hiponímia

Hiponímia is a linguistic term that describes a hierarchical relationship between words, specifically the relationship between a broader, more general term and a narrower, more specific term. The more general term is known as the hypernym, while the more specific term is the hyponym. For instance, "animal" is a hypernym of "dog," and "dog" is a hyponym of "animal." Similarly, "color" is a hypernym of "red," and "red" is a hyponym of "color." This relationship is transitive, meaning if "A" is a hyponym of "B," and "B" is a hyponym of "C," then "A" is also a hyponym of "C."

This concept is fundamental to understanding semantic fields and how words are organized in a lexicon. It plays a crucial role in natural language processing, information retrieval, and the construction of ontologies and knowledge graphs, where these hierarchical relationships are explicitly modeled. Recognizing hiponímia allows systems to infer meaning and establish connections between related concepts, enhancing their ability to understand and process human language. For example, if a system knows that "poodle" is a hyponym of "dog," and "dog" is a hyponym of "animal," it can infer that a poodle is also an animal. This is a key aspect of how humans organize knowledge and make sense of the world around them, and it's a principle that computational linguistics strives to replicate.
