By: Dipanjan Sarkar, Raghav Bali

Overview of this book

<p>With powerful features and packages, R empowers users to build sophisticated machine learning systems to solve real-world data problems.</p> <p>This video course takes you on a data-driven journey that starts with the very basics of R and machine learning. You will then work on three different projects to apply the concepts of machine learning. Each project will help you to understand, explore, visualize, and derive domain- and algorithm-based insights.</p> <p>By the end of this course, you will have learned to apply the concepts of machine learning to data-related problems and solve them with help of R.</p> <p>All the code and supporting files for this course are available on Github at<br /><a style="color: #fa8d11;" href="https://github.com/PacktPublishing/R-Data-Analytics-Projects" target="blank">https://github.com/PacktPublishing/R-Data-Analytics-Projects</a></p> <h1>Style and Approach</h1> <p>The course is an enticing journey that starts from the very basics and gradually picks up the pace as it unfolds. Each topic is explained with the help of a project that solves a real-world problem hands-on, thus giving you a deep insight into the world of machine learning.</p>

Sentiment Analysis Upon Tweets – Polarity Analysis
Polarity is the positive, negative or neutral classification of the piece of text in consideration. The degree of polarity helps us analyze the extent (or degree) of positivity (or negativity) in the text. In this video, we will analyze tweets and score each of them based on the polar words identified in each of the tweets. - Extract tweets based on selected search terms or Twitter handles - Load list of positive and negative words to be used for polar word identification - Assign a polarity score based on difference between positive and negative matches
