WebSentences of this type are “Horn clauses” (A1 ∧L∧ An)⇒B Chaining • Basic inference mechanism (“Modus Ponens”): • Basic idea: Given KB and a symbol S – Forward chaining: Repeatedly apply the inference rule to KB until we get to S – Backward chaining: Start from S and find implications whose conclusions are S Web16 mrt. 2024 · TS_logout_01.
