The backward chaining algorithm can answer questions in Horn clause knowledge bases.
It works by taking the goal and checking to see if it unifies directly with a sentence in the database.
If so, it returns the substitution list that makes the query equal the known sentence.
Otherwise, backward chaining finds all the implications whose conclusions unify with the query and then tries to establish their premises.
Consider a knowledge base that says it is illegal to sell weapons to hostile nations. It also says that Colonel West sold all of country Nono's missiles to it. And missiles are weapons.
American(x) AND Weapon(y) AND Nation(z) AND Hostile(z)
AND Sells(x,y,z) => Criminal(x)
Owns(Nono, x) AND Missile(x) => Sells(West,Nono,x)
Missile(x) => Weapon(x)
Enemy(x,America) => Hostile(x)
We add to it the following facts:
American(West)
Nation(Nono)
Enemy(Nono, America)
Missile(M1)
We want to solve the crime: Is West a criminal?
disini maksd nya disuruh gambarkan ketentuan" di atas, dan berdasarkan itu kita bsa membuktikan kalau yang benar adalah :
criminal > sells > owns , missile
