# Multilingual Text Classification Dataset

This dataset is designed for **multilingual text classification** tasks.
It includes labeled text samples across **8 languages**, making it ideal for training and evaluating models on **cross-lingual transfer**, **language identification**, and **multilingual understanding**.

| Validation | 2,665      | 378,709       |
| Test       | 5,331      | 757,560       |
| **Total**  | **26,653** | **3,787,517** |

**Total Download Size:** 2.6 MB
**Total Dataset Size:** 3.8 MB
**Task Type:** Text Classification


## Data Fields

| Field   | Type     | Description                                        |
| ------- | -------- | -------------------------------------------------- |
| `text`  | `string` | The input text sample.                             |
| `lang`  | `string` | The ISO 639-3 language code of the text.           |
| `label` | `int64`  | The integer label representing the language class. |


## Language Labels

## Intended Uses

* Multilingual language classification
* Cross-lingual and zero-shot evaluation
* Benchmarking multilingual embeddings (e.g., mBERT, XLM-R, LaBSE)
* Studying language similarity and confusion patterns


## Usage Example

You can easily load the dataset using the Hugging Face `datasets` library:

```python
from datasets import load_dataset

dataset = load_dataset("8Opt/multilingual-classification-0001")

example = dataset["train"][0]
print(example)
```

Output:

```python
{
  "text": "Das ist ein Beispielsatz.",
  "lang": "deu",
  "label": 0
}
```

Label mapping:

```python
label2idx = {
  'deu': 0,
  'zho': 1,
  'amh': 2,
  'hin': 3,
  'arb': 4,
  'hau': 5,
  'tur': 6,
  'urd': 7,
  'spa': 8,
  'fas': 9,
  'eng': 10,
  'nep': 11
}

```


## Configurations
