Task 7: RumourEval 2019: Determining Rumour Veracity and Support for Rumours Task 8: Fact Checking in Community Question Answering Forums

Information extraction and question answering

Task 9: Suggestion Mining from Online Reviews and Forums Task 10: Math Question Answering

NLP for scientific applications

Task 12: Toponym Resolution in Scientific Papers

The proceedings contain both Task Description papers that describe each of the above tasks, and System Description papers that present the systems that participated in these tasks. A total of 11 task description papers and 223 system description papers are included in the proceedings.

SemEval 2020 32 task proposals were received and reviewed by 68 external reviewers from the ACL community. 12 of the tasks were selected for SemEval 2020. For more details about the event, check out http://alt.qcri.org/semeval2020/

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.
