# Dataset Card for LuxAlign
## Loading the Dataset
The dataset is currently at **version v3**, which can be loaded as:
```python
from datasets import load_dataset
ds = load_dataset("fredxlpy/LuxAlign", name="lb-en") # or "lb-fr"
```
If you want to reproduce the results from the paper (`v1`) or use any previous version, you can specify the version folder:
```python
# Load version v1 (as used in the paper)
ds_v1 = load_dataset("fredxlpy/LuxAlign", data_dir="data/v1", data_files={"train": "lb_en.json"})
```
## Dataset Summary
LuxAlign is a parallel dataset featuring Luxembourgish-English and Luxembourgish-French sentence pairs, introduced in [*LuxEmbedder: A Cross-Lingual Approach to Enhanced Luxembourgish Sentence Embeddings* (Philippy et al., 2025)](https://aclanthology.org/2025.coling-main.753/). Designed to align the Luxembourgish embedding space with those of other languages, it enables improved cross-lingual sentence representations for Luxemborgish. This dataset was used to train the Luxembourgish sentence embedding model [**LuxEmbedder**](https://huggingface.co/fredxlpy/LuxEmbedder). The data originates from news articles published by the Luxembourgish news platform [RTL.lu](https://www.rtl.lu).
The sentence pairs in this dataset are not always exact translations but instead reflect high semantic similarity; hence, this dataset may not be suitable for training a machine translation model without caution.
