ABSTRACT:
Patent search is an example of recall-oriented search where the Cranfield Paradigm with its emphasis on (early) precision falls short of what is needed. Since recall is impractical to measure, we propose a measure of document and corpus access, retrievability, which when combined with precision can give insights into the recall-oriented search problem. Empirical results based on patent collections are presented.
