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.

Back translation

We have made the back translation from English to German with the help of Fairseq. We used the transformer.wmt19.en-de model for this purpose:

en2de = torch.hub.load(
    "pytorch/fairseq",
    "transformer.wmt19.en-de",
    checkpoint_file="model1.pt:model2.pt:model3.pt:model4.pt",
    tokenizer="moses",
    bpe="fastbpe",
)
