6 6 EOD Scenario/Vignette n Developed specific task list for scenario of providing EOD support to clear mines from Straits of Hormuz and open lanes from Saudi Arabia to the oilfields n References tasks from UJTL instance file (shown on previous slide) n Potential applications include support for doctrine development, training, and operations (e.g., Joint EOD Mission Support Center and Decision Support Tools)

7 7 Fugitive / Terrorist Description Ontology n Based on FBI website information n Potential applications for watch list matching n Description properties include: l Place of birth l FBI caution l Physical description l Languages used

8 8 Light Weight Reusable Ontologies n Locator n Point of contact n Versioning Element Set (VES) n Dublin Core (DC) n Person n Bibliographic information n Thesaurus – ANSI NISO Z39.19

9 9 Military Knowledge Representation Methodology n Solving complex military problems requires knowledge representations of tasks, conditions, behaviors, units, and equipment n Our knowledge representation methodology: l Develop a limited but realistic scenario l Build up knowledge representations by combining lightweight, reusable, inter-connectable ontologies (e.g., bibliographic references, military equipment) l Develop sample instance data l Develop prototypes of applications that employ the representations

10 10 Lessons Learned n Common repository of instance data (artifacts) needed. n Problems with sites changing content without changing version number and problems with sites changing URIs or dropping out of existence. n Improved tools such as mark-up tools, ontology development tools, validation, complete set of test cases n Problems representing procedural concepts n Needed quality assurance process for test environment (answered it with a methodology we call, The Mist)

11 11 Quality Assurance Process (Mist) n The Mist is an implementation of a quality assurance methodology. n It consists of a testing environment for newly developed or new versions of both ontologies and artifacts. n It was developed to take advantage of the DAML Validator and the RDF Validator web-based tools. n The solution is a testing directory on DRC DAML website in which Ontologists have read/write privileges. The directory was dubbed the Mist. n The Mist also serves as the inbox for publish-ready ontologies and artifacts. n The Mist preserves the integrity of published DAML files, while empowering Ontologists to validate new/revised DAML files via web-based tools.

12 12 n Continue EOD Work l Support Joint EOD technology demonstration by providing ontologies, DAML artifacts l Support IPT meetings n Participate in the DAML Experiment l Provide linkage from Afghanistan scenario to UJTL l Represent the national goals and objectives l Provide various supporting ontologies (e.g., weather ontology) DRCs Upcoming Work

13 13 Deliverables n EOD l Requirements analysis documents for EOD knowledge representation for EOD DSS (Word document) l Data model diagrams (IDEF1X or UML tool files) l DAML ontologies and sample artifacts (DAML files) n DAML Experiment l Artifact tying Afghanistan scenario back to UJTL (DAML file) l Related ontologies, e.g., weather ontology and UJTL conditions (DAML files) l Artifact representing the national goals and objectives (DAML files)

14 14 Metrics n Developed 26 ontologies n Developed 26+ artifacts n Supported 4 military customers (NWDC, CALL, EOD, AMC) n Transitioning 2 programs to other funding sources (EOD, FCG)

15 15 Questions?

16 16 BACKUP MATERIALS

17 17 What is the Mist? n The Mist is an implementation of a quality assurance methodology. n It consists of a testing environment for newly developed or new versions of both ontologies and artifacts. n It was developed to take advantage of the DAML Validator and the RDF Validator web-based tools. l The web tools require the file under test to have a valid URL. l However, for a variety of reasons, a webmaster should be the only one allowed make changes to website content. l While under test, a DAML file is likely to change too frequently to be officially published by a webmaster. l This conflict created a need for a location wherein an Ontologist can publish developing DAML files for testing purposes.

18 18 The Mist Solution n The solution is a testing directory on DRC DAML website in which Ontologists have read/write privileges. The directory was dubbed the Mist. l 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. l Thus the only difference between the a Mist URI and an officially published URI is the inclusion of the.../mist/… directory, i.e.: u u

19 19 Publishing from the Mist n The Mist also serves as the inbox for publish-ready ontologies and artifacts. l The Ontologist simply needs to inform the Webmaster that a particular DAML file in the Mist is ready for publication. l The Webmaster can then remove references to the Mist directory from the validated DAML file and move it to its official location. n The Mist preserves the integrity of published DAML files, while empowering Ontologists to validate new/revised DAML files via web-based tools.

20 20 Event Chronology Ontology n Potential application for intelligence report representation (event- centric) n Populated sample file with events from 9/11 based on CNN chronology n Populated another sample with FBI chronology of Atta activities prior to attacks

21 21 Military Land Platform Ontology n Ontology focused on a taxonomy of equipment types n Ontology is modeled after Distributed Interactive Simulation (DIS) Entity Enumerations document

22 22 Ontology Development Commercial Shipping Ontology Define Commercial Ship Classes Subclasses Attributes Instance Data Authoritative Data Source Data Analysis & Decomposition

23 23 Foreign Clearance Guide n AFRL conducting research to reduce cost and time required to obtain clearances from foreign governments n Focused on lead times associated with diplomatic (DIP) clearances n Migrated IDEF1X data model to DAML+OIL ontology n Knowledge acquisition at Scott AFB in joint project with BBN

24 24 Equipment Characteristics and Performance n Equipment descriptions used by simulation applications for accurately representing platforms n Leveraged DRC work for Army Modeling and Simulation Office (AMSO) n Sample artifact developed based on Universal Threat System for Simulators (UTSS) sample data for AH-64A

25 25 DAML Development for UTSS Experiment n Created an Entity DAML ontology with Platform and Munitions (based on DIS Entity Enumeration taxonomy) n Created UTSS-specific DAML ontology tied to Platform ontology (i.e., A64A subclass of A64A class) n Translated UTSS data into DAML artifact / instance file
