With large information systems, like the World Wide Web on the Internet, recall is almost impossible to measure or estimate by all standard techniques. A proposal \u2018needle hiding\u2019 is made as a technique to estimate recall. It is also shown that ranking by relative recall does not have to be isomorphic to ranking by recall; hence the use of relative recall for comparative evaluation might not be entirely sound.<\/jats:p>","DOI":"10.1177\/016555159802400604","type":"journal-article","created":{"date-parts":[[2004,12,17]],"date-time":"2004-12-17T20:36:35Z","timestamp":1103315795000},"page":"409-417","source":"Crossref","is-referenced-by-count":18,"title":["Measuring recall"],"prefix":"10.1177","volume":"24","author":[{"given":"Martin","family":"Frick\u00e9","sequence":"first","affiliation":[{"name":"University of Arizona, USA,"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[1998,12,1]]},"reference":[{"key":"atypb1","doi-asserted-by":"publisher","DOI":"10.1002\/(SICI)1097-4571(199601)47:1<4::AID-ASI2>3.0.CO;2-3"},{"key":"atypb2","doi-asserted-by":"publisher","DOI":"10.1108\/eb051463"},{"key":"atypb3","first-page":"276","volume-title":"Application for Grant to the National Science Foundation","author":"C.W.
