bottomrelated

Bottomrelated is a neologism used in information science and related disciplines to describe a type of relationship or mapping that anchors to the bottom, or most specific, elements within a hierarchical structure or graph.

The term combines "bottom" and "related" to signal a focus on leaf-level categories, leaf nodes, or terminal concepts in a taxonomy or ontology. Because it is not a widely standardized term, its exact definition varies by context.

In taxonomy and cataloging, bottomrelated mapping links items to the most specific category available, enabling fine-grained retrieval but potentially increasing sparsity and fragmentation.

In knowledge graphs and recommender systems, bottomrelated connections may refer to associations anchored at the most specific entities, as opposed to general, top-level groupings.

Status: The term is not recognized as a formal concept in major thesauri or standards. It appears mainly in niche discussions, early-stage research, or informal documentation; readers should verify context before applying it.
