MWE-WN 2019

The 15th edition of the yearly flagship event of the MWE Section, called Workshop on Multiword Expressions (MWE), was co-located with the ACL 2019 conference in Florence, Italy. In a quest for synergies with related communities, the Section joined forces with the Global Wordnet Association (GWA). Thus, the event was called Joint Workshop on Multiword Expressions and WordNet (MWE-WN 2019).

Invited talk: "When the whole is greater than the sum of its parts: Multiword expressions and idiomaticity", by Aline Villavicencio, University of Essex (UK) and Federal University of Rio Grande do Sul (Brazil)

Submissions: 37 papers (20 long and 17 short) were submitted. 12 long papers and 8 short ones were selected. 6 papers (1 short and 5 long) were selected as oral presentations and 14 (7 short and 7 long) as posters. The overall acceptance rate was 54%.

Proceedings: to appear in the ACL Anthology.

Community discussion: it will include feedback from this joint event, MWE-related announcements, announcements about the SIGLEX-MWE Steering Committee recruitment, plans for future shared task editions and for collaboration between the Universal Dependencies and the PARSEME communities.
