WebAnnotated Parse Tree • 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. WebA parse tree is an entity which represents the structure of the derivation of a terminal string from some non-terminal (not necessarily the start symbol). The definition is as in the book. Key features to define are the root ∈ V and yield ∈ Σ* of each tree. For each σ ∈ Σ, there is a tree with root σ and no children; its yield is σ.
