# Dataset Card for Ancient Greek Interlinear Translations Dataset

This dataset provides word-level aligned interlinear translations of the New Testament from Ancient Greek to English and Polish with morphological tags sourced from Oblubienica (https://biblia.oblubienica.pl) and BibleHub (https://biblehub.com/interlinear).

See https://github.com/mrapacz/loreslm-interlinear-translation for more details.

## Dataset Details

### Dataset Description

The dataset contains interlinear translations where each Greek word is paired with its corresponding Polish and English translations, along with morphological tags from two different annotation systems. We applied a set of heuristics to align the corpora at the word level. The alignment process achieved over 99% word matching accuracy, with unmatched words being excluded. Subsequently, we trimmed all verses so that the least memory-efficient models tested in our research could encode them within the chosen limit of 512 tokens.
