IWPT 2021 Shared Task on Parsing into Enhanced Universal Dependencies

Universal Dependencies (UD) is a framework for cross-linguistically consistent treebank annotation that has so far been applied to over 100 languages. In 2017 and 2018 there were two CoNLL shared tasks on UD parsing. In 2020 there was the first shared task on parsing enhanced UD, organized as a part of IWPT 2020. The current task is second in a row, organized as a part of the 17th International Conference on Parsing Technologies (IWPT), to be collocated with ACL-IJCNLP 2021 in Bangkok, Thailand (now planned as a virtual on-line event).

UD defines two levels of annotation, the basic trees and the enhanced graphs (EUD). While the CoNLL tasks evaluated morphology and basic dependency prediction on the UD data, the current task’s focus is on the enhanced dependency representation. The evaluation will be done on datasets in 17 languages from 4 language families.
