INNOVATIVE SOLUTIONS THROUGH PEOPLE, PROCESSES, AND TECHNOLOGY

Dynamics Research Corporation


• Primarily DoD information technology services company

• Background in developing XML standards for U.S. Army applications

• DRC DAML team focused on military applications

• “Early Adopters” of DAML technology• Architecting DAML solutions to satisfy warfighter

and other users’ requirements



Ontology Development Philosophy

• Building block approach• Focused on developing small, reusable, inter-

connectable ontologies (e.g., bibliographic references, military equipment)



DAML Military Ontologies

• Military land platform taxonomy/ontology• Equipment Characteristics and Performance

(C&P)• Event chronology ontology• Fugitive/terrorist description ontology• Military task list ontology• Explosive Ordnance Disposal (EOD)

scenario/vignette



Military Land Platform Ontology

• Army Military Equipment Characteristic & Performance (C&P) Ontology

• Ontology focused on a taxonomy of equipment types

• Ontology is modeled after Distributed Interactive Simulation (DIS) Entity Enumerations document



Equipment Characteristics and Performance

• Equipment descriptions used by simulation applications for accurately representing platforms

• Leveraged DRC work for Army Modeling and Simulation Office (AMSO)

• Sample artifact developed based on Universal Threat System for Simulators (UTSS) sample data for AH-64A



Chronology Ontology

• Potential application for intelligence report representation (event-centric)

• Populated sample file with events from 9/11based on CNN chronology

• Populated another sample with FBI chronology of Atta activities prior to attacks



Fugitive / Terrorist Description Ontology

• Based on FBI website information• Potential applications for “watch list” matching• Description properties include:

– Place of birth

– FBI caution

– Physical description

– Languages used



Military Task List Ontology

• Supports representation of military task lists (e.g., UJTL, UNTL, AUTL)

• Populating sample instance file with Universal Joint Task List (UJTL)



EOD Scenario/Vignette

• Developed specific task list for scenario of providing EOD support to clear mines from Straits of Hormuz and open lanes from Saudi Arabia to the oilfields.

• References tasks from UJTL instance file• Potential applications include support for doctrine

development, training, and operations.



Foreign Clearance Guide

• AFRL conducting research to reduce cost and time required to obtain clearances from foreign governments

• Focusing on lead times associated with diplomatic (DIP) clearances

• Migrated IDEF1X data model to DAML+OIL ontology

• Working with DRC personnel at Scott AFB and BBN



Summary

• DRC has been developing DAML Military Application Ontologies– Military land platform taxonomy/ontology

– Event chronology ontology

– Fugitive/Terrorist description ontology

– Military Task List ontology

• DRC is focusing continued research to support:– EOD (Naval Warfare Doctrine Command)

– Foreign Clearance Guide (AFRL)
