Testing of the hypothesis that good precision-recall performance can be based entirely on proximity relationships is a focus of current TREC work at ANU. PADRE's \Z-mode" method (based on proximity spans) of scoring relevance has been shown to produce reasonable results for hand-crafted queries in the Adhoc section. It is capable of producing equally good results in database merging and routing...
