This is a NAVAL POSTGRADUATE SCHOOL MONTEREY CA report procured by the Pentagon and made available for public release. It has been reproduced in the best form available to the Pentagon. It is not spiral-bound, but rather assembled with Velobinding in a soft, white linen cover. The Storming Media report number is A218093. The abstract provided by the Pentagon follows: Organizations are policy-driven entities. Policy bases can be very large and complex; these factors are compounded by the dynamic nature of policy evolution. Thus, comprehension of the ramifications of both policy modification and assurance of the consistency, completeness, and correctness of a policy base necessarily requires some level of computer-based support. A policy workbench is an integrated set of computer-based tools for developing, reasoning about, and maintaining policy. A workbench takes as input a computationally equivalent form of policy statements. In this thesis we explore approaches for translating natural-language policy statements into their equivalent computational form with minimal user interaction. We present the architecture of a natural-language input-processing tool (NLIPT), which we designed to augment a policy workbench. NLIPT components consist of an extractor, index-term generator, structural modeler, and logic modeler. We experimented with a prototype of the extractor. The extractor successfully parsed twenty-seven of a sample of ninety-nine of U. S. Department of Defense security policy statements. An additional twenty-one statements were correctly parsed based on the syntactic structure of the input.
