HyperLex is a gold standard resource for measuring and evaluating how well semantic models capture graded or soft lexical entailment (also known as the type-of, is-a, or hypernymy-hyponymy relation) rather than semantic similarity or relatedness. It quantifies the extent of the semantic category membership and lexical entailment (LE) relation.
We provide 2616 word pairs (2163 noun pairs and 453 verb pairs) with ratings on a scale 0-10, annotated according to the question: "To what degree is X a type of Y?". Here are some examples:
|girl / person||9.85|
|citizen / person||8.63|
|person / citizen||5.17|
|idol / person||4.28|
|plant / person||0.42|
|to talk / to communicate||9.25|
|to pray / to communicate||4.83|
HyperLex covers plenty of normed word types from the USF free-association database, and provides annotated examples of different WordNet-based lexical relations (i.e., hyponymy-hypernymy at different levels, co-hyponymy, synonymy, antonymy, meronymy-holonymy, no-relation). it also contains examples of different concreteness levels.
