Roles In Networks


Published on

This short set of slides summarizes the characteristics of people who play specific roles in networks. In a social network analysis, people in these roles can be discovered by running mathematical algorithms through the social graphs. But you don't need to be an algorithm to spot some of these people in your networks!

Roles In Networks

  1. 1.<br />Network Roles<br />Produced for The Community Roundtable from an upcoming on-line self-paced course, Introduction to Social Network Analysis<br />-- Patti Anklam, Net Work<br />
  2. 2. Roles<br /><br />2<br />
  3. 3. Roles in Networks<br />
  4. 4. A View of the Roles: Broadcasters*<br />B, C, and I share (broadcast) information outside their groups<br />*aka Representatives<br />
  5. 5. A View of the Roles: Connector<br />C is connecting (is a liaison to) two other groups<br />
  6. 6. A View of the Roles: Gatekeepers<br />C and E control the flow of information into their groups<br />
  7. 7. A View of the Roles: Coordinators<br />D, E, and J move information around in their groups<br />
  8. 8. A View of the Roles: Peripheral Specialists<br />Nodes that have very few connections to any group<br />
  9. 9. Structural Holes<br />A unique and potentially powerful position<br /><ul><li>A structural hole exists when a single node connects two groups
  10. 10. These are potentially very powerful positions
  11. 11. In many cases, the structural hole’s ties outside its own network may be weak ties</li></li></ul><li>Lurkers<br />May be more important than you think<br /><ul><li>Weakly connected to the network
  12. 12. Usually on the periphery
  13. 13. May infrequent play the role of peripheral specialist
  14. 14. Absorb more than they share
  15. 15. But may move information to other networks</li>
