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.
