study review of multilingual evaluation set contamination

Cross-language benchmark studies increasingly flag contamination and overlap issues that inflate apparent gains in multilingual model comparisons (ACL anthology).

evidence map

• Data overlap is harder to detect in translated corpora.
• Low-resource language sets are especially vulnerable.
• Contamination weakens policy decisions based on benchmark rank.

method boundary

Robust multilingual evaluation needs stronger provenance checks and contamination audits.

my take

Without contamination controls, multilingual benchmark progress is partly narrative.
