G-IdiomAlign - Multiple-Choice Equivalence: leaderboard
G-IdiomAlign (Ye et al., 2026) tests cross-lingual idiom alignment over Wiktionary idioms in nine languages. Given a source idiom, the model picks the meaning-equivalent target-language idiom among four options whose three distractors are a literal translation, a lexical look-alike and a contextually associated idiom; accuracy in percent (higher is better), macro-averaged over 30 translation directions.
Metric: Accuracy (%; source idiom to its meaning-equivalent target-language idiom among four options, the other three typed distractors (literal translation, lexical cue, contextual association), greedy decoding; macro-average over all 30 directions). Source: arxiv.org. Saturation forecast: Around February 2027. 7 models tracked.
