Members SIGLEX currently has 359 members. SIGLEX has two sections: Multiword Expressions (MWE) with 276 members, and SemEval with 240 members. In 2020/2021, we conducted an update in the membership registrations, asking members to re-register, update their section membership, (optionally) opt-in for displaying their names on the SIGLEX site, and (optionally) opt-in to emails from the mailing list.

Websites and mailing lists We updated the SIGLEX website and the mailing lists. The website https://siglex.org/ is now backed by https://github.com/acl-org/siglex/. The mailing lists are now backed by Google Groups at https://groups.google.com/g/siglex-members/ and siglex-board@googlegroups.com. The new website and mailing lists for SIGLEX are maintained by Steven Bethard. The MWE section of SIGLEX updated their website and the mailing list following a similar process. The website https://multiword.org/ is now backed by https://github.com/multiword/multiword.github.io. The mailing lists are now backed by Google Groups at https://groups.google.com/g/siglex-mwe-members and siglex-mwe-board@googlegroups.com. The new website and mailing lists for the MWE section of SIGLEX are maintained by Carlos Ramisch. The SemEval section of SIGLEX continues to be managed by the SemEval organizers (currently Alexis Palmer, Nathan Schneider, Guy Emerson, and Natalie Schluter) using the existing website, https://semeval.github.io/, and the mailing list, semeval-organizers@googlegroups.com.

Lexical semantics Task 1: Lexical Complexity Prediction Task 2: Multilingual and Cross-lingual Word-in-Context Disambiguation Task 4: Reading Comprehension of Abstract Meaning

Social factors & opinion Task 5: Toxic Spans Detection Task 6: Detection of Persuasive Techniques in Texts and Images Task 7: HaHackathon: Detecting and Rating Humor and Offense

Information in scientific & clinical text Task 8: MeasEval: Counts and Measurements Task 9: Statement Verification and Evidence Finding with Tables Task 10: Source-Free Domain Adaptation for Semantic Processing Task 11: NLPContributionGraph

Other phenomena Task 12: Learning with Disagreements

The proceedings contain both task description papers for each of the above tasks, and system description papers describig the systems that participated in these tasks. A total of 11 task description papers and 175 system description papers are included in the proceedings.

SemEval 2022 A total of 12 tasks were selected for SemEval 2022. They will be announced at the SemEval 2021 workshop. For more details about the event, check https://semeval.github.io/SemEval2022/
