The 9th Conference on Machine Translation (WMT24), collocated with EMNLP 2024, will be featuring this year the Shared Task on evaluation of Automatic Metrics. We are looking for both reference-based metrics and reference-free metrics to evaluate the quality of MT systems. We’ll be using expert-based MQM annotations on English-German, English-Spanish and Japanese⇾Chinese as the primary gold standard for evaluating metrics. Details are at http://www2.statmt.org/wmt24/metrics-task.html.

We’ll be continuing the challenge sets subtask [1] this year: we invite anyone to submit a new test suite and/or an analysis paper on metric behaviour for specific perturbations/phenomena (you’re welcome to resubmit last year’s challenge set!)

New this year:
- New language pairs: English-Spanish and Japanese⇾Chinese
- Additional 13 typologically diverse African languages in a challenge set
- We will be using the Codabench platform to improve the metric submission experience

Important dates:
- Challenge sets submission deadline: 11th July
- Metrics inputs ready to download: 23rd July
- Metric submission deadline: 30th July
- Metric scores for challenge sets distributed: 6th August
- Paper submission deadline to WMT: 20th August

Please register your metric submissions here [2] and challenge set submissions [3] here so we can keep track of participants.

Looking forward to your submissions,
WMT24 Metrics team
