Algorithm: Resolution Proof
Reducing first-order inference to propositional inference. • Unification. • Generalized Modus Ponens. • Forward chaining. • Backward chaining. • Resolution ...
For example, P(a) v Q(a) is a sentence in FOL but is not a Horn clause.
Example: set of blocks {a, b, c, d, e}. ▫
If you are looking at real-world examples where unification is used and useful, take a look at Unification-based grammars which are used in ...
