What is Common Crawl used for?

Does Common Crawl include reddit?

I think it would be neat to have common crawl pull data off of the same subreddits that reddit does.

It's true, it is common crawl in many different forms. You can find it with a Google search, or use to search it directly. For example, on you can view this search: The 'q' parameter specifies which query you want (you can enter 'reddit', 'reddit-moderators', etc.), and the 'sort' parameter specifies how you want to sort the results.

As far as I know, there are not subreddits that CommonCrawl is already scraping, but I haven't done any digging into what exactly it does scrape from reddit yet. In fact, the Crawldb is itself an alternative to CommonCrawl for the whole web; instead of crawling the web to find URLs, it crawls them by using HTTP headers. It allows for more advanced search and retrieval, as well as meta-data for each page it scrapes. (It's free, and has no ads)

Also, from my search for reddit on CommonCrawl, if I use 'crawl=reddit', I get: (1). (2). As it turns out, both are the same! (I did try out the 'sort=time' option too - it didn't give me anything useful!). However, I don't think reddit actually uses reddit.com/r/. URLs, and the /. Part is what CommonCrawl is looking for when using reddit as its default search.

That is, reddit's search for 'reddit' will just take the first link (using the default) that is not a reddit.

What is Common Crawl used for?

The Common Crawl website has been open for more than a year now.

It is a collection of over 300 million web pages, which are stored and analyzed by Common Crawl and the project team. It is the largest dataset available for free and open access. The main purpose of Common Crawl is the analysis of how information is distributed on the web. This analysis provides information that may be useful for researchers, in understanding the growth of the Internet.

Common Crawl data, like all datasets, can be used for many purposes, such as providing an alternative dataset to a dataset that is not open or public, to complementing one that is open or public, to providing an alternative method for data collection and processing, and to complementing data that was collected in different ways. Common Crawl offers additional services, such as web services, API, mobile apps, and an API-based crawler.

What is the difference between Common Crawl and other crawlers? A crawler gathers web content from the Internet by following links. A crawler starts at a given web address, such as the root page, and then follows hyperlinks to reach other pages on the same website. If it reaches the end of the website, it then begins following hyperlinks to reach other websites. In the case of Common Crawl, there are two crawlers, one for English websites and another for non-English websites. However, because they follow the same link structure, the data from the two crawlers can be used interchangeably.

Common Crawl's data differs from most other crawlers because it has more pages per website (ie, it has a larger number of pages per website). The reason for this is that Common Crawl only crawls English websites. Furthermore, the number of pages that are crawled per website also differs. On average, Common Crawl has a few thousand pages per website, whereas most crawlers usually have hundreds of pages per website. Common Crawl makes this information available online, and it can be downloaded by anyone interested.

The advantage of Common Crawl's data over other crawlers is that Common Crawl data can be obtained for every website.

What does Common Crawl contain?

===============================.

A detailed description of how Common Crawl content is split up and structured will be in another post. Here are the general things you can do with Common Crawl: Indexing: You can index the text from Common Crawl into a local database (which is what your computer does), or into a distributed database that is hosted by Data61, such as Solr or ElasticSearch. Distribution: If you want to redistribute part or all of the Common Crawl to others, you can do that too: using an ftp or http distribution mirror and your software's indexer tools. Visualization: If you are interested in just viewing the raw text, then you can find some of the Common Crawl documents on the Common Crawl main mirror sites by entering them into a web browser. Search: A whole separate set of tools has been developed for searching the Common Crawl. You can start by indexing from commoncrawl.org to use Solr.

The Common Crawl wiki has more information about how to use Common Crawl as a keyword search engine. What else can I do with Common Crawl? =====================================. See the Common Crawl project pages for what other ways there are to use Common Crawl: If you have any questions, please visit the mailing list: or ask @gilligan. Do you work on Common Crawl? Yes, we would love your help. Common Crawl's servers and tools require maintenance.

We are looking for people to help us keep it working and available to others. For more information, see the Common Crawl wiki.

If you need the server to run for your work, we need: An admin account. SSH access to a Linux server (ie SSH keys). Your email address is used for the admin account (and possibly backup mailer, if necessary), but you have no email rights and no other user rights. Your role is to install and maintain some software and servers, keeping the servers well maintained and up-to-date. You might also have to deal with a large number of support requests. Your job is not to develop anything.
