We present a new sentence-aligned monolingual corpus for Simple German - German. It contains multiple document-aligned sources which we have aligned using automatic sentence-alignment methods. We evaluate our alignments based on a manually labelled subset of aligned documents. The quality of our sentence alignments, as measured by the F1-score, surpasses previous work. We publish the dataset under CC BY-SA and the accompanying code under MIT license.enAlignment methodsF1 scoresMultiple documentsSentence alignmentSimple++conference paper
