Here's another reason to get off that antisocial kick and get with the networking.

The Air Force is developing a data-mining technology meant to root out disaffected insiders based on their e-mail activity--or lack thereof, according to an article in this month's International Journal of Security and Networks.

The technology, based on something called Probabilistic Latent Semantic Indexing (PDF), scours an organization's e-mail traffic and constructs a graph of social network interactions illustrating employee activity. If a worker suddenly stops socializing online, abruptly shifts alliances within the organization, or starts developing an unhealthy interest in "sensitive topics," the system detects it and alerts investigators.
