I tested most of the solutions a year or two ago before AWS rolled out Amazon Comprehend. I found that Google’s API combined with some code and open source packages ended up being additive for entity recognition, classification, and semantic text. Unsurprisingly, Google’s custom search API’s are also worlds better than the other places, as is it’s Maps API. I haven’t tried any of the image classification API’s, but I won’t be surprised if Google won here too.
