In generating sentences by means of a transformational grammar, it is necessary to analyze trees, testing for the presence or absence of various structures. This analysis occurs at two stages in the generation process--during insertion of lexical items (more precisely, in testing contextual features), and during the transformation process, when…

A comprehensive system for transformational grammar has been designed and is being implemented on the IBM 360/67 computer. The system deals with the transformational model of syntax, along the lines of Chomsky's "Aspects of the Theory of Syntax." The major innovations include a full and formal description of the syntax of a transformational…

For the two years prior to this report the Computational Linguistics Project in the Computer Science Department at Stanford University was engaged in research leading to computer programs for accepting and manipulating transformational grammars corresponding to a version of the theory based on Chomsky's "Aspects of the Theory of Syntax." These…

The papers in this volume describe computer runs with six different transformational grammars, in each case using the computer system for transformational grammar described in AL 002 220. They are collected as examples which, it is hoped, will encourage other linguistics to use the system. The motivation for the first three projects described was…
