Chaining Steps for Logical Inference
Discover the process of backward chaining in logical inference. Start with a goal sentence and work backward to find supporting rules, forming sub-goals until all statements are proven true. Explore the steps involved, from inferring facts to extracting predicates and ultimately reaching the desired conclusion.

Presentation Transcript
Backward Chaining Start with goal sentence; search for rules that support goals, adding new sub-goals until match with KB facts or no further inference can be made.
Backward Chaining - Steps Step 1: Take the goal fact. And from the goal fact, we will infer other facts, and at last, we will prove those facts true. Goal: West is Criminal
Backward Chaining - Steps Step 2: we will infer other facts form goal fact which satisfies the rules.
Backward Chaining - Steps Step 3: we will infer other facts form goal fact which satisfies the rules.
Backward Chaining - Steps Step 4: extract more facts from predicates.
Backward Chaining - Steps Step 5: infer the last fact (Enemy and Hostile). Hence, all statements are proved true.
