34. • Reduce the large quantity of
data into a more concise
representation
• Makes it much easier to
understand what is going on
in a group
• Once the network is
discovered, we can find out:
• How do people interact with
each other
• Who are the most/least active
members of a group
• Who is influential in a group
• Who is susceptible to being
influenced
• Much more!
