Automatic Translation Alignment of Ancient Greek Texts

GRC-ALIGNMENT model is an XLM-RoBERTa-based model, fine-tuned for automatic multilingual text alignment at the word level. The model is trained on 12 million monolingual ancient Greek tokens with Masked Language Model (MLM) training objective. Further, the model is fine-tuned on 45k parallel sentences, mainly in ancient Greek-English, Greek-Latin, and Greek-Georgian.

Multilingual Training Dataset

Languages	Sentences	Source
GRC-ENG	32.500	Perseus Digital Library (Iliad, Odyssey, Xenophon, New Testament)
GRC-LAT	8.200	Digital Fragmenta Historicorum Graecorum project
GRC-KAT GRC-ENG GRC-LAT GRC-ITA GRC-POR	4.000	UGARIT Translation Alignment Editor

Model Performance

Languages	Alignment Error Rate
GRC-ENG	19.73% (IterMax)
GRC-POR	23.91% (IterMax)
GRC-LAT	10.60% (ArgMax)

The gold standard datasets are available on Github.
