This document discusses using social network analysis to understand social media crowds. It explains key concepts in social network analysis like nodes, edges, centrality measures, and network visualization tools. The document promotes NodeXL as a tool for conducting social network analysis on social media data to understand crowd dynamics at both the macro level of overall structures and the micro level of individual roles. The goal is to provide insights about who the most central and influential users are and how information spreads through the network.
