1 Dynamics Research Corporation Semantic Web Military Applications Lee Lacy (407) x104 DAML PI Meeting, Nashua, NH July 18-20, 2001

2 INNOVATIVE SOLUTIONS THROUGH PEOPLE, PROCESSES, AND TECHNOLOGY Dynamics Research Corporation Agenda Focus DAML Military Application Demonstrations Live Demonstration of Military Equipment Query Upcoming Efforts Summary

3 INNOVATIVE SOLUTIONS THROUGH PEOPLE, PROCESSES, AND TECHNOLOGY Dynamics Research Corporation 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

4 INNOVATIVE SOLUTIONS THROUGH PEOPLE, PROCESSES, AND TECHNOLOGY Dynamics Research Corporation 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 INNOVATIVE SOLUTIONS THROUGH PEOPLE, PROCESSES, AND TECHNOLOGY Dynamics Research Corporation CALL Thesaurus Ontology Term BT NT CALL Term name descriptorFor RT entry TermFor preferred TermFor ACK AF USE UF domain subClassOf inverseOf subPropertyOf range & domain Legand

6 INNOVATIVE SOLUTIONS THROUGH PEOPLE, PROCESSES, AND TECHNOLOGY Dynamics Research Corporation 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)

7 INNOVATIVE SOLUTIONS THROUGH PEOPLE, PROCESSES, AND TECHNOLOGY Dynamics Research Corporation 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 URL:

8 INNOVATIVE SOLUTIONS THROUGH PEOPLE, PROCESSES, AND TECHNOLOGY Dynamics Research Corporation DAML Query Demonstration

9 INNOVATIVE SOLUTIONS THROUGH PEOPLE, PROCESSES, AND TECHNOLOGY Dynamics Research Corporation 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

11 Dynamics Research Corporation 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 INNOVATIVE SOLUTIONS THROUGH PEOPLE, PROCESSES, AND TECHNOLOGY Dynamics Research Corporation Hot DAML Work DAML DINING: 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

13 INNOVATIVE SOLUTIONS THROUGH PEOPLE, PROCESSES, AND TECHNOLOGY Dynamics Research Corporation 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 INNOVATIVE SOLUTIONS THROUGH PEOPLE, PROCESSES, AND TECHNOLOGY Dynamics Research Corporation 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 INNOVATIVE SOLUTIONS THROUGH PEOPLE, PROCESSES, AND TECHNOLOGY Dynamics Research Corporation 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
