List of rules of inference - Wikipedia

WebbWe begin with some simple inference rules that can be applied to sentences with quantiﬁers to obtain sentences without quantiﬁers. These rules lead naturally to the idea that ﬁrst-order inference can be done by converting the knowledge base to propositional logic and using propositional inference, which we already know how to do. WebbA rule-based system (RBS) consists of a knowledge base and an inference engine (Negnevitsky 2002), (Liebowitz, 1998), (Jackson, 1999). The knowledge base is the actual application (control) logic, ウィリスタワーズワトソン

WebbWhat is inference? So far, we’ve considered how to Express statements using propositional and predicate logic. Compute using Boolean (propositional) logic. Show equivalence of diﬀerent ways to express or compute statements. Logic also has methods to infer statements from the ones we know. Equivalence is a small part of this. Webb1.
