Estimating user interaction strength in online networks
Online networks like Facebook and BitTorrent are based on user interactions such as wall posts and content exchange. In such systems, user relationships can be used to enhance security and promote cooperation, but in order to be meaningful, these relationships should be based on user interaction strength instead of “binary” friendships.
