Numeric Annotation Glyphs
Numeric Annotation Glyphs or NAGs are used to annotate chess games when using a computer, typically providing an assessment of a chess move or a chess position. NAGs exist to indicate a simple annotation in a language independent manner. NAGs were first formally documented in 1994 by Steven J. Edwards in his Portable Game Notation Specification and Implementation Guide. Within the PGN specification, 256 NAGs are proposed of which the first 140 are defined; the remainder were reserved for future definition. Introduction A Numeric Annotation Glyph is composed of a dollar sign character ("$") immediately followed by one or more digit characters. Each NAG then has a specific meaning and often a standard typographical representation. The meanings first defined stemmed from the use of specific typographic symbols when annotators were commenting upon chess games; most especially in Chess Informant ''Uses FigurineCB webfont.'' publications. The objective was to devise an alternative repre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Portable Game Notation
Portable Game Notation (PGN) is a standard plain text format for recording chess games (both the moves and related data), which can be read by humans and is also supported by most chess software. History PGN was devised around 1993, by Steven J. Edwards, and was first popularized and specified via the Usenet newsgroup rec.games.chess. Usage PGN is structured "for easy reading and writing by human users and for easy parsing and generation by computer programs." The chess moves themselves are given in algebraic chess notation using English initials for the pieces. The filename extension is .pgn. There are two formats in the PGN specification, the "import" format and the "export" format. The import format describes data that may have been prepared by hand, and is intentionally lax; a program that can read PGN data should be able to handle the somewhat lax import format. The export format is rather strict and describes data prepared under program control, similar to a pretty printe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chess Informant
Chess Informant (Šahovski Informator) is a publishing company from Belgrade (Serbia, former Yugoslavia) that periodically (since 2012, four volumes per year) produces a book entitled ''Chess Informant'', as well as the ''Encyclopaedia of Chess Openings'', ''Encyclopaedia of Chess Endings'', ''Opening Monographs'', other print publications, and software (including electronic editions of most print publications). Aleksandar Matanović and Milivoje Molerović founded the company in 1966 for the purpose of offering the rest of the world the sort of access to chess information enjoyed by Soviet players. The company has sold three million books in 150 countries, according to its website.Chess Informant website , "About Us" section Chess Informant published two issues per year in 1966–1990, three issues per year in 1991 ...

Non-standard NAGs
Standardization or standardisation is the process of implementing and developing technical standards based on the consensus of different parties that include firms, users, interest groups, standards organizations and governments. Standardization can help maximize compatibility, interoperability, safety, repeatability, or quality. It can also facilitate a normalization of formerly custom processes. In social sciences, including economics, the idea of ''standardization'' is close to the solution for a coordination problem, a situation in which all parties can realize mutual gains, but only by making mutually consistent decisions. History Early examples Standard weights and measures were developed by the Indus Valley civilization.Iwata, Shigeo (2008), "Weights and Measures in the Indus Valley", ''Encyclopaedia of the History of Science, Technology, and Medicine in Non-Western Cultures (2nd edition)'' edited by Helaine Selin, pp. 2254–2255, Springer, .

Chess Annotation Symbols
When annotating chess games, commentators frequently use widely recognized annotation symbols. Question marks and exclamation points that denote a move as bad or good are ubiquitous in chess literature. Some publications intended for an international audience, such as the ''Chess Informant'', have a wide range of additional symbols that transcend language barriers. The common symbols for evaluating the merits of a move are "??", "?", "?!", "!?", "!", and "!!". The chosen symbol is appended to the text describing the move (e.g. Re7? or Kh1!?); see Algebraic chess notation. Use of these annotation symbols is subjective, as different annotators use the same symbols differently. Moreover, an annotator's use of symbols is often influenced by the player's strength: for example, a positional misjudgment that an annotator might give a "??" if played by a strong grandmaster might pass unremarked if played by a novice. Annotators' use of punctuation may also be influenced by the result o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hyphen-minus
The hyphen-minus is the most commonly used type of hyphen, widely used in digital documents. It is the only character that looks like a minus sign or a dash in many character sets such as ASCII or on most keyboards, so it is also used as such. The name "hyphen-minus" derives from the original ASCII standard, where it was called "hyphen(minus)". The character is referred to as a "hyphen", a "minus sign", or a "dash" according to the context where it is being used. Description In early monospaced font typewriters and character encodings, a single key/code was almost always used for hyphen, minus, various dashes, and strikethrough, since they all have a roughly similar appearance. The current Unicode Standard specifies distinct characters for a number of different dashes, an unambiguous minus sign ("Unicode minus") at code point U+2212, and various types of hyphen including the unambiguous "Unicode hyphen" at U+2010 and the hyphen-minus at U+002D. When a hyphen is called for, the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mathematical Operators And Symbols In Unicode
The Unicode Standard encodes almost all standard characters used in mathematics. Unicode Technical Report #25 provides comprehensive information about the character repertoire, their properties, and guidelines for implementation. Mathematical operators and symbols are in multiple Unicode blocks. Some of these blocks are dedicated to, or primarily contain, mathematical characters while others are a mix of mathematical and non-mathematical characters. This article covers all Unicode characters with a derived property of "Math". Dedicated blocks Mathematical Operators block The Mathematical Operators block (U+2200–U+22FF) contains characters for mathematical, logical, and set notation. Supplemental Mathematical Operators block The Supplemental Mathematical Operators block (U+2A00–U+2AFF) contains various mathematical symbols, including N-ary operators, summations and integrals, intersections and unions, logical and relational operators, and subset/superset relatio ...
