As the #GEM team already mentioned, we have endorsed the #data2text and #summarization shared tasks taking place this year: https://gem-benchmark.com/shared_task

For data-to-text, there are two different datasets and you can choose to work with factual, counterfactual, or fictional versions of the datasets.

For summarization, you can work on Swahili, cross-lingual summarizaion, or summarizing English book chapters.

Interesting challenges with a deadline of 5 April with human evaluations starting on the 6th
