Chicago Politicians on Twitter
The document outlines a project by researchers from the Illinois Institute of Technology analyzing the Twitter activity of Chicago politicians, focusing on network and content analysis. It includes statistics on engagement, types of messages, and inter-coder reliability for content categorization.
