  2. Outline • Introduction • Preliminary • Method(Model) • Experiment • Conclusion

  3. Introduction In this research, we propose to formalize the notion of social capital by creating a mathematical model of social capital that incorporates the mobilization of social resources through purposive actions.

  4. Preliminary Social capital is not possessed by individuals, but resides in the relationships individuals have with one another. • bonding social capital • bridging social capital

  5. ESNs • An explicit connection links individuals together based on a well-defined relationship ex. “A is a friend of B” OR “A collaborate with B” IANs • An implicit connection links individuals together based on loosely defined affinities ex. “similar hobbies” OR “shared interest”

  6. Sample Individuals and Attribute Sample Hybrid Network IAN ESN

  7. IAN Link ESN Link

  8. Method We define actual bonding social capital between iand j as the product strength Implicit=0or Explicit=0 Implicit=1 and Explicit=1

  9. Method • Bridging social capital Implicit=0andExplicit=0 Implicit=1 and Explicit=1

  10. Experiment • 1. Evaluate nodes based on their relationships , attributes, and social resources • 2.Identify a set of measurable social resources accessible within online communities • 3.Formalize the notion of accessible and mobilized social resources

  11. 4.Assess the cost associated with reciprocally connecting to an individual • 5.Run experiments to validate our formal models of social capital.

  13. Conclusion We create a quantitative model for characterizing and providing decision support on how to maximize participation within social networks. The result is a mathematical model of social capital that incorporates the mobilization of social resources through purposive actions.
