In the first step of their two-step method, for each uni-modal concept k, a quasi-perceptual representation is computed as an average of the perceptual representations of bi-modal concepts, weighted by the proximity between each of these concepts and k whereC is the set of bi-modal concepts, c p and k p are the perceptual representations for c and k respectively, and c l and k l the linguistic representations.
we therefore investigated whether or not it is preferable to include this additional information as model input or to restrict perceptual input  to concrete nouns as previously.
