Title

Robustness of well-designed retrieval performance measures under optimal user behavior

Abstract

Considers a simple model of an information retrieval technology, and uses this model to examine performance measures for information retrieval systems. If an user is employing and information retrieval system optimally, then reasonable performance measures will tend to be relatively robust, or insensitive, to small variations in assumptions about the user's behaviour. Reports a simple empirical illustration of this approach, though more work will be needed to determine exactly how robust performance measures will be in practical application
