+## Introduction
+WAON is a Japanese (image, text) pair dataset containing approximately 155M examples, crawled from Common Crawl.
+It is built from snapshots taken in 2025-18, 2025-08, 2024-51, 2024-42, 2024-33, and 2024-26.
+The dataset is high-quality and diverse, constructed through a sophisticated data processing pipeline.
+We apply filtering based on image size and SigLIP scores, and perform deduplication using URLs, captions, and perceptual hashes (pHash).
+
+## How to Use
+
+Clone the repository:
+```bash
+git clone https://gitlab.llm-jp.nii.ac.jp/datasets/waon.git
+cd waon
+```
+
+Load the dataset using the `datasets` library:
+```python
+from datasets import load_dataset
+
+ds = load_dataset("parquet", data_dir="data")
+```
+
+### Format
+
+- `url`: URL of the image
+- `caption`: Caption associated with the image
+- `page_title`: Title of the page containing the image
+- `page_url`: URL of the page
+- `punsafe`: Probability that the image is unsafe
+- `quality`: The quality of the text in the text column
+- `width`: Width (in pixels) of the resized image used for computing pHash
+- `height`: Height (in pixels) of the resized image used for computing pHash
+- `original_width`: Original width of the image
+- `original_height`: Original height of the image
+- `sha256`: SHA-256 hash of the original image file
+- `phash`: Perceptual hash (pHash) computed from the resized image
+
+
+## Dataset Construction Pipeline
+
+We construct WAON dataset through the following steps:
