Potential applications include support for doctrine development, training, and operations (e.g., Joint EOD Mission Support Center and Decision Support Tools)

Fugitive / Terrorist Description Ontology
Based on FBI website information
Potential applications for “watch list” matching
Description properties include:
Place of birth

Military Knowledge Representation Methodology
Solving complex military problems requires knowledge representations of  tasks, conditions, behaviors, units, and equipment
Our knowledge representation methodology:
Develop a limited but realistic scenario
Build up knowledge representations by combining lightweight, reusable, inter-connectable ontologies (e.g., bibliographic references, military equipment)
Develop sample instance data
Develop prototypes of applications that employ the representations

Lessons Learned
Common repository of instance data (artifacts) needed.
Problems with sites changing content without changing version number and problems with sites changing URIs or dropping out of existence.
Improved tools such as mark-up tools, ontology development tools, validation, complete set of test cases
Problems representing procedural concepts
Needed quality assurance process for test environment (answered it with a methodology we call, “The Mist”)

Quality Assurance Process (Mist)
The Mist is an implementation of a quality assurance methodology.
It consists of a testing environment for newly developed or new versions of both ontologies and artifacts.
It was developed to take advantage of the DAML Validator and the RDF Validator web-based tools.
The solution is a testing directory on DRC DAML website in which Ontologists have read/write privileges. The directory was dubbed the “Mist.”
The Mist also serves as the inbox for publish-ready ontologies and artifacts.
The Mist preserves the integrity of published DAML files, while empowering Ontologists to validate new/revised DAML files via web-based tools.

DRC’s Upcoming Work
Continue EOD Work
Support Joint EOD technology demonstration by providing ontologies, DAML artifacts
Support IPT meetings
Participate in the DAML Experiment
Provide linkage from Afghanistan scenario to UJTL
Represent the national goals and objectives
Provide various supporting ontologies (e.g., weather ontology)

Deliverables
EOD
Requirements analysis documents for EOD knowledge representation for EOD DSS (Word document)
Data model diagrams (IDEF1X or UML tool files)
DAML ontologies and sample artifacts (DAML files)
  DAML Experiment
Artifact tying Afghanistan scenario back to UJTL (DAML file)
Related ontologies, e.g., weather ontology and UJTL conditions (DAML files)
Artifact representing the national goals and objectives  (DAML files)

Metrics
Developed 26 ontologies
Developed 26+ artifacts
Supported  4 military customers (NWDC, CALL, EOD, AMC)
Transitioning 2 programs to other funding sources (EOD, FCG)

BACKUP MATERIALS

What is the Mist?
The Mist is an implementation of a quality assurance methodology.
It consists of a testing environment for newly developed or new versions of both ontologies and artifacts.
It was developed to take advantage of the DAML Validator and the RDF Validator web-based tools.
The web tools require the file under test to have a valid URL.
However, for a variety of reasons, a webmaster should be the only one allowed make changes to website content.
While under test, a DAML file is likely to change too frequently to be officially published by a webmaster.
This conflict created a need for a location wherein an Ontologist can “publish” developing DAML files for testing purposes.

The Mist Solution
The solution is a testing directory on DRC DAML website in which Ontologists have read/write privileges. The directory was dubbed the “Mist.”
One constraint on use of the Mist is that the resulting URI for a DAML file under test, must be virtually identical to the URI it should have once officially published.
Thus the only difference between the a Mist URI and an officially published URI is the inclusion of the .../mist/… directory, i.e.:
http://orlando.drc.com/daml/ontology/Locator/G3/Locator-ont-g3r1.daml
http://orlando.drc.com/daml/mist/ontology/Locator/G3/Locator-ont-g3r1.daml

Publishing from the Mist
The Mist also serves as the inbox for publish-ready ontologies and artifacts.
The Ontologist simply needs to inform the Webmaster that a particular DAML file in the Mist is ready for publication.
The Webmaster can then remove references to the Mist directory from the validated DAML file and move it to its official location.
The Mist preserves the integrity of published DAML files, while empowering Ontologists to validate new/revised DAML files via web-based tools.

Event Chronology Ontology
Potential application for intelligence report representation (event-centric)
Populated sample file with events from 9/11 based on CNN chronology
Populated another sample with FBI chronology of Atta activities prior to attacks

Military Land Platform Ontology
Ontology focused on a taxonomy of equipment types
Ontology is modeled after Distributed Interactive Simulation (DIS) Entity Enumerations document

Slide 22

Foreign Clearance Guide
AFRL conducting research to reduce cost and time required to obtain clearances from foreign governments
Focused on lead times associated with diplomatic (DIP) clearances
Migrated IDEF1X data model to DAML+OIL ontology
Knowledge acquisition at Scott AFB in joint project with BBN

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

DAML Development for UTSS Experiment
Created an Entity DAML ontology with Platform and Munitions (based on DIS Entity Enumeration taxonomy)
Created UTSS-specific DAML ontology tied to Platform ontology (i.e., A64A subclass of A64A class)
Translated UTSS data into DAML artifact / instance file
