Paper submission

Submissions should be scientific papers or shared task system description papers. All papers may consist of 4 to 8 pages of content with additional pages of references, formatted using the ACL stylesheets. Upon acceptance, all papers will be given one (1) additional content page to address reviewers’ comments. Accepted papers will be published in the ACL 2022 proceedings and will be presented at the IWSLT conference either orally or as a poster.

  • Scientific papers must be anonymised for submission, while system description papers do not need to be.
  • Submissions which have previously been made available as technical reports or preprints, e.g. on arXiv, may be accepted.
  • Scientific papers for publication that overlap significantly in content or results with papers published elsewhere are not accepted.
  • Scientific papers which have been, or plan to be, submitted to other venues must be declared as such at the time of submission, and must be withdrawn from the other venues if accepted and published at IWSLT 2022.
