EKCP Analysis Part 1 An Ontology Perspective Ontologies

EKCP Analysis Part 1: An Ontology Perspective

Ontologies Needed • Interesting requirements stem from the representation of – Processes and activities – Actors (capabilities, intentions, . . . ) • Many other ontologies needed (equipment, weapons, etc) -- See IET’s proposal

Core Theories of Processes and Activities Process-model has personnel material equipment. . . duration Process-step needed-for substeps

BW Process Models are Grounded on Core Theories of Process and Activities Process-model isa product BW-process isa isa BW Proliferation Research BW agent BW-agent sub-step needed-for Develop BW-agent isa Develop anthrax sub-step needed-for Produce BW-agent . . .

Domain Specific Activities Will Include Domain Specific Knowledge Develop BW-agent sub-step Acquire Seed Stock Acquire Production Materials needed-for Establish Production Facilities Acquire Equipment needed-for isa bio-safety level source Establish Worker Safety

Domain Specific Activities Will be Linked to Core Component Models (Most connections will be in Production Steps) dispersal mechanism Produce anthrax isa sub-step isa employ wet anthrax Produce wet anthrax sub-step isa Ferment agent (Grow anthrax spore) Dispersion Component employ dry anthrax isa Produce dry anthrax Fermentation Component employ anthrax . . . before Milling before Drying store dry anthrax alternatives before isa before Spray-dry Vacuum. Drum dry Azeotropic distillation store wet anthrax

Need to Relate Alternative Substeps Based on Tradeoffs Acquire seed stock alternatives purchase from research supply house cutivate from nature acquire from biotech program acquire from Sympathetic government steal Need to represent comparison factors and their values for each of the alternatives: Ex: cost= high vs cost=low; duration=4 days vs 5 weeks

Need to Relate Alternative Process Models based on Tradeoffs of Individual Steps Produce anthrax isa Produce dry anthrax Spore size=small &worker safety level=low => Difficulty=high Deliver anthrax . . . isa Deliver dry anthrax Produce wet anthrax Spore size=large &worker safety level=high => Difficulty=low isa Deliver wet anthrax Dispensing=hard & Vulnerable to environme => Inadequate for battlefie Dispensing=easy & Hardier on environment => Adequate for battlefield use

Relating Actors with Tradeoffs in Process Models Non-friendly Gov’t Produce anthrax Intentions isa =>battlefield employment Produce dry anthrax Spore size=small &worker safety level=low => Difficulty=high Deliver anthrax . . . isa Deliver dry anthrax Produce wet anthrax Spore size=large &worker safety level=high => Difficulty=low isa Deliver wet anthrax Dispensing=hard & Vulnerable to environment => Inadequate for battlefield use Dispensing=easy & Hardier on environment => Adequate for battlefield use
