Topic Modeling is also very widely used domain under the sentiment analysis. Topic modeling is a form of text mining, a way of identifying patterns in a corpus. You take your corpus and run it through a tool which groups words across the corpus into ‘topics’. or you can say "It's a method for finding and tracing clusters of words (called “topics” in shorthand) in large bodies of texts.”
