On the Foundation of Evaluation.
Shaw, W. M., Jr.
Journal of the American Society for Information Science, v37 n5 p346-48 Sep 1986
The derivation of a general retrieval effectiveness measure is investigated. Inconsistencies in the definition of relative importance are resolved, and it is shown that the influence of the assigned weight on the effectiveness measure can produce counterintuitive results. An alternative effectiveness measure provided by the Marczewski-Steinhaus metric is recommended. (Author/EM)
