If we speak specifically about IBM Cloud vs AWS, we use the Natural Language Understanding API in IBM Cloud and as far as I know the equivalent AWS offering, Comprehend, doesn't provide named entity disambiguation nor links to knowledge graphs (IBM links to DBpedia).

MS and Google do provide those features though.

Unfortunately, that API changes regularly and often in undocumented ways that causes breakages for customers. Its really a lot of fun to deal with when suddenly a bunch of automation breaks and it turns out an unannounced push fundamentally re-writes foundational API calls.
