Mathematical Model Analyzes Facebook Networks to Prioritize Who Should Receive Vaccinations
People who are "bridges" among different social groups appear as good vaccination bets
The mathematical model focused on the fact that just a few individuals often form the links between different social groups. It also made use of data that came from back in 2005, when Facebook was only open to college students.
The relationships and interactions on five university campuses provided a useful starting scenario for the model to recognize clusters of people and predict bridges between them.
"When a new virus starts spreading, neither the time nor the necessary doses of vaccine to immunize everyone is available," said Marcel Salathe, a postdoc biology researcher at Stanford University. So you'd want a strategy that allows you to protect a population as much as possible given the limited resources that you have."
More details on the Stanford work appear in the April 8 issue of the PLoS Computational Biology.
Scientists have made growing use of social networking data that contains once-personal info. HP Labs researchers recently announced that they used Twitter data to of the latest Hollywood films. And the Pentagon's DARPA challenged people to sift through the disinformation available on social networks such as Twitter and hunt down the physical location of located around the U.S.
