Knowledge representation based on rule + exception strategies has strong cognitive roots and can play an important role in the design and implementation of intelligent information systems, including those motivated by homeland security-related applications. In this framework, you can succinctly describe normal situations or behaviors by easily understandable rules. You can also capture abnormal cases by exceptions to these rules. This rule + exception-based approach has great potential to evolve into a unified multiple-level data description and understanding framework applicable across many security informatics applications.<p>This article is part of a special issue on homeland security.</p>
