I work with Palantir Foundry stack, and I awfully think that this is the best implementation of semantic web principles I could ever imagine.

And the current trend is really to connect the AI layer of Foundry with the ontology layer.

Note: after rereading your comment, I must admit that Foundry enforces data co-locality and model co-locality (==a unified centrally managed ontology). Which are NOT what the semantic web wanted.
