These models typically don’t have hierarchical labels like that, and they apply a softmax to their output - which means /one/ label will be considered correct. (A softmax means taking the exp of your predicted scores, then divide by the sum.)

I know – but there's no technical reason they shouldn't have more complex relationships between labels (assuming you can train that, which I don't know). If we can't get better training data, at least trying to fix the problem at the algorithms (instead of slapping crude filters on the end of them) would be nice.
I agree in spirit but disagree in practice, I think. Like we said previously, the domain is humongous so even establishing meaningful relationships between labels and sublabels is extremely difficult. Many cases are likely ambiguous too, our human understanding isn’t actually hierarchical - it’s much more elusive. It’s a square peg round hole type problem really, humans don’t really think in terms of labels in the first place, we mostly use them for the purposes of language.
