  1. Hey,nice article !
    does this application analyses only English language ?
    if yes how could i make it a multiple language analyzer!

  2. Thanks soo much for this! Exactly what I needed to help a student doing some text sentiment analysis for programming in Indesign. Stripped down the code to just make a simple endpoint API that could be called via GET… dubbed [sentilyzer](https://github.com/ffd8/sentilyzer)

  3. One of the best and comprehensive article on Building a sentiment analysis app, I am bookmarking it so I can read it again. Thank you Ebenezer Don, You really inspired me to learn more.

  4. Thanks for article, I get following messages when installing spelling corrector. Any idea how to resolve?
