ABSTRACT
We propose a simple method for converting many stan-
dard measures of retrieval performance into metasearch al-
gorithms. Our focus is both on the analysis of retrieval mea-
sures themselves and on the development of new metasearch
algorithms. Given the conversion method proposed, our ex-
perimental results using TREC data indicate that system-
oriented measures of overall retrieval performance (such as
average precision) yield good metasearch algorithms whose
performance equals or exceeds that of benchmark techniques
such as CombMNZ and Condorcet.
