Large-Scale Collection of English Antonym and Synonym Pairs across Word Classes

This dataset contains antonymous and synonymous pairs across adjective, noun and verb classes. These antonymous and synonymous pairs were collected from WordNet and Wordnik resources. The dataset was split into three sets of training, testing and validation with the proportion of 70%, 25%, and 5% respectively. The ratio of #antonyms and #synonyms in all sets is balance.
