Disambiguation
Word-sense disambiguation (WSD) is the process of identifying which sense of a word is meant in a sentence or other segment of context. In human language processing and cognition, it is usually subconscious/automatic but can often come to conscious attention when ambiguity impairs clarity of communication, given the pervasive polysemy in natural language. In computational linguistics, it is an open problem that affects other computer-related writing, such as discourse, improving relevance of search engines, anaphora resolution, coherence, and inference. Given that natural language requires reflection of neurological reality, as shaped by the abilities provided by the brain's neural networks, computer science has had a long-term challenge in developing the ability in computers to do natural language processing and machine learning. Many techniques have been researched, including dictionary-based methods that use the knowledge encoded in lexical resources, supervised machine lea ...

Manual Of Style (disambiguation Pages)
A style guide or manual of style is a set of standards for the writing, formatting, and design of documents. It is often called a style sheet, although that term also has multiple other meanings. The standards can be applied either for general use, or be required usage for an individual publication, a particular organization, or a specific field. A style guide establishes standard style requirements to improve communication by ensuring consistency both within a document, and across multiple documents. Because practices vary, a style guide may set out standards to be used in areas such as punctuation, capitalization, citing sources, formatting of numbers and dates, table appearance and other areas. The style guide may require certain best practices in writing style, usage, language composition, visual composition, orthography, and typography. For academic and technical documents, a guide may also enforce the best practice in ethics (such as authorship, research ethics, and ...

Medical Reversal
Medical reversal refers to when a newer and methodologically superior clinical trial produces results that contradict existing clinical practice and the older trials on which it is based. This leads to an intervention that was widely used falling out of favor, because new evidence either demonstrates that it is ineffective or that its harms exceed its benefits. It is distinct from replacement, which occurs when a newly developed medical treatment supersedes an older, less effective one as the standard of care. Medical reversals are caused when a treatment is widely adopted even when there is not compelling evidence for its safety and effectiveness. For example, an intervention may be adopted because it "makes sense", or because there are observational studies supporting its putative benefits. The negative effects of such reversals include harm to patients who received the intervention when it was considered relatively safe and effective, as well as reducing public trust in medicine. ...

Reversal (law)
In law, an appeal is the process in which cases are reviewed by a higher authority, where parties request a formal change to an official decision. Appeals function both as a process for error correction as well as a process of clarifying and interpreting law. Although appellate courts have existed for thousands of years, common law countries did not incorporate an affirmative right to appeal into their jurisprudence until the 19th century. History Appellate courts and other systems of error correction have existed for many millennia. During the first dynasty of Babylon, Hammurabi and his governors served as the highest appellate courts of the land. Ancient Roman law recognized the right to appeal in the Valerian and Porcian laws since 509 BC. Later it employed a complex hierarchy of appellate courts, where some appeals would be heard by the emperor. Additionally, appellate courts have existed in Japan since at least the Kamakura Shogunate (1185–1333 CE). During this time, ...

Peripeteia
Peripeteia ( el, περιπέτεια) is a reversal of circumstances, or turning point. The term is primarily used with reference to works of literature; its anglicized form is peripety. Aristotle's view Aristotle, in his ''Poetics'', defines peripeteia as "a change by which the action veers round to its opposite, subject always to our rule of probability or necessity." According to Aristotle, peripeteia, along with discovery, is the most effective when it comes to drama, particularly in a tragedy. He wrote that "The finest form of Discovery is one attended by Peripeteia, like that which goes with the Discovery in Oedipus...". Aristotle says that peripeteia is the most powerful part of a plot in a tragedy along with discovery. A peripety is the change of the kind described from one state of things within the play to its opposite, and that too in the way we are saying, in the probable or necessary sequence of events. There is often no element like Peripeteia; it can bring forth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reversal Film
In photography, reversal film or slide film is a type of photographic film that produces a positive image on a transparent base. Instead of negatives and prints, reversal film is processed to produce transparencies or diapositives (abbreviated as "diafilm" or "dia" in some languages like German or Hungarian). Reversal film is produced in various sizes, from 35 mm to roll film to 8×10 inch sheet film. A slide is a specially mounted individual transparency intended for projection onto a screen using a slide projector. This allows the photograph to be viewed by a large audience at once. The most common form is the 35 mm slide, with the image framed in a 2×2 inch cardboard or plastic mount. Some specialized labs produce photographic slides from digital camera images in formats such as JPEG, from computer-generated presentation graphics, and from a wide variety of physical source material such as fingerprints, microscopic sections, paper documents, astronomical imag ...

Reversal (wrestling)
Collegiate wrestling (also known as folkstyle wrestling) is the form of wrestling practiced at the college and university level in the United States. This style of wrestling, with some slight modifications, is also practiced at high school and middle school levels, and also among younger participants. The rules and style of collegiate or folkstyle wrestling differs from other styles of wrestling that are practiced around the world such as those in the Olympic Games, freestyle wrestling and Greco-Roman wrestling. Women's wrestling at the US college level uses two different rulesets. The National Wrestling Coaches Association, whose women's division is now recognized by the NCAA as part of its Emerging Sports for Women program, uses the freestyle ruleset as defined by the sport's international governing body, United World Wrestling. The National Collegiate Wrestling Association, a separate governing body that conducts competition for colleges and universities parallel to but outsid ...

Options Arbitrage
Options arbitrage is a trading strategy using arbitrage in the options market to earn small profits with very little or zero risk. Traders perform conversions when options are relatively overpriced by purchasing stock and selling the equivalent options position. When the options are relatively underpriced, traders will do reverse conversions or reversals. In practice, actionable option arbitrage opportunities have decreased with the advent of automated trading strategies. Conversion A ''conversion'' position is: * short a call, * long a put, and * long the underlying The call and put have the same strike value and expiration date. The resulting portfolio is delta neutral. One reason a trader may take this position would be to extend the holding period of the underlying position for capital gains tax purposes, while locking in the current price. Reversal A ''reversal'' (or reverse conversion) position is: * long a call, * short a put, and * short the underlying. The ...

Formal Language
In logic, mathematics, computer science, and linguistics, a formal language consists of words whose letters are taken from an alphabet and are well-formed according to a specific set of rules. The alphabet of a formal language consists of symbols, letters, or tokens that concatenate into strings of the language. Each string concatenated from symbols of this alphabet is called a word, and the words that belong to a particular formal language are sometimes called ''well-formed words'' or ''well-formed formulas''. A formal language is often defined by means of a formal grammar such as a regular grammar or context-free grammar, which consists of its formation rules. In computer science, formal languages are used among others as the basis for defining the grammar of programming languages and formalized versions of subsets of natural languages in which the words of the language represent concepts that are associated with particular meanings or semantics.
