So far in the chapter, we have applied text analysis techniques to extract a lot of information about the Google brand page on Facebook. Now, we'll use some advanced techniques like emotion analysis to get more qualitative about the content. In order to achieve, this we'll be using the Alchemy API, which is now a part of IBM. The Alchemy API has an interesting set of tools that allow you to perform semantic analysis and natural language processing.
We will now have a brief discussion on Emotion Extraction.
Alchemy API became a part of IBM Watson technology, which currently is offered on the Bluemix platform.
The service, called AlchemyLanguage
, is a collection of text analysis functions that derive semantic information from your content. It can be accessed via API calls and a rich portfolio of methods.
