# Dataset Card for XNLIeu

<!-- Provide a quick summary of the dataset. -->

XNLIeu is an extension of [XNLI](https://huggingface.co/datasets/xnli) translated from English to **Basque**. It has been designed as a cross-lingual dataset for the Natural Language Inference task, a text-classification task that consists on classifying pairs of sentences, a premise and a hypothesis, according to their semantic relation out of three possible labels: entailment, contradiction and neutral.

## Dataset Details

### Dataset Description

<!-- Provide a longer summary of what this dataset is. -->
XNLI is a popular Natural Language Inference (NLI) benchmark widely used to evaluate cross-lingual Natural Language Understanding (NLU) capabilities across languages. 
We expand XNLI to include Basque, a low-resource language that can greatly benefit from transfer-learning approaches. 
The new dataset, dubbed XNLIeu, has been developed by first machine-translating the English XNLI corpus into Basque, followed by a manual post-edition step.

- **Language(s) (NLP):** Basque (eu)
- **License:** XNLIeu is derived from XNLI and distributed under its same license. 

### Dataset Sources

<!-- Provide the basic links for the dataset. -->

- **Repository:** [Link to the GitHub Repository](https://github.com/hitz-zentroa/xnli-eu/)
- **Paper:** [Link to the Paper](https://aclanthology.org/2024.naacl-long.234/)

## Uses

XNLieu is meant as an cross-lingual evaluation dataset. It can be used in combination with the train sets of [XNLI](https://huggingface.co/datasets/xnli) for a cross-lingual zero-shot setting, and we provide a machine-translated train set in both "eu" and "eu_mt" splits to implement a translate-train setting.

## Dataset Structure
The dataset has three subsets:
- **eu**: XNLIeu, machine-translated and post-edited from English to Basque.
- **eu_MT**: XNLIeu<sub>MT</sub>, a machine-translated version prior post-edition.
- **eu_native**: An original, non-translated test set.


### Splits

|    name     |train |validation|test|
|-------------|-----:|---------:|---:|
|eu           |392702|      2490|5010|
|eu_mt        |392702|      2490|5010|
|eu_native    |-     |      -   |621 |


### Dataset Fields

All splits have the same fields: *premise*, *hypothesis* and *label*.
- **premise**: a string variable.
- **hypothesis**: a string variable.
- **label**: a classification label, with possible values including entailment (0), neutral (1), contradiction (2).

### Dataset Instances

An example from the "eu" split:

```
{
    "premise": "Dena idazten saiatu nintzen"
    "hypothesis": "Nire helburua gauzak idaztea zen.",
    "label": 0,
}
```

The new dataset, dubbed XNLIeu, has been developed by first machine-translating the English XNLI corpus into Basque, followed by a manual post-edition step. We have conducted a series of experiments using mono- and multilingual LLMs to assess a) the effect of professional post-edition on the MT system; b) the best cross-lingual strategy for NLI in Basque; and c) whether the choice of the best cross-lingual strategy is influenced by the fact that the dataset is built by translation. The results show that post-edition is necessary and that the translate-train cross-lingual strategy obtains better results overall, although the gain is lower when tested in a dataset that has been built natively from scratch. Our code and datasets are publicly available under open licenses.",
