# Ancient Greek BERT finetuned for tagging and parsing PROIEL (UD)

This is a finetuned checkpoint of [Ancient Greek BERT](https://huggingface.co/pranaydeeps/Ancient-Greek-BERT) by Singh, Rutten and Lefever (2021), which has been trained on the [UD version of PROIEL per 9 May 2023](https://github.com/UniversalDependencies/UD_Ancient_Greek-PROIEL/tree/a2cc6342ca152c257d7e531f98eaba097553c3e5).

The code for training and using the model can be found on [GitHub](https://github.com/clemeth/tagparse). The config file used is here: [`config.py`](config.py).

If you use this model for something academic, feel free to cite the master's thesis that it sprung out of:
