Predicting a predator: Purdue AI tool identifies online deviants before they act

WEST LAFAYETTE, Ind. — Technology provides child predators with a means to troll for targets online, but a pair of Purdue University researchers have harnessed the power of artificial intelligence to help catch sex offenders before they make physical contact with the children.

With statistics suggesting that up to one in 25 children are sexually solicited online, the technology has the potential to make an impact.

Called the Chat Analysis Triage Tool (CATT), it uses natural language processing techniques to analyze conversations between minors and child predators and determine which adults are most likely to be “contact offenders,” that is, people who actually seek to meet children in person.

Kathryn Seigfried-Spellar, assistant professor of computer and information technology, and Julia Rayz, associate professor of computer and information technology, will give a joint talk about their “digital forensics tool” at Dawn or Doom ’18, Purdue’s annual conference on the risks and rewards of emerging technologies. Dawn or Doom will be held on Purdue’s West Lafayette campus Nov. 5-6. The conference, now in its fifth year, is free and open to the public. Visit the Dawn or Doom website for more information and a full list of speakers.

Dawn or Doom is aligned with Purdue’s Giant Leaps Sesquicentennial Campaign and is part of the Ideas Festival theme, Giant Leaps in Artificial Intelligence, Algorithms, and Automation: Balancing Humanity and Technology. The Ideas Festival is the centerpiece of the campaign and connects world-renowned speakers and Purdue expertise in a conversation on the most critical problems and opportunities facing the world. ..Read More..
