About this Flexdashboard

This is Part 3 of my work with the sentiment movie review dataset from the paper by Bo Pang and Lillian Lee, A Sentimental Education: Sentiment Analysis Using Subjectivity Summarization Based on Minimum Cuts, Proceedings of the ACL, 2004. While I like my R Notebooks, this R Flexdashboard gives me the ablity to interact with the dataset without scrolling up and down a page to view the graphs. Using the tabs, I can go directly to the part of the dataset that I am interested in. In this Flexdashboard, I have changed the color scheme used, I cleaned up the dataset more rigorously and I have also added another data visualization graph that is not in Part 1 or in Part 2.

Note: As in my R Notebooks, the graphs in this Flexboard are interactive. Placing the mouse cursor on the graphs will show information about the dataset that was used. If you cannot see the wordclouds, refresh the browser.
