17. A system according to claim 10 , further comprising: a training module to train a classifier by analyzing the further classification codes, wherein the further classification codes are received from one or more users.
10. A computer-implemented system for generating a training set for use during document review, comprising: an assignment module to assign classification codes to a set of documents; a classification receipt module to receive further classification codes assigned to the same set of documents; a comparison module to compare the classification code for at least one document with the further classification code for that document; a determination module to determine whether a disagreement exists between the assigned classification code and the further classification code for at least one document; an identification module to identify those documents with disagreeing classification codes as training set candidates; a training set module to apply a stop threshold to the training set candidates and to designate the training set candidates as a training set when the stop threshold is satisfied, wherein the stop threshold comprises one of a percentage of disagreement, a number of documents with disagreeing classifications, and a zero-defect test; and a processor to execute the modules.
