Hi flip,

I'm hacking at chirp and am interested in a follows b, hashtags, and urls. What would be extra sweet would be timestamps on the follow relations, if you crawl the same person over time and we can see how that network evolves. Thanks for making the data available.

Hi all,

I'm pleased to announce that Infochimps is making datasets from our massive scrape of the Twitter corpus available for Chirp Hack day devs.

There's a big opportunity for apps that draw on the historical record and *structure* of twitter -- apps that require a global perspective and intense computation. The following are available to mash up against other datasets from infochimps.org or even just to bootstrap-seed the database for your Hack Day application. We also have a 30-machine cluster up to do further extractions, so if you have something really interesting you'd like to pull please let me know.

Reputation Metrics from Reply and Follow graphs Uses algorithm similar to pagerank to derive reputation, one using the a_follows_b graph and one using the a_replies_b graphs Reply/retweet/mention graph Every observed Reply, retweet, or mention seen in a 1.6B-tweet sample (about 15% of historical record): a_[rel]_b, user_a_id, user_b_id, tweet_id Twitter Users by Background Color The number of users with each background color: color code, user count Twitter Users by Friends Count The number of users with a given number of friends: number of friends, user count Twitter Users by Followers Count The number of users with a given number of followers: number of followers, user count Twitter Users by Created At The number of users whose accounts were created in a given month/day/hour along with the earliest seen ID in that hour: timestamp to month/day/hour, user count
Smileys Smiley faces with user, date, tweet_id
Hashtags Hashtags with user, date, tweet_id
TweetUrl URLs with user, date, tweet_id
Twitter Users by Location The number of users in a location string (as provided by the user in their profile). location, user count Stock Tweets Tweets that include the stock symbol tag convention of $STOCKNAME or $$. The tweet is listed for each time a tag is used in the tweet. stock_tweet (resource name), symbol captured, tweet object (all things in a tweet) Stock Prices Daily stock prices for the NASDAQ, NYSE, AMEX exchanges 1970-now symbol, open, low, close, high, volume

Parameters for what's available:

a_follows_b             45.8 GB     1,587,838,568
a_mentions_b            29.5 GB       493,682,309
a_retweets_b             1.6 GB        36,022,061
twitter_user             3.1 GB        43,261,388
tweets                 376.0 GB     1,641,624,381

If you'd like access to any of these, or have an idea that needs something /not/ here, please let me know (f...@infochimps.org). We're only opening access to Hack Day devs for now -- but please let us know your ideas so we can show twitter how much demand there is for aggregated access to data.

best,
flip
