GREAT: Graph-based Rapid Extraction and Analysis Tool

GREAT, Graph-based Extraction and Analytical Tool will enable teams of subject matter experts (SMEs) to author knowledge bases directly and easily without knowledge engineers serving as intermediaries. 21st Century Technologies and BBN Technologies shalldemonstrate rapid knowledge formation of complex problem solving patterns and concepts using graph pattern matching technology to increase the speed, agility, and precision of military information systems. Leveraging from 21st Century Technologies TMODS(Terrorist Modus Operandi Detection System) developed under the DARPA EELD program and from BBN's experience in Active Templates and HPKB, analysts can rapidly build complex queries represented as a graph. These graphs are then matched using the graphpattern matching capability of TMODs to automatically detect threat situations. 21st Century Technologies is a team member of the Darpa EELD and Ultra*Log efforts and the ARDA NIMD effort; BBN is a team member of the Darpa HPKB. CoABS, and Active Templateprograms. These two firms can leverage the full capabilities of these combined programs to support development in this effort. benefits include applications to computer security and homeland defense.
