- A concept hierarchy is a tree where nodes correspond to concepts, and edges correspond to is-a relationships between concepts. The most concrete concepts reside at the leafs of the tree, while the most general concept, denoted `*', resides at the apex of the tree and represents any concept. The level of abstraction of a concept in the hierarchy is the level at which the concept is located in the tree.
