Centrality Measures
Centrality Measures are used to identify key topics in a network:
- Centrality-Measures
- Degree Centrality: Represents topics frequently mentioned or linked to others.
- Closeness Centrality: Highlights topics that act as important hubs, spreading information quickly.
- Betweenness Centrality: Identifies topics that connect different sections of the network.
- Eigenvector Centrality: A measure of a topic’s importance, based on how connected it is to other influential topics.
Using Centrality to Understand Influence in Social Networks
A notable application of centrality measures is PageRank, a concept popularised by Google to rank web pages based on their importance. In the context of social network analysis, PageRank can be applied to topics, assigning higher scores to those frequently referenced by other influential topics.
By analysing these centrality measures, companies and researchers can identify which topics dominate a conversation, serve as key influencers, or are highly interconnected with other important themes.
