Which of the following best describes a negative coding label?

A negative coding label is used to signify that a particular document is not relevant to the review process. In the context of document review, especially in legal or compliance scenarios, identifying irrelevant documents is crucial for streamlining the review process and ensuring that only pertinent information is evaluated. By assigning a negative coding label, reviewers communicate that the document does not meet the criteria necessary for inclusion in the relevant dataset, thus helping to focus resources and efforts on more pertinent materials.

The other choices highlight different aspects of document relevance, but they do not accurately define the function of a negative coding label. Identifying a document as highly relevant or needing further review suggests a positive engagement with the document's contents, while undetermined relevance indicates uncertainty, which does not align with the clear indication provided by a negative coding label.
