ReproGen shared task will be running again this year! You can try to reproduce some of the published results from the list or to reproduce some of your own results (whichever you want).
Reproducing both human as well as automatic evaluations are welcome. Deadline for submitting reports: 6 June 2022 Background 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 Natural Language Generation in particular, where human evaluation is common. More generally, human evaluations provide the benchmarks against which automatic evaluation methods are assessed across NLP, and are moreover widely regarded as the standard form of evaluation in NLG. Following the organisation of 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, we are organising the second ReproGen shared task on reproducibility of evaluations in NLG with a widened scope, now extending to both human and automatic evaluation results. As with the first ReproGen shared task, our aim is (i) to shed light on the extent to which past NLG evaluations have been reproducible, and (ii) to draw conclusions regarding how NLG 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 ReproGen We are once again organising ReproGen with two tracks, one an ‘unshared task’ in which teams attempt to reproduce their own prior automatic or human evaluation results (Track B below), the other a shared task in which teams repeat existing automatic and human evaluation studies with the aim of reproducing their results (Track A): *A. Main Reproducibility Track*: For a shared set of selected evaluation studies (see below), participants repeat one or more of the studies, and attempt to reproduce their results, using published information plus additional information and resources provided by the authors, and making common-sense assumptions where information is still incomplete. *B. RYO Track*: Reproduce Your Own previous automatic or human evaluation results, and report what happened. Unshared task. Track A Papers We have selected the papers listed below for inclusion in ReproGen Track A, four of which were offered in Track A last year. The authors have agreed to evaluation studies from their papers as identified below to be used for reproduction studies. In all cases, the system outputs to be evaluated and any reusable tools that were used in evaluations are available. 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://aclanthology.org/W17-3513.pdf> [1 evaluation study; Dutch; 20 evaluators; 1 quality criterion; reproduction target: primary scores]* *Dušek et al. (2018): Findings of the E2E NLG Challenge <https://aclanthology.org/W18-6539.pdf> [1 evaluation study; English; MTurk; 2 quality criteria; reproduction target: primary scores]* *Qader et al. (2018): Generation of Company descriptions using concept-to-text and text-to-text deep models: dataset collection and systems evaluation <https://aclanthology.org/W18-6532.pdf> [1 evaluation study; English; 19 evaluators; 4 quality criteria; reproduction target: primary scores]* *Santhanam & Shaikh (2019): Towards Best Experiment Design for Evaluating Dialogue System Output <https://aclanthology.org/W19-8610.pdf> [3 evaluation studies differing in experimental design; English; 40 evaluators; 2 quality criteria; reproduction target: correlation scores between 3 studies]* *Nisioi et al. (2017): Exploring Neural Text Simplification Models <https://aclanthology.org/P17-2014.pdf> [one automatic evaluation study; reproduction target: two automatic scores]; [one human evaluation study; 70 sentences; 9 system outputs; 4 quality criteria; reproduction target: primary scores]* Track A and B Instructions Step 1. Fill in the registration form <https://forms.gle/TFK9TWDetBYhwNov5>, indicating which of the above papers, or which of your own papers, you wish to carry out a reproduction study for. Step 2. The ReproGen participants information will be made available to you, plus data, tools and other materials for each of the studies you have selected in the registration form. Step 3. Carry out the reproduction, and submit a report of up to 8 pages plus references and supplementary material including a completed ReproGen Human Evaluation Data Sheet Light (HEDS-Light, a new, simplified version of the original HEDS) for each reproduction study, by 1 June 2022. Step 4. The organisers will carry out light touch review of the evaluation reports according to the following criteria: - HEDS-Light evaluation sheet has been completed. - Exact repetition of study has been attempted and is described in the report. - Report gives full details of the reproduction study, in accordance with the reporting guidelines provided. - All tools and resources used in the study are publicly available. Step 5. Present paper at the results meeting. Reports will be included in the INLG’22 proceedings and results will be presented in the GenChal’22 session at INLG <https://inlgmeeting.github.io/index.html>. Full details and instructions will be provided in the ReproGen participants information.
