SemanticRelation
SemanticRelation is a general term used in linguistics and natural language processing to denote a meaningful connection between two semantic units, such as words, phrases, concepts, or propositions. Such relations help encode how meanings of units relate to each other within a language, a knowledge graph, or an ontology. Semantic relations can be lexical, capturing relationships among words, or more abstract, linking concepts within a given domain.
Common lexical semantic relations include synonymy (similar meaning), antonymy (opposites), hyponymy and hypernymy (particular versus general),
Examples: car is a hypernym of sedan; sedan is a hyponym of car. Wheel is a meronym
Applications include knowledge graphs, search and information retrieval, question answering, machine translation, and ontology engineering. Semantic
