Only the regular workshop paper will be included in the proceedings. Submissions should be made to https://www.softconf.com/l/acl-workshops2021/. Selected papers will be invited to submit to a special session of the MDPI Information journal. Regular Workshop Papers ==================== Authors should submit a paper up to 4-8 pages long, with unlimited reference and supplementary material pages. The submission should follow the EMNLP 2021 style and formatting guidelines (ACL Policies for Submission, Review, and Citation). The papers should present novel research. Reviewing will be double-blind, so please do not include any self-identifying information in the submission. Double submission is allowed, but the paper accepted by another conference should be moved to cross-submissions. Extended Abstracts =============== Preliminary but interesting ideas that have not been published before may be submitted as extended abstracts. These should be up to 2 pages long and would benefit from additional exposure and discussion but are not ready for publication. Reviewing will be double-blind, so please do not include any self-identifying information in the submission. Selection of extended abstracts will be determined solely by the organizing committee. Cross-Submissions =============== In addition to previously unpublished work, we invite papers on relevant topics which have appeared in or submitted to alternative venues (such as other NLP or ML conferences). Accepted cross-submissions will be presented as posters, with an indication of the original venue. Selection of cross-submissions will be determined solely by the organizing committee.
