Twitter Sentiment Analysis

Social media, such as Facebook and Twitter, was a significant focus of Big Data. Utilizing Hadoop and AWS, I did a Sentiment Analysis of Twitter Data, concerning a series of events around the dismissal and subsequent re-hiring of U.Va. President Sullivan, in the summer of 2012. My data source was approximately 52,000 tweets collected by the U.Va. Library. The analysis result was presented in an infograph and an interactive data explorer showing the interplay of Twitter users centered around Larry Sabato, the most prominent influencer identified during the summer.
