Title

Performance standards and evaluations in IR test collections : cluster-based retrieval models

Abstract

Computes low performance standards for the group of queries in 13 retrieval test collections. Derived from the random graph hypothesis, these standards represent the highest levels of retrieval effectivenss that can be obtained from meaningless clustering structures. Compares operational levels of cluster-based performance reported in selected sources during the past 20 years to the standards. Typical levels of operational cluster-based retrieval can be explained on the basis of change. Most operational results in retrieval test collections are lower than those predicted by random graph theory. Clustering strategies capable of adapting to relevance information may succeed where static clustering techniques have failed
