Sentiment Analysis is the extraction of emotions from written or spoken sentences to get a broader and clearer view of the user`s point of view. Their emotions significantly impact people`s lives. Organizations can benefit from these feelings by gaining enormous earnings, the confidence of their clients, and their devotion. Sentiment analysis is gaining popularity in implementing better CRM functionalities for large and small firms. This paper presented a comprehensive literature review of various Indian regional Languages. Moreover, it presented challenges like Explicit rejection of feelings, diagnosing sarcasm, etc. This paper also provides future direction for improving the result of accuracy by the right mix of algorithms.
