Negated Adjectives and Antonyms in Distributional Semantics: not similar?

We investigate the relation between negated adjectives and antonyms pairs in English (e.g., not cold vs. hot - cold) using Distributional Semantics. We build vector representations of a set of antonyms and their negations on the basis of their contexts of use, and compare the similarities of the neg...
