Patent US 10,242,001

Systems and methods are provided for classifying electronic information and terminating a classification process which utilizes Technology-Assisted Review (“TAR”) techniques. In certain embodiments, the TAR process, which is an iterative process, is terminated based upon one more stopping criteria. In certain embodiments, use of the stopping criteria ensures that the TAR process will reliably achieve a level of quality (e.g., recall) with a certain probability. In certain embodiments, the TAR process is terminated when it independently identifies a target set of documents. In certain embodiments, the TAR process is terminated based upon whether the ratio of the slope of the TAR process's gain curve before an inflection point to the slope of the TAR process' gain curve after the inflection point exceeds a threshold. In certain embodiments, the TAR process is terminated when a review budget and slope ratio of the gain curve each exceed a respective threshold.
