Why is Mirascope failing on NER beyond 2 levels?

[willbakst]

Marie Stephen Leo posted about Mirascope on LinkedIn and noted that it missed a single deep nested field in the third nested level of an NER task (and it looks like in the original post before this one that fructose succeeds for this task).

Why is this the case? I think this is something worth looking into. If fructose can do it, then there must be a way for Mirascope to do it without having to wait on model improvements.

Want to use this as an open discussion as I look deeper into why this might be the case and how we can make Mirascope structured extraction as good as possible (with solving this failure as the next step).
