Social-networking analysis

Here are some links that came up during our discussion of social-networking analysis last Wednesday:

• "They Run Richmond." An interactive graphic tracing powerful people and institutions in Richmond, Va.
• "Uncloaking Terrorist Networks." A post-9/11 analysis by Valdis E. Krebs, published in the online journal First Monday.
• "They Rule." Do-it-yourself social networking. An experimental site based on 2004 data.

Investigative Reporters and Editors offers a section of social-networking analysis resources.
