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.

Dr. Richard Bache is a senior researcher at the Department of Computer and Information Science of the University of Strathclyde in Glasgow, UK.
He is currently working on the EPSRC project iMOV on geographical and behavioural profiling of serial crimes using information retrieval and text mining techniques. Previously he worked with Amazon at their research lab in Edinburgh. He holds a PhD in Software Engineering.
