Knowing the degree of antonymy between words has widespread applications in natural language processing. Manually-created lexi- cons have limited coverage and do not include most semantically contrasting word pairs. We present a new automatic and empirical mea- sure of antonymy that combines corpus statis- tics with the structure of a published the- saurus. The approach is evaluated on a set of closest-opposite questions, obtaining a preci- sion of over 80%. Along the way, we discuss what humans consider antonymous and how antonymy manifests itself in utterances.
