Patent ID: 8909640

Claim:
A system for propagating classification decisions, comprising: a corpus of unclassified documents; a sample of the unclassified documents selected for review by a user based on a probability that each unclassified document includes responsive text, a probability that the unclassified document fails to include responsive text, and a level of precision; a sample module to provide the sample of unclassified documents to the user; a classification module to classify one or more of the unclassified documents in the sample by assigning a classification code to each of the one or more unclassified documents in the sample based on instructions from the user; an identification module to identify those unclassified documents in the corpus that are similar to the classified documents; an assignment module to assign the same classification code of the classified documents to each of the similar unclassified documents; a validation module to perform validation of the similar unclassified documents, comprising: a sample selection module to select a further sample of unclassified documents from the corpus of unclassified documents; a size determination module to determine a size of the further sample based on a confidence level and upper bound of unclassified documents remaining in the corpus; a responsive determination module to determine that one or more of the unclassified documents in the further sample have responsive subject matter; and a review module to perform further review of the unclassified documents in the corpus when at least one of the unclassified documents in the sample has responsive subject matter; and a processor to execute the modules.
