Classification Scheme - Kinds of Classification Schemes

Kinds of Classification Schemes

The following are examples of different kinds of classification schemes. This list is in approximate order from informal to more formal:

  • thesaurus - a collection of categorized concepts, denoted by words or phrases, that are related to each other by narrower term, wider term and related term relations.
  • taxonomy - a formal list of concepts, denoted by controlled words or phrases, arranged from abstract to specific, related by subtype-supertype relations or by superset-subset relations.
  • data model - an arrangement of concepts (entity types), denoted by words or phrases, that have various kinds of relationships. Typically, but not necessarily, representing requirements and capabilities for a specific scope (application area).
  • network (mathematics) - an arrangement of objects in a random graph.
  • ontology - an arrangement of concepts that are related by various well defined kinds of relations. The arrangement can be visualized in a directed acyclic graph.

One example of a classification scheme for data elements is a representation term.

Famous quotes containing the words kinds of, schemes and/or kinds:

    There are two kinds of truth; the truth that lights the way and the truth that warms the heart. The first of these is science, and the second is art.... Without art science would be as useless as a pair of high forceps in the hands of a plumber. Without science art would become a crude mess of folklore and emotional quackery.
    Raymond Chandler (1888–1959)

    Science is a dynamic undertaking directed to lowering the degree of the empiricism involved in solving problems; or, if you prefer, science is a process of fabricating a web of interconnected concepts and conceptual schemes arising from experiments and observations and fruitful of further experiments and observations.
    James Conant (1893–1978)

    Among all kinds of Writing, there is none in which Authors are more apt to miscarry than in Works of Humour, as there is none in which they are more ambitious to excel.
    Joseph Addison (1672–1719)
