Dear colleagues,
We are excited to announce the third edition of the Shared Task on Multilingual Coreference Resolution! The focus of the task is learning models for prediction of coreference across a range of typologically different languages. Both identification of mentions and clustering of mentions that refer to the same entity are included. This year, we make a special focus on identification of zeros (e.g. zero subjects, objects, ellipses). However, we don't mean it as a limitation. You can participate just for selected languages and without dealing with zero mentions.
