Sentiment Analysis

What are the common challenges with which sentiment analysis deals? What are the most popular application areas for sentiment analysis? Why?

Your response should be 250-300 words. There must be at least one APA formatted reference (and APA in-text citation) to support the thoughts in the post.  Do not use direct quotes, rather rephrase the author’s words, and continue to use in-text citations. 

Pls, use the references from textbooks, not internet sources.
