Information, not just data, is key to today�s security challenges. To solve these security challenges requires not only advancing computer science and big data analytics but requires new analysis and decision-making environments that enable reliable, decisions from trustable, understandable information. These environments are successful when they effectively couple human decision making with advanced, guided analytics in human-computer collaborative discourse and decision making (HCCD). Our HCCD approach builds upon visual analytics, traceable information, and human-guided analytics and machine learning and focuses on empowering the decision maker through interactive visual analytic environments where non-digital human expertise and experience can be combined with state-of-the-art and transparent analytical techniques. When we combine this approach with real-world application-driven research, not only does the pace of scientific innovation accelerate, but impactful change occurs. I�ll describe how we have applied these techniques to homeland and community security, resiliency,public safety and disaster management.
