Propositional Logic in AI: Syntax and Semantics

Propositional logic builds expressions from propositions and connectives such as NOT, AND, and OR. This video covers the syntax, the semantics, and why that system still appears in artificial intelligence. Syntax is how a formula is written. Semantics is how it gets a truth value. Applications can include simple rule-based reasoning next to newer models. It is an introduction, not a forecast of logical AI. Topics covered: Propositions and connectives Syntax of a formula Semantics and truth values A basic use in AI What this video does not prove about modern systems This video is general education.
