Taxonomy depth

Taxonomies have different “levels”. The level of depth of a taxonomy refers to how deep the classifications of data can go. At the very least a taxonomy is two levels deep. In a taxonomy that is two levels deep, there is a simple classification and the words that are classified. In a three level taxonomy there is a classification and a classification of the classification. In an “n” level taxonomy, the classification process can continue as deeply as the analyst wishes. There is no theoretical limit to the depth of an n level taxonomy. There are of course practical limitations. Fig 4.3 depicts a two level, a three level and an n level taxonomy.
