Meeting Description:

MWE-LEX 2020 will host edition 1.2 of the PARSEME shared task on semi-supervised identification of verbal MWEs. This is a follow-up of editions 1.0 (2017), and 1.1 (2018). The latter covered 20 languages and received 17 submissions by 12 teams. Edition 1.2 will feature (a) improved and extended corpora annotated with MWEs, (b) complementary unannotated corpora for unsupervised MWE discovery, and (c) new evaluation metrics focusing on unseen MWEs. Following the synergy with Elexis, our aim is to foster the development of unsupervised methods for MWE lexicon induction, which in turn can be used for identification. Authors may submit system description papers to a special track, following common submission guidelines. Details will be available here soon.
