Abstract

We address the problem of tracking a group of agents based on their communications over a network when the network devices used for communication (e.g., phones for telephony, IP addresses for the Internet) change continually. We present a system design and describe our work on its key modules. Our methods are based on detecting frequent patterns in graphs and on visual exploration of large amounts of raw and processed data using a zooming interface.
