online service, platform, or site that
focuses on facilitating the building of
social networks or social relations
among people. A social network
service consists of a representation of
each user, his/her social links, and a
variety of additional services.

3. Introduction to Social
Networking Sites

describe any Web site that enables users to
create public profiles within that Web site and

5. Origin of social sites
 Social network sites (SNSs) such as such as Fraudster, Cy
World, and MySpace allow individuals to present
themselves, articulate their social networks, and establish
or maintain connections with others.
 These sites can be oriented towards work-related contexts
(e.g., LinkedIn.com), romantic relationship initiation (the
original goal of Friendster.com), connecting those with
shared interests such as music or politics (e.g.,
MySpace.com), or the college student population (the
original incarnation of Facebook.com).

6. 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 CentralityThe degree an individual is
near all other individuals in a network (directly
or indirectly). It reflects the ability to access
information through the network .

7. Types of social networkers
• Alpha Socializes – (a minority) people who
used sites in intense short bursts to flirt ,
meet new people, and be entertained.
• Attention Seekers – (some) people who
craved attention and comments from others
,often by posting photos and customizing
their profiles.
• Followers – (many) people who joined sites
to keep up with what their peers were doing.

8. Types of social networkers
Faithful – (many) people who typically used
social networking sites to rekindle old
friendships, often from school or university.
• Functional – (a minority) people who tended
to be single-minded in using sites for a
particular purpose.

10. Communications can also fill in the social graph
profile

to enhanced information discovery and
delivery.

over your life, leaving little time for
family and friends. Knowing when to stop

Replication of themes from one SN to
another is annoying.

14. DISADVANTAGE

teachers on FB and intrude in teachers’
private lives.

not accept people you don’t know or
protected accounts on Twitter.

15. Privacy
concerns
 Social networking sites provide privacy options but
users are generally unaware or tend to ignore such
concerns
 Stalkers, terrorists, ill-doers, con-artists could benefit
from such issues
 Recent scandals-England :MI-6’s director’s wife puts
up photos of family on facebook.
 Facebook’s controversial decision to make visible
relationship actions to entire social group

17. Safety Issues
 Facebook does not have parental controls but My Space does have
parental controls
 MySpace requires members to be at least 14 years of age to join their
site.
 Facebook requires members to be at least 13 years of age to join their
site.
 MySpace uses IP addresses to manage their website, track member
usage and market the user information to their third party advertisers.
 Facebook’s advertisers download marketing trackers or “web beacons”
to your computer to identify where their ads are most effective.
 Personal information collected by MySpace is openly shared among
users so that they may communicate with each other. MySpace clearly
expresses in their policy that you are sharing your information at risk.
 All private information given to Facebook is not sold or shared with
third party advertisers or marketers.

18. Steps to Safety
 Keep personal information private
 Use a nickname that doesn’t identify
location, gender, age
 Only add friends you know in real life
 Alter pictures to remove identities
 Share profile and photos only with friends
 Ignore harassing or rude comments
 Never post sexually provocative photos

19. More Steps
 Never meet with someone you only
know online
 Don’t post information, photos, videos
you may later regret
 Use privacy settings to limit access
 Online choices have offline
consequences
 Once posted it is
online, somewhere, forever
