Coding online communication to detect sexual predators

Some of you may remember that I’m headed to Iowa State University in about a month. I ran across a story on its news service last week about Chad Harms, a professor in the Greenlee School of Journalism and Communication, who has been doing research on how online sexual predators ‘groom’ their child victims and how their online communication can be coded to detect predatory behavior. Read the story and follow the links. This looks like interesting stuff, particularly if you could automate the coding so that it could be done by computer software.
