Trends In Social Networking

Dr. Marc A. SmithChief Social Scientist, Connected Action Consulting Group• Marc Smith is a sociologist specializing in the social organization of online

communities and computer mediated interaction. He founded and managed the Community Technologies Group at Microsoft and led the development of social media reporting and analysis tools for Telligent Systems.

• Smith now leads the Connected Action consulting group. The Connected Action consulting group applies social science methods in general and social network analysis techniques in particular to enterprise and internet social media usage.

• Smith also co-founded the Social Media Research Foundation, a non-profit devoted to open tools, data, and scholarship related to social media research.

• Smith received a B.S. in International Area Studies from Drexel University in Philadelphia in 1988, an M.Phil. in social theory from Cambridge University in 1990, and a Ph.D. in Sociology from UCLA in 2001.

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

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

Distinguishing attributes of online social roles

Answer person• Outward ties to local isolates• Relative absence of

triangles• Few intense ties

Reply Magnet• Ties from local isolates often

inward only• Sparse, few triangles• Few intense ties

The State Of Social Network Analysis

Topic: State Of The Market & Profession

• What’s our current understanding of social networks and SNA?• What’s emerging in terms of graph engines and standards

that we should know and care about?• Sunbelt 2010 conference just concluded – findings?

31

The State Of Social Network Analysis

Topic: Risks – The Dark Side of Social Networks & SNA

• With all this social data out in the public – what are the risk aspects we need to be concerned about?

• Social network sites like Facebook and LinkedIn• Social media and the impact of Twitter• Social feedback (ratings, “like”, “favorite”, ranking, tags…)• Mobility and use of location data• Connecting identity facets and correlating the results (e.g., social roles)

32

The State Of Social Network Analysis

Topic: Implications of SNA to the IT organization

• How do social networks, SNA, and the collection of massive amounts of social data mean to data management strategies (e.g., business intelligence, “data clouds”)?

• Related enterprise concerns:• Intellectual property• Confidentiality• Privacy• Compliance

• What skills are now needed for IT organizations to play a role in SNA?

33

The State Of Social Network Analysis

Topic: Social Media

• How has social media re-kindled interest in SNA – what are the implications of having access to so much public data (re: how do organizations best leverage this information)?

• You’ve done some visualizations for this conference using the #CAT10 tag – what did the results show?
