# Turkish Clean Text Corpus

## Dataset Description

This dataset is a highly cleaned, deduplicated, and normalized corpus of Turkish text. It features a diverse collection of informative, encyclopedic, and journalistic content. 

The dataset is primarily designed for **Continued Pre-Training (CPT)** of Large Language Models (LLMs) to enhance their Turkish language capabilities and domain knowledge. It is also an excellent foundational corpus for generating synthetic Instruction/ChatML datasets or building large-scale **Retrieval-Augmented Generation (RAG)** systems.

- **Language:** Turkish (`tr`)
- **Total Rows:** 540,735
- **Average Word Count per Row:** ~213 words
- **Format:** Hugging Face Dataset (Arrow/Parquet)

## Usage

You can easily download and use this dataset in your Python projects using the Hugging Face `datasets` library. 

First, ensure you have the required library installed:

```bash
pip install datasets
```

```python
from datasets import load_dataset

# Load the dataset
dataset = load_dataset("mehmettozlu/clean-tr-dataset", split="train")

# Check the total number of rows
print(f"Total rows: {len(dataset)}")

# Print the first text example
print(dataset[0]["text"])

# Optional: Convert to Pandas DataFrame for easy manipulation
df = dataset.to_pandas()
print(df.head())
```

## Dataset Structure

The dataset contains a single feature:

- `text` (string): The cleaned, deduplicated Turkish text.

### Example

```json
{
  "text": "Ophrys apifera, Salepgiller ailesine bağlı, arı salebi olarak bilinen, bir orkide türüdür.\n\nBilimsel Tanımı\nOphrys apifera 20 ila 70 cm boylanabilen bir türdür. Gövde yapraksıdır.
