Integrating Distributional Lexical Contrast into Word Embeddings for Antonym–Synonym Distinction
Table 1: AP evaluation on DSMs.
['[EMPTY]', '[BOLD] Adjectives ANT', '[BOLD] Adjectives SYN', '[BOLD] Nouns ANT', '[BOLD] Nouns SYN', '[BOLD] Verbs ANT', '[BOLD] Verbs SYN']
In order to evaluate the distribution of word pairs with AP, we sorted the synonymous and antonymous pairs by their cosine scores. A synonymous pair was considered correct if it belonged to the first half; and an antonymous pairs was considered correct if it was in the second half. The optimal results would thus achieve an AP score of 1 for SYN and 0 for ANT.
