Sentimental Analysis Algorithm refers to the usage of statistics, natural language processing, and text to identify and extract the text sentiment into categories that can be termed as positive, negative, or neutral. Sentimental analysis is, therefore, the computational treatment of emotions, subjectivity of text and opinion. The present paper provides a comprehensive review of the proposed enhancement of algorithms and some sentimental analysis applications. Some of the areas investigated and presented in the article include emotion detection, transfer learning, and resource building. Sentimental analysis provides an opportunity to arrive at a decision that is binary; you are either for or against the decision. An example of such a binary question can be used on Twitter or political polls, e.g., “Do you support the use of nuclear warheads?” with the option of either answering Yes or No.
