Title

¬A critical investigation of recall and precision as measures of retrieval system performance

Source

ACM transactions on information systems. 7(1989) no.3, S.205-229

Year

1989

Abstract

Recall and precision are often used to evaluate the effectiveness of information retrieval systems. However, when the retrieval results are weakly ordered, in the sense that several documents have an identical retrieval status value with respect to a query, some prohabilistic notion of precision has to be introduced. Provides a comparative analysis of methods available for defining precision in a prohabilistic sense and to promote a better understanding of the various issues involved in retrieval performance evaluation.
