4. What is Social Network Analysis?
Social network analysis is

is created by relations
and the patterns formed.
Social networks are
formally defined as a set
of nodes (or network
members) that are tied by
one or more types of
relations.
5. Relationships
1. Where one person is
connected to another person.
2. Nodes (“Actor” ) or people
in the relationship
3. Edge (relationship
connecting nodes)
4. Clustering or community
6. Key Metrics
Helps to identify the most
critical nodes in a graph (i.e
most influential or popular
person in a network) –
Number of direct
connections that
individuals have with
others in the group
(Degree Centrality).
7. Key Metrics
Betweenness
centrality measures the number
of times a node lies on the
shortest path between other
nodes.
For finding the individuals
who influence the flow around
a system and have a powerful
position in the network.
