  1. ToMMeR - Efficient Entity Mention Detection from Large Language Models
    Victor Morand, Nadi Tomeh, Josiane Mothe, Benjamin Piwowarski
    ACL2026linkdoi

    This work provides evidence that structured entity representations exist in early transformer layers and can be efficiently recovered with minimal parameters, and reveals that diverse architectures converge on similar mention boundaries, confirming that mention detection emerges naturally from language modeling
