We compare the performance of two database selection algorithms reported in the literature. Their performance is compared using a common testbed designed specifically for database selection techniques. The testbed is a decomposition of the TREC/TIPSTER data into 236 subcol-lections. The databases from our testbed were ranked using boththegGlOSS and CORI(More)
We describe a testbed for database selection techniques and an experiment conducted using this testbed. The testbed is a decomposition of the TREC/TIPSTER data that allows analysis of the data along multiple dimensions , including collection-based and temporal-based analysis. We characterize the subcollections in this testbed in terms of number of(More)
