# Tigre Parallel Multilingual Dataset (Tigre-Data 1.0)

## Overview

This repository introduces the **Parallel Multilingual Text** component of the Tigre language resource collection. Tigre is an under-resourced South Semitic language within the Afro-Asiatic family.

The goal of **Tigre-Data 1.0** is to accelerate research in low-resource NLP and morphologically rich language modeling. This dataset provides a clean, high-quality parallel corpus essential for developing and evaluating **Machine Translation (MT)** systems for Tigre.

### Data Source & Licensing

The parallel sentences in this dataset originate from Tatoeba.org, a community-driven multilingual corpus released under the CC-BY 2.0 license. All Tigre translations were contributed by native-speaking members of the Tigre diaspora, reflecting years of collective volunteer effort to expand the language’s digital presence. This contribution is significant, as, by the end of 2025, the Tigre language on Tatoeba.org is supported by 77 registered translators working across more than ten other languages, resulting in a larger sentence pool than 93% of the 429 hosted languages.

## How to Download & Load the Dataset

```python
from datasets import load_dataset
import pandas as pd

dataset = load_dataset(
    "BeitTigreAI/tigre-data-parallel-multilingual",
    data_files={
        "train": "train.parquet",
