Finding Potential Terrorists Online

Greetings from the regular Information Retrieval meeting at CSIRO in Canberra, where
Omid Rezvani (ANU) is speaking on "Community detection in large networks". The idea is that you can look at the links between people on-line to identify communities. This is typically used for targeted marketing: if someone in the identified group like a product, the others are likely to as well. Another use for the technology, I suggest, is to find people at risk of being recruited by terrorist groups (which the PM is concerned about). There has been some recent research on this.
