Consistent Grammar Development Using Partial-Tree Descriptions for Lexicalized Tree-Adjoining Grammars
TAGs contain a bunch of trees, and maintaining / changing them can be a pain. This paper describes how they basically built a system that generates the tree set, based on a few steps, each of which is parameterized by data: start with subcat frames, then transform them with a set of transforms to get a bigger set of subcat frames, etc.
