Centrality Measures

Centrality measures are techniques used in network analysis to identify the most important or influential nodes within a network. Think of a social network: individuals with high centrality are those who connect many people or hold strategic positions within the network. Common types of centrality include degree centrality (number of direct connections), closeness centrality (how quickly one can reach others), and betweenness centrality (how often a node acts as a bridge between others). These measures help us understand the dynamics of relationships in various contexts, from social interactions to transportation systems.
