# /pol/ 4chan Augmented Dataset

**134.5M posts** from 3.4M threads on 4chan's /pol/ board (June 2016 - November 2019), augmented with Perspective API toxicity scores and named entity recognition.

## Dataset Description

This dataset contains posts from 4chan's Politically Incorrect (/pol/) board, collected between June 2016 and November 2019. Each post has been augmented with:

- **Perspective API toxicity scores** (7 dimensions): toxicity, severe_toxicity, inflammatory, profanity, insult, obscene, spam
- **Named Entity Recognition**: extracted entities stored as JSON arrays

### Format

270 parquet shards with zstd compression (~70MB each). The dataset is directly loadable with HuggingFace `datasets`:

```python
from datasets import load_dataset
ds = load_dataset("ylelauta/pol-4chan-augmented")
