New mathematical tools that combine Web-crawling techniques, sophisticated algorithms and human expertise are gaining access to the "dark side" of the Web, where extremists discuss and plot terrorist acts. The Dark Web Project, started partly in response to the 9/11 attacks, has developed ways to track the spread of dangerous ideas through rogue and jihadi Web forums. With a mathematical model known as SIR, also used by epidemiologists to describe disease transmission, researchers have determined that the infection rate for becoming a suicide bomber is 2 in 10,000, Hsinchun Chen of the University of Arizona reported February 18.
