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.

Results[edit]
