Centrality is a measure of a node’s significance¬†within a network by trying to capture how “central” it is within the network of connections. Centrality gives us some idea of the node’s position within the overall network, it is also a measure that tells us how influential or significant a node is within a network although this concept of significance will have different meanings depending on the context. There are a number of different metric systems for trying to measure centrality these include: Degree connectivity, closeness centrality, betweenness centrality, eigenvector centrality among others.
