Classification (science de l'information)

A library classification is system of organization of knowledge in which sources are arranged according to the classification scheme and ordered very systematically. Library classifications are a notational system that represents the order of topics in the classification and allows items to be stored in the order of classification. Library classification systems group related materials together, typically arranged as a hierarchical tree structure. A different kind of classification system, called a faceted classification system, is also widely used, which allows the assignment of multiple classifications to an object, enabling the classifications to be ordered in many ways. Library classification is an important and crucial aspect in library and information science. It is distinct from scientific classification in that it has as its goal to provide a useful ordering of documents rather than a theoretical organization of knowledge. Although it has the practical purpose of creating a physical ordering of documents, it does generally attempt to adhere to accepted scientific knowledge. Library classification helps to accommodate all the newly published literature in an already created order of arrangement in a filial sequence. Library classification can be defined as the arrangement of books on shelves, or description of them, in the manner which is most useful to those who read with the ultimate aim of grouping similar things together. Library classification is meant to achieve these four purposes: ordering the fields of knowledge in a systematic way, bring related items together in the most helpful sequence, provide orderly access on the shelf, and provide a location for an item on the shelf. Library classification is distinct from the application of subject headings in that classification organizes knowledge into a systematic order, while subject headings provide access to intellectual materials through vocabulary terms that may or may not be organized as a knowledge system.

Les classifications bibliographiques, telles que celles mises en œuvre dans les bibliothèques, ont été les premiers outils d'organisation thématique des ouvrages. Ces systèmes de classification « permettent de représenter de façon synthétique le sujet d'un document, et de regrouper les ouvrages sur les rayons par affinité de contenu ».

Knowledge organization (KO), organization of knowledge, organization of information, or information organization, is an intellectual discipline concerned with activities such as document description, indexing, and classification that serve to provide systems of representation and order for knowledge and information objects. According to The Organization of Information by Joudrey and Taylor, information organization: examines the activities carried out and tools used by people who work in places that accumulate information resources (e.

La classification décimale de Dewey (CDD) est un système visant à classer l’ensemble du fonds documentaire d’une bibliothèque, développé en 1876 par Melvil Dewey, un bibliographe américain. Elle a été complétée et perfectionnée par la classification décimale universelle (CDU) développée par Henri La Fontaine et Paul Otlet. Les dix classes retenues par la classification de Dewey correspondent à neuf disciplines fondamentales : philosophie, religion, sciences sociales, langues, sciences pures, techniques, beaux-arts et loisirs, littératures, géographie et histoire, auxquelles s’ajoute une classe « généralités ».
