A new research paper published on arXiv details how multilingual language models struggle with entity matching when names are presented in different scripts. The study found that models like Qwen2.5-7B exhibit significantly lower accuracy in identifying the same person when their name is in Devanagari script compared to Latin script, particularly in Marathi and Malayalam prompts. Researchers identified that while tokenization fragmentation is not the primary cause, scalar calibration and specific middle-layer activations in the model are critical factors contributing to this script-dependent discrimination, suggesting targeted interventions could improve cross-script identity judgments.
