Implementation

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 . 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 and are two snapshots of the interface.
