Faceted Classification
A faceted classification is a classification scheme used in organizing knowledge into a systematic order. A faceted classification uses semantic categories, either general or subject-specific, that are combined to create the full classification entry. Many library classification systems use a combination of a fixed, enumerative taxonomy of concepts with subordinate facets that further refine the topic. Definition There are two primary types of classification used for information organization: enumerative and faceted. An enumerative classification contains a full set of entries for all concepts. A faceted classification system uses a set of semantically cohesive categories that are combined as needed to create an expression of a concept. In this way, the faceted classification is not limited to already defined concepts. While this makes the classification quite flexible, it also makes the resulting expression of topics complex. To the extent possible, facets represent "clearly defi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Classification Scheme
In information science and ontology, a classification scheme is the product of arranging things into kinds of things (classes) or into ''groups'' of classes; this bears similarity to categorization, but with perhaps a more theoretical bent, as classification can be applied over a wide semantic spectrum. In the abstract, the resulting structures are a crucial aspect of metadata, often represented as a hierarchical structure and accompanied by descriptive information of the classes or groups. Such a classification scheme is intended to be used for an arrangement or division of individual objects into the classes or groups, and the classes or groups are based on characteristics which the objects (members) have in common. The ISO/IEC 11179 metadata registry standard uses classification schemes as a way to classify administered items, such as data elements, in a metadata registry. Some quality criteria for classification schemes are: * Whether different kinds are grouped together. I ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
International Labour Organization
The International Labour Organization (ILO) is a United Nations agency whose mandate is to advance social and economic justice by setting international labour standards. Founded in October 1919 under the League of Nations, it is the first and oldest specialised agency of the UN. The ILO has 187 member states: 186 out of 193 UN member states plus the Cook Islands. It is headquartered in Geneva, Switzerland, with around 40 field offices around the world, and employs some 3,381 staff across 107 nations, of whom 1,698 work in technical cooperation programmes and projects. The ILO's standards are aimed at ensuring accessible, productive, and sustainable work worldwide in conditions of freedom, equity, security and dignity. They are set forth in 189 conventions and treaties, of which eight are classified as fundamental according to the 1998 Declaration on Fundamental Principles and Rights at Work; together they protect freedom of association and the effective recognition of the r ...

Tag (metadata)
In information systems, a tag is a keyword or term assigned to a piece of information (such as an Internet bookmark, multimedia, database record, or computer file). This kind of metadata helps describe an item and allows it to be found again by browsing or searching. Tags are generally chosen informally and personally by the item's creator or by its viewer, depending on the system, although they may also be chosen from a controlled vocabulary. Tagging was popularized by websites associated with Web 2.0 and is an important feature of many Web 2.0 services. It is now also part of other database systems, desktop applications, and operating systems. Overview People use tags to aid classification, mark ownership, note boundaries, and indicate online identity. Tags may take the form of words, images, or other identifying marks. An analogous example of tags in the physical world is museum object tagging. People were using textual keywords to classify information and objects long b ...

Information Architecture
Information architecture (IA) is the structural design of shared information environments; the art and science of organizing and labelling websites, intranets, online communities and software to support usability and findability; and an emerging community of practice focused on bringing principles of design, architecture and information science to the digital landscape. Typically, it involves a model or concept of information that is used and applied to activities which require explicit details of complex information systems. These activities include library systems and database development. Information management lies between data management and knowledge management. Data management focuses on handling individual pieces of data for example by using databases. Knowledge management focuses on information that exists within a humans mind, and how to extract and share this. Information Architecture is distinct from process management but there are often valuable interactions betw ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Folksonomy
Folksonomy is a classification system in which end users apply public tags to online items, typically to make those items easier for themselves or others to find later. Over time, this can give rise to a classification system based on those tags and how often they are applied or searched for, in contrast to a taxonomic classification designed by the owners of the content and specified when it is published. This practice is also known as collaborative tagging, social classification, social indexing, and social tagging. Folksonomy was originally "the result of personal free tagging of information ..for one's own retrieval", but online sharing and interaction expanded it into collaborative forms. ''Social tagging'' is the application of tags in an open online environment where the tags of other users are available to others. ''Collaborative tagging'' (also known as group tagging) is tagging performed by a group of users. This type of folksonomy is commonly used in cooperative and col ...

Findability
Findability is the ease with which information contained on a website can be found, both from outside the website (using search engines and the like) and by users already on the website. Although findability has relevance outside the World Wide Web, the term is usually used in that context. Most relevant websites do not come up in the top results because designers and engineers do not cater to the way ranking algorithms work currently. Its importance can be determined from the first law of e-commerce, which states "If the user can’t find the product, the user can’t buy the product." As of December 2014, out of 10.3 billion monthly Google searches by Internet users in the United States, an estimated 78% are made to research products and services online. Findability encompasses aspects of information architecture, user interface design, accessibility and search engine optimization (SEO), among others. Introduction Findability is similar to discoverability, which is defined as the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Faceted Search
Faceted search is a technique that involves augmenting traditional search techniques with a faceted navigation system, allowing users to narrow down search results by applying multiple filters based on faceted classification of the items. It is sometimes referred to as a '' parametric search'' technique. A faceted classification system classifies each information element along multiple explicit dimensions, called facets, enabling the classifications to be accessed and ordered in multiple ways rather than in a single, pre-determined, taxonomic order. Facets correspond to properties of the information elements. They are often derived by analysis of the text of an item using entity extraction techniques or from pre-existing fields in a database such as author, descriptor, language, and format. Thus, existing web-pages, product descriptions or online collections of articles can be augmented with navigational facets. Faceted search interfaces were first developed in the academic worl ...

Filter (software)
A filter is a computer program or subroutine to process a stream, producing another stream. While a single filter can be used individually, they are frequently strung together to form a pipeline. Some operating systems such as Unix are rich with filter programs. Windows 7 and later are also rich with filters, as they include Windows PowerShell. In comparison, however, few filters are built into cmd.exe (the original command-line interface of Windows), most of which have significant enhancements relative to the similar filter commands that were available in MS-DOS. OS X includes filters from its underlying Unix base but also has Automator, which allows filters (known as "Actions") to be strung together to form a pipeline. Unix In Unix and Unix-like operating systems, a filter is a program that gets most of its data from its standard input (the main input stream) and writes its main results to its standard output (the main output stream). Auxiliary input may come from command line ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Art And Architecture Thesaurus
The Art & Architecture Thesaurus (AAT) is a controlled vocabulary used for describing items of art, architecture, and material culture. The AAT contains generic terms, such as "cathedral," but no proper names, such as "Cathedral of Notre Dame." The AAT is used by, among others, museums, art libraries, archives, catalogers, and researchers in art and art history. The AAT is a thesaurus in compliance with ISO and NISO standards including ISO 2788, ISO 25964 and ANSI/NISO Z39.19. The AAT is a structured vocabulary of 55,661 concepts (as of January 2020), including 131,000 terms, descriptions, bibliographic citations, and other information relating to fine art, architecture, decorative arts, archival materials, and material culture. History The AAT project began in the late 1970s in response to the gradual automation of records by art libraries, art journal indexing services, and catalogers of museum objects and visual resources. Automation required consistency in cataloging as wel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Classification Research Group
The Classification Research Group (CRG) was a significant contributor to classification research and theory in the field of library and information science in the latter half of the 20th century. It was formed in England in 1952 and was active until 1968. Informal meetings continued until 1990. Among its members were Derek Austin, Eric Coates, Jason Farradane, Robert Fairthorne, Douglas Foskett, Barbara Kyle, Derek Langridge, Jack Mills, Pauline Atherton Cochrane, Bernard Palmer, Jack Wells, and Brian Campbell Vickery. The group formed important principles on faceted classification and also worked on the theory of integrative levels. Publications * 1955.
