EKCP Analysis Part 1: An Ontology Perspective
2
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
3
Core Theories of Processes and Activities
Process-model has personnel Process-step material equipment . . . duration substeps needed-for
4
BW Process Models are Grounded on Core Theories of Process and Activities
isa product BW-process BW-agent isa isa isa isa BW Proliferation sub-step sub-step sub-step Research BW agent Develop BW-agent Produce BW-agent . . . needed-for needed-for Develop anthrax isa
5
Domain Specific Activities Will Include Domain Specific Knowledge
Develop BW-agent sub-step Acquire Seed Stock Acquire Production Materials Establish Production Facilities Acquire Equipment Establish Worker Safety needed-for needed-for isa bio-safety level source
6
Domain Specific Activities Will be Linked to Core Component Models (Most connections will be in Production Steps) dispersal mechanism Produce anthrax . . . employ anthrax isa isa employ dry anthrax employ wet anthrax isa isa Produce dry anthrax Produce wet anthrax Fermentation Component sub-step sub-step sub-step sub-step isa sub-step Ferment agent (Grow anthrax spore) before Milling Drying store dry anthrax before before before alternatives store wet anthrax Dispersion Component isa Azeotropic distillation Spray-dry Vacuum- Drum dry
7
Need to Relate Alternative Substeps Based on Tradeoffs
Acquire seed stock alternatives purchase from research supply house cutivate from nature acquire from Sympathetic government steal acquire from biotech program Need to represent comparison factors and their values for each of the alternatives: Ex: cost= high vs cost=low; duration=4days vs 5weeks
8
Need to Relate Alternative Process Models based on Tradeoffs of Individual Steps
Produce anthrax . . . Deliver anthrax isa isa Deliver dry anthrax Deliver wet anthrax isa isa Dispensing=hard & Vulnerable to environment => Inadequate for battlefield use Produce dry anthrax Produce wet anthrax Spore size=small &worker safety level=low => Difficulty=high Spore size=large &worker safety level=high => Difficulty=low Dispensing=easy & Hardier on environment => Adequate for battlefield use
9
Relating Actors with Tradeoffs in Process Models
Produce anthrax . . . Deliver anthrax Non-friendly Gov’t isa isa Deliver dry anthrax Deliver wet anthrax Intentions =>battlefield employment isa isa Dispensing=hard & Vulnerable to environment => Inadequate for battlefield use Produce dry anthrax Produce wet anthrax Spore size=small &worker safety level=low => Difficulty=high Spore size=large &worker safety level=high => Difficulty=low Dispensing=easy & Hardier on environment => Adequate for battlefield use
