Deadline: April 26, 2021

The 6th Workshop on Representation Learning for NLP (RepL4NLP-2021), co-located with ACL 2021 in Bangkok, Thailand, invites papers of a theoretical or experimental nature describing recent advances in vector space models of meaning, compositionality, and the application of deep neural networks and spectral methods to NLP.

We encourage submissions in the following topics, including but not limited to:

-

Developing new representations: at the document, sentence, word, or sub-word level, using language model objectives, word embeddings, spectral methods, etc. -

Evaluating existing representations: probing representations for generalization, compositionality & robustness, adversarial evaluation, analysis of representations. -

Efficient learning and inference: with respect to training and inference time, model size, amount of training data, etc.

-

Beyond English / text: multi-modal, cross-lingual, knowledge-informed embeddings, structure-informed embeddings (syntax, morphology), etc.

Important Dates

Submission deadline: April 26, 2021 -

Notification of acceptance: May 28, 2021 -

Camera-ready papers due: June 7, 2021 -

Workshop: August 5-6, 2021

All deadlines are 11:59 pm UTC -12h ("anywhere on Earth").

Submissions

We solicit three categories of papers: regular workshop papers, extended abstracts and cross-submissions. Only regular workshop papers will be included in the proceedings as archival publications, and only regular workshop papers will be eligible for best paper prizes. All three categories of papers may be long (maximum 8 pages plus references) or short (maximum 4 pages plus references). All submissions should be in PDF format and made through the Softconf website set up for this workshop: https://www.softconf.com/acl2021/RepL4NLP/ https://www.softconf.com/acl2021/w15_repl4nlp2021/.

In line with the ACL main conference policy, camera-ready versions of papers will be given one additional page of content, and no limit to additional pages for references.\

Regular Workshop Papers

Authors should submit a long paper of up to 8 pages, or a short paper of up to 4 pages, both with unlimited references, following the ACL 2021 formatting requirements (see the ACL 2021 Call For Papers for reference: https://2021.aclweb.org/calls/papers/). The reported research should be substantially original. Accepted papers will be presented as posters. Reviewing will be double-blind, and thus no author information should be included in the papers; self-reference that identifies the authors should be avoided or anonymized. Accepted papers will appear in the workshop proceedings.

Supplementary Material: Each submission can be accompanied by a single PDF appendix. 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. Supplementary materials need to be fully anonymized to preserve the double-blind reviewing policy.

Extended Abstracts

Preliminary but interesting ideas or results that have not been published before may be submitted as extended abstracts. Accepted extended abstracts will be presented as posters, and included in the workshop program and handbook, but will not be included in the workshop proceedings (and are not eligible for best paper prizes).

Extended abstract submissions are therefore ideal for preliminary work which would benefit from exposure but is not ready for publication. Authors should submit a long extended abstract of up to 8 pages, or a short extended abstract of up to 4 pages, both with unlimited references. Submissions should follow the ACL 2021 formatting requirements (see the ACL 2021 Call For Papers for reference: https://2021.aclweb.org/calls/papers/). Reviewing will be double-blind, and thus no author information should be included in the papers; self-reference that identifies the authors should be avoided or anonymized.

Cross-Submissions

In addition to previously unpublished work, we also solicit recent papers on relevant topics that have appeared in a non-NLP venue (e.g., workshop or conference papers at NeurIPS or ICML). Accepted cross-submissions will be presented as posters, with an indication of original venue, but will not be included in the workshop program and handbook, or the workshop proceedings (and are not eligible for best paper prizes). Cross-submissions are ideal for related work which would benefit from exposure to the RepL4NLP audience. Submission length is determined by the original venue. Interested authors should submit their papers in PDF format through the RepL4NLP Softconf website (https://www.softconf.com/acl2021/w15_repl4nlp2021/), with a note on the original venue. Papers in this category do not need to follow the ACL format and selection will be solely determined by the organizing committee.

Best Paper Prizes
