A Tool for Displaying Syntactic Trees.
Morgan, Jerry L.
A computer program for drawing syntactic phrase markers as trees is described. The program was developed for use on Texas Instruments Explorer Lisp machines. The tree is drawn by recursive descent, left to right. The tree-drawing function takes two arguments: (1) an atom constituting the tree, and (2) a font specification to be used in drawing the tree. The tree argument must be an atom that constitutes the root node of the tree to be displayed. For interfacing to parsers or other tools that represent parses as lists, a function can be used to convert a list representation of a parse to the linked-atom representation used in this program. Two convenient elaborations are in development: a mouse handler for the tree window and a feature display. Appended materials include some sample trees from the program and the program's source listing. (MSE)
