There is https://commons.wikimedia.org/wiki/User:CategorizationBot but it is inactive for long time :(

I'm interested in this. It's high time we reincarnate this! Thanks for the help @Steinsplitter. If you find any resources or pointers, please do share as I think it would be good to keep working on this so as more and more content keeps coming, at least 20% of it keeps getting categories :)

The bot is no longer operating because:
https://commons.wikimedia.org/wiki/User:CategorizationBot#Why_isn't_the_bot_running?

Maybe @Multichill can share the code so that people can get an idea how the logic works.

Please could some one share the link to the bot repository? Just checked on the frequently asked questions and it seems the maintenance of the bot has stop.

Yeah

@Multichill, do you mind? :), let's do this :)

So I stopped operating the bot back in 2015 because the time it would cost to fix it didn't add up with the (negative) feedback.
If there are multiple people who are willing to help out here I'm more than happy to invest a bit of time to set the thing up again.

If you look at https://commons.wikimedia.org/wiki/User:CategorizationBot#Process you'll see it's basically three parts:

1. Find uncategorized files
2. Try to get uncategorized files categorized
3. Notify users of newly uncategorized files

The first job is part at Pywikibot, see https://www.mediawiki.org/wiki/Manual:Pywikibot/imageuncat.py . It ran once a day with the -yesterday option.

For the second (categorization) job:

• https://github.com/multichill/toollabs/blob/master/bot/populate_category.py
• https://github.com/multichill/toollabs/blob/master/bot/loose_category_from_gallery.py
• https://www.mediawiki.org/wiki/Manual:Pywikibot/imagerecat.py These scripts will be broken or at least not maintained for a long time. For example the imagerecat.py references a toolserver url (see T195079) and the overcategorization filter is broken (see T110833)

Third part can probably just be fired up again if we want it ( https://github.com/multichill/toollabs/blob/master/bot/notify_uncategorized.py )

So basically the re-categorization has to be written from scratch based on Wikidata and we have to figure out something for the overcategorization.

Thanks for the wonderful information @Multichill. Let's digest the information and then revert to you with next steps. Thanks :)

Hello @Multichill, after some digging, the first part has already been handled by Pywikibot right? So we don't need to touch it? Or is there something to be done there?
