We invite you to participate in the Shared Task on Multilingual Coreference Resolution, the results of which will be presented at CRAC 2024 https://sites.google.com/view/crac2024/ (The 7th Workshop on Computational Models of Reference, Anaphora and Coreference) at EMNLP 2024 https://2024.emnlp.org/ .

The shared task participants are supposed to create systems that:

* identify mentions in texts, including reconstruction of zero mentions, i.e. empty tokens (such as pro-drops) involved in coreference relations, * identify coreference relations between the mentions, i.e. predict which mentions belong to the same coreference cluster (i.e., refer to the same entity or event).

Please refer to the Shared Task website https://ufal.mff.cuni.cz/corefud/crac24 for full details.
