Abstract
Presents a new measure of retrieval evaluation, called 'corrected precision', which attempts to refine the traditional precision measure by taking account of differences between users in their selectivity when judging the relevance of documents. Presents the formula for calculating corrected precision and brief remarks about its development and use, advantages and disadvantages, and summary statsitics comparing the 2 from an empirical study of relevance
