Abstract
A method and apparatus for determining the veracity of data. The method includes at least one comparison of manually input data and data generated by an automated process. The data generated by the automated process is typically the result of optical character recognition (OCR) and includes the generation of both classification of the optically read data as well as confidences for the data. For each piece of data processed by the OCR, the OCR program will generate a classification, which is a guess by the OCR program as to what that piece of data is, and a confidence level, which is the OCR's evaluation of how good the classification guess was. Depending on whether it is desired to check the accuracy of the manually input data or the results of the optical character recognition determines how the data is compared. The low confidence data is typically re-keyed into the system manually. To perform quality assurance on the manually input data, one compares the results of the optical character recognition with the manually input data. If they match, the manually input data is determined to be accurate and passes a quality assurance test. If they do not match, a second operator inputs a…
