An Is-A-Type-Of Relation Mention Recognition Task is a relation recognition task that can recognize Is-A-Type-Of Relation Mentions.
- AKA: Subsumption Relation Mention Recognition, Hyponymy Relation Mention Recognition, Hypernym Relation Mention Recognition.
- Context:
- It can be an input to an Is-A-Type-Of Extraction Task.
- Example(s):
- Counter-Example(s):
- See: Hyponymy Relation, Meronymy Relation Mention, Hypernymy Relation.

- QUOTE: Hyponymy is a relation between two word senses, indicating that the meaning of one word is also contained in the other. It can be thought of as a type-of relation; for example car, ship and train are all hyponyms of vehicle. We denote a hyponymy relation between words [math]\displaystyle{ a }[/math] and [math]\displaystyle{ b }[/math] as ([math]\displaystyle{ a \rightarrow b }[/math]), showing that [math]\displaystyle{ a }[/math] is a hyponym of [math]\displaystyle{ b }[/math], and [math]\displaystyle{ b }[/math] is a hypernym of [math]\displaystyle{ a }[/math]. Hyponymy relations are closely related to the concept of entailment, and this notation is consistent with indicating the direction of inference – if [math]\displaystyle{ a }[/math] is true, [math]\displaystyle{ b }[/math] must be true as well.
Automatic detection and generation of hyponyms has many practical applications in nearly all natural language processing tasks. Information retrieval, information extraction and question answering can be improved by performing appropriate query expansions. For example, a user searching for arthritis treatment is most likely also interested in results containing the hyponyms of treatment, such as arthritis therapy, arthritis medication, and arthritis rehabilitation.
