Author(s)
Ellen M. Voorhees
This paper demonstrates that, for large-scale tests, the match and non-match similarity scores have no specific underlying distribution function. The forms of these distribution functions require a nonparametric approach for the analysis of the fingerprint

The Effect of Topic Set Size on Retrieval Experiment Error

August 1, 2002
Author(s)
Ellen M. Voorhees, C E. Buckley
Retrieval mechanisms are frequently compared by computing the respective average scores for some effectiveness metric across a common set of information needs or topics. Since retrieval system behavior is known to be highly variable across topics, good
