The past three years have seen significant interest and progress made in national/international and homeland security research, particularly in the development of methodologies and tools to enable analysts and researchers to advance the state of knowledge by using computer science and information technology in the areas of terrorism research, intelligence analysis, and security-related public policy. We believe that much as for the sciences of "medical informatics" and "bioinformatics," there is a pressing need to develop the science of "intelligence and security informatics" -- the study of the development and use of advanced information technologies, computer science, and algorithms for national/international and homeland security related applications, through an integrated technological, organizational, and policy based approach.

The first and second symposiums on Intelligence and Security Informatics (ISI-2003 and ISI-2004) were held in Tucson, Arizona. These meetings provided a stimulating intellectual forum for discussions among previously disparate communities: academic researchers (in information technologies, computer science, public policy, and social and behavioral studies), local, state, and federal law enforcement and intelligence experts, and information technology industry consultants and practitioners. Proceedings for these two symposiums were published in Springer Lecture Notes in Computer Science (LNCS).

Building on the momentum of these ISI symposiums and with sponsorship by the IEEE, the IEEE International Conference on Intelligence and Security Informatics (IEEE ISI-2005) was held in May 2005 in Atlanta, Georgia. ISI-2005 was co-located with the Sixth Annual National Conference on Digital Government Research (see http://dgrc.org/dgo2005/).

In addition to the established and emerging ISI research topics covered at ISI-2003 and ISI-2004, ISI-2005 included a new track on Terrorism Informatics, which is a new stream of research, using the latest advances in social science methodologies, technologies and tools. This track presented state-of-the-art terrorism informatics research by leading terrorism research experts and institutions.

ISI 2005 also included new and exciting research from the NSF-sponsored Information Technology Research (ITR) projects that focused on national and homeland security applications.

The Proceedings of ISI-2005 have been published in Springer LNCS series.
