That is exactly replicable in SPARQL against DBPedia (and probably Wikidata).

It's also fairly useless in that it doesn't give the "commonsense" answer of London as the first result and commonsense is what Cyc has always been supposed to do. (And yes I understand that CityOfLondonEngland probably has a plain English label too).
