# Douyin Posts Dataset

A dataset of **1,133,545 unique posts** from Douyin (Chinese TikTok), collected via snowball sampling of related videos.

## Dataset Description

This dataset contains metadata from Douyin short videos, collected by crawling related video recommendations. Starting from seed videos matching specific keywords, the crawler iteratively fetched related videos to build a diverse sample of the platform's content.

### Collection Method

- **Snowball sampling**: Starting from keyword-matched seed videos, related videos were iteratively crawled
- **Deduplication**: All posts are deduplicated by `aweme_id` (unique video identifier)
- **Partitioning**: Data is partitioned by the first 4 digits of `aweme_id` for efficient access

## Dataset Structure

The dataset contains 187 columns. Key fields include:

## Usage

```python
import polars as pl
from huggingface_hub import hf_hub_download
from pathlib import Path

# Download a single partition
file_path = hf_hub_download(
    repo_id="bendavidsteel/douyin",
    filename="data/partition_7500.parquet.zstd",
    repo_type="dataset"
)
df = pl.read_parquet(file_path)

# Or load all partitions
from huggingface_hub import snapshot_download

local_dir = snapshot_download(
    repo_id="bendavidsteel/douyin",
    repo_type="dataset",
    allow_patterns="data/*.parquet.zstd"
)
df = pl.read_parquet(Path(local_dir) / "data" / "*.parquet.zstd")
```

## File Structure

```
data/
├── partition_7035.parquet.zstd
├── partition_7040.parquet.zstd
├── ...
└── partition_7551.parquet.zstd
```

111 partition files, partitioned by the first 4 digits of `aweme_id`.

## Limitations

- Metadata only - does not include actual video/image content
- Point-in-time snapshot - engagement statistics reflect collection time
- Related video sampling may introduce biases toward popular/recommended content
