COMPILER DESIGN

Detailed explanation-1: -AN ANNOTATED PARSE TREE. is a parse tree showing the values of the attributes at each node. The process of computing the attribute values at the nodes is called annotating or decorating the parse tree. stand respectively for an integer number and the newline character.

Detailed explanation-2: -Semantic analysis is the task of ensuring that the declarations and statements of a program are semantically correct, i.e, that their meaning is clear and consistent with the way in which control structures and data types are supposed to be used.

Detailed explanation-3: -A parse tree showing the values of attributes at each node is called an Annotated parse tree. The process of computing the attributes values at the nodes is called annotating (or decorating) of the parse tree. Of course, the order of these computations depends on the dependency graph induced by the semantic rules.

Detailed explanation-4: -Tree-Based Semantic Parsing. Page 1. Introduction. Semantic parsing is the process of mapping natural language sentences to formal meaning representations. Semantic parsing techniques can be performed on various natural languages as well as task-specific representations of meaning.
