Abstract:

Antonyms are words that have opposite or contrasting meanings in a specific domain [1]. For example, “asleep” is the
opposite of “awake” in the domain of “physical property” and they are considered complementary antonyms without
middle ground, while “long” is the opposite of “short” in the domain of “size” and they are considered scalar antonyms
with levels of comparison. Antonyms are essential for many NLP applications, such as negation detection,
paraphrasing, contradiction detecting, question answering, machine translation, sentiment analysis, information
retrieval and textual inference. There are no publicly available comprehensive antonym lists. Accordingly, our
objective is to develop a systematic approach to generate antonyms in the SPECIALIST Lexicon (thereafter, the
Lexicon) and hope to provide generic and comprehensive antonym features needed for the NLP community.
