Aylien is a tool for determining different strata in data. The taxonomy is my favorite, and when testing it out, it was great at identifying the roots of the language used in various web pages. They also provide sentiment analysis among other features in their growing toolset.
It’s also great that you can play with the tool right on their site, no sign up. This means you can quickly run some tests to see if their product is going to be helpful. The value for being able to categorise data quickly should never be underestimated.
I tested theories with the free api, and found it fine for the subject matter I was dealing with (don’t you just love NDA? 😉
If you want to classify masses of data, it’s perfect
It can be fooled like any AI, but the success rate is very high.
