Text Mining: TF-IDF & Sentiment Analysis

Every month the Indian Prime Minister Narendra Modi gives a radio address to listeners. I collected those speeches with rvest and created a shiny app to allow users to explore different aspects of the corpus, such as word frequencies, sentiment, and TF-IDF. Find the app at the button above or link below:

Related to this project, I also wrote a short post introducing the tidytext package found on the Social Cops blog.
