PAPER SUBMISSION INFORMATION
Long Papers
Long
paper submissions must describe substantial, original, completed and
unpublished work. Wherever appropriate, concrete evaluation and analysis
should be included. Review forms will be made available prior to the
deadlines. Long papers may consist of up to 8 pages of content, plus
unlimited pages for references; final versions of long papers will be
given one additional page of content (up to 9 pages) so that reviewers’
comments can be taken into account.
Long papers will be presented
orally or as posters as determined by the program committee. The
decisions as to which papers will be presented orally and which as
poster presentations will be based on the nature rather than the quality
of the work. There will be no distinction in the proceedings between
long papers presented orally and as posters.
Short Papers
Short
paper submissions must describe original and unpublished work. Please
note that a short paper is not a shortened long paper. Instead short
papers should have a point that can be made in a few pages. Some kinds
of short papers are:
A small, focused contribution
A negative result
An opinion piece
An interesting application nugget
Short
papers may consist of up to 4 pages of content, plus unlimited
references. Upon acceptance, short papers will be given 5 content pages
in the proceedings. Authors are encouraged to use this additional page
to address reviewers’ comments in their final versions.
Short papers
will be presented orally or as posters as determined by the program
committee. While short papers will be distinguished from long papers in
the proceedings, there will be no distinction in the proceedings between
short papers presented orally and as posters.
Authorship
The
author list for submissions should include all (and only) individuals
who made substantial contributions to the work presented. Each author
listed on a submission to EMNLP 2021 will be notified of submissions,
revisions and the final decision. No changes to the order or composition
of authorship may be made to submissions to EMNLP 2021 after the
abstract submission deadline.
Citation and Comparison
You
are expected to cite all refereed publications relevant to your
submission, but you may be excused for not knowing about all unpublished
work (especially work that has been recently posted and/or is not
widely cited).
In cases where a preprint has been superseded by a
refereed publication, the refereed publication should be cited instead
of the preprint version.
Papers (whether refereed or
not) appearing less than 3 months before the submission deadline are
considered contemporaneous to your submission, and you are therefore not
obliged to make detailed comparisons that require additional
experimentation and/or in-depth analysis.
For more information, see the ACL Policies for Submission, Review, and Citation
Multiple Submission Policy
EMNLP
2021 will not consider any paper that is under review in a journal or
another conference at the time of submission, and submitted papers must
not be submitted elsewhere during the EMNLP 2021 review period. This
policy covers all refereed and archival conferences and workshops (e.g.,
NeurIPS, ACL workshops).
In addition, we will not consider any paper
that overlaps significantly in content or results with papers that will
be (or have been) published elsewhere. Authors submitting more than one
paper to EMNLP 2021 must ensure that their submissions do not overlap
significantly (>25%) with each other in content or results.
Ethics Policy
Authors
are required to honour the ethical code set out in the ACL Code of
Ethics. The consideration of the ethical impact of our research, use of
data, and potential applications of our work has always been an
important consideration, and as artificial intelligence is becoming more
mainstream, these issues are increasingly pertinent. We ask that all
authors read the code, and ensure that their work is conformant to this
code. Where a paper may raise ethical issues, we ask that you include in
the paper an explicit discussion of these issues, which will be taken
into account in the review process. We reserve the right to reject
papers on ethical grounds, where the authors are judged to have operated
counter to the code of ethics, or have inadequately addressed
legitimate ethical concerns with their work.
Paper Submission and Templates
Submission
is electronic, using the Softconf START conference management system.
Both long and short papers must follow the EMNLP 2021 two-column format,
using the supplied official style sheets (to be provided later). Please
do not modify these style files, nor should you use templates designed
for other conferences. Submissions that do not conform to the required
styles, including paper size, margin width, and font size restrictions,
will be rejected without review.
Optional Supplementary Materials: Appendices, Software and Data
Each
EMNLP 2021 submission can be accompanied by one PDF appendix for the
paper, one PDF for prior reviews and author response, one .tgz or .zip
archive containing software, and one.tgz or .zip archive containing
data. EMNLP 2021 encourages the submission of these supplementary
materials to improve the reproducibility of results, and to enable
authors to provide additional information that does not fit in the
paper. For example, anonymised related work (see above), preprocessing
decisions, model parameters, feature templates, lengthy proofs or
derivations, pseudocode, sample system inputs/outputs, and other details
that are necessary for the exact replication of the work described in
the paper can be put into the appendix. However, the paper submissions
need to remain fully self-contained, as these supplementary materials
are completely optional, and reviewers are not even asked to review or
download them. If the pseudo-code or derivations or model specifications
are an important part of the contribution, or if they are important for
the reviewers to assess the technical correctness of the work, they
should be a part of the main paper, and not appear in the appendix.
Supplementary materials need to be fully anonymized to preserve the
double-blind reviewing policy.
ANONYMITY PERIOD
The
following rules and guidelines are meant to protect the integrity of
double-blind review and ensure that submissions are reviewed fairly. The
rules make reference to the anonymity period, which runs from 1 month
before the submission deadline (starting April 17th, 2021) up to the
date when your paper is accepted or rejected (August 25th, 2021). Papers
that are withdrawn during this period will no longer be subject to
these rules.
You may not make a non-anonymized version
of your paper available online to the general community (for example,
via a preprint server) during the anonymity period. Versions of the
paper include papers having essentially the same scientific content but
possibly differing in minor details (including title and structure)
and/or in length.
If you have posted a non-anonymized version of your
paper online before the start of the anonymity period, you may submit
an anonymized version to the conference. The submitted version must not
refer to the non-anonymized version, and you must inform the programme
chairs that a non-anonymized version exists.
You may not update the
non-anonymized version during the anonymity period, and we ask you not
to advertise it on social media or take other actions that would further
compromise double-blind reviewing during the anonymity period.
You may make an anonymized version of your paper available (for example, on OpenReview), even during the anonymity period.
Note
that, while you are not prohibited from making a non-anonymous version
available online before the start of the anonymity period, this does
make double-blind reviewing more difficult to maintain, and we therefore
encourage you to wait until the end of the anonymity period.
Alternatively, you may consider submitting your work to the
Computational Linguistics journal, which does not require anonymization
and has a track for “short” (i.e., conference-length) papers.
INSTRUCTIONS FOR DOUBLE-BLIND REVIEW
As
reviewing will be double blind, papers must not include authors’ names
and affiliations. Furthermore, self-references or links (such as github)
that reveal the author’s identity, e.g., “We previously showed (Smith,
1991) …” must be avoided. Instead, use citations such as “Smith
previously showed (Smith, 1991) …” Papers that do not conform to these
requirements will be rejected without review.
Papers should not
refer, for further detail, to documents that are not available to the
reviewers. For example, do not omit or redact important citation
information to preserve anonymity. Instead, use third person or named
reference to this work, as described above (“Smith showed” rather than
“we showed”). If important citations are not available to reviewers
(e.g., awaiting publication), these paper/s should be anonymised and
included in the appendix. They can then be referenced from the
submission without compromising anonymity.
Papers may
be accompanied by a resource (software and/or data) described in the
paper, but these resources should also be anonymized.
REPRODUCIBILITY CRITERIA
During
the submission process, authors will be asked to answer the questions
from the Reproducibility Checklist. The checklist is intended as a
reminder to help the authors improve reproducibility of their papers.
The papers are not required to meet all reproducibility criteria listed.
However, the answers will be made available to the reviewers. Reviewers
will be asked to assess the reproducibility of the work as part of
their reviews.
PRESENTATION REQUIREMENT
All accepted
papers must be presented at the conference to appear in the proceedings.
Authors of papers accepted for presentation at EMNLP 2021 must notify
the program chairs by the camera-ready deadline if they wish to withdraw
the paper.
At least one author of each accepted paper must register for EMNLP 2021 by the early registration deadline.
