The purpose of this communication is to suggest that in the situation where documents are retrieved independently the desired parameters may be estimated more accurately by sampling and averaging techniques over homogeneous subparts of the data base. It is also suggested that certain changes in the nomenclature of the parameters would help to avoid ambiguities in their interpretation.<\/jats:p>","DOI":"10.1002\/asi.4630230510","type":"journal-article","created":{"date-parts":[[2007,6,27]],"date-time":"2007-06-27T15:54:22Z","timestamp":1182959662000},"page":"333-334","source":"Crossref","is-referenced-by-count":1,"title":["Retrieval parameters in growing data bases"],"prefix":"10.1002","volume":"23","author":[{"given":"Richard S.","family":"Marcus","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2007,3,22]]},"reference":[{"key":"e_1_2_1_2_2","doi-asserted-by":"crossref","unstructured":"Salton G.
