DAML PI Meeting, Nashua, NH July 18-20, 2001
2
Agenda

• Focus
• DAML Military Application Demonstrations
• Live Demonstration of Military Equipment Query
• Upcoming Efforts
• Summary

3
Focus

• Military Applications
• DAMLOIL Ontology development from related DoD
  database schemas and implicit ontologies
• Content conversion into DAMLOIL instance data
• Demonstrations of DAMLOIL 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

4
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)

5
CALL Thesaurus Ontology
Term
6
Military Equipment Ontology

• Army Military Equipment Characteristic
  Performance (CP) 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)

7
DAML Query Demonstration

• Semantic web DAML demonstration
• Uses Call Thesaurus and Military Equipment CP
  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
• URL http//orl01.drc.com/daml/demo/

DAML Query Demonstration

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

Intelligence Report Ontology
INNOVATIVE SOLUTIONS THROUGH PEOPLE, PROCESSES,
AND TECHNOLOGY
11
Focus of Upcoming Efforts

• U.S. Army CALL University After Next (UAN)
  Warrior Knowledge Network (WKN) Human
  Intelligence (HUMINT) Knowledge Management
• DIAs Intelink Management Office (IMO)
• USAFs Air Mobility Command Foreign Clearance
  Guide (FCG)
• Land mine warfare demonstration

12
Hot DAML Work

• 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

13
Whats 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

14
Whats 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

15
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
