Abstract We describe a system being developed for the transformational analysis of complex English sentences. The system is designed to be able to serve as a “front-end” for a variety of applications, such as question-answering, information retrieval, and command systems. It is a two-stage system, with the first stage being the Linguistic String Parser previously developed at New York University. The structure of the system and its relation to contemporary transformational parsers are considered. Several transformations, including those for nominalization, are described in detail, and several sentence analyses produced by the program are presented.
