Abstract
The variety of performance measures available for information retrieval sys tems, search engines, and network filtering agents can be confusing to both practitioners and scholars. Most discussions about these measures address their theoretical foundations and the characteristics of a measure that mak e it desirable for a particular application. In this work, we consider how measures of performance at a point in a search may be formally compared. Cr iteria are developed that allow one to determine the percent of time or con ditions under which two different performance measures suggest that one doc ument ordering is superior to another ordering, or when the two measures di sagree about the relative value of document orderings, As an example, graph s provide illustrations of the relationships between precision and F.
