+# Model card for PM-AI/paraphrase-distilroberta-base-v2_de-en
+For internal purposes and for testing, we have made a monolingual paraphrasing model from Sentence Transformers usable for _German + English_ via [Knowledge Distillation](https://arxiv.org/abs/2004.09813).
+The decision was made in favor of [sentence-transformers/paraphrase-distilroberta-base-v2](https://huggingface.co/sentence-transformers/paraphrase-distilroberta-base-v2) because this model has not public available multilingual version (to our knowledge).
+In addition, it has a significantly more training samples compared to its predecessor: 83.3 million samples were used instead of 24.6 million samples.
+
+## Training
+1) Download of datasets
+2) Execution of knowledge distillation
+
+### Training Data
+Datasets used based on [offical source](https://www.sbert.net/examples/training/paraphrases/README.html):
+  - _AllNLI_
+  - _sentence-compression_
+  - _SimpleWiki_
+  - _altlex_
+  - _msmarco-triplets_
+  - _quora_duplicates_
+  - _coco_captions_
+  - _flickr30k_captions_
+  - _yahoo_answers_title_question_
+  - _S2ORC_citation_pairs_
+  - _stackexchange_duplicate_questions_
+  - _wiki-atomic-edits_
+
+### Training Execution
+
+First we downloaded some german-english parallel datasets via [get_parallel_data_*.py](https://github.com/UKPLab/sentence-transformers/tree/b86eec31cf0a102ad786ba1ff31bfeb4998d3ca5/examples/training/multilingual).
+
+These datasets are: _Tatoeba_, _WikiMatrix_, _TED2020_, _OpenSubtitles_, _Europarl_, _News-Commentary_
+
+Then we started knowledge distillation with [make_multilingual_sys.py](https://github.com/UKPLab/sentence-transformers/blob/b86eec31cf0a102ad786ba1ff31bfeb4998d3ca5/examples/training/multilingual/make_multilingual_sys.py)
