(2015), who try different ways of modulating the inclusion of perceptual input in their multi-modal skip-gram model, and find that the entropy of the centroid vector µ works well (where p(µ j ) = µ j || µ|| and m is the vector length): We calculate the directionality of a hyponymhypernym pair with a measure f using the following formula for a word pair (p, q).
examples of pairs in the respective datasets can be found in Table 1.
