What is Taxonomy?

By   /  August 14, 2017  /  No Comments

taxonomyTaxonomy represents the formal structure of classes or types of objects within a domain. It organizes knowledge by using a controlled vocabulary to make it easier to find related information. A Taxonomy must:

  • Follow a hierarchic format and provides names for each object in relation to other objects.
  • May also capture the membership properties of each object in relation to other objects.
  • Have specific rules used to classify or categorize any object in a domain. These rules must be complete, consistent, and unambiguous.
  • Apply rigor in specification, ensuring any newly discovered object must fit into one and only one category or object.
  • Inherit all the properties of the class above it, but can also have additional properties.

Other Definitions of Taxonomy Include:

  • “Taxonomy is a set of chosen terms use to retrieve on-line content – to make the search and browse capabilities of the content, document or records management systems truly functional.” (Computer Weekly)
  • “Taxonomy is a Knowledge Organization System (KOS) or a set of elements, often structured and controlled, which can be used for describing (indexing) objects, browsing collections etc.” (W3C org)
  • “Taxonomy is a classification of products.” (Forbes)
  • “Taxonomy is a curated classification and nomenclature for all of the organisms in the public sequence database.” (NCBI)

Businesses apply Taxonomies to:

  • Achieve better Data Quality.
  • Organize Metadata in an easy grasp format (e.g. a Website map).
  • Manage data assets through Data Governance.
  • Make it easier for a Data Steward to curate information.
  • Guide Machine Learning and Data Experiences towards identifying trends and patterns.

Finding a book or document in a library or a specific website in a browser like Google, requires taxonomies, as does using a thesaurus.

While Taxonomies may differ across domains or Ontologies, they remain consistent in a specific representation (e.g. a business, department, or subject area):
