===NFI SimpleWiki dataset===

Translated dataset created by Netherlands Forensic Institute using Meta's [https://ai.meta.com/research/no-language-left-behind/ No Language Left Behind model]. It comprises 167,000 aligned sentence pairs and serves as a Dutch translation of the SimpleWiki [https://cs.pomona.edu/~dkauchak/simplification/ dataset].

==Comparable Corpus Wablieft De Standaard==

Corpus created by Nick Vanackere. It contains a comparable corpus of 12,687 Wablieft articles between 2012-2017 from 206,466 De Standaard articles from 2013-2017. To ensure comparability, only articles from 08/01/2013 till 16/11/2017 were considered, resulting in 8,744 Wablieft articles and 202,284 De Standaard articles. The difference in the number of articles is due to the publication frequency, with Wablieft being weekly and De Standaard daily.

==Synthetic datasets==

===SONAR WRPEI Simplification Dataset===

The Synthetic Simplification Dataset was compiled within the Duidelijke Taal project and is based on the WR-P-E-I component (websites) of the SoNaR corpus. The dataset consists of three parts: 6,986 sentences from the SoNaR corpus, a synthetic simplification of the SoNaR sentences created by GPT-4 and sentence pairs consisting of one SoNaR sentence and its simplified version each.

====Human evaluation of automated text simplification: crowdsourcing results====

The language material ‘Human evaluation of automated text simplification: crowdsourcing results’ was compiled as part of the Duidelijke Taal project. The dataset consists of sentences from the SoNaR corpus, a version simplified by GPT-4 and the human evaluations of those simplifications with respect to simplicity, accuracy and fluency. The sentence pairs are a subset of the SONAR WRPEI Simplification Dataset

===UWV Leesplank NL wikipedia===

The set contains 2,391,206 pragraphs of prompt/result combinations, where the prompt is a paragraph from Dutch Wikipedia and the result is a simplified text, which could include more than one paragraph. This dataset was created by UWV, as a part of project "Leesplank", an effort to generate datasets that are ethically and legally sound.

A more extended version of this dataset was made by Michiel Buisman and Bram Vanroy. This datasets contains a first, small set of variations of Wikipedia paragraphs in different styles (jargon, official, archaïc language, technical, academic, and poetic).

===ChatGPT generated dataset by Van de Velde===

Created in light of a master thesis by Charlotte Van de Velde. The dataset contains Dutch source sentences and aligned simplified sentences, generated with ChatGPT. All splits combined, the dataset consists of 1267 entries.

# Training = 1013 sentences (262 KB)
# Validation = 126 sentences (32.6 KB)
# Test = 128 sentences (33 KB)

==Manually simplified==

===Dutch municipal data===

The Dutch municipal corpus is a parallel monolingual corpus for the evaluation of sentence-level simplification in the Dutch municipal domain. The corpus was created by Amsterdam Intelligence. It contains 1,311 translated parallel sentence pairs that were automatically aligned. The sentence pairs originate from 50 documents from the Communications Department of the City of Amsterdam that were manually simplified to evaluate simplification for Dutch.
