We accept papers reporting original (unpublished) research of two types:

  • Long papers (max 8 pages + references)
  • Short papers (max 4 pages + references)

Appendices and acknowledgements do not count against the maximum page limit and should be formatted according to the guidelines below.

To submit a paper, please access the submission link.

Conference proceedings will be published on the ACL Anthology.

Non-archival option

The authors have the option of submitting previously unpublished research as non-archival, meaning that only the abstract will be published in the conference proceedings. We expect these submissions to describe the same quality of work as archival submissions. These will be reviewed following the same procedure as archival submissions. This option accommodates publication of the work or a superset at a later date in a conference or journal which does not allow previously archived work and to encourage presentation and feedback on mature, yet unpublished work. Non-archival submissions should adhere to the same formatting and length constraints as archival submissions.

Dual Submission and Pre-print Policy

Papers that have been or will be submitted to workshops, conferences or journals during the review period must indicate so at submission time. Authors of papers accepted for presentation at the NLLP 2021 workshop must notify the organizers by the camera-ready deadline as to whether the paper will be presented or withdrawn.

If the preliminary version of a paper was posted in arXiv, the authors should NOT mention it as their own paper in the submission. Papers that violate the double-blind review requirements will be desk rejected.

Exception: Submissions with the non-archival option are excepted from these requirements.

ACL Rolling Review

Starting from this year, our workshop also welcomes submissions from ACL Rolling Review (ARR). Authors of any papers that are submitted to ARR before July 15, 2021 and have their reviews ready may submit their papers and reviews for consideration for the workshop up to one week before our notification date i.e. before 3 September 2021.

Double-Blind reviewing

The review process is double-blind. Submitted papers must not include author names and affiliations and they must be written in a way so that they do not break the double-blind reviewing process. If the preliminary version of a paper was posted in arXiv, the authors should NOT mention it as their own paper in the submission. Papers that violate the double-blind review requirements will be desk rejected.

Submission Style & Format Guidelines

Submissions to the workshop must be in PDF and formatted according to the new Standard ACL Conference Proceedings Template.

The templates are available on Overleaf as a template and can also be downloaded directly (LaTeX, Word).

Please follow the formatting documentation general to *ACL conferences available here. The templates themselves contain only specific notes (e.g., LaTeX notes in the .tex file).

Papers that do not meet the formatting requirements will be rejected without review.
