I simply haven't gotten Smart Connections to index my vaults successfully, for whatever reason. So I can't give them a proper review.

I'd hope that any inference performed in a given note would take as context not only the full text of the note, but its nearest neighbors—although, frankly, what I really want are the implicit definitions of proper nouns, ie links.

I also frequently generate articles based on the subject's backlinks, ie mentions in other notes.

Both of those functionalities are provided by Obsidian's core featureset, so all that's missing—and what might provide outsized value—is indexing notes based not only on the embeddings of their literal text, but on meta-text such as: the questions they might answer; the definitions of their principle subjects; counterfactual statements they falsify.

All of which would allow the editor to bring up a relevant note when writing/reviewing another–ie the "unknown knowns".

I think this technique is akin to "knowledge enrichment", or "meta-embeddings," but I think actually those terms have lower-level meanings.

Of course, generating these embeddings would make the indexing process slower and more failure prone, and so I'd be even more likely to fail to get it working and call it a dud.
