Cost Effectiveness of On-Line Retrieval System.
King, Donald W.; Neel, Peggy W.
A recently developed cost-effectiveness model for on-line retrieval systems is discussed through use of an example utilizing performance results collected from several independent sources and cost data derived for a recently completed study for the American Psychological Association. One of the primary attributes of the model rests in its great flexibility in that various combinations of alternative systems and subsystems are open to comparison. Some of the systems which have been addressed include batch processing, on-line abstract and the subsystems include various levels of recall, several types of screening, and different user-system interfaces. The example chosen for discussion in this paper presents a cost-effectiveness comparison of on-line index and on-line abstract systems for various levels of demand and recall. (Author)
