This page documents a completed research project.


This page is analysis of revert time in several wikis.

Methods

edit

It basically was running the mwreverts script on dumps of several wikipedia and when the dump is redacted to a dataset of reverted/reverting edits with their metadata, It allowed us to run analysis on them. I ignored any revert that took more than 48 hours to happen.
