Presenting Results of Experimental Retrieval Comparisons.
Peer reviewed Peer reviewed
Keen, E. Michael – Information Processing and Management, 1992
Various methods for calculating and presenting results of information retrieval (IR) evaluation research are discussed, with illustrations from recent laboratory results. Highlights include measures for calculating recall and precision, user needs for high or low level of recall, and comparisons of Boolean and ranked output retrieval. (22…

A Performance Measurement and Evaluation Environment for Information Systems.
Peer reviewed Peer reviewed
Dominick, Wayne D. – Information Processing and Management, 1987
Describes the concept of an integrated environment which allows managers to evaluate and measure the performance of computer based information systems. Both system efficiency evaluation and user interaction evaluation are addressed, and MADAM, a system currently operational at the University of Southwestern Louisiana, is briefly described.…

On the Evaluation of IR Systems.
Peer reviewed Peer reviewed
Robertson, S. E.; Hancock-Beaulieu, M. M. – Information Processing and Management, 1992
The increasing complexity of evaluating information retrieval (IR) systems is discussed in terms of contributing factors and research methods. Examples are provided from experiments with weighted searching on a front-end system, information-seeking behavior and online catalogs, and the OKAPI experimental retrieval system.

Information Retrieval Evaluation in Practice: A Case Study Approach.
Peer reviewed Peer reviewed
Smithson, Steve – Information Processing and Management, 1994
Outlines problems involved in information retrieval evaluation and suggests a more user-centered interpretive approach. A longitudinal study that examines evaluation through the information-seeking behavior of 22 case studies of actual users is described; and relevance judgments, effectiveness ratios, and analysis of document failures are…
