This dovetails into another “bluesky” discussion about Natural Language Processing. You are speaking doing the same ‘noun’ isolation portion manually.
The linker in the in Note Editor and the marquee tagger in the photo tagging gramplet share a lot of conceptual functionality. Both similarly both fall short of supporting convenient workflows.
In the photo tagger, you draw marquee rectangles and a list appears down the right side where it must be associated with a Person object.
In the Linker of the Note Editor, you highlight a block of text and select an object (of any type) with that text.
Both are part of the way there for work flow. In each, you do one-by-one linking. (You cannot outline your workflow – highlight everything to create a worklist, then process the list by grouping/prioritizing or annotating before linking.) And while the phototagger supports face detection on some OSes, the Note Linker neither has NLP noun detection nor the convenient linked list in a side pane.
And the Note Linker has a nasty bug where it overwrites any clipboarded data with the highlighted text. (I suppose it might be a feature intended to help with pastable text for searching in the object selector. But that could/should have be done with another mechanism rather than overwriting the clipboard.)
