Short answer is no. Spent many years (>10) listening to people explain how semantic technologies would transform Academic Publishing and make research more useful. Failure in my opinion because - nobody valued it enough to pay to have it done correctly, academic papers have a shelf life, academic papers often contain inaccurate information. Academics publish because it is required not because they have useful info to communicate. In most cases it is the least pleasant part of research.

I have seen many more useful tools come out of LLM in the short time it has been available than the entire 10 years working with academics using RDF, Ontologies etc. RDF is too difficult to use and has inadequate tooling. LLM is only going to get better.
