The program scans every new dump for over 30 languages and creates a list of articles with errors.
For a few Wikipedias, the program scans newly revised articles daily, to create a new list for users, omitting already-corrected articles.
A specific interface – here for the English project – facilitates correcting problems detected by the program in the following three levels of ranking priorities errors. It helps keep the error lists updated in near real time by providing some statistics on corrections made recently.
