Subredditor creates visualizations of how subreddits relate to one another
recommender.py one must either populate the MongoDB database with https://github.com/cdated/reddit-crawler, or use mongorestore on the bson in data/dump/reddit.
recommender.py generates a sub-region of the full graph with limits on the breadth and depth of child nodes. The user must specify a subreddit as the root to which parent and child nodes are connected. Output is a graphviz file and optionally a png.
usage: recommender.py [-h] [-b BREADTH] [-d DEPTH] [-r] [-n] [-s SUBREDDIT] [-v] optional arguments: -h, --help show this help message and exit -d DEPTH, --depth DEPTH Tree traversal depth -r, --render Render graph -n, --nsfw Allow over 18 subreddits as nodes -s SUBREDDIT, --subreddit SUBREDDIT Root subreddit -v, --verbose Show debugging
There's already a database (approx 8Mb) in the repo for those who don't want to run the crawler to see the connections. To load it just run the
Generating a graph of subreddits related to /r/wikipedia and /r/python. Render the graph as a pdf with -r (render) flag and limit the number of child nodes to 2 with -b (breadth) flag. When breadth is restricted the child nodes are chosen at random, breadth also decreases with depth to prevent extremely large graphs.
