For examining the various groups in various subreddits. /u/RedditAnalysisBot is open source. You can view it here.
I filter posts by flair now.
flair:"SubredditName"
I open sourced the bot because:
- If there's a flaw it's more likely to be noticed
- It offers some transparency
- If I disappear and someone wants to run more drilldowns they'll be able to without building another bot from scratch
How does the bot work?
Updated 2014-09-05
- First, it grabs the latest 1000 threads from a subreddit's hot queue.
- Second, it compiles a list of usernames from the creators of those threads along with the people commenting in them (while ignoring submissions/comments with a karma score of -4 and lower).
- Then, the bot crawls through their last 1000 comments/submissions in their user history to find out where else they post (also ignoring comments/submissions with a karma score of -4 or lower) while keeping tally to see which subreddits have the highest overlap.
- Finally, the bot calculates the similarity between subreddit samples.
How to calculate similarity between two subreddits:
sqrt(AB * BA) / sqrt(A * B)
AB = overlapping users from subreddit A
BA = overlapping users from subreddit B
A = number of users found by the bot in subreddit A
B = number of users found by the bot in subreddit B
Other stuff:
- I excluded default and former default subreddits
I take requests for specific subreddits.
