+
+### TL;DR
+This model can be used for **sentiment analysis of German tweets discussing the use of masks** (in the context of the COVID-19 pandemic).
+
+*Check out the paper for details: Will be added soon!*
+
+### Training
+- The classifier is based on [GBERT-base](https://huggingface.co/deepset/gbert-base) and was trained in a two-stage setup. First, it was continuingly pretrained on roughly 340k German tweeets discussing mask.
+Secondly, it was fine-tuned using an annotated dataset of roughly 2k examples.
+- The model is trained to predict tweets into *neutral*, *negative*, or *positive*.
+- Tweets were only preprocessed by replacing urls with 'https' and user mentions with '@user'.
+
+### Performance
+The model achieves a weighted F1-score of 82.36%.
+
+### Inferenence
+If you would like to use the model, you can load it with the `Transformers` librabry:
+
+```
+from transformers import pipeline
+
+model_path = "slvnwhrl/gbert-mask-sentiment"
+gbert_mask = pipeline("sentiment-analysis", model=model_path, tokenizer=model_path)
+
+gbert_mask("insert some text in German") # ready to roll
+```
