In the context of Review validation, what does the term 'Recall' refer to?

In the context of Review validation, 'Recall' specifically refers to the ability to identify all relevant documents from the total number that genuinely are relevant. Therefore, the percentage of documents coded as relevant out of the total number of relevant documents effectively captures the essence of recall. High recall indicates that a significant portion of the actual relevant documents has been retrieved, which is crucial for ensuring thoroughness in document review.

This measure is integral to assessing the performance of a review process, particularly in legal and compliance settings, where missing relevant documents can have significant implications. By focusing on the proportion of correctly identified documents within the total pool of relevant documents, this definition aligns with standard metrics used in information retrieval and document review contexts.

The other options, while related to the concepts of validity and discovery in review processes, do not accurately define recall in this context. They refer to other aspects of document review or different metrics that assess document relevance and discovery efficiency. Thus, the foundational understanding that recall measures the percentage of relevant documents correctly flagged in the review is key to grasping its importance in this field.
