	# AICC: AI-Ready Common Crawl Dataset
	![](./images/AICC_HF_LOGO.jpeg)
	AICC (AI-ready Common Crawl) is a Markdown-formatted, AI-Ready web dataset derived from Common Crawl data through parsing and extraction. The dataset is generated using the Dripper method, a web extraction technique developed by OpenDataLab.
	- High-quality main content: High-fidelity main content extracted from diverse Common Crawl pages, including challenging types like forums, Q&A sites, and pages with tables or formulas.
	- Precise structured elements: High-fidelity extraction of code blocks, mathematical formulas, and complex tables from real-world web pages, preserving syntax, formatting, and structural integrity.
	- Proven downstream effectiveness: Pretraining a language model on AICC leads to higher accuracy across diverse benchmarks compared to training on datasets extracted with other methods.

	## Dataset Creation
	Raw Html Source This release includes the parsed results from two Common Crawl dumps:
	- CC-MAIN-2025-08
	- CC-MAIN-2025-13

	Dripper Pipeline The detailed pipeline can be found in the [AICC technical report](https://opendatalab.com/):

	## Data Statistics
	The AICC dataset contains only the successfully extracted AI-ready JSON records(each with a `content` field containing Markdown text).<br>
	For reference, the number of original pages in the corresponding Common Crawl dumps is also shown below.<br>
	Note that only the extracted JSON records are included in the released dataset.

	"content": "# Dude Finds Giant Centipede In Daughter's Room & Horrifies People With the Footage\n\nGrowing up in Brooklyn I was always terrified of house centipedes. And why wouldn't I be? The revoltingly speedy unibrow bugs were all over the place. They'd find their way onto my arm at slumber parties, inspiring blood-curdling screams more indicative of a murder than a creepy crawly. I'd find them in my shoes. My mother would tell me they're \"good bugs\" because they eat the \"bad bugs,\" but to me they were the stuff of literal nightmares. Eventually my fear subsided, after having to live in a dank and dark East Village basement where they were a daily sighting. I'd almost forgotten about the critters - until Twitter user@VickGlaze horrified the internet with a video that features a far more sinister-looking centipede.\n\nI almost had set the crib on fire yesterday….Y'all wouldn't believe what I found in my daughters room dawg. I just spent a 50ball at Lowe's on everything pest control. I found where it came in and sealed every window in the crib and some. pic.twitter.com/iAoN7uWYsY\n\n— Miami Vice II (@VickGlaze) July 27, 2021\n\nThe alarmingly large centipede in Vick's video is known by a few names. Some call them Texas redheaded centipedes, others the Giant Desert Centipede. Whatever its called, it's freaking terrifying. And this scared father was not afraid to admit it. In a thread, he details all the measures he took to protect his home, and the terror the creature has struck in his heart. The responses (mostly in solidarity) are almost as entertaining as the video and accompanying story. As for me? I'm feeling pretty damn lucky that I grew up in New York and not in Austin, Texas, where these massive venomous critters roam.\n",
