Recall

Definition(s)

  • Recall measures the number of responsive documents retrieved compared to the total number of responsive documents in the corpus. Recall cannot be absolute unless all documents have been searched and all have been reviewed. Since Recall measures the ratio of responsive documents against the full corpus, the number of responsive documents in the corpus is difficult to determine. See the EDRM Search Guide regarding precision, recall, and sampling for more information. See also, Precision.
  • The fraction of Relevant Documents that are identified as Relevant by a search or review effort. 1
  • The proportion of responsive documents in the entire collection that have been retrieved. 2
