+# PhilBerta
+
+The paper [Exploring Language Models for Classical Philology](https://todo.com) is the first effort to systematically provide state-of-the-art language models for Classical Philology. PhilBerta is a RoBerta-base sized, multilingual, encoder-only variant.  
+
+This model was trained using data from the [Open Greek & Latin Project](https://opengreekandlatin.org/), the CLARIN corpus [Greek Medieval Texts](https://inventory.clarin.gr/corpus/890), the [Patrologia Graeca](https://patristica.net/graeca/), the [Corpus Corporum](https://mlat.uzh.ch/), and [Project Gutenberg](https://www.gutenberg.org/).
+
+Further information can be found in our paper or in our [GitHub repository](https://github.com/Heidelberg-NLP/ancient-language-models).
+
+## Usage
+```python
+from transformers import AutoTokenizer, AutoModelForMaskedLM
+
+tokenizer = AutoTokenizer.from_pretrained('bowphs/PhilBerta')
+model = AutoModelForMaskedLM.from_pretrained('bowphs/PhilBerta')
+```
+Please check out the awesome Hugging Face tutorials on how to fine-tune our models.
+
+## Evaluation Results
+When fine-tuned on data from [Universal Dependencies 2.10](https://universaldependencies.org/), PhilBerta achieves the following results on the Ancient Greek Perseus dataset:
+
+| Task | XPoS | UPoS  | UAS | LAS |
+|:--:|:--:|:--:|:--:|:--:|
+|      |95.60|90.41|86.99|82.69|
+
+When fine-tuned on PoS data from [EvaLatin 2022](https://universaldependencies.org/), it achieves the following results:
+
+| Task | Classical | Cross-genre  | Cross-time | 
+|:--:|:--:|:--:|:--:|
+|      |98.23|96.59|93.25|
