# SciPar Parallel Documents

# Dataset Description

This dataset contains parallel documents (i.e., titles & abstracts) extracted from academic theses, dissertations, and other scientific texts.

In the original [paper](https://aclanthology.org/2022.lrec-1.284.pdf), we've extracted 9.17M sentence pairs in 31 language pairs from 86 repositories.

This version has been created through further processing and filtering to extract parallel **documents** instead of parallel **sentences**. 

To do this, we kept only the parallel titles and abstracts of academic records with high (mean) alignment scores by also using other filters (e.g., word ratio, non-empty abstracts, etc.).

Please note that this dataset will keep getting updated to include *more language pairs*, per the original paper.
