A Uniform Approach to Analogies, Synonyms, Antonyms, and Associations

By Peter D. Turney


Recognizing analogies, synonyms, antonyms, and associations appear to be four\ud distinct tasks, requiring distinct NLP algorithms. In the past, the four\ud tasks have been treated independently, using a wide variety of algorithms.\ud These four semantic classes, however, are a tiny sample of the full\ud range of semantic phenomena, and we cannot afford to create ad hoc algorithms\ud for each semantic phenomenon; we need to seek a unified approach.\ud We propose to subsume a broad range of phenomena under analogies.\ud To limit the scope of this paper, we restrict our attention to the subsumption\ud of synonyms, antonyms, and associations. We introduce a supervised corpus-based\ud machine learning algorithm for classifying analogous word pairs, and we\ud show that it can solve multiple-choice SAT analogy questions, TOEFL\ud synonym questions, ESL synonym-antonym questions, and similar-associated-both\ud questions from cognitive psychology
