Inference and Entailment • Many different logics can be defined: • Predicate Logics • First-order Logics • Description Logics (subset of FOL) • Etc. • Entailment: • Can be determined via semantics (co-NP-complete) • Inference • Procedure to determine entailment
First Order Predicate Logic Limitation of Propositional Logic. First Order Predicate Logic Limitation of Propositional Logic The facts: “peter is a man”, “paul is a man”, “john is a man” can be symbolized by P, Q and R, respectively in PL. But we would not be able to draw any conclusions about similarities between P, Q and R.

−In artificial intelligence (AI), main focus is to store knowledge so that programs can process it and achieve human intelligence. There are different ways of representing knowledge e.g. −predicate logic, −semantic networks, −extended semantic net, −frames, −conceptual dependency etc.
• Negation of predicate formulas • Text book chapter 1.3 2 Weakness in propositional logic Recall the weakness outlined for propositional logic: • The logic fails to model the internal structure of propositions. • e.g. Every positive number is greater than zero. • Let’s define a logic that models some of this internal structure.

Predicate Calculus (述語推算) zPredicate Calculus extends the syntax of propositional calculus with predicates and quantifiers: P(X) – P is a predicate. zFirst Order Predicate Calculus (FOPC) allows predicates to apply to objects or terms, but not functions or predicates.
The following are the topics in this presentation Prepositional Logic (PL) and First-order Predicate Logic (FOPL) is used for knowledge representation in artificial intelligence (AI). There are also sub-topics in this presentation like logical connective, atomic sentence, complex sentence, and quantifiers.
14864_5_Predicate logic (Lecture 19-22).ppt - Free download as Powerpoint Presentation (.ppt), PDF File (.pdf), Text File (.txt) or view presentation slides online. This document discusses representing knowledge using predicate logic. It introduces predicate logic as an extension of propositional logic that allows representing properties and relationships between objects using predicates.
