When responding to a subpoena, request for production, or other document demand, Dagger categorizes documents as relevant or non-relevant. The great bulk of documents are typically non-relevant. Depending on the nature of the document set and client needs, there may be a third, residual group of documents: those which the software cannot categorize to the requisite accuracy. Armed with these three groups of documents, the client can disregard or lightly sample the non-relevant group (typically the great majority), produce the relevant group with or without prior screening, and review the uncategorized residuum in its entirety. This methodology enables the client to minimize the population of documents requiring expensive and time-consuming human review.
