# Dataset Card for OPUS-100-en-ja

### Dataset Summary

This corpus is extracted from **[Helsinki-NLP/opus-100](https://huggingface.co/datasets/Helsinki-NLP/opus-100)**, with Japanese and English pairs.

### How to use

It is used in much the same way as **[Helsinki-NLP/opus-100](https://huggingface.co/datasets/Helsinki-NLP/opus-100)**. The only difference is that you do not have to specify the language.

```
from datasets import load_dataset
dataset = load_dataset("Hoshikuzu/opus-100-en-ja")
```
If data loading times are too long and boring, use Streaming.

```
from datasets import load_dataset
dataset = load_dataset("Hoshikuzu/opus-100-en-ja", streaming=True)
```

## Dataset Structure

### Data Instances

```
{
  'translation': {
    'en': 'Yeah, Vincent Hanna.',
    'ja': '- ラウール - ラウールに ヴィンセント・ハンナだ'
  }
}
```

### Data Fields

Translation dictionaries containing texts from languages 1 and 2.

### Data Splits

The dataset is split into training, development, and test portions.
