SI 301 Chapter Notes - Chapter 3: Nodeb, Social Capital, Embeddedness
Document Summary
Clustering coefficient: is defined as the probability that two randomly selected friends of. A are friends with each other: the fraction of pairs of a"s friends that are connected to each other by edges. Strength of weak ties: bridges and local bridges, an edge is a bridge if deleting the edge would cause a and b to lie in two different components. This edge is literally the only route between its endpoints. Strong triadic closure property: we say that a node a violates the strong triadic closure. 13. assuming the strong triadic closure property and a sufficient number of strong ties(atleast two strong ties), the local bridges in a network are necessarily weak ties. Conceptual span" of social network is directly related to their weakness as social ties. Of these, only c is a neighbor of both a and f, so the neighborhood overlap is 1/6: local bridges have an overlap of 0.
