"WebTraditionally, these hierarchies were created by the data owner with help from the domain experts. But while it is feasible to construct a hierarchy of small size, the effort increases for hierarchies that have many levels. Therefore, new approaches of creating these numerical hierarchies involve their automatic/on-the-fly generation. " - Hierarchy generation for numerical data

A concept hierarchy represents a sequence of mappings with a set of more general concepts to specialized concepts. Similarly mapping from low-level concepts to higher-level concepts. In other words, we can say top-down mapping and bottom-up mapping.
