "I read all afternoon"). Ambitransitive verbs are common in some languages, and much less so in other languages, where valency tends to be fixed, and there are explicit valency-changing operations (such as passive voice, antipassive voice, applicatives, causatives, etc.). Agentive and patientive Generally speaking, there are two types of ambitransitive verbs, distinguished by the alignment of the semantic roles of their arguments with their syntactic roles. Agentive Agentive (S = A) ambitransitives are those where the single argument of the intransitive (S) is agentive and it corresponds to th ...

Voice (grammar)
In grammar, the voice of a verb describes the relationship between the action (or state) that the verb expresses and the participants identified by its arguments (subject, object, etc.). When the subject is the agent or doer of the action, the verb is in the active voice. When the subject is the patient, target or undergoer of the action, the verb is said to be in the passive voice. When the subject both performs and receives the action expressed by the verb, the verb is in the middle voice. Voice is sometimes called diathesis. The following pair of examples illustrates the contrast between active and passive voice in English. In sentence (1), the verb form ''ate'' is in the active voice, but in sentence (2), the verb form ''was eaten'' is in the passive voice. Independent of voice, ''the cat'' is the Agent (the doer) of the action of eating in both sentences. # ''The cat ate the mouse.'' # ''The mouse was eaten by the cat.'' In a transformation from an active-voice clause to a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dative Shift
In linguistics, dative shift refers to a pattern in which the subcategorization of a verb can take on two alternating forms, the oblique dative form or the double object construction form. In the oblique dative (OD) form, the verb takes a noun phrase (NP) and a dative prepositional phrase (PP), the second of which is not a core argument. : (1) ''John gave'' NP_''a_book''_.html" ;"title="sub>NP ''a book'' ">sub>NP ''a book'' PP.DATIVE_''to_Mary''_.html" ;"title="sub>PP.DATIVE ''to Mary'' ">sub>PP.DATIVE ''to Mary'' In the double object construction (DOC) form the verb takes two noun phrases, both of which are core arguments, with the dative argument preceding the other argument. : (2) ''John gave'' NP.DATIVE_''Mary''_.html" ;"title="sub>NP.DATIVE ''Mary'' ">sub>NP.DATIVE ''Mary'' NP_''a_book''_.html" ;"title="sub>NP ''a book'' ">sub>NP ''a book'' Synonyms used in the literature Terms used in literature on dative shift can vary.

Causative Alternation
In linguistics, causative alternation is a phenomenon in which certain verbs that express a change of state (or a change of degree) can be used transitively or intransitively.Levin, Beth. "Causative Alternation". ''English Verb Classes and Alternations''. Chicago: University Press of Chicago, 1993. 26–27. Print.Schäfer, Florian. 2009. "The Causative Alternation". Language and Linguistics Compass 3.2: 641. Print. A causatively alternating verb, called a labile or ergative verb, such as "open", has both a transitive meaning ("I opened the door") and an intransitive meaning ("The door opened"). When causatively alternating verbs are used transitively they are called causatives since, in the transitive use of the verb, the subject is ''causing'' the action denoted by the intransitive version. When causatively alternating verbs are used intransitively, they are referred to as anticausatives or inchoatives because the intransitive variant describes a situation in which the ''the ...
