One example of an unexpectedly rich and deep tagging ontology is the Danbooru "Anime" image board [NSFW] https://danbooru.donmai.us/ https://danbooru.donmai.us/

I know this is not reddit. But why do you know even know this link and its tagging system...

  I'm not scared away by things that might offend the puritanically inclined and I'm interested in ontologies and this is a fascinating one. There was some drama about someone training a Stable-Diffusion-alike by ripping their dataset that brought it to my attention.

  Danbooru is one of the most popular anime image board. Anyone who's into Anime (not just for hentai) probably knows.

There is a safe-for-work, or at least safer-for-work version of the site: https://safebooru.donmai.us/ https://safebooru.donmai.us/ (It is of course based on the tagging system: every post is tagged by its "safeness" level.)

Yeah, danbooru or similar image boards basically have all the things talked in this tweet thread. They have tag aliases, meta-tags and so-called "tag implications". The last one is basically sub-tags but with more flexibility and dead simple to implement: if A implicates B, then tagging an image with A will automatically tag it with B. So you can tag "American Male Novelist", and then the system will automatically add "American", "Male", "Novelist", "Writer", etc. (after such implications were added). It much easier than Wikipedia's categories, but Wikipedia's way is of course intentional because categories is meant to have a stronger hierarchy than mere tags.

  How much content they've actually put in their tagging system is just as interesting as how the tagging system works.

    And the content itself, I'd say. But yeah, I've always been impressed by how detailed and specific their tags were. That's A LOT of work! The power of porn, I guess. And as an added bonus, those tags now power AIs able to generate custom hentai on demand!

      Unfortunately, since their tags are so abundant, most of them (mainly the "too specific" ones) are far from exhaustive/complete in term of being actually used. And things like hair colors are extremely subjective so you're not sure if an image is going to be tagged as brown_hair or red_hair. If you want to find some images by tags, you better stick with more generic ones.
