The BBN Knowledge Acquisition Project: Phase 2
Abstract
This document presents the final report on Phase Two of the BBN knowledge Acquisition Project. It includes an overview of the project, and a review of the KREME, the Knowledge Representation Editing and Modeling Environment developed during the project. KREME was designed to ease the problems involved in the development and maintenance of large knowledge based systems, to support experiments with knowledge acquisition and knowledge engineering techniques, and to provide a useable system for knowledge acquisition for knowledge based systems. During Phase One of the project KREME editors for Frames, Rules and Procedures were developed. Techniques were also developed for consistency maintenance and macro editing of knowledge bases. During Phase Two, refinements were made to the KREME Frame Language and Editor, with an eye toward real-world applications and portability. These refinements included extentions of the frame language and the frame classifier to allow for the expression of a wider variety of constraints on the represented knowledge. A new interface was also designed and implementing enabling more flexible editing and browsing of knowledge bases. KREME was also converted to run in Common Lisp using the CLOS object system, in preparation for its use on other hardware platforms. Phase Two also included experiments in the use of KREME tools in the COMMON LISP environment,in conjunction with a tool for document indexing and retrieval.
