XML Schema
An XML schema is a description of a type of XML document, typically expressed in terms of constraints on the structure and content of documents of that type, above and beyond the basic syntactical constraints imposed by XML itself. These constraints are generally expressed using some combination of grammatical rules governing the order of elements, Boolean predicates that the content must satisfy, data types governing the content of elements and attributes, and more specialized rules such as uniqueness and referential integrity constraints. There are languages developed specifically to express XML schemas. The document type definition (DTD) language, which is native to the XML specification, is a schema language that is of relatively limited capability, but that also has other uses in XML aside from the expression of schemas. Two more expressive XML schema languages in widespread use are XML Schema (with a capital ''S'') and RELAX NG. The mechanism for associating an XML d ...

Schema (Kant)
In Kantian philosophy, a transcendental schema (plural: ''schemata''; from grc-gre, σχῆμα, "form, shape, figure") is the procedural rule by which a category or pure, non- empirical concept is associated with a sense impression. A private, subjective intuition is thereby discursively thought to be a representation of an external object. Transcendental schemata are supposedly produced by the imagination in relation to time. Role in Kant's architectonic system Kant created an architectonic system in which there is a progression of phases from the most formal to the most empirical: "Kant develops his system of corporeal nature in the following way. He starts in the ''Critique'' with the most formal act of human cognition, called by him the transcendental unity of apperception, and its various aspects, called the logical functions of judgment. He then proceeds to the pure categories of the understanding, and then to the schematized categories, and finally to the transcenden ...

Schema (psychology)
In psychology and cognitive science, a schema (plural ''schemata'' or ''schemas'') describes a pattern of thought or behavior that organizes categories of information and the relationships among them. It can also be described as a mental structure of preconceived ideas, a framework representing some aspect of the world, or a system of organizing and perceiving new information, such as a mental schema or conceptual model. Schemata influence attention and the absorption of new knowledge: people are more likely to notice things that fit into their schema, while re-interpreting contradictions to the schema as exceptions or distorting them to fit. Schemata have a tendency to remain unchanged, even in the face of contradictory information. Schemata can help in understanding the world and the rapidly changing environment. People can organize new perceptions into schemata quickly as most situations do not require complex thought when using schema, since automatic thought is all that is ...

Great Schema
The degrees of Eastern Orthodox and Eastern Catholic monasticism are the stages an Eastern Orthodox monk or nun passes through in their religious vocation. In the Eastern Orthodox Church, the process of becoming a monk or nun is intentionally slow, as the monastic vows taken are considered to entail a lifelong commitment to God, and are not to be entered into lightly. After a person completes the novitiate, three degrees or steps must be completed in the process of preparation before one may gain the monastic habit. Orthodox monasticism Unlike in Western Christianity, where different religious orders and societies arose, each with its own profession rites, the Eastern Orthodox Church has only one type of monasticism. The profession of monastics is known as tonsure (referring to the ritual cutting of the monastic's hair which takes place during the service) and was, at one time, considered to be a Sacred Mystery (sacrament). The Rite of Tonsure is printed in the ''Euchologion'' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Image Schema
An image schema (both ''schemas'' and ''schemata'' are used as plural forms) is a recurring structure within our cognitive processes which establishes patterns of understanding and reasoning. As an understudy to embodied cognition, image schemas are formed from our bodily interactions, from linguistic experience, and from historical context. The term is introduced in Mark Johnson's book ''The Body in the Mind''; in case study 2 of George Lakoff's ''Women, Fire and Dangerous Things:'' and further explained by Todd Oakley in ''The Oxford handbook of cognitive linguistics;'' by Rudolf Arnheim in ''Visual Thinking''; by the collection ''From Perception to Meaning: Image Schemas in Cognitive Linguistics'' edited by Beate Hampe and Joseph E. Grady. In contemporary cognitive linguistics, an image schema is considered an embodied prelinguistic structure of experience that motivates conceptual metaphor mappings. Learned in early infancy they are often described as spatiotemporal relat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Schematic
A schematic, or schematic diagram, is a designed representation of the elements of a system using abstract, graphic symbols rather than realistic pictures. A schematic usually omits all details that are not relevant to the key information the schematic is intended to convey, and may include oversimplified elements in order to make this essential meaning easier to grasp, as well as additional organization of the information. For example, a subway map intended for passengers may represent a subway station with a dot. The dot is not intended to resemble the actual station at all but aims to give the viewer information without unnecessary visual clutter. A schematic diagram of a chemical process uses symbols in place of detailed representations of the vessels, piping, valves, pumps, and other equipment that compose the system, thus emphasizing the functions of the individual elements and the interconnections among them and suppresses their physical details.

Database Schema
The database schema is the structure of a database described in a formal language supported by the database management system (DBMS). The term "schema" refers to the organization of data as a blueprint of how the database is constructed (divided into database tables in the case of relational databases). The formal definition of a database schema is a set of formulas (sentences) called integrity constraints imposed on a database. These integrity constraints ensure compatibility between parts of the schema. All constraints are expressible in the same language. A database can be considered a structure in realization of the database language. The states of a created conceptual schema are transformed into an explicit mapping, the database schema. This describes how real-world entities are modeled in the database. "A database schema specifies, based on the database administrator's knowledge of possible applications, the facts that can enter the database, or those of interest to ...

Schema (genetic Algorithms)
A schema () is a template in computer science used in the field of genetic algorithms that identifies a subset of strings with similarities at certain string positions. Schemata are a special case of cylinder sets, forming a basis for a product topology on strings. In other words, schemata can be used to generate a topology on a space of strings. Description For example, consider binary strings of length 6. The schema 1**0*1 describes the set of all words of length 6 with 1's at the first and sixth positions and a 0 at the fourth position. The * is a wildcard symbol, which means that positions 2, 3 and 5 can have a value of either 1 or 0. The ''order of a schema'' is defined as the number of fixed positions in the template, while the ''defining length'' \delta(H) is the distance between the first and last specific positions. The order of 1**0*1 is 3 and its defining length is 5. The ''fitness of a schema'' is the average fitness of all strings matching the schema. The fitness ...

Axiom Schema
In mathematical logic, an axiom schema (plural: axiom schemata or axiom schemas) generalizes the notion of axiom. Formal definition An axiom schema is a formula in the metalanguage of an axiomatic system, in which one or more schematic variables appear. These variables, which are metalinguistic constructs, stand for any term or subformula of the system, which may or may not be required to satisfy certain conditions. Often, such conditions require that certain variables be free, or that certain variables not appear in the subformula or term. Finite axiomatization Given that the number of possible subformulas or terms that can be inserted in place of a schematic variable is countably infinite, an axiom schema stands for a countably infinite set of axioms. This set can usually be defined recursively. A theory that can be axiomatized without schemata is said to be finitely axiomatized. Theories that can be finitely axiomatized are seen as a bit more metamathematically elegant, even ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
