RECALL
  1. Context:
    Searching


    Definition:
    A measure of the effectiveness of a search expressed as the ratio of the number of relevant records or documents retrieved in response to the query to the total number of relevant records or documents in the database; for example, in a database containing 100 records relevant to the topic "book history," a search retrieving 50 records, 25 of which are relevant to the topic, would have 25 percent recall (25/100).
