"The term classification can apply to one or all of:
the process of classifying (distinguishing and distribution kinds of "things" into different groups)
a resulting set of classes (also called "a classification system")
the assignment of elements to pre-established classes
Classifying - in the broad meaning given above - is a fundamental concept and a part of almost all kinds of activities.
Classification itself is an interdisciplinary field of study. Important contributing disciplines include philosophy, biology, knowledge organization, psychology, statistics and mathematics." - (en.wikipedia.org 22.10.2021)
