This property has led to the introduction of lexical entailment measures that compare the entropy of distributional word representations, under the assumption that a more general term has a higher-entropy distribution (Herbelot and Ganesalingam, 2013;Santus et al., 2014).
since even cohyponyms will not have identical values for f , we introduce a threshold α which sets a minimum difference in generality for hypernym identification: s(p, q) > 0 iff f (q) > f (p) + α, i.e.
