FOL is sufficiently expressive to represent the natural language statements in a concise way. Theoretical computer science developed out of logic, the theory of computation (if this is to be considered a different subject from logic), and some related areas of mathematics. ... Another name of First-Order Logic is ‘Predicate Logic’. 2 What is logic? Proposition and predicate are related. Both systems are known to be consistent, e.g. First-order logic is also known as Predicate logic or First-order predicate logic. The propositional logic is not powerful enough to represent all types of assertions that are used in computer science and mathematics, or to express certain types of relationship between propositions such as equivalence. An answer to the question, "how to represent knowledge", requires an analysis to distinguish between knowledge “how” and knowledge “that”. [] So theoretically minded computer scientists are well informed about logic even when they aren’t logicians. Introduction to Predicate Logic. True; False As such predicate logic includes propositional logic. 1. Propositional logic is an axiomatization of Boolean logic. Logic 2. Example for predicate: “x” is in Europe // x is a variable here > A proposition is a statement that is either true or false. First, we’ll look at it in the propositional case, then in the first-order case. Example for proposition : Germany is in Europe. Facts about Propositional Logic. It is an extension to propositional logic. Knowledge Representation Issues, Predicate Logic, Rules How do we represent what we know ? First-order logic is another way of knowledge representation in artificial intelligence. It will actually take • Knowledge is a general term. The Predicate logic is a symbolized reasoning in which we can divide the sentence into a well-defined subject and predicate." 6.825 Techniques in Artificial Intelligence Resolution Theorem Proving: Propositional Logic • Propositional resolution • Propositional theorem proving •Unification Today we’re going to talk about resolution, which is a proof strategy. "In the propositional logic system of knowledge representation, it is assumed that the word contains object, relations, and functions. Propositional logic is decidable, for example by the method of truth tables: [Truth table -- … Logic and Artificial Intelligence 1.1 The Role of Logic in Artificial Intelligence.
