Hierarchy generation for numerical data

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.
