hyperonymer

Hyperonymer is a term used in linguistic semantics and computational linguistics to describe an agent that identifies, derives, or annotates hypernym relations in text. Hypernyms denote higher-level categories in a semantic hierarchy; for example, the hypernym of dog is animal. A hyperonymer can be a researcher, a software tool, or an annotation scheme used to map terms to their more general categories. The concept emphasizes the act of generating or applying hypernym relations rather than the relation itself.

Etymology and terminology: The term combines hyper- (above, over) with onym (name) and the agentive suffix -er. It is a neologism and not yet standardized in core glossaries, but it appears in discussions of semantic annotation, ontology construction, and hypernym extraction.

Applications: In natural language processing, a hyperonymer may be implemented as a hypernym extractor, annotating corpora with generalization relations drawn from lexical databases such as WordNet. For example, labeling "dog" with the hypernym "animal" or grouping "sparrow," "eagle," and "penguin" under the hypernym "bird." In linguistic research, the term can describe a method for testing how well a corpus reveals category hierarchies.

Relation to related terms: Hyperonymer is distinct from hypernym (the relation itself) and from hyponym (a more specific term). It is also related to taxonomy, ontology, and semantic role labeling.
