Meaning Representation
摘要
Before diving into Semantic Analysis, this chapter examines meaning representation, a crucial component of NLP that precedes discussions on semantic and pragmatic analysis. It explores four major meaning representation techniques: first-order predicate calculus (FOPC), semantic nets, conceptual dependency diagrams (CDD), and frame-based representation. Following this, the chapter introduces the concept of canonical form and explores Fillmore’s Theory of Universal Cases. It concludes with an in-depth discussion of predicate logic and inference using FOPC, supported by live examples for practical understanding.
