The graph algorithm described in the blogpost is more related to label propagation (which is more than 10 years old), than to "retrofitting". And the Google paper linked in the blogpost is citing the relevant literature correctly.

I probably sounded more accusatory than I should have, and I apologize for that wording.

But I do think this is much more like retrofitting than like label propagation. It's the vectors that are being propagated, as I understand it, not labels.
