VANCOUVER — Deep within the recesses of the Internet, extremists discuss and plot terrorist acts. But new mathematical tools that combine web crawling techniques, sophisticated algorithms and human expertise are gaining access to this “dark side” of the Web and may help predict and prevent violence.

Researchers engaged in the “Dark Web Project,” a program started partly in response to the 9/11 terrorist attacks, have developed methods for tracking the spread of dangerous ideas through certa...
