Discourse Representation Structures (DRS) is a formal notation within Discourse Representation Theory (DRT), designed to represent the semantics of natural language discourse. It uses box-like structures to capture referents, conditions, and their relationships, enabling dynamic semantic analysis for anaphora and context-sensitive expressions.
