Abstract: A prototype expert system for the computer science section (QA75 to QA76.95) of Library of Congress Classification was built using the Mahogany Professional expert system shell. The prototype demonstrates an expert systes application in which the system is enlisted as an intelligent job aid to assist users during the actual performance of shelflisting

Abstract

In an interview with Robert P. Holley, Karen M. Drabenstott provides a history of a professional career that has focused on subject access to information. Since her early work with Pauline Cochrane, she has strongly supported enhanced bibliographic records as a way to improve user access in the online catalog. Her Dewey Decimal Classification Online project showed that the classification offers increased subject retrieval. Her current projects include improved strategies for Web searching and multimedia literacy including subject access.

Abstract

The first studies of online catalog use demonstrated that the problems of too many and too few retrievals plagued the earliest online catalog users. Despite 15 years of system development, implementation, and evaluation, these problems still adversely affect the subject searches of today's online catalog users. In fact, the large-retrievals problem has grown more acute due to the growth of online catalog databases. This paper explores the use of library classifications for consolidating and summarizing high-posted subject searches and for handling subject searches that result in no or too few retrievals. Findings are presented in the form of generalization about retrievals and library classifications, needed improvements to classification terminology, and suggestions for improved functionality to facilitate the display of retrieved titles in online catalogs
