ReproNLP 2023: First Call for ParticipationBackground Across Natural Language Processing (NLP), a growing body of work is exploring the issue of reproducibility in machine learning contexts. The field is currently far from having a generally agreed tool box of methods for defining and assessing reproducibility. Reproducibility of results of human evaluation experiments is particularly under-addressed which is of concern for areas of NLP where human evaluation is common including e.g. MT, text generation and summarisation. More generally, human evaluations provide the benchmarks against which automatic evaluation methods are assessed across NLP.
We previously organised the First ReproGen Shared Task <https://reprogen.github.io/2021/> on reproducibility of human evaluations in NLG as part of Generation Challenges (GenChal) at INLG’21, and the Second ReproGen Shared Task <https://reprogen.github.io/> at INLG’22, where we extended the scope to encompass automatic evaluation methods as well as human. This year we are expanding the scope of the shared task series to encompass all NLP tasks, renaming it the ReproNLP Shared Task on Reproducibility of Evaluations in NLP. This year we are focussing on human evaluations, and the results session will be held at the 3rd Workshop on Human Evaluation of NLP Systems (HumEval 2023) <https://humeval.github.io/> . As with the ReproGen shared tasks, our overall aim is (i) to shed light on the extent to which past NLP evaluations have been reproducible, and (ii) to draw conclusions regarding how NLP evaluations can be designed and reported to increase reproducibility. If the task is run over several years, we hope to be able to document an overall increase in levels of reproducibility over time. About ReproNLP ReproNLP has three tracks, one an ‘unshared task’ in which teams attempt to reproduce their own prior evaluation results (Track B below), the others standard shared tasks in which teams repeat existing evaluation studies with the aim of reproducing their results (Tracks A and C): A. Legacy Reproducibility Track: For a shared set of selected evaluation studies from ReproGen 2022 (see below), participants repeat one or more of the studies, and attempt to reproduce their results. As in ReproGen, participants will be given additional information and resources (beyond what is in the published papers) about experimental details by the ReproNLP organisers. B. RYO Track: Reproduce Your Own previous evaluation results, and report what happened. Unshared task. C. ReproHum Track: For a shared set of selected evaluation studies from the ReproHum Project <https://reprohum.github.io/>, participants repeat one or more of the studies, and attempt to reproduce their results, using information provided by the ReproNLP organisers only, and following a common reproduction approach. Track A Papers We have selected the papers listed below for inclusion in ReproNLP Track A (these are the same papers as in Track A in ReproGen 2022). The authors have agreed to evaluation studies from their papers as identified below being used for Track A, and have provided the system outputs to be evaluated and any reusable tools that were used in the original evaluations. We also have available completed ReproGen Human Evaluation Sheets which we will use as the standard for establishing similarity between different human evaluation studies. The papers and studies, with many thanks to the authors for supporting ReproGen, are: van der Lee et al. (2017): PASS: A Dutch data-to-text system for soccer, targeted towards specific audiences: https://www.aclweb.org/anthology/W17-3513.pdf [1 evaluation study; Dutch; 20 evaluators; 1 quality criterion; reproduction target: primary scores] Dušek et al.

The authors have agreed to us using them in ReproNLP and have provided very detailed information about the experiments. In some cases we have introduced standardisations to the experimental design as noted in the detailed instructions to participants which will be shared upon registration.
