Common Crawl
Common Crawl provides petabytes of open web crawl data, consistently collected over a decade. This vast, free resource is fundamental for training and developing Large Language Models (LLMs), enabling researchers to build robust AI systems without the cost of data collection.
4 Steps
- 1
Understand Common Crawl's Value: Recognize Common Crawl as a critical, open-source dataset for AI, particularly for training and fine-tuning Large Language Models. Its scale and accessibility democratize LLM development.
- 2
Explore Available Crawl Data: Visit the Common Crawl website at `https://commoncrawl.org/the-data/` to browse the various crawl archives, their metadata, and understand the different file types (WARC, WAT, WET) available.
- 3
Access Data via AWS S3: Utilize the AWS Command Line Interface (CLI) or an S3-compatible tool to download specific segments or files. Common Crawl data is hosted on AWS S3, allowing direct access to petabytes of web content.
- 4
Process Web Archive Files: Employ tools and libraries designed for WARC, WAT, and WET files (e.g., `warcio` in Python, `cc-pyspark` for large-scale processing) to extract, filter, and prepare the data for your AI or LLM training tasks.
