Markedness
In linguistics and social sciences, markedness is the state of standing out as nontypical or divergent as opposed to regular or common. In a marked–unmarked relation, one term of an opposition is the broader, dominant one. The dominant default or minimum-effort form is known as ''unmarked''; the other, secondary one is ''marked''. In other words, markedness involves the characterization of a "normal" linguistic unit against one or more of its possible "irregular" forms. In linguistics, markedness can apply to, among others, phonological, grammatical, and semantic oppositions, defining them in terms of marked and unmarked oppositions, such as ''honest'' (unmarked) vs. ''dishonest'' (marked). Marking may be purely semantic, or may be realized as extra morphology. The term derives from the marking of a grammatical role with a suffix or another element, and has been extended to situations where there is no morphological distinction. In social sciences more broadly, markedness i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Edwin Battistella
Edwin Battistella (born 1955) is an American linguist known for work on markedness, syntax, and language attitudes. He is an emeritus professor of Humanities and Culture at Southern Oregon University in Ashland, Oregon. Background Battistella studied Slavic languages and literatures at Rutgers College, completing a BA in 1976, and linguistics at the City University of New York Graduate School and University Center, receiving a Ph.D. in 1981. His dissertation, ''Topics in the Theory of Inflection'', written under the direction of Robert Fiengo, developed the early theory of abstract case introduced in Noam Chomsky’s 1980 article "On Case Theory". The dissertation proposed that many instances of grammatical agreement could be treated as the assignment of abstract case features from clauses to the categories they contained, making a distinction between inherent and assigned case features. Scholarly contributions Battistella is the author of two books on the theory of markedness. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Informedness
Youden's J statistic (also called Youden's index) is a single statistic that captures the performance of a dichotomous diagnostic test. Informedness is its generalization to the multiclass case and estimates the probability of an informed decision. Definition Youden's ''J'' statistic is : J = \text + \text -1 with the two right-hand quantities being sensitivity and specificity. Thus the expanded formula is: : J = \frac+\frac-1 The index was suggested by W.J. Youden in 1950 as a way of summarising the performance of a diagnostic test, however the formula was earlier published in Science by C.S.Pierce in 1884. Its value ranges from -1 through 1 (inclusive), and has a zero value when a diagnostic test gives the same proportion of positive results for groups with and without the disease, i.e the test is useless. A value of 1 indicates that there are no false positives or false negatives, i.e. the test is perfect. The index gives equal weight to false positive and false negativ ...

Confusion Matrix
In the field of machine learning and specifically the problem of statistical classification, a confusion matrix, also known as an error matrix, is a specific table layout that allows visualization of the performance of an algorithm, typically a supervised learning one (in unsupervised learning it is usually called a matching matrix). Each row of the matrix represents the instances in an actual class while each column represents the instances in a predicted class, or vice versa – both variants are found in the literature. The name stems from the fact that it makes it easy to see whether the system is confusing two classes (i.e. commonly mislabeling one as another). It is a special kind of contingency table, with two dimensions ("actual" and "predicted"), and identical sets of "classes" in both dimensions (each combination of dimension and class is a variable in the contingency table). __TOC__ Example Given a sample of 12 individuals, 8 that have been diagnosed with cancer an ...

Matthews Correlation Coefficient
In statistics, the phi coefficient (or mean square contingency coefficient and denoted by φ or rφ) is a measure of association for two binary variables. In machine learning, it is known as the Matthews correlation coefficient (MCC) and used as a measure of the quality of binary (two-class) classifications, introduced by biochemist Brian W. Matthews in 1975. Introduced by Karl Pearson, and also known as the ''Yule phi coefficient'' from its introduction by Udny Yule in 1912 this measure is similar to the Pearson correlation coefficient in its interpretation. In fact, a Pearson correlation coefficient estimated for two binary variables will return the phi coefficient. Two binary variables are considered positively associated if most of the data falls along the diagonal cells. In contrast, two binary variables are considered negatively associated if most of the data falls off the diagonal. If we have a 2×2 table for two random variables ''x'' and ''y'' where ''n''11, ''n'' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prague School (linguistics)
The Prague school or Prague linguistic circle is a language and literature society. It started in 1926 as a group of linguists, philologists and literary critics in Prague. Its proponents developed methods of structuralist literary analysis and a theory of the standard language and of language cultivation from 1928 to 1939. The linguistic circle was founded in the Café Derby in Prague, which is also where meetings took place during its first years. The Prague School has had a significant continuing influence on linguistics and semiotics. After the Czechoslovak coup d'état of 1948, the circle was disbanded in 1952, but the Prague School continued as a major force in linguistic functionalism (distinct from the Copenhagen school or English Firthian – later Hallidean – linguistics). The American scholar Dell Hymes cites his 1962 paper, "The Ethnography of Speaking," as the formal introduction of Prague functionalism to American linguistic anthropology. The Prague ...

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 (ho ...

Career In 1966 Givón worked for System Development Corporation as a research associate in lexicography. The following year he went to University of Zambia where he researched Bantu languages. In 1969 he became an assistant professor of Linguistics and African Languages at University of Ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Context (language Use)
In semiotics, linguistics, sociology and anthropology, context refers to those objects or entities which surround a ''focal event'', in these disciplines typically a communicative event, of some kind. Context is "a frame that surrounds the event and provides resources for its appropriate interpretation". It is thus a relative concept, only definable with respect to some focal event within a frame, not independently of that frame. In linguistics In the 19th century, it was debated whether the most fundamental principle in language was contextuality or compositionality, and compositionality was usually preferred.Janssen, T. M. (2012) Compositionality: Its historic context', in M. Werning, W. Hinzen, & E. Machery (Eds.), The Oxford handbook of compositionality', pp. 19-46, Oxford University Press. Verbal context refers to the text or speech surrounding an expression (word, sentence, or speech act). Verbal context influences the way an expression is understood; hence the norm of n ...

Rodney Needham
Rodney Needham (15 May 1923 – 4 December 2006 in Oxford) was an English social anthropologist. Born Rodney Phillip Needham Green, he changed his name in 1947; the following year he married Maud Claudia (Ruth) Brysz. The couple would collaborate on several works, including an English translation of Robert Hertz's ''Death and the Right Hand.'' His fieldwork was with the Penan of Borneo (1951-2) and the Siwang of Malaysia (1953-5). His doctoral thesis on the Penan was accepted in 1953. He was University Lecturer in Social Anthropology, Oxford University, 1956–76; Professor of Social Anthropology, Oxford, 1976–90; Official Fellow, Merton College, Oxford, 1971–75; and Fellow, All Souls College, Oxford, 1976-90. Together with Edmund Leach and Mary Douglas, Needham brought structuralism from France and anglicised it in the process. A prolific scholar, he was also a teacher and a rediscoverer of neglected figures in the history of his discipline, such as Arnold Van Gen ...
