In the book "How to take smart notes" by Sönke Ahrens, there's a lot of thought given on the real value of tags. I'd say the problem you describe happens because you are trying to create a taxonomy using tags. Classifying the notes using tags can feel rewarding in the short term, but it's not useful in the context of a linked notes system.
When creating tasks, the main question that is answered is "in which contexts would I like this note to show up?". The answer to this question is completely subjective. If, for instance, you were doing research for game level design, it makes sense for the systems architecture notes to be tagged with "game engine", "achievements", "quick save", or anything else that you will want to look up later on. The Napoleonic architecture notes could be tagged as "level design", "gameplay cues", or "side quests".
As you can see, these tags would be different for every person, and that's kind of the point. Two people can read the same content, and take the same note from it, but the intended purpose could still be completely different, and that would show up in the tags.
