Not Quite There Yet
•The SkyNet funding bill is passed.
•The system goes online on August 4th, 1997.
•Human decisions are removed from strategic
defense.
•SkyNet begins to learn at a geometric rate.
•It becomes self-aware at 2:14am Eastern time,
August 29th
•In a panic, they try to pull the plug.
•And, Skynet fights back

• knowlege -> kie
• Examples
• KnowledgeBase -> Kie
• StatefulKnowledgeSession -> KieSession
• StatelessKnowledgeSession - StatelesKieSession
• Legacy API Adapter JAR
• Most API’s should work with legacy adapter
• KnowledegAgents have not been ported, PKG’s are not
longer the unit of deployment

Justification-based Truth
• Drools 5.x
• Simple logical insertion TMS, like Clips, Jess and
others.
• Drools 6.0
• Contradiction handling with JTMS
• Clean separation of exception logic
• TMS now has pluggable Belief System
• Simple TMS support
• JTMS now possible.

de-couples the logic
Maintains the truth by
automatically retracting
•A rule “logically” inserts an object
•When the rule is no longer true, the object is retracted.
rule "IsChild"
when
$p : Person( age < 16 )
then
logicalInsert( new IsChild( $p ) )

Questions?
• Dave Bowman: All right, HAL; I'll go in
through the emergency airlock.
• HAL: Without your space helmet, Dave,
you're going to find that rather difficult.
• Dave Bowman: HAL, I won't argue with
you anymore! Open the doors!
• HAL: Dave, this conversation can serve
no purpose anymore. Goodbye.
Joshya: Greetings, Professor Falken.
Falken: Hello, Joshua.
Joshya: A strange game. The only winning move is not
to play. How about a nice game of chess?
