DBBErt

DBBErt: A BERT-based Language Model for Byzantine Greek

---

📖 Model Description

DBBErt is a transformer-based language model fine-tuned for Byzantine Greek, trained on data from the Database of Byzantine Book Epigrams (DBBE).
It supports tasks such as:

• Part-of-speech tagging
• Morphological analysis
• Lemmatization

The model is designed to process both Greek texts from critical editions and unedited medieval Greek texts, which are characterised by:

• Non-standard orthography
• Dialectal and diachronic variation
• Manuscript-based transcription conventions

🛠️ How to Use

Example with 🤗 Transformers:

from transformers import AutoTokenizer, AutoModelForTokenClassification

tokenizer = AutoTokenizer.from_pretrained("coswaele/DBBErt")
model = AutoModelForTokenClassification.from_pretrained("coswaele/DBBErt")

text = "ἐν τοῖς βιβλίοις"
tokens = tokenizer(text, return_tensors="pt")
outputs = model(**tokens)
