What is a Network? node Web Definition : A set of nodes, points, or locations connected by means of data, voice, and video communications for the purpose of exchange. Link

Social Networks A social network is a description of the social structure between actors, mostly individuals or organizations. It indicates the ways in which they are connected through various social familiarities ranging from casual acquaintance to close familiar bonds.

Social networks and KMS Why Social Networks in KMS? People Technology Organization Processes KM Knowledge Management involves people, technology, and processes in Overlapping parts.

Social Network Analysis We measure Social Network in terms of: 1. Degree Centrality: The number of direct connections a node has. What really matters is where those connections lead to and how they connect the otherwise unconnected. 2. Betweenness Centrality: A node with high betweenness has great influence over what flows in the network indicating important links and single point of failure. 3. Closeness Centrality: The measure of closeness of a node which are close to everyone else. The pattern of the direct and indirect ties allows the nodes any other node in the network more quickly than anyone else. They have the shortest paths to all others.
