NEMESIS: NEtwork Modeling Environment for Structural Intervention Strategies

摘要

NEtwork Modeling Environment for Structural Intervention Strategies (NEMESIS) is a collaboration and integration environment for state-of-the-art network organizational analysis tools. It provides a mechanism for versioning of collaborative artifacts such as models and reports that is coordinated with analysts' workflow (in the form of local task lists), for maximum convenience and minimum obtrusiveness. The NEMESIS integration architecture is bus-oriented and is centered around an XML Schema based language named Organizational Description Language (ODL), which provides a basis for tools to communicate but also provides a means to accommodate the unique data representation needs of specific tools. One network analytical tool, Adaptive Safety and Monitoring (ASAM). matches transactions against a pattern library and manages the uncertainties of the association. ASAM was extended in the second year of NEMESIS to include multiple model tracking, multiple hypothesis testing, and feature-aided tracking. The result was evaluated by SMEs, and their feedback was incorporated. Another tool, Organizational Risk Analysis (ORA), uses an extended dynamic social network representation to determine organizational strengths and vulnerabilities. ORA was evaluated by SMEs, and their feedback was incorporated. A TIE with Cycorp allowed knowledge from their Terrorism Knowledge Base to be translated to ODL so that the NEMESIS integration environment could feed the result to ORA. The efforts of the second year built on the positive foundation of the first year, along the path of fuller system development and measurement in subsequent years.
