# Twitter Emotions dataset in Lithuanian

The original dataset: [Emotions](https://doi.org/10.34740/kaggle/dsv/7563141)

The derived dataset was machine translated from English into Lithuanian using the free Google Translate API (with [deep-translator](https://pypi.org/project/deep-translator/)). It also contains an additional `labels_ekman` column that maps the original emotion classes to the [Paul Ekman's classification](https://en.wikipedia.org/wiki/Emotion_classification).

The translation script:

```python
import pandas as pd
from deep_translator import GoogleTranslator
from deep_translator.exceptions import TranslationNotFound

# Loads the dataset and drops the ID column
df = pd.read_csv("text.csv").iloc[:, 1:]

translator = GoogleTranslator(source="en", target="lt")

def translate_samples(samples):
    texts = samples["text"].tolist()

    while True:
        try:
            translated = translator.translate_batch(texts)
            break
        except TranslationNotFound:
            print(f"Translation failed for '{texts}', retrying...")

    # Replaces None values with the original text if translation was not successful
    translated = [
        t if t is not None else orig
        for t, orig in zip(translated, texts)
    ]

    # Prints replacements
    for t, orig in zip(translated, texts):
        if t == orig:
            print(f"Replaced {orig} with {t}")

    samples["lt_text"] = translated
    return samples

# Apply batch translation
batch_size = 500
translated_dataset = df.groupby(df.index // batch_size, group_keys=False).apply(translate_samples)
```

The column `labels` contains the emotion classes of the original dataset:
```yaml
0: sadness
1: joy
2: love - not distinguished in the Ekman's classification
3: anger
4: fear
5: surprise
```

The column `labels_ekman` contains the corresponding Ekman's emotion classes:
```yaml
0: anger
1: disgust - omitted, since not used in the original dataset
2: fear
3: joy
4: sadness
5: surprise
```

The mapping from the original to the Ekman's classification is made as follows:

| Original | Ekman |
|---|---|
| sadness (0) | sadness (4) |
| joy (1) | joy (3) |
| love (2) | joy (3) |
| anger (3) | anger (0) |
| fear (4) | fear (2) |
| surprise (5) | surprise (5) |
