I am also pursuing application of results in these areas to the problem of developing and maintaining large grammars. My doctoral studies were carried out in the Computer and Information Sciences Department at the University Delaware under K. Vijay-Shanker. Copies of my dissertation Studies in the Logic of Trees with Applications to Grammar Formalisms are available from the Univ. This is not yet available electronically, although an abstract is available here. The following preprints and drafts are available here.
Comments are welcome.
Syntactic Structures as Multi-Dimensional Trees. This surveys the work below along with some more recent work. This version is scheduled to appear in an issue of the Journal of Language and Computation including papers from that workshop. Generalized Tree-Adjoining Grammar. A paper presented at the Sixth Meeting on Mathematics of Language.
