beled E, with children corresponding to the body of this production, the synthesized q,ttribute val at N is computed using the values of val at the two children, labeled E and T. Thus, a portion of the dependency g�aph for every parse tree in which this production is used looks like Fig. 5.6. As a convention, we shall show the parse tree edges as dotted lines, while the edges of the dependency graph are solid. 0 E val . . . . . . / . . . . . ' . . ' . " . . � . . .
