Focus
• 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
• 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
• 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)

DAML Query Demonstration
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
• 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
• 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 (FCG)
• Land mine warfare demonstration

Hot DAML Work
DAML DINING:
• 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

What’s Hot
• 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
Dynamics Research Corporation
What’s Hard
• 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
• DRC is focused on demonstrating semantic web value to military users
• DRC has been developing DAML Military Application Demonstrations– CALL Thesaurus– Military Equipment– Thesauri-assisted search of DAML content– IMO Intelligence Report
• DRC is focusing continued research to support:– Army CALL UAN WKN effort and– Intelink Management Office– Land Mine Warfare doctrine sample
