Automatically created datasets
1) The first dataset is created by Bram Vanroy for Dutch text simplification tasks using text-to-text transfer transformers.It comprises Dutch source sentences along with their corresponding simplified sentences, generated with ChatGPT.
- Training = 1013 sentences (262 KB)
- Validation = 126 sentences (32.6 KB)
- Test = 128 sentences (33 KB)
2) The second dataset is created by UWV Nederland as part of the "Leesplank" project to ensure ethical and legal soundness. It comprises 2.87 million paragraphs and its simplified text as corresponding result. The paragraphs are based on the Dutch Wikipedia extract from Gigacorpus.
