Weekly seminar series of the Mitchell Centre for Social Network Analysis.
This week speaker: Martin Everett, University of Manchester
A simplified bridging measure for social networks
Valente and Fujimoto (2010) proposed a measure of bridging in networks based on Granovetter’s classic work on the strength of weak ties. They claim that the measure they propose is different from other bridging (and centrality) measures and demonstrate their measure on a variety of hypothetical and empirical datasets. In this talk we critically review their method and highlight some problem. We then go on to show how we can relate the general idea to node betweenness centrality and propose an alternative. This new approach has a number of advantages, first it provides a more robust means to normalize the measure to control for network size, and second, the extended measure is inherently asymmetric thus obviating the need to calculate both in- and out-bridging. Finally it is easier to compute allowing us to develop empirical and theoretical results.
