Title

¬The relationship between recall and precision

Source

Journal of the American Society for Information Science. 45(1994) no.1, S.12-19

Year

1994

Abstract

Empirical studies of retrieval performance have shown a tendency for Precision to decline as Recall increases. Examines the nature of the relationship between recall and the number of documents retrieved, between precision and the number of documents retrieved, and precision and recall are described in the context of different assumptions about retrieval performance
