You could try Semantria API ( ) 3 I first tried it using their free trial. I was able to pull names (they call them entities) and themes that reoccurred in my content. By creating queries you can also tag themon topics present in your group of s. They also have a lot of other analysis features that I was interested in like sentiment analysis and categorization.n nOverall I liked their API which was accessible directly within Excel with their plug-in 3 making it easier to use (thank goodness). I don have a lot of experience with other tools but AlchemyAPI and Chatterbox are some others that may offer what you need although they don seem to offer customization of their output or custom sets of categories and tags.
