Focus
Dynamics Research Corporation
• Military Applications
– DAML+OIL Ontology development from related DoD database
schemas and implicit ontologies
– Content conversion into DAML+OIL instance data
– Demonstrations of DAML+OIL applications to show “value add”
of semantic web technologies to military users
• Development of “HOT DAML” site that helps people
understand some of the benefits of the semantic web

DAML Military Applications
Dynamics Research Corporation
• U.S. Army Center for Army Lessons Learned (CALL)
Thesaurus ontology and markup
• Military equipment description ontology and markup
• Thesaurus assisted search query for equipment descriptions
• Intelink Management Office Sample HUMINT
Intelligence Report ontology and markup
• Military task list ontology (e.g., UJTL)
• Glossary ontology (extends thesauri ontology)

Military Equipment Ontology
Dynamics Research Corporation
• Army Military Equipment Characteristic & Performance
(C&P) Ontology
• Provides framework to compose Army equipment from the
System Unit to individual component (i.e., radio) level
• Ontology is modeled after data model used by WARSIM
and that housed by the FDB (Functional Description of the
Battlespace)
INNOVATIVE SOLUTIONS THROUGH PEOPLE, PROCESSES, AND TECHNOLOGY
DAML Query Demonstration
Dynamics Research Corporation
Semantic web DAML demonstration
• Uses Call Thesaurus and Military Equipment C&P
ontologies and data to demonstrate the potential of the
semantic web
Demonstration is composed of:
• Thesaurus Lookup Term
• Military Equipment Lookup
• Complex query involving “joining” ontologies by using
thesaurus lookup results to find military equipment terms

Sample Intelligence Report Exercise
Dynamics Research Corporation
• Force protection sample force protection intelligence
report provided by IMO at last DAML PI meeting
• Intent was to help explain complexities of representing
intelligence information using DAML
• DRC developed sample ontology and instance data from
the IMO-provided sample
• Results of exercise and a proposed domain-specific
markup tool are documented in a white paper for IMO

Focus of Upcoming Efforts
Dynamics Research Corporation
• U.S. Army CALL University After Next (UAN) Warrior
Knowledge Network (WKN) Human Intelligence
(HUMINT) Knowledge Management
• DIA’s Intelink Management Office (IMO)
• USAF’s Air Mobility Command Foreign Clearance Guide

Hot DAML Work
Dynamics Research Corporation
• Intended to demonstrate practical uses of semantic web
technology in simple to understand domain
• Example application code shows “semantic join” of hotel
postal code from an itinerary file with postal code of stored
restaurants
DAML DINING:
INNOVATIVE SOLUTIONS THROUGH PEOPLE, PROCESSES, AND TECHNOLOGY
What’s Hot
Dynamics Research Corporation
• Military customer-driven ontologies, artifacts, and
application samples being developed
• XML-based technologies (e.g., XSLT) being leveraged to
manipulate DAML
• Beginning to evangelize DoD community through
presentations and simple demonstrations
INNOVATIVE SOLUTIONS THROUGH PEOPLE, PROCESSES, AND TECHNOLOGY
What’s Hard
Dynamics Research Corporation
• Reusing existing ontologies
• Performing “semantic joins”
• Developing applications without sufficient DAML-specific
tools
• Learning curve for developers (need more samples and
training materials)
• Demonstrating semantic web benefits with real
applications
• Collaboration with identified application partners

Summary
Dynamics Research Corporation
• DRC is focused on demonstrating semantic web
value to military users
• DRC has been developing DAML Military
Application Demonstrations
