Right now, I want all the edits to user pages and user talk pages, 2010-2013. But as I keep going with this project, I may want to expand a bit, so I figured if I was going to run the wikihadoop software, I might as well only do it once.
I'm hesitant to do this via web scraping, because I think it'll take much longer than working with the dump files. However, if you have suggestions on how to get the diffs (or a similar format) efficiently from the dump files, I would definitely love to hear them.
I appreciate the help and advice!

I agree with Klein. If you do not need to exploit the entire Wikipedia database, requests through a python scraping library (like Beautiful Soup) are certainly sufficient and easy to set up. With an aleatory algorithm to select the "ids" you can create a fine sample. PCL

Hi Susan,
Do you need the entire database diff'd? I.e. all edits ever. Or are you interested in a particular subset of the diffs? It would help to know your purpose.
For instance I am interested in diffs around specific articles for specific dates to study news events. So I calculate the diffs myself using python on page histories rather than the entire database.

I'm looking for a dump from English Wikipedia in diff format (i.e.each entry is the text that was added/deleted since the last edit, rather than each entry is the current state of the page).
The Summer of Research folks provided a handy guide to how to create such a dataset from the standard complete dumps here: http://meta.wikimedia.org/wiki/WSoR_datasets/revision_diff But the time estimate they give is prohibitive for me (20-24 hours for each dump file--there are currently 158--running on 24 cores). I'm a grad student in a social science department, and don't have access to extensive computing power. I've been paying out of pocket for AWS, but this would get expensive.
There is a diff-format dataset available, but only through April, 2011 (here: http://dumps.wikimedia.org/other/diffdb/). I'd like to get a diff-format dataset for January, 2010- March, 2013 (or, for everything up to March, 2013).
Does anyone know if such a dataset exists somewhere? Any leads or suggestions would be much appreciated!
Susan
