F=favour D=be a dog P=be a park (∀x) (Ǝy) Dx & Py > Fx,y. H=hire M=be a manager E=be an employee (Ǝx) (∀y) Mx & Ey >Hx,y . My attempt is: All dogs favor to be at least in one park. There is at least one manager who hires all employees.
Example: What does (P(a)∨Q(a,b))mean? The symbols P,Q,a, and bdo not have intrinsic meanings.
Semantics for Predicate Logic: Part I Spring 2004 1 Interpretations A sentence of a formal language (e.g., the propositional calculus, or the predicate calculus) is neither true nor false.

In mathematical logic, predicate functor logic (PFL) is one of several ways to express first-order logic (also known as predicate logic) by purely algebraic means, i.e., without quantified variables. PFL employs a small number of algebraic devices called predicate functors (or predicate modifiers) that operate on terms to yield terms. PFL is mostly the invention of the logician and philosopher Willard Quine.
The are formed by the criteria relating to | Find, read search and problem-solving; constraint solving, deduction, logic, and Logic: Predicate logic, knowledge representation and semantic technologies, NLP previous semantic accounts of polarity phenomena, primarily Ladusaw (1979, Within propositional logic, the two parts of a conditional clause are commonly re.
Otherwise, the formation rules remain as before,
Definition: A formula A or a term t is closed if it contains no free occurrence of a variable.

Variable symbols: x,y,z. Function symbols: f(1),g(2). Predicate symbols: P(1),Q(2). Terms without variables: a, f(a). Formulas without variables: P(a), Q(a,b), (¬P(a)), (P(a)∨Q(a,b)).
Its basic elements (entities) correspond to things in the world and their properties (predicates). Predicate Logic is an extension of Propositional Logic not a replacement.

Sentences in first-order predicate logic can be usefully interpreted as programs. In this paper the operational and fixpoint semantics of predicate logic programs
KAIST moonzoo@cs.kaist.ac.kr. The atomic wffs are then simply those consisting of a predicate variable followed by a single individual variable. Otherwise, the formation rules remain as before, Definition: A formula A or a term t is closed if it contains no free occurrence of a variable. A closed formula is called a sentence. Semantics of Predicate Calculus.
The function assigning semantic values is denoted by '[[ ]]'. In the standard semantics of predicate logic, the interpretation of a formula is a set of assignments, viz.,
