What makes social media social?
• Who makes it?• Who consumes it?• Who owns it?/Who profits from it?• Who or what makes it successful?• How to harness the swarm?• How to map and understand its dynamics?
– How do people and groups vary?– Who links to whom?
• What is next for social media?

Each user can directly control smallest units of content.
Each user controls medium sized blocks of content that can only indirectly alter or be altered by other user’s content in a larger shared data structure.
Each user controls a block of content, rarely edited or modified by others with only associative linkages.

Collective Action Dilemma Theory
• Central tenet– Individual rationality leads to collective disaster
• Phenomena of interest– Provision and/or sustainable consumption of collective
resources– Public Goods, Common Property, "Free Rider” Problems,
Tragedies– Signaling intent
• Methods– Surveys, interviews, participant observation, log file analysis,
computer modeling
(Axelrod, 1984; Hess, 1995; Kollock & Smith, 1996)
Community Computer Mediated Collective Action

Interactionist Sociology
• Central tenet– Focus on the active effort of
accomplishing interaction• Phenomena of interest
– Presentation of self – Claims to membership– Juggling multiple (conflicting) roles– Frontstage/Backstage – Strategic interaction– Managing one’s own and others’ “face”
• Methods– Ethnography and participant observation
(Goffman, 1959; Hall, 1990)

• Central tenet – Social structure emerges from – the aggregate of relationships (ties) – among members of a population
• Phenomena of interest– Emergence of cliques and clusters – from patterns of relationships– Centrality (core), periphery (isolates), – betweenness
• Methods– Surveys, interviews, observations,
log file analysis, computational analysis of matrices

Social Network Theoryhttp://en.wikipedia.org/wiki/Social_network

SNA 101• Node
– “actor” on which relationships act; 1-mode versus 2-mode networks• Edge
– Relationship connecting nodes; can be directional• Cohesive Sub-Group
– Well-connected group; clique; cluster• Key Metrics
– Centrality (group or individual measure)• Number of direct connections that individuals have with others in the group (usually look at
incoming connections only)• Measure at the individual node or group level
– Cohesion (group measure)• Ease with which a network can connect• Aggregate measure of shortest path between each node pair at network level reflects
average distance– Density (group measure)
• Robustness of the network• Number of connections that exist in the group out of 100% possible
– Betweenness (individual measure)• # shortest paths between each node pair that a node is on• Measure at the individual node level
• Node roles– Peripheral – below average centrality– Central connector – above average centrality– Broker – above average betweenness

HUB-AND-SPOKE OF DECEIT: When Enron employees communicated about legitimate projects, e-mails were reciprocal and information was shared widely (right), but communications about an illicit project (left) reveal a sparse network with a central, informed clique and isolated external players.Brandy Aven, CMUhttp://www.sciencenews.org/view/generic/id/330731/title/Information_flow_can_reveal_dirty_deeds

Goal: Make SNA easier
• Existing Social Network Tools are challenging for many novice users
• Tools like Excel are widely used• Leveraging a spreadsheet as a host for SNA
lowers barriers to network data analysis and display
