ReproGen: A Shared Task on Reproducibility of Human Evaluations in NLG: Second Call for Participation Results meeting at INLG’21 in Aberdeen, 20-24 September 2021 https://reprogen.github.io

-------------------------------------------- Second Call for Participation -------------------------------------------- ReproGen Shared Task on Reproducibility of Human Evaluations in NLG Results meeting at INLG’21 in Aberdeen, 20-24 September 2021

-------------------------------------------- Background --------------------------------------------

Across Natural Language Processing (NLP), a growing body of work is exploring the issue of reproducibility in machine learning contexts. However, the reproducibility of the results of human evaluation experiments is currently under-addressed. This is of concern because 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.

With the ReproGen shared task on the reproducibility of human evaluations in NLG we aim (i) to shed light on the extent to which past NLG evaluations have been reproducible, and (ii) to draw conclusions regarding how human 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 --------------------------------------------

Following discussion of the ReproGen proposal at the INLG’20 GenChal session, we are organizing ReproGen with two tracks, one an ‘unshared task’ in which teams attempt to reproduce their own prior human evaluation results (Track B below), the other a shared task in which teams repeat existing human evaluation studies with the aim of reproducing their results (Track A):

A. Main Reproducibility Track: For a shared set of selected human evaluation studies, participants repeat one or more 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 human evaluation results, and report what happened. Unshared task.

-------------------------------------------- Track A Papers -------------------------------------------- Following a call for proposals, we have selected the papers listed below for inclusion in ReproGen Track A. The authors have agreed to human evaluation studies from their papers as identified below to be used for reproduction studies, and have committed to supporting participants in reproduction studies by providing the system outputs to be evaluated and any reusable tools that were used in evaluations, and by being available for questions during the shared task period. Moreover, all authors have completed the ReproGen Human Evaluation Sheet 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]

- Dusek et al. (2018): Findings of the E2E NLG Challenge: (https://www.aclweb.org/anthology/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://www.aclweb.org/anthology/W18-6532.pdf) [only evaluation study in the paper; English; 19 evaluators; 4 quality criteria; reproduction target: primary scores]

- Shaikh & Santhanam (2019): Towards Best Experiment Design for Evaluating Dialogue System Output: (https://www.aclweb.org/anthology/W19-8610.pdf) [3 evaluation studies differing in experimental design; English; x evaluators; 2 quality criteria; reproduction target: correlation scores between 3 studies]

-------------------------------------------- Track A and B instructions --------------------------------------------

Step 1. Fill in the registration form (https://forms.gle/pBPRjPGwoKCY3hsf7), 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 participant's pack 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 Sheet for each reproduction study, by August 15th, 2021.

Step 4. The organizers will carry out light-touch review of the evaluation reports according to the following criteria:

- Evaluation sheet has been completed. - Exact repetition of the 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.

Full details and instructions will be provided in the ReproGen participant’s pack.
