The input of our system is the description of the language, which includes the subcategorization frame list, LRR list, subcategorization block list and transformation lists. The output is a list of trees generated automatically by the system, as shown in Figure D.6. The tree generation module is written in Prolog, and the rest part is in C. We also have a graphic interface to input the language description. Figure D.7 and D.8 are two snapshots of the interface.
