knowledge representation and logic (first order logic)
First-order logic (FOL) is a formal system used for knowledge representation and reasoning in artificial intelligence and logic-based systems. In FOL, statements are made about objects and their properties using quantifiers, variables, predicates, functions, and logical connectives.
Inference in first-order logic involves making conclusions or deriving new statements based on existing premises using rules of inference. Here are some common methods of inference in FOL:
