摘要: Abstract Most automated information retrieval systems operate by relating a document to request means of measure pertinance, and then retrieving the most pertinent documents for their patrons. In this paper consistency operating procedure with well known Swets Model is examined. It shown that accepting assumptions made would result in possible rejection favor those are less pertinent.
