Marked
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 ... [...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] |
Inflection
In linguistic morphology, inflection (or inflexion) is a process of word formation in which a word is modified to express different grammatical categories such as tense, case, voice, aspect, person, number, gender, mood, animacy, and definiteness. The inflection of verbs is called ''conjugation'', and one can refer to the inflection of nouns, adjectives, adverbs, pronouns, determiners, participles, prepositions and postpositions, numerals, articles, etc., as ''declension''. An inflection expresses grammatical categories with affixation (such as prefix, suffix, infix, circumfix, and transfix), apophony (as Indo-European ablaut), or other modifications. For example, the Latin verb ', meaning "I will lead", includes the suffix ', expressing person (first), number (singular), and tense-mood (future indicative or present subjunctive). The use of this suffix is an inflection. In contrast, in the English clause "I will lead", the word ''lead'' is not inflected for any of pe ...

Language Loss
Language attrition is the process of losing a native or first language. This process is generally caused by both isolation from speakers of the first language ("L1") and the acquisition and use of a second language ("L2"), which interferes with the correct production and comprehension of the first. Such interference from a second language is probably experienced to some extent by all bilinguals, but is most evident among speakers for whom a language other than their first has started to play an important, if not dominant, role in everyday life; these speakers are more likely to experience language attrition. It is common among immigrants that travel to countries where languages foreign to them are used. There are several factors which affect the process. Frequent exposure and use of a particular language is often assumed adequate to maintain the native language system intact. However, research has often failed to confirm this prediction. A positive attitude towards the potential ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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) Binary classification, classifications, introduced by biochemist Brian Matthews (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 varia ...

West Frisian Language
West Frisian, or simply Frisian ( fy, link=no, Frysk or ; nl, Fries , also ), is a West Germanic language spoken mostly in the province of Friesland () in the north of the Netherlands, mostly by those of Frisian ancestry. It is the most widely spoken of the Frisian languages. In the study of the evolution of English, West Frisian is notable as being the most closely related foreign tongue to the various dialects of Old English spoken across the Heptarchy, these being part of the Anglo-Frisian branch of the West Germanic family. Name The name "West Frisian" is only used outside the Netherlands, to distinguish this language from the closely related Frisian languages of Saterland Frisian and North Frisian spoken in Germany. Within the Netherlands, however, "West Frisian" refers to the West Frisian dialect of the Dutch language while the West Frisian language is almost always just called "Frisian" (in Dutch: for the Frisian language and for the Dutch dialect).

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 ...

Aphasia
Aphasia is an inability to comprehend or formulate language because of damage to specific brain regions. The major causes are stroke and head trauma; prevalence is hard to determine but aphasia due to stroke is estimated to be 0.1–0.4% in the Global North. Aphasia can also be the result of brain tumors, brain infections, or neurodegenerative diseases (such as dementias). To be diagnosed with aphasia, a person's speech or language must be significantly impaired in one (or more) of the four aspects of communication following acquired brain injury. Alternatively, in the case of progressive aphasia, it must have significantly declined over a short period of time. The four aspects of communication are auditory comprehension, verbal expression, reading and writing, and functional communication. The difficulties of people with aphasia can range from occasional trouble finding words, to losing the ability to speak, read, or write; intelligence, however, is unaffected. Expressive lan ...

Semantic Analysis (linguistics)
In linguistics, semantic analysis is the process of relating syntactic structures, from the levels of phrases, clauses, sentences and paragraphs to the level of the writing as a whole, to their language-independent meanings. It also involves removing features specific to particular linguistic and cultural contexts, to the extent that such a project is possible. The elements of idiom and figurative speech, being cultural, are often also converted into relatively invariant meanings in semantic analysis. Semantics, although related to pragmatics, is distinct in that the former deals with word or sentence choice in any given context, while pragmatics considers the unique or particular meaning derived from context or tone. To reiterate in different terms, semantics is about universally coded meaning, and pragmatics, the meaning encoded in words that is then interpreted by an audience. Semantic analysis can begin with the relationship between individual words. This requires an under ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thomas Givon
Thomas Givon (also known as Talmy Givón) (born June 22, 1936) is a linguist and writer. He is one of the founders of "West Coast Functionalism", today classified as a usage-based model of language, and of the linguistics department at the University of Oregon. Givón advocates an evolutionary approach to language and communication. Education Givón earned his bachelor of science degree cum laude in agriculture from the Hebrew University of Jerusalem in 1959. Attending UCLA, he received a Master of Science degree in horticulture in 1962, a C.Phil in Plant Biochemistry, a Master of Arts degree in linguistics in 1966, and a PhD in linguistics in 1969, as well as an TESL certificate in 1965. 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 Cali ... [...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 negative ...

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 ...
