Answer 1

A: Its role is keep updating the knowledge base with changes.

Question 2

Differentiate between forward chaining and backward chaining in the context of reasoning in intelligent information systems.

Answer 2

A: Forward chaining is first evaluate all conditions, then implement action after figuring out the condition.
In contrast, backward chaining is set the goal first, then backtracks to find what action needed to achieve the goal.
