BuzzSkyline writes "The National Science Foundation has announced a new University of Arizona project, which they call the Dark Web, intended to monitor all terrorist activity on the Internet. The project relies on 'advanced techniques such as Web spidering, link analysis, content analysis, authorship analysis, sentiment analysis and multimedia analysis [to] find, catalog and analyze extremist activities online.' The coolest part of the project is a tool called Writeprint, which 'automatically extracts thousands of multilingual, structural, and semantic features to determine who is creating "anonymous" content' with an accuracy of 95%, according to the release."
