| # MIRACL Triplets in 51 Languages |
|
|
| ## Dataset Summary |
|
|
| MIRACL Triplets in 51 Languages is a multilingual retrieval and reranking dataset for training dense retrieval, sentence embedding, reranker, and cross-lingual search models. It contains `(query, positive, negative)` triplets derived from the English training split of [`miracl/miracl`](https://huggingface.co/datasets/miracl/miracl). |
|
|
| The dataset provides **51 language subsets**: the original English data and translations into 50 languages. Each subset contains **2,863 aligned training examples**. Rows with the same `id` represent translations of the same source triplet. The aligned `(query, positive, negative)` structure supports multilingual retrieval, multilingual reranking, contrastive learning, and hard-negative training. |
|
|
| - Format: Parquet |
| - Subsets: 51 language codes, including `en`, `ko`, `ja`, `zh`, `de`, and `fr` |
| - Split: `train` |
| - Rows per subset: 2,863 |
| - Total rows across subsets: 146,013 |
|
|
| ## Data Structure |
|
|
| | Column | Type | Description | |
| |---|---|---| |
| | `id` | `int64` | Alignment identifier shared across language subsets | |
| | `query` | `string` | Search query | |
| | `positive` | `string` | Passage relevant to the query | |
| | `negative` | `string` | Passage not relevant to the query | |
|
|
| ## Data Instances |
|
|
| Example from the English subset: |
|
|
| ```json |
| { |
| "id": 232, |
| "query": "What is Nigers anthem?", |
| "positive": "La Nigérienne\n\"La Nigérienne\" is the national anthem of Niger. The lyrics are by Maurice Albert Thiriet. Robert Jacquet and Nicolas Abel François Frionnet wrote the music. It was adopted as Niger's anthem in 1961.", |
| "negative": "Nigeria, We Hail Thee\nThe second national anthem, \"Arise, O Compatriots,\" replaced \"Nigeria, We Hail Thee\" in 1978." |
| } |
| ``` |
|
|
| ## How to Use |
|
|
| ```python |
| from datasets import load_dataset |
| |
| # Load one language subset. Replace "ko" with any supported language code. |
| dataset = load_dataset("nlpai-lab/miracl-multilingual-triplets", "ko", split="train") |
| |
| print(dataset.features) |
| print(dataset[0]) |
| ``` |
|
|
| The default subset is English (`en`). |
|
|
| ## Source and Translation |
|
|
| - Source dataset: [`miracl/miracl`](https://huggingface.co/datasets/miracl/miracl) |
| - Source configuration: `en` |
| - Source split: `train` |
| - Translation model: [`google/translategemma-27b-it`](https://huggingface.co/google/translategemma-27b-it) |
|
|
| The model's original translation prompt template was used without modification or additional instructions. The `query`, `positive`, and `negative` fields were translated independently while preserving their triplet relationship and cross-language `id` alignment. |
