Wikipedia Meaning and Definition on 'Hyponymy'
In linguistics, a hyponym is a word or phrase whose semantic field
Computer science often terms this relationship an "is-a" relationship. For example, the phrase Red is a colour can be used to describe the hyponymic relationship between red and colour.
Hypernymy is the semantic relation in which one word is the hypernym of another. Hypernymy, the relation in which words stand when their extensions stand in the relation of class to subclass, should not be confused with holonymy, which is the relation in which words stand when the things that they denote stand in the relation of whole to part. A similar warning applies to hyponymy and meronymy.
Hypernym/hyponym pairs can be found in text corpora by looking for certain syntactic patterns. One of the first suggestions on how to find hypernym/hyponym pairs in a text came from Marti Hearst, who suggested looking at the output of a parser and taking all of the terms linked by constructions such as X and other Y; X could be considered a possible hyponym of Y. This method was extended by Snow et al., who developed an automated method of finding possible constructions that could signal such a pair.[See more about Hyponymy at Dictionary 3.0 Encyclopedia]
