  2. * *(Lin, 2002) Concept Map

  3. Why Social Network Analysis? • Understanding dynamics of information flow • Identifying important actors • Leveraging the best out of existing network • Faster and efficient information diffusion • Greater control over data flow

  4. Prof Anil Gupta’s FB network

  5. Prof Anil Gupta’s FB network Pollinators Bridges

  6. We are looking for…. • Pollinators: Stars of the network • Not necessarily the most popular • A good pollinator has more number of pollinators down stream • Many ways of identifying critical actors • Bridges: Important connections. • May not have a diverse sub-network, but connect to other critical actors

  7. Parameters for Pollinators • Number of outward connections: measured using the metric, out-degree. • Diversity: • A measure of the degree to which the actor can spread the data. • Measured using the betweenness centrality. • No of prominent actors downstream • Measured by eigen vector centrality • Depth: Depth is defined here to signify how much distance (in terms of degrees of separation) the information can flow thru an actor. • The smaller the closeness centrality the more isolated(or distant) from the network, the actor is. • Can be measured by the negative value of the closeness centrality of the most distant actor in the network. • Density: Dense network in one city
