The Third Workshop on Evaluating Vector Space Representations for NLP
June 6th 2019, Minneapolis (USA)
(co-located with NAACL)
General-purpose dense word embeddings have come a long way since the beginning of their boom in 2013, and they are still the most widely used way of representing words in both industrial and academic NLP systems. However, the issue of intrinsic metrics that are predictive of performance on downstream tasks, and can help to develop better representations, is far from being solved. At the sentence level and above, we now have a number of probing tasks and large extrinsic evaluation datasets targeting high-level verbal reasoning, but there is still much to learn about what features make a compositional representation successful. Last but not the least, there are no established intrinsic methods for newer kinds of representations such as ELMO, BERT, or box embeddings.
The third edition of RepEval aims to foster discussion of the above issues, and to support the search for high-quality general purpose representation learning techniques for NLP. We hope to encourage interdisciplinary dialogue by welcoming diverse perspectives on the above issues: submissions may focus on properties of embedding space, performance analysis for various downstream tasks, as well as approaches based on linguistic and psychological data. In particular, experts from the latter fields are encouraged to contribute analysis of claims previously made in NLP community.
RepEval 2019 invites submissions including, but not limited to the following issues:
Research paper submissions may consist of 4-6 pages of content, plus unlimited references. An additional page in the camera-ready version will be available for addressing reviewers’ comments. Please refer to the NAACL author guidelines for the style files, policy on double submissions and preprints: https://naacl2019.org/calls/papers/#author-guidelines
We invite proposals for new evaluation techniques for old and new representations; the submissions are expected to experimentally demonstrate the benefits of the new approach. Submissions may also contribute critical analysis and/or negative results for the existing approaches.
We welcome both theoretical analysis (especially from experts in other domains such as linguistics or psychology) and methodological caveats (reproducibility, parameters impact, the issue of attribution of results to the representation or the whole system, dataset structure/balance/representativeness).
Theoretical papers might like to consider the following questions:
Proposal papers should introduce a novel method for evaluating representations, accompanied with a proof-of-concept dataset (of which at least a sample should be made available to the reviewers at the submission time). The new method should highlight some previously unnoticed properties of the target representations, or enables a faster/more cost-effective way of measuring some previously known properties. We also invite proposals that can demonstrate a significant improvement to the previous metrics (e.g. update to an imbalanced or noisy dataset that shows that previous claims were misattributed).
Each proposal should explicitly mention:
RepEval 2019 shared task has been cancelled.
Submission is electronic, using the Softconf START conference management at https://www.softconf.com/naacl2019/repeval/
All accepted papers must be presented at the workshop to appear in the proceedings. At least one author of each accepted paper must register for the workshop by the early registration deadline. Previous presentations of the work (e.g. preprints on arXiv.org) should be indicated in a footnote that should be excluded from the review submission, but included in the final version of papers appearing in the NAACL-HLT 2019 proceedings.
