**This dataset card is still a draft version. The dataset has not been uploaded yet.**

This is a record of German language paraphrases. These are text pairs that have the same meaning but are expressed in different words.
The source of the paraphrases are different parallel German / English text corpora.
The English texts were machine translated back into German. This is how the paraphrases were obtained.
