Quantifiers: for all, there exists Predicates: integer, greater, prime, even, equals. Constants: 2 Functions: sum.¡ Z ª , æó Ÿ ¨ Semantics Ÿ ¨ Validity = true in every model and every interpretation. Interpretation = mapping of constants, predicates, functions into objects, relations, and functions.
Delve into Predicate Logic's syntax, semantics, and inference capabilities to represent complex knowledge concepts beyond propositional logic. Learn about objects, terms, predicates, connectives, quantifiers, and formulas within Predicate Logic, offering a rich language for AI.
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. Requires a richer abstraction of the world.

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. It ...
Predicate Logic or FOL Chapter 8 Syntax See text for formal rules. All of propositional + quantifiers, predicates, functions, and constants. Variables can take on values of constants or terms. Term = reference to object Variables not allowed to be predicates.

Predicate Logic Second Term Fourth Year (10 CS) Predicate Calculus In this course, we shall only study First order Logic (FOL) Higher-Order Logic First-Order Logic Introduction to FOL • In propositional calculus, each atomic sentence (P, Q etc.) denotes a proposition of some complexity.
Motivations Propositional logic can only express whole sentences. It doesn’t allow you to access the components within a sentence, e.g., subject, object, adjectives, etc. Predicate logic has that capability.

Preview: we will define a logic (first-order logic) which is expressive enough to say almost anything of interest, and for which there exists a sound and complete inference procedure.
Predicate Logic VALID To capture what makes this form valid we need to notate the subject and predicate of a proposition. All A are B n is A n is B Although Propositional Logic is complete ...
Predicate Logic. From Propositional Logic to Predicate Logic. Last week, we dealt with propositional (or truth-functional) logic: the logic of truth-functional statements. Today, we are going to deal with predicate (or quantificational) logic.
Explore the fundamentals of predicate logic, its symbols, attributes, and practical examples. Learn to translate English sentences into First-Order Logic and build a genealogy knowledge base using predicates and facts.
During the study of discrete mathematics, I found this course very informative and applicable.The main points in these lecture slides are:Predicate Logic, Propositional Function, Universe of Discourse, Universal Quantifier, Existential Quantifier, Quantifier Negation, Negation Rule, Existential Quantification, English Translation, Numerical Value
Propositional and Predicate Logic Propositional Logic The study of statements and their connectivity structure. Predicate Logic The study of individuals and their properties.

The document presents an example of using predicate logic to represent facts and relationships. It includes 8 facts about Marcus and uses predicate logic to prove that Marcus is dead. 2. Resolution is introduced as a technique for automated theorem proving through refutation. It ...
Chapter 2, Predicate Logic. Definitions. Subject / predicate John / went to the store. The sky / is blue. Propositional logic- uses statements Predicate logic or calculus- uses predicates predicates must be applied to a subject in order to be true or false P(x)
Predicate Logic. A Logic is a formal language, with precisely defined syntax and semantics, which supports sound inference. Independent of domain of application. Different logics exist, which allow you to represent different kinds of things, and which allow more or less efficient inference.
