@WMDE-leszek Thank you. Don't worry, I will request the repo: we need one for this kind of one-shot tasks anyways. @awight @Jan_Dittrich The following is based on `395,680` Wikidata editors and following the corrections as suggested by @awight in T282563#7104580 <https://phabricator.wikimedia.org/T282563#7104580>: - The probability of editor reactivation is `0.08548827`; - Reactivation is defined in the following way: we look at consecutive months since user registration and mark active months (>= 5 edits) as `1` and non-active months as `0`, so the whole user revision history becomes a string e.g. `010001111100101...` - We search for a regex pattern `1+0+1+` in the revision histories; each match is recognized as a reactivation. Here is the distribution of the number of reactivations: 0 1 2 3 4 5 6 7 8 9 10 11 12 361854 18324 6660 3580 2194 1363 869 447 236 101 37 12 3 Obviously a vast majority of editors never reactivate following one month of inactivity, implying that user retention in Wikidata is a serious problem indeed. Again, only item, property, and lexeme namespaces are considered. @awight Thanks again for T282563#7104580 <https://phabricator.wikimedia.org/T282563#7104580>!
