# Dataset Statistics
UV scripts for analyzing HuggingFace datasets using streaming mode.
## Scripts
### `finepdfs-stats.py` - Temporal Educational Quality Analysis
Analyze educational quality trends across CommonCrawl dumps using Polars streaming. Answers: **"Is the web getting more educational over time?"**
**Features:**
- Polars streaming (no download of 300GB+ dataset)
- Temporal analysis across 106 CommonCrawl dumps (2013-2025)
- ASCII chart visualizations
- Uploads results to HF Hub with auto-generated dataset card
- Supports single language or all 70+ languages
**Quick Examples:**
```bash
# Quick test (10K samples)
uv run https://huggingface.co/datasets/uv-scripts/dataset-stats/raw/main/finepdfs-stats.py \
--limit 10000 --show-plan
# Analyze English PDFs
uv run https://huggingface.co/datasets/uv-scripts/dataset-stats/raw/main/finepdfs-stats.py \
--output-repo username/my-stats
# Analyze ALL 70+ languages
uv run https://huggingface.co/datasets/uv-scripts/dataset-stats/raw/main/finepdfs-stats.py \
--all-languages --output-repo username/my-stats
```
**Run on HF Jobs (recommended for full dataset):**
```bash
hf jobs uv run \
-s HF_TOKEN \
-e HF_XET_HIGH_PERFORMANCE=1 \
https://huggingface.co/datasets/uv-scripts/dataset-stats/raw/main/finepdfs-stats.py \
-- --all-languages --output-repo username/finepdfs-temporal-stats
```
**Example output:** [davanstrien/finepdfs-temporal-stats-all](https://huggingface.co/datasets/davanstrien/finepdfs-temporal-stats-all)
**Performance:**
- 50M docs in ~14 minutes (~60K docs/sec)
- Single scan using [Polars HF Hub integration](https://huggingface.co/docs/hub/datasets-polars)
- Works on HF Jobs CPU instances
## Related Scripts
Check out other scripts in the [uv-scripts organization](https://huggingface.co/uv-scripts):
- **dataset-creation**: Create datasets from PDFs and other formats
- **vllm**: GPU-accelerated classification and inference
- **ocr**: Document OCR using vision-language models
## Why UV Scripts?
UV scripts are self-contained Python scripts that:
- Run with a single `uv run` command (no setup required)
- Include all dependencies in PEP 723 inline metadata
- Work seamlessly on both local machines and HF Jobs
