Hierarchical classification is a system of grouping things according to a hierarchy. [ 1 ] In the field of machine learning , hierarchical classification is sometimes referred to as instance space decomposition , [ 2 ] which splits a complete multi-class problem into a set of smaller classification problems.
The descriptors or subject headings are arranged in a hierarchy. A given descriptor may appear at several locations in the hierarchical tree. The tree locations carry systematic labels known as tree numbers, and consequently one descriptor can carry several tree numbers. For example, the descriptor "Digestive System Neoplasms" has the tree ...

Another feature of statistical classifications is the provision of residual categories for "other" and "unspecified" conditions that do not have a specific category in the particular classification. In a nomenclature there is a separate listing and code for every clinical concept. So, in the previous example, each of the tachycardia listed ...
Hierarchy is an important concept in a wide variety of fields, such as architecture, philosophy, design, mathematics, computer science, organizational theory, systems theory, systematic biology, and the social sciences (especially political science).
Categories are distinct collections of concrete or abstract instances (category members) that are considered equivalent by the cognitive system. Using category knowledge requires one to access mental representations that define the core features of category members (cognitive psychologists refer to these category-specific mental representations as concepts).
When placing list pages in such a category, use a sort key to adjust the page title to exclude the starting words "List of", or all lists would appear under "L". For example, when adding List of Soviet Republics to the category, using [[Category:Lists of countries|Soviet Republics, List of]] and will make it be sorted in the S section.
