# Dataset Card for NTEU Multilingual Evaluation Dataset

## Dataset Description

- **Point of Contact:** langtech@bsc.es


### Dataset Summary

This evaluation dataset for Machine Translation was created by the [NTEU - Neural Translation for the EU](https://pangeanic.com/nteu) project.
The evaluation dataset includes around 1,000 parallel sentences in the 24 official European languages.
The original NTEU dataset has been cleaned and filtered by removing empty lines and near-duplicates, and it has been augmented with Catalan. 
The Catalan version was manually produced by a native Catalan translator from the original English and Spanish versions, and was sponsored by the [AINA project](https://projecteaina.cat/).

### Supported Tasks and Leaderboards

This dataset can be used to evaluate bilingual and multilingual machine translation systems for any combination of the 24 official European languages and Catalan in the legal domain.

### Languages

The languages included in the dataset are the following:

| CODE | LANGUAGE   | SCRIPT      |

## Dataset Structure

### Data Instances

A separate .txt file is provided for each language, with sentences aligned in the same order across all files.
Each file uses the two-letter language code of its language as the file extension.


### Data Fields

[N/A]
    
### Data Splits

The dataset contains a single split: `Test`.

## Dataset Creation

### Curation Rationale

The aim of this dataset is to promote the evaluation of machine translation systems for the official European languages, plus Catalan.

### Source Data

#### Initial Data Collection and Normalization

The data was originally extracted from [EUR-Lex](https://eur-lex.europa.eu/homepage.html), the official online database of European Union law and other public documents of the European Union (EU), published in the 24 official languages of the EU. The Official Journal (OJ) of the European Union is also published on EUR-Lex.

#### Who are the source language producers?

[EUR-Lex](https://eur-lex.europa.eu/homepage.html)

### Annotations

#### Annotation process

The dataset does not contain any annotations.

#### Who are the annotators?

[N/A]

### Personal and Sensitive Information

No specific anonymisation process has been applied, personal and sensitive information may be present in the data. 
This needs to be considered when using the data for training models.

## Considerations for Using the Data

### Social Impact of Dataset

By providing this resource, we intend to promote the evaluation of machine translation systems including all the official European Languages and Catalan, thereby improving the accessibility and visibility of the Catalan language in Europe.

### Discussion of Biases

No specific bias mitigation strategies were applied to this dataset. 
Inherent biases may exist within the data.

### Other Known Limitations

The dataset contains data of a legal/administrative domain. Applications of this dataset in other domains would be of limited use.
