Can a computer observe online behavior and spot when someone becomes radicalized?  Researchers at Lancaster U. in the UK think they can.  They looked at 100 million tweets across 100K accounts. The research shows that when users begin either sharing tweets from known pro-ISIS accounts, or using extremist language they quickly display a large change in the language they use, tweeting new words and terms, and indicating a clear shift in online behavior.  http://www.lancaster.ac.uk/
