Re: I am endlessly fascinated with content tagging systems
#32I’ve written a tagging system from scratch for an existing system and it was one of the most interesting things I’ve worked out. I had total control over how it was implemented and I think I came up with a really nice, minimalist, scalable way to tag things, and to search them.
Care to elaborate? I'm also working on a categorization/tagging system - albeit a simple one - and I find myself in a struggle to keep it accessible enough to use on one hand and advanced enough to actually add value on the other hand.

#33This seems like one of those Eternal Problems that people, whether librarians, programmers, or hobbyists, stumble across, think they'll make headway in, then discover that they've really managed to progress just a few feet across a vast and hostile surface of landmines, pitfalls, and lures. Each "obvious" step (I'll have parent relations to define a context!) is only yet another bargain with the Devil, who laughs at your precautions.

#34I think tag aliases are fine, but in my opinion, tags should not have hierarchies. That is just opening the can of ontology worms, and most systems are ill-equipped to deal with ontologies...including ontological systems. Tags are just dumb strings which label data. They are basically KeyValues, where the value is just always equal to True. We don't think of KVs as hierarchical unless they are explicitly a path strin…
Optional forests of hierarchy trees are where it's at. Essentially don't encode everything into one gigantic one.
Sometimes you know that users are going to tag `laptop` a bunch and want that to also drag in `personal computer` (but not all `PC`s are `laptop`s) or that `blue dress` is also a `dress` and don't want to hard code special cases.
That said, if you are going to do this, then you must have it controlled by an admin/moderator. Maybe allow for hierarchy request submissions but have it moderated. There is at least one public system where this just works to my knowledge and a bunch of self-hosted ones as well.
Re: I am endlessly fascinated with content tagging systems
#35A very insightful thread by Hillel Wayne on content tagging systems and their challenges. Their ubiquitous use (in library and information sciences, and popular social networks like Instagram, Twitter, and Pinterest), their deceptive ease of implementation, and "obvious advantages" over hierarchies/folders, means that almost every developer has (or will) run into them at one point or another.. Feel free to comment wi…
> It's especially interesting with good case studies for how to model an advanced tag system in a graph database
I wouldn't accuse it of being a good tag system, nor a true graph database, but one thing to look at is Semantic MediaWiki. It's a MediaWiki extension which takes Categories as a starting point, and extends it quite far with e.g. relations and key-value pairs.
One interesting feature of Semantic MediaWiki is called "Concepts" which are essentially "computed tags." They can be used in place of Categories in most places, but while Categories are set by editors on a piece of content, Concepts are defined by a query against Categories or other properties. This can help bridge gaps between different types of tags that represent different ways of thinking about the content.
Re: I am endlessly fascinated with content tagging systems
#36> I can't find anything on how to design and implement anymore more than the barebones basics of a system. All of this stuff (horse/horses etc) is extensively discussed, maybe look under "taxonomy" or "ontology". Now, whether you want to use any of those solutions or not or find the discussion useful or not... if you aren't finding anything about it at all, you aren't looking in the right places.

Re: I am endlessly fascinated with content tagging systems
#37A few months ago I worked on some proof-of-concept code for searching tagged data: https://github.com/aaviator42/Cha
I now work full-time in a role where part of my duties is designing a content tagging system and its search functionalities. It's very interesting and fun! Lots of puzzles.
How do you weigh different tags? How do you do fuzzy searching ('city' should match with plural ('cities'), misspellings ('citys'), etc)?
How do you program the system so that 'hotdog' is not matched with 'hot' and 'dog'? What about synonyms? What about regional terminology and synonym tables?
Then there's one-to-one and one-to-many and many-to-one mapping.
As a side project I'm also working on a beta public search engine that I'll launch on HN sometime in the next year or so, where I'm having similar puzzles.

#38I am endlessly fascinated by how twitter has now become a dumping ground for complex topics that are difficult to read and follow. But what happened to the old blogs?
Re: I am endlessly fascinated with content tagging systems
#39I can't wait for the author of this thread to discover the AO3 tagging system, which is, frankly, a masterpiece that demonstrates how effective community management can lead to extremely good tagging and categorization, with very little miscategorization. https://www.wired.com/story/archive-of-our-own-fans-better-t... https://archiveofourown.org/faq/tags
They mention it 4th post in the thread.
I never heard of it though, what's so good about it?
Re: I am endlessly fascinated with content tagging systems
#40"Advice: don't let the tag predicates refer to other tags"
But then how would I search by the tag of all tags that do not tag themselves???
