# Dataset Card for CCMatrix-en-ja

### Dataset Summary

This corpus is extracted from **[yhavinga/ccmatrix](https://huggingface.co/datasets/yhavinga/ccmatrix)**, with Japanese and English pairs.

### How to use

It is used in much the same way as **[yhavinga/ccmatrix](https://huggingface.co/datasets/yhavinga/ccmatrix)**. The only difference is that you do not have to specify the language.

```
from datasets import load_dataset
dataset = load_dataset("yhavinga/ccmatrix")
```
If data loading times are too long and boring, use Streaming.

```
from datasets import load_dataset
dataset = load_dataset("yhavinga/ccmatrix", streaming=True)
```

## Dataset Structure

### Data Instances
For example:

```json
{
        'id': 0,
        'score': 1.2499920129776,
        'translation': {
            'en': 'Such is God’s forgiveness.',
            'ja': 'それは神の赦しの故だ。'
        }
  }
```

### Data Fields
Each example contains an integer id starting with 0, a score, and a translation dictionary with the language 1 and
language 2 texts.

### Data Splits
Only a `train` split is provided.
