+The original dataset: https://www.kaggle.com/datasets/nelgiriyewithana/emotions
+
+The derived dataset was machine translated from English into Russian using the free Google Translate API (with [deep-translator](https://pypi.org/project/deep-translator/)). The translation script:
+
+```python
+import pandas as pd
+from deep_translator import GoogleTranslator
+from deep_translator.exceptions import TranslationNotFound
+
+# Load dataset and drop the ID column
+df = pd.read_csv("path_to_your_downloaded_file/text.csv").iloc[:, 1:]
+
+translator = GoogleTranslator(source="en", target="ru")
+
+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...")
+
+    # Replace None with original text if translation is not applicable
+    translated = [
+        t if t is not None else orig
+        for t, orig in zip(translated, texts)
+    ]
+
+    # Print replacements
+    for t, orig in zip(translated, texts):
+        if t == orig:
+            print(f"Replaced {orig} with {t}")
+
+    samples["ru_text"] = translated
+    return samples
+
+# Apply batch translation
+batch_size = 500
+translated_dataset = df.groupby(df.index // batch_size, group_keys=False).apply(translate_samples)
+```
+
+Column `labels` contain the following classes:
+```yaml
+0: sadness
+1: joy
+2: love
+3: anger
+4: fear
+5: surprise
+```
+
+Column `labels_ekman` contains the Ekman emotion classes:
+```yaml
+0: anger
+1: disgust - omitted in this dataset
+2: fear
+3: joy
+4: sadness
+5: surprise
+6: neutral - omitted in this dataset
+```
+which were mapped from the original classes as follows:
+```yaml
+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)
+```
