Classification Systems By Subject
Classification is a process related to categorization, the process in which ideas and objects are recognized, differentiated and understood. Classification is the grouping of related facts into classes. It may also refer to: Business, organizations, and economics * Classification of customers, for marketing (as in Master data management) or for profitability (e.g. by Activity-based costing) * Classified information, as in legal or government documentation * Job classification, as in job analysis * Standard Industrial Classification, economic activities Mathematics * Attribute-value system, a basic knowledge representation framework * Classification theorems in mathematics * Class (set theory), Mathematical classification, grouping mathematical objects based on a property that all those objects share * Statistical classification, identifying to which of a set of categories a new observation belongs, on the basis of a training set of data Media * Classification (literature), a f ...

Categorization
Categorization is the ability and activity of recognizing shared features or similarities between the elements of the experience of the world (such as Object (philosophy), objects, events, or ideas), organizing and classifying experience by associating them to a more abstract group (that is, a category, class, or type), on the basis of their traits, features, similarities or other criteria that are Universal (metaphysics), universal to the group. Categorization is considered one of the most fundamental cognitive abilities, and as such it is studied particularly by psychology and cognitive linguistics. Categorization is sometimes considered synonymous with classification (cf., Classification (general theory)#Synonyms and near-synonyms, Classification synonyms). Categorization and classification allow humans to organize things, objects, and ideas that exist around them and simplify their understanding of the world. Categorization is something that humans and other organisms ''do ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Biological Classification
In biology, taxonomy () is the scientific study of naming, defining ( circumscribing) and classifying groups of biological organisms based on shared characteristics. Organisms are grouped into taxa (singular: taxon) and these groups are given a taxonomic rank; groups of a given rank can be aggregated to form a more inclusive group of higher rank, thus creating a taxonomic hierarchy. The principal ranks in modern use are domain, kingdom, phylum (''division'' is sometimes used in botany in place of ''phylum''), class, order, family, genus, and species. The Swedish botanist Carl Linnaeus is regarded as the founder of the current system of taxonomy, as he developed a ranked system known as Linnaean taxonomy for categorizing organisms and binomial nomenclature for naming organisms. With advances in the theory, data and analytical technology of biological systematics, the Linnaean system has transformed into a system of modern biological classification intended to reflect the evolut ...

Product Classification
Product classification or product taxonomy is a type of economic taxonomy which organizes products for a variety of purposes. However, not only products can be referred to in a standardized way but also sales practices in form of the “Incoterms” and industries can be classified into categories. Some standard product classifications include: * CPA — Classification of Products by Activity, a product nomenclature that was used in the European Economic Community and now in use in the EU, a European version of the CPC ** CPA 1996 ** CPA 2002 ** CPA 2008 ** CPA 2.1 * CPC — Central Product Classification, a United Nations standard classification for products * ETIM, the ETIM Technical Information Model * Global Classification and Harmonized Schedule Numbers for customs classification * HS — Harmonized Commodity Description and Coding System * SITC — Standard International Trade Classification * Trade in Services * UNSPSC, the United Nations Standard Products and Services C ...

Locomotive Classification
A class of locomotives is a group of locomotives built to a common design, typically for a single railroad or railway. Often members of a particular class had detail variations between individual examples, and these could lead to subclasses. Sometimes technical alterations (especially rebuilding, superheating, re-engining, etc.) move a locomotive from one class to another. Different railways had different systems, and sometimes one railway (or its successors) used different systems at different times and for different purposes, or applied those classifications inconsistently. Sometimes therefore it is not clear where one class begins and another ends. The result is a classic example of the Lumper splitter problem. US-American practice Development As locomotives became more numerous the need arose to deal with them in groups of similar engines rather than as named or numbered individuals. These groups were named "classes" and at first tended to reflect capability rather than desi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Classification Society
A ship classification society or ship classification organisation is a non-governmental organization that establishes and maintains technical standards for the construction and operation of ships and offshore structures. Classification societies certify that the construction of a vessel comply with relevant standards and carry out regular surveys in service to ensure continuing compliance with the standards. Currently, more than 50 organizations describe their activities as including marine classification, twelve of which are members of the International Association of Classification Societies. A classification certificate issued by a classification society recognised by the proposed ship register is required for a ship's owner to be able to register the ship and to obtain marine insurance on the ship, and may be required to be produced before a ship's entry into some ports or waterways, and may be of interest to charterers and potential buyers. To avoid liability, classification ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Classification Of Wine
The classification of wine is based on various criteria including place of origin or appellation, vinification method and style, sweetness and vintage,J. Robinson (ed) ''"The Oxford Companion to Wine"'' Third Edition pg 752 & 753 Oxford University Press 2006 . and the grape variety or varieties used. Practices vary in different countries and regions of origin, and many practices have varied over time. Some classifications enjoy official protection by being part of the wine law in their country of origin, while others have been created by, for example, growers' organizations without such protection. The term "wine" Within the European Union, the term "wine" and its equivalents in other languages is reserved exclusively for the fermented juice of grapes.Harding, G. ''A Wine Miscellany'', pp. 5-9. Clarkson Potter Publishing (New York), 2005. . In the United States, the term is also used for the fermented juice of any fruit [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Classification Of Swords
The English language terminology used in the classification of swords is imprecise and has varied widely over time. There is no historical dictionary for the universal names, classification or terminology of swords; a sword was simply a double edged knife. Historical terms without a universal consensus of definition (i.e. "arming sword", "broadsword", "long sword", etc.) were used to label weapons of similar appearance but of different historical periods, regional cultures and fabrication technology. These terms were often described in relation to other unrelated weapons, without regard to their intended use and fighting style. In modern history, many of these terms have been given specific, often arbitrary meanings that are unrelated to any of their historical meanings. Terminology Some of these terms originate contemporaneously with the weapons which they describe. Others are modern or early modern terms used by antiquarians, curators, and modern-day sword enthusiasts for hi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Civil Service
The civil service is a collective term for a sector of government composed mainly of career civil servants hired on professional merit rather than appointed or elected, whose institutional tenure typically survives transitions of political leadership. A civil servant, also known as a public servant, is a person employed in the public sector by a government department or agency for public sector undertakings. Civil servants work for central and state governments, and answer to the government, not a political party. The extent of civil servants of a state as part of the "civil service" varies from country to country. In the United Kingdom (UK), for instance, only Crown (national government) employees are referred to as "civil servants" whereas employees of local authorities (counties, cities and similar administrations) are generally referred to as "local government civil service officers", who are considered public servants but not civil servants. Thus, in the UK, a civil servant is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mechanical Screening
Mechanical screening, often just called screening, is the practice of taking Granule (geology), granulated or crushed ore material and separating it into multiple Ore grade, grades by particle size. This practice occurs in a variety of industries such as mining and mineral processing, agriculture, pharmaceutical, food, plastics, and recycling. A method of separating solid particles according to size alone is called screening. General categories Screening falls under two general categories: dry screening, and wet screening. From these categories, screening separates a flow of material into grades, these grades are then either further processed to an intermediary product or a finished product. Additionally, the machines can be categorized into a moving screen and static screen machines, as well as by whether the screens are horizontal or inclined. Applications The mining and mineral processing industry uses screening for a variety of processing applications. For example, after mi ...

Process (engineering)
In engineering, a process is a series of interrelated tasks that, together, transform inputs into a given output. These tasks may be carried out by people, nature or machines using various resources; an engineering process must be considered in the context of the agents carrying out the tasks and the resource attributes involved.Gilb, p392 Systems engineering normative documents and those related to Maturity Models are typically based on processes, for example, systems engineering processes of the EIA-632 and processes involved in the Capability Maturity Model Integration (CMMI) institutionalization and improvement approach. Constraints imposed on the tasks and resources required to implement them are essential for executing the tasks mentioned. Semiconductor industry Semiconductor process engineers face the unique challenge of transforming raw materials into high-tech devices. Common semiconductor devices include Integrated Circuits (ICs), Light-Emitting Diodes (LEDs), solar c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
International Society For Knowledge Organization
The International Society for Knowledge Organization, or ISKO, is a professional association for scholars of knowledge organization, knowledge structures, classification studies, and information organization and structure. Publications The Society publishes the academic journal ''Knowledge Organization'' as the official bi-monthly journal of ISKO. Founded in 1973 by Dr. Ingetraut Dahlberg, the first President of ISKO, it began publication the following year under the banner International Classification. In 1993 the title was changed to its present form. The journal publishes original research articles relating to general ordering theory, philosophical foundations of knowledge and its artifacts, theoretical bases of classification, data analysis and reduction. It also describes practical operations associated with indexing and classification. In addition to being a technical resource, the journal traces the history of knowledge organization and discusses questions of education a ...

Cladistics
Cladistics (; ) is an approach to biological classification in which organisms are categorized in groups (" clades") based on hypotheses of most recent common ancestry. The evidence for hypothesized relationships is typically shared derived characteristics ( synapomorphies'')'' that are not present in more distant groups and ancestors. However, from an empirical perspective, common ancestors are inferences based on a cladistic hypothesis of relationships of taxa whose character states can be observed. Theoretically, a last common ancestor and all its descendants constitute a (minimal) clade. Importantly, all descendants stay in their overarching ancestral clade. For example, if the terms ''worms'' or ''fishes'' were used within a ''strict'' cladistic framework, these terms would include humans. Many of these terms are normally used paraphyletically, outside of cladistics, e.g. as a 'grade', which are fruitless to precisely delineate, especially when including extinct species. R ...
