About the book

This book treats Sentiment Analysis as a separate discipline to highlight the role of mining the public opinion while exploiting the trending features like emojis. Many people use the words, Emoticons and Emojis interchangeably. Though they both represent expressions which people miss in non-verbal conversation, there’s a slight difference between the two which is discussed in this book. Moreover, the book advocates the notion of giving due respect to the graphical cues which are generally chopped off by the traditional approaches to Sentiment Analysis.
This book has been written in lucid manner and is packed with practical approaches of extracting, processing and mining opinions. It discusses all the sentiment analysis approaches and compares their performance. Each chapter starts with the learning objectives and ends with a summary containing a quick review of important points discussed in the chapter.
The key feature of the book is a fully devoted case study on Sentiment Analysis which shows the detailed end to end process and visualize results. The case study explains in detail the reviews extraction process, pre-processing, feature selection/creation/ extraction, model selection, implementation and graphically visualizing the results. This will help both students and those already working in industry to understand the end to end process and use them practically.
