Title
¬An expert system approach to online catalog subject searching
Source
Information processing and management. 30(1994) no.2, S.223-238
Year
1994
Abstract
The various ways of improving the online catalog for subject searching are reviewed. The paper then discusses the expert system approach to developing a subject search front-end. It is suggested that an effective expert front-end can be developed by focusing on search strategies. A design for a rule-based expert system front-end is described. Possible search strategies and selection rules are illustrated. The inference structure of the system is based on Clancey's model of heuristic classification
